For recent years, many areas have begun to implement the technology of small silkworm co-breeding, to put it bluntly, small silkworm co-breeding is to let 1-3 years old silkworm centralized management, mainly to find a co-breeding room of different sizes for management, to the 3-year-old silkworm, and then will be distributed to the hands of various farmers, and finally farmers from the 3-year-old silkworm began to breed, so that the main shortening of the breeding time, in addition to improving the management of the small silkworm sleeping period, but at present, the sericulture technology varies around the world. Although the co-breeding model of small silkworms is good, sericulture households are less worried, but there is no technology or not, so small silkworm co-breeding is still aimed at the breeding level of sericulture households.
Especially in terms of this year's epidemic, it is also a relatively long time, resulting in a lot of areas in a state of blockade, mainly due to the impact of the epidemic, resulting in the inability to manage the mulberry garden in time, plus in recent years, many farmers have changed their profession, so the technology may be different, of course, there are novice farmers, for the breeding technology is still lacking, once in the small silkworm co-breeding, if you do not control the sericulture, then the loss will be relatively large, Therefore, in this article, we mainly explain how to better control the daily sleep of small silkworms in the co-breeding mode of small silkworms, so that small silkworms have a better sleeping period and increase the income of our farmers.
<h1 class= "pgc-h-arrow-right" > first, the temperature requirements during silkworm co-breeding</h1>
1, the temperature of the small silkworm period is basically understood
For many months of the year for the small silkworms are not conducive to the growth of small silkworms, so in the jam room temperature regulation, we must be prepared accordingly, for example, these days there has been a substantial cooling in the Shandong region, so for the spring sericulture households should also pay attention to adjust the temperature, to avoid problems in the small silkworm sleep period caused by low temperatures, which will lead to sericulture stunting during the emergence of various silkworm diseases, especially when the temperature is lower than 10 degrees, the harm will be very large will cause losses to our farmers. From May to October every year, this period is the hottest, the temperature is basically above 20 degrees to about 36 degrees, during this period it is difficult to control the sleeping period of breeding silkworms, which is to be noted.
Secondly, after November to March of the following year, because this time is relatively cold, especially around March, it is easy to appear spring cold, so this time also to control the temperature, when the temperature is low, it is necessary to heat the silkworm room, especially when the 1-2 years old silkworm, the temperature is below 20 degrees, it is necessary to heat the treatment in time, so as not to cause the sericulture of low temperature, and overall low temperature and high temperature are not conducive to the day sleep management of the silkworm.
2, always pay attention to the management of the temperature of the small silkworm period
Because in recent years, the use of small silkworm co-breeding mode has a lot of sericulture households have begun to implement, so in the small silkworm co-breeding will appear when the small silkworm co-breeding period, the breeding density of small silkworms is relatively large, whether it is in the spring and summer breeding and autumn and winter breeding of small silkworms, the temperature demand is a great impact, for small silkworms, only the temperature is well controlled, the silkworm is a time to control the sleep, for the temperature of the silkworm room in the cold time to pay attention to increasing the temperature, the silkworm room can increase the heating equipment, However, in recent years, many areas have adopted a more convenient method, using air conditioning or heaters, but for small co-breeding rooms, such equipment will increase the cost of expenditure after all, we can use wood in the silkworm room and the like and then heat up, so that you can reduce the cost of expenditure, in addition to installing exhaust fans in the silkworm room, you can exhaust cooling when it is hot, which is also a relatively small cost.
For the small silkworm in the temperature after the harvest of ants is more important, especially in the small silkworm after the harvest of ants within 5-6 days to adjust the temperature of the jam room, in addition to the small silkworm harvest ants to the 4 instar period to follow the change of the weather, timely temperature control, for the small silkworm sleep temperature adjustment, I want to understand and master the temperature in time, generally when the temperature is below 20 degrees, the silkworm will generally have little feeding and activity, then this time to increase the temperature in time, when the temperature of the silkworm room in 21 degrees to 27 degrees, At this time, it takes 4 days for the 1-year-old silkworm to sleep after harvesting ants, 3 days for the 2-year-old silkworm to sleep, and 4 days for the 3-year-old silkworm to sleep, especially during the period of time for the 1-year-old silkworm and the 3-year-old silkworm, the mulberry leaves should be fed in time at night to avoid the appearance of 1-year-old silkworm and 3-year-old silkworm stunt, resulting in poor sleep.
When the temperature exceeds 32 degrees, this time is to cool down, if the continuous high temperature, then the silkworm will be difficult to enter sleep, the day sleep will have problems, when the temperature is between 27-32 degrees, this time is an important temperature that can improve the daily sleep management of the silkworm, this time when the 1-year silkworm from the harvest of ants to sleep when it takes 3 days, the 2-year-old silkworm from the feeding to sleep takes 2 days, the 3-year-old silkworm sleep will be in 4 days, this temperature is more appropriate, the sleep of the silkworm is also very good.
3, timely adjustment of the time of harvesting ants
For the traditional harvest time, it also affects the sleep of the silkworm, so we have to adjust the time of income in a timely manner, so as to improve the day sleep management of the silkworm, I can change the time of harvesting ants in the morning to the time of harvesting ants in the afternoon, we can carry out the greening of silkworm seeds according to the plan, carry out dark treatment after the silkworm seed is greened, the day of harvesting ants is not lighted, and at 5-6 pm, the ants are collected, so that the 1-year-old silkworms will fall asleep on the fourth day. On the fifth day, it will be fed, which can delay the harvest of ants and promote the rapid dormancy of the silkworms.
< h1 class= "pgc-h-arrow-right" > two, the control of sunlight sleep facilities in the silkworm co-breeding room should be perfected</h1>
For the small silkworm co-breeding room, mainly to control the small silkworm sleeping period of the facilities to improve, from the current small silkworm co-breeding facilities, I personally still recommend the use of small co-breeding room, such a co-breeding room has a better advantage, because in the small co-breeding room for management 1-3 years old silkworms can be well controlled, after all, the small co-breeding room breeding is less, better management, but the facilities of the co-breeding room should be perfected, such as the dry and wet thermometer of the summer silkworm co-breeding room should be equipped, In this way, you can always observe the temperature and humidity of the jamsil room in order to ventilate in time, especially when the jam room uses plastic film to cover the silkworm seat, it is necessary to open a hole in the film for ventilation, and the silkworm frame of the jam room cannot be stacked too high, and maintaining a certain distance can avoid stunting due to temperature differences.
When breeding 1-3 years old silkworms, silkworm farmers should feed high-quality mulberry leaves to the silkworms in time, and the mulberry leaves of the small silkworms should also be fed mature leaves with good leaf quality development, and the mulberry leaves recovered from the harvest should also be properly preserved, it is best to do a good job of timely feeding, to avoid improper storage of mulberry leaves caused by pollution of mulberry leaves, in the daytime can be normally carried out in accordance with the feeding time, generally feeding 3-4 times a day, to 12 o'clock at night when feeding once, so that the silkworms will eat the mulberry leaves evenly, a lot of sleep, At 8-9 o'clock in the morning, sprinkle the lime again, and the silkworm will sleep.
<h1 class= "pgc-h-arrow-right" > three, the management measures for silkworm dormancy</h1>
1,1 year old silkworm period daily sleep temperature regulation
In the 1st year silkworm, because the size of the silkworm is relatively small, the silkworm seat at this time is also relatively small, in addition to the small silkworm sleep period is generally more than 24 hours, this time is better to grasp the temperature, this 1-year silkworm sleep period, the temperature of the silkworm room is controlled at about 25-28 degrees, the temperature can not be too high nor too low, this temperature can be maintained until the 1st year old silkworm sleeps and wakes up, which can make the time of small silkworm breeding shortened to 3 days, to achieve a better sleep period. (Do not open the doors and windows arbitrarily during this period to avoid lowering the temperature)
2, 2-year-old silkworm period daily sleep temperature regulation
On the fourth day after the small silkworm harvests the ants, the 2-year-old silkworm will be fed, at this time the development time of the 2-year-old silkworm is relatively short, the sleeping period is more than 10 hours, the random 2-year-old silkworm is the focus of temperature regulation, the temperature of the 2-year-old silkworm must be maintained at about 28 degrees, this time do not divide the silkworm in advance, should be kept until the 2-year-old silkworm sleep period wakes up, or the sericulture room cooling, so that you can extend the sleep period of the 2-year-old silkworm to postpone the half day, and then let the small silkworm on the fourth day change to the afternoon feeding, It can make the 2-year-old silkworm better spend the sleep period, and the temperature of the 2-year-old silkworm must be maintained between 27-32 degrees to better control the day sleep. If the temperature is low, it will be difficult for the silkworm to reach the time of sleep, and if the temperature is too high, it will cause the silkworm to fall asleep late, and may also lead to the occurrence of silkworm night sleep.
3,3 years old silkworm period daily sleep temperature regulation
From the experience point of view, the 1-3 years of silkworms appear in the day sleep instability is mainly caused by 1-2 years old silkworms, if the temperature control of the small silkworm period is not good, then the sleep period of the 3-year-old silkworm will increase, there will be uneven sleep period, mainly in the 1-2 years of the silkworm sleep period regulation, then the 3-year-old silkworm's daily sleep will be controlled, after all, the size of the 3-year-old silkworm is relatively large, the development time is relatively long, the sleep period is also very long, the sleep period will exceed 24 hours, For the regulation of the day sleep of 3-year-old silkworms, keeping the temperature at about 20 degrees can breed 3-year-old silkworms, so 1-2 year old silkworms are the key to breeding.
Summary of the key points: for the breeding of small silkworms, we still have to advocate a good, small silkworm 1-3 years of the day sleep management, only the small silkworm period management can achieve the management of the large silkworm period, but also can save us half of the matter, but in the breeding of 1-3 years old silkworms should also pay attention to the most important is the temperature regulation, after all, the small silkworm period of the day sleep management is very important, mainly throughout the year the temperature changes greatly. When we are in the small silkworm breeding period, we must strengthen the environmental management around the silkworm room, especially in the small silkworm period, strengthen the illumination of the silkworm room, and also realize the management of improving the sunlight as soon as possible.
