Many farmers in the silkworm breeding, sometimes encounter an abnormal situation, almost time to sleep silkworms, wake up time is quite different, less interval of 4 hours, more interval of more than 8 hours, especially more than 4 years of silkworms, due to the sleep period is relatively long, this phenomenon will be more obvious. If there is uneven sleep in the 3-year-old silkworm stage, and the number of silkworms sleeping late is more, accounting for more than 10%, then the 4-5-year-old silkworm period, the time of sleep will be 1-2 days apart, and the awakening time will often be delayed, and when the 5-year-old silkworm is on the tung in the later stage, the time difference between the mature silkworm and the silkworm may be expanded to 2-3 days. Obviously, such a phenomenon will increase the workload of farmers, sand removal, increase the difficulty of silkworm seats and other links, once the treatment is not in place, it is easy to appear weak silkworms, weak physique will also induce a variety of silkworm diseases.
From another point of view, uneven sleep reflects the difference in the growth and development of silkworms, and silkworms with weak constitutions often wake up late, some because the daily management of farmers is not in place, and some are caused by pathological factors. The proportion of uneven sleep is within 5%, the impact on the time of late ripe silkworms will not be great, but if the number of uneven sleep reaches more than 20%, especially when the 5-year-old silkworm wakes up, then when the 5-year-old silkworm is on the mole, it may be divided into multiple batches, the sleep time difference is more than 10 hours, the time of the silkworm will be different by 1-2 days, once the farmer does not do a good job of greening, after using molt hormone, some of the unripe silkworms will continue to eat mulberry leaves, at this time, the farmers need to pick out and arrange the upper silkworms. The workload will increase significantly. When raising silkworms, what factors can cause uneven sleep? Personally, I think it is mainly related to the following five aspects.
<h1 class="pgc-h-arrow-right" >, sleep without eating</h1>
When the silkworm is about to fall asleep, the amount of mulberry leaves is slowly decreasing, until the stop eating, some farmers at this time on the amount of mulberry leaves to grasp is not very good, think that the amount of mulberry leaves controlled at about 1 layer can be, and some farmers mulberry leaves although the amount of control at more than 1.5 layers, but the overall mulberry leaves are old, when the silkworm has fallen asleep, the remaining mulberry leaves in the silkworm seat are also more. In fact, these two phenomena have problems, the amount of mulberry leaves is insufficient or the mulberry leaves fed are old, it is easy to make the silkworms can not eat enough to sleep, the sleep period is the time when the silkworm tissues and organs have undergone greater changes, better physical strength is needed, if you are in a state of hunger when you fall asleep, then it is not surprising that the sleep time is delayed, this factor can actually be improved, only need to pay attention to some details.
<h1 class="pgc-h-arrow-right" > second, the temperature and humidity in the silkworm room during sleep are improperly controlled, inducing silkworm disease</h1>
Some farmers want to understand, silkworms before going to sleep, the overall growth is still relatively good, and the time to sleep is more consistent, basically within 2 hours of falling asleep, but when there is a wake-up sleep, the individual difference is more obvious, the silkworm that wakes up first and the silkworm that wakes up after the sleep, the time difference is more than 6 hours, some even more than 8 hours, and some directly do not wake up. In fact, most of this is caused by silkworm disease, some silkworms have been recruited before falling asleep, but the pathogens parasitic in the silkworm body have not been shown, and during the sleep period, the temperature in the silkworm chamber exceeds 28 ° C for a long time, and the relative humidity is greater than 90%, which induces some silkworm diseases, thus making the difference in sleep time obvious. Once the sleep is uneven due to silkworm disease, farmers should find a way to raise the sick silkworms separately, and the symptoms are more obvious, and they must be willing to be eliminated.
<h1 class="pgc-h-arrow-right" > third, the light in the silkworm room is uneven</h1>
Some farmers believe that the light problem in the silkworm house does not seem to be a big problem, as long as it is not directly illuminated by the noon sunlight, in fact, this seemingly inconspicuous factor sometimes brings a more obvious impact on the growth of silkworms. In the 3-year-old silkworm above, the silkworm seat in the silkworm room has increased, when the placement position is not appropriate, some of the silkworm seat light is stronger, from 11 am to 14 pm, the sunlight can also shine in the silkworm seat, and some of the silkworm seat is placed in the corner, and the door and window have a certain distance, the overall light is dim. This contrast is also easy to make the silkworm sleep time inconsistent, in general, the light is stronger, the awakening time is earlier, and the light is dim, the awakening time will be appropriately late, this abnormal situation, the later stage is necessary to take certain measures to prevent.
<h1 class= "pgc-h-arrow-right" > fourth, there is a phenomenon of large and small silkworms in the early breeding process</h1>
For farmers, they do not want to have the phenomenon of large and small silkworms in their hearts, because this will increase the difficulty of daily management, but from the actual situation, the early management of farmers is not good enough, such as not removing sand in time and expanding the seat, resulting in excessive feeding density, invisibly forming large and small silkworms. If after the 2-year-old silkworm, there will be a phenomenon of large and small silkworms, and before the silkworm falls asleep, the silkworms with obvious individual differences are not raised separately, or the artificial judgment is not accurate enough, then in the 3 sleep, 4 sleep, the time of sleep will be significantly different, and the interval time difference of more than 12 hours is also possible. Generally speaking, the phenomenon of large and small silkworms in the small silkworm stage is not too obvious, mainly after the 4th year of silkworms, some farmers are too busy to increase the number of silkworm seats in time, and the growth and development of silkworm bodies is faster, there will be differences in sleep time and sleep time, and there will be differences in the later management to find ways to be weak and small, otherwise the time of onset will also be significantly different.
<h1 class = "pgc-h-arrow-right" >5, some silkworms are frightened during sleep and wake up early</h1>
When silkworms start to sleep, they need a relatively quiet environment and cannot have noise, otherwise it will affect the quality of sleep. This is also very understandable, just like the baby nap, under normal circumstances to sleep more than 2 hours, if in its sleep, there are constantly sharp sounds around, or from time to time to make a loud noise, then the baby sleep will not be very steady, easy to turn over, sometimes less than 1 hour to wake up. Silkworms in sleep, is also a similar situation, for example, under normal circumstances to 12 hours to wake up, and the inside or around the silkworm room, there are often some sharp sounds, such as cutting tiles, sawn timber, etc., then it will also affect the sleep time of silkworms, early awakening is also possible. Throughout the sleeping period, farmers should ensure that the environment inside and around the silkworm house is relatively quiet and reduce the noise caused by human factors.
Usually, silkworms wake up and sleep time span is large, farmers should pay attention to, analyze the specific causes of this phenomenon, if it is caused by human factors, then the later stage needs to be corrected, if it is because some silkworms have symptoms of disease, then it is necessary to remove sand in time, and healthy silkworms and abnormal silkworms are raised separately. Especially into the 4-5 years old silkworm period, sleep time of more than 4 hours, it is likely to be a precursor to the emergence of silkworm disease, if necessary, the silkworm that wakes up too late to be eliminated, the late stage of the silkworm room, silkworm body and other disinfection links should be further strengthened, the original disinfection only once a day, to increase to 3-4 times a day disinfection, in addition, you can also spray the appropriate amount of antibiotics on the silkworm body or mulberry leaves to enhance the silkworm body physique. In order to make the sleep time of the silkworm relatively consistent, what do farmers need to do well? Personally, I think it is important to implement the following 7 points.
1. Select excellent silkworm species to shorten the incubation time of ant silkworms
Some silkworm species due to different characteristics, climatic conditions vary greatly, prone to uneven development of silkworm body phenomenon, if farmers encounter this situation, even if the later management is done well, it is difficult to completely avoid. Therefore, in order to reduce the phenomenon of uneven sleep, farmers should understand the adaptability of silkworm seeds in advance when choosing silkworm seeds, and try to buy in places with similar climatic conditions, such as farmers themselves in a place with a dimension of 21 °, while the production enterprises of silkworm seeds are in a place with a dimension of 35 °. Of course, this situation farmers can do some understanding in the early stage, in general, the local formal channel unified booking of silkworm species rarely this phenomenon, because the relevant parties will do some assessment in advance to ensure that silkworm seeds are suitable for local breeding. When hatching silkworm seeds, the temperature and humidity in the silkworm room should be properly controlled, the temperature should be 27-28 ° C, the time of harvesting ants should not be too long, the spring silkworms and late autumn silkworms should not exceed 10 a.m., the harvesting time of summer silkworms and mid-autumn silkworms can be before 8 a.m., when the incubation time of the silkworms is relatively neat, the neatness of the late sleep is relatively high.
2. Strictly control the breeding density of silkworms of all ages
Some farmers in the 1-2 years old silkworm period, due to careful care, all aspects are small winged, the growth and development of the silkworm body is more normal, when the silkworm body wakes up, it is not found that the interval is very different, basically within 2 hours, and from the 3-year-old silkworm, the individual difference begins to stand out, some silkworms fall asleep first, but also wake up first, and some silkworms have a certain lag. In fact, this has a greater relationship with the breeding density, after the 3-year-old silkworm, the growth and development of the silkworm body is faster, if the farmer does not remove sand in time, and appropriately increase the silkworm seat, then some silkworms can not eat mulberry leaves normally, sometimes full of hunger, a long time is easy to form large and small silkworms, the growth and development of the silkworm with differences in the same silkworm seat sleep, sleep uneven is more normal. If farmers strictly control the feeding density at all ages of silkworms, start from the 2nd year old silkworm to remove sand in time, and appropriately increase the number of silkworm seats, then the phenomenon of large and small silkworms in the later stage is relatively rare, and the waking time will be relatively consistent.
3. Appropriately increase the amount of mulberry leaves before falling asleep
When the silkworm is about to fall asleep, the speed of eating mulberry leaves will decrease, and the amount of mulberry leaves will also be reduced, but it should be noted that the amount of mulberry leaves cannot be significantly reduced at this time, such as the 4-year-old silkworm stage, each time you need to feed 2-2.5 layers of mulberry leaves, and only feed about 1 layer of mulberry leaves before falling asleep, then it is obvious that some silkworms are not full. Once the silkworm sleeps without full food, then some silkworms with weak physique may behave abnormally, sometimes waking up early, sometimes extending the sleep period, bringing great trouble to the daily management of farmers. Therefore, farmers should control the amount of mulberry leaves before falling asleep, in general, although the amount of mulberry leaves before falling asleep should be appropriately reduced, it should not be lower than 80% of the full food period. Especially 3 sleep and 4 sleep, at this time the amount of mulberry leaves fed should not only be relatively sufficient, basically feed 1.5-2 layers, and the feeding mulberry leaves should not be old, but should be appropriately tender, which is conducive to enhancing the appetite of the family, and the physique will be relatively better.
4. The light in the silkworm room is kept relatively uniform to avoid direct light
Many times, the growth and development of silkworms is abnormal, and the light in the silkworm room has a greater relationship, this is because the silkworm in different periods, the sensitivity to light is different, such as 1-5 years old silkworm period, some places in the silkworm seat light is stronger, then the surrounding other silkworms will move closer to here, and when the silkworm is close to the cocoon, it will be far away from the strong light, but will find some places with weak light to spit silk as a cocoon, the light problem in the silkworm room is easy for many farmers to ignore. 1-2 years old silkworm period, the required silkworm seat is relatively small, most of the space in the silkworm house is idle, at this time there will be little uneven light, and from the beginning of the 3rd year old silkworm, the silkworm house increased more and more silkworm seats, some silkworm seats close to the window, some close to the corner, if the farmer usually does not pay attention to these, then it will be found that there is a difference in the growth of the silkworm body. There are also certain ways to solve the problem, one is to artificially control the amount of light, the place of the occlusion is blocked in time, and the place that needs to be filled with light is filled in time; the second is to often move the position of the silkworm seat, generally the light and dark places of the silkworm seat for reversion.
5. Do a good job of protection during sleep and strictly prevent interference from external factors
Silkworms enter the sleeping period, at this time the silkworm body looks motionless, it seems that the perception of the outside world is not large, but at this time, if there is a large noise inside the silkworm house, or the silkworm seat is moved too much, it will disturb the silkworm to sleep normally, some silkworms will wake up early, the sleep period experienced in insufficient time, the growth and development of the silkworm will be affected. Whether it is in the 1-3-year-old silkworm stage, or the 4-5-year-old silkworm stage, every time the silkworm sleeps, the farmer must keep the inside and surrounding of the silkworm house relatively quiet, there must be no obvious vibration sound, and there should be no processing plant within 300 meters around the silkworm house. In addition, if the window is opened for ventilation during the sleep period, it is necessary to pay attention to the amount of ventilation, when the outdoor wind is larger, it is necessary to properly close some of the windows, or temporarily do not ventilate, because once the larger wind blows into the silkworm room, the silkworm seat near the window will have an impact, and some of the silkworm body may be blown, and then wake up in advance. There is also in the sleep protection, do not let mice, cats and dogs into the silkworm house, such animals into the silkworm house, the sound is on the one hand, some will do some destructive actions, this is also to find a way to do some preventive measures.
6. Do a good job of temperature and humidity control in the silkworm room during sleep to avoid silkworm disease during sleep
In the process of raising silkworms, whether in the full food period or the sleeping period, the temperature and humidity in the silkworm room are very important, if the temperature and humidity are abnormal, then the growth and development of the silkworm will also appear abnormal, especially during the sleep period, the resistance of the silkworm will decline, and the changes in the surrounding environment will be more sensitive at this time. In 1 sleep, 2 sleep, the temperature in the silkworm room needs to be controlled at 26-27 °C, the relative humidity is 75%-85%; in 3 sleeps, 4 sleeps, the indoor temperature needs to be maintained at 25-26 °C, the relative humidity is 70-75%. It is necessary to pay attention to the summer silkworm and the mid-autumn silkworm, because the season is prone to high temperature and high humidity weather, which increases the difficulty of temperature and humidity control for farmers, and it is easy to induce some silkworm diseases. Some silkworms sleep at intervals of more than 6 hours, which is related to the emergence of some silkworm diseases, especially those who have been infected by germs before falling asleep, and the state of sleep is even worse, which also requires farmers to take precautions in advance.
7. Grasp the time of sleep and feeding
Generally speaking, there will be a certain difference in the time of silkworm sleep and awakening, which is also a normal phenomenon, after all, the individual physique is different, there will be a succession, but basically there will be no big difference, the time difference is often within 2 hours, and a few are within 4 hours. When some silkworms wake up first, farmers do not rush to feed mulberry leaves, need to observe the activity of silkworms in the silkworm seat, only about 90% of the silkworms begin to find mulberry leaves to eat, farmers can feed relatively tender mulberry leaves, general feeding is controlled at 1-1.5 layers. The control of feeding time is very critical, feeding mulberry leaves too early is easy to appear large and small silkworms, when the release of mulberry leaves is too late, the physique of some silkworms is easy to decline, which is the actual breeding process needs to pay special attention to the place. 1-3 years old sleep period time is relatively short, 4-5 years old sleep period time is relatively long, farmers should be based on the characteristics of silkworm species, estimate the sleep time of silkworms of each age, and then combined with the actual situation to confirm, so that sleep and food control within a reasonable range.
In short, when the silkworm wakes up, the phenomenon of uneven sleep, the interval difference within 2 hours is normal, and the gap can be narrowed by adjusting the feeding time. Of course, if the interval between silkworms sleeping is more than 4 hours, then when farmers sleep and eat, they need to distinguish the silkworms that wake up after sleeping in the sand removal link, raise them together normally, collect them after waking up, raise them alone, and increase the amount of mulberry leaves in the later stage, and sometimes they can also make up for this difference, and the next sleep period may be basically the same. Of course, in order to reduce the phenomenon of uneven sleep, farmers must do a good job in the early stage of prevention, as long as the preliminary work is in place, the time for silkworms of each age to wake up will not vary greatly, the daily management of farmers will be relatively relaxed, the rate of late mature silkworms will be higher, and the income from sericulture will easily meet expectations.
