Many people like to eat radish, but sometimes they find that the radish they grow or the radish they buy back is hollow inside, so that the radish is not only low in yield, but also poor in quality, and the taste is not only rough but also often a little bitter.
Many people may ask: Why are turnips hollow? There are many reasons for the hollowing of radish (the following will be analyzed one by one), but there are two main reasons for radish, one is the insufficient accumulation of nutrient supply when the underground fleshy root of radish is expanded, and the other is the lack of water when the underground fleshy root of radish is expanded.
Perhaps some farmers who grow radish friends may ask again: radish hollowness affects both yield and quality and selling price, so how do we prevent the occurrence of radish hollow problems when we grow radish?
In view of these two major problems, the following agricultural technology small back basket combined with the common causes of radish hollowing, to tell you about the corresponding method of preventing radish hollowing.
First, the hollow radish is related to the choice of varieties
1. Induced causes
Generally speaking, all varieties of radish with relatively large size, shorter growth period and earlier maturity period, the aboveground stems and leaves of radish are stronger than the underground fleshy roots, and the stems and leaves are stronger than the ability of fleshy roots to compete for nutrients, and the underground fleshy roots of these radish varieties are relatively loose in tissue, and the organic nutrient substances are easy to accumulate insufficiently, so if we plant these radish varieties above, it is more likely to have the problem of radish hollowing.
2. Prevention and control solutions
When planting radish to choose varieties, the agricultural technology small back basket recommends that you choose a small, relatively long growing period, medium and late ripening radish varieties, try to avoid choosing large, short growth period, early ripening or very early ripening radish varieties, so that you can avoid the phenomenon of hollowing out of the planting process of planting radish.
Second, the hollow radish is related to the sowing time
The turnips we sow are not prone to hollowing out in the environment of cool daytime and relatively large temperature difference between day and night, because the growth and development rate of aboveground stems and leaves and underground fleshy roots of radish under such environmental conditions is relatively balanced, and underground fleshy roots can slowly increase the supply and accumulation of organic nutrients in the expansion period, so that turnips are not prone to hollowing problems.
On the contrary, if the radish we sow grows in an environment with relatively high daytime temperature and a relatively small temperature difference between day and night (especially the temperature between day and night), the growth rate of radish will be relatively slow, the ability of leaves to produce nutrients will be weakened or stagnated, the nutrients transported by nutrients to the underground fleshy roots will be reduced, and the nutrients of the radish plant will be consumed in large quantities in vain in the high temperature environment, so that it is easy to cause the phenomenon of hollowing out of the radish during the growth process due to the lack of nutrient accumulation of the underground fleshy roots.
When sowing radish, neither the sowing period is too early, nor can the sowing period be too late, according to the season to choose the right time to sow radish, so that the radish growth process as far as possible in the daytime warm, daytime and night temperature difference is larger in the environment, try to make the radish growth avoid the day and night temperature are relatively high and the day and night temperature difference is relatively small period, which can be a good prevention of the problem of hollowing out of the radish. For example, spring planting radish as far as possible around March sowing, summer planting radish as far as possible in May-June sowing, autumn planting radish as far as possible in August and September sowing, because the south and the north in the regional climate conditions are different, so we should choose the most appropriate time to sow radish according to the local climate temperature conditions, try to choose the day and night temperature difference is relatively large season to plant radish as the best.
Third, the hollow radish is related to the sowing density
Radish sowing density is too large, row spacing and plant spacing is too small (especially small plant shape of radish varieties), which will cause radish seedlings to increase the degree of water and fertilizer nutrients between each other, will also reduce the amount of water and fertilizer absorbed by each radish root system, but also cause radish because the growth space is too crowded and narrow, the leaf squeeze each other Light area becomes smaller, the leaf ability to produce organic nutrients becomes poor, in this case, when the fleshy roots under the radish begin to expand and develop, At this time, it is easy to lead to insufficient nutrient transport, supply and accumulation required for the rapid expansion of radish flesh, thus inducing the phenomenon of hollowing out of radish.
On the contrary, if the sowing density of radish is too small, the row spacing and the plant spacing are too large (especially the radish varieties with large plant shape), this will lead to the occurrence of underground fleshy root growth and growth too fast, organic nutrient manufacturing capacity and loose ability in aboveground stems and leaves can not keep up with the problem of stem and leaf growth and fleshy root growth imbalance, and the nutrients manufactured and transported by local upper stems and leaves cannot meet the nutrient requirements of rapid expansion and development of underground fleshy roots, which will lead to the problem of hollowing out of radish.
According to the actual situation of the variety of radish (appropriate dense sowing of small plant shape, appropriate thinning of large plant shape), soil fertility level, etc., the size of row spacing and plant spacing is reasonably adjusted when sowing radish, and a reasonable density is maintained during the growth of radish, so that the problem of hollowing out during the growth of radish can be effectively prevented.
Normally speaking, the optimal density for radish planting is: after the leaves of radish are fully grown and unfolded on the ground, the leaves and leaves can be fully unfolded with each other normally, and there will be no crowding and overlapping occlusion of each other.
Fourth, the hollow radish is related to improper fertilization
It is very important to fertilize rationally during the growth period of radish and maintain a balanced supply of nutrients. If the amount of radish nitrogen fertilizer is used too much, it will stimulate the growth of the aboveground stems and leaves of the radish too much and too fast, and stimulate the radish to pump too early, so that a large amount of nutrients in the radish plant are transported to the growth needs of the aboveground stems and leaves, and the underground fleshy roots are hollowed out during the expansion and development process because of the lack of nutrient accumulation of poor Baba.
In addition, when the radish enters the middle and late stages of rapid expansion and development of underground fleshy roots, if the supply of potassium fertilizer, phosphate fertilizer and boron fertilizer (especially potassium and boron) is insufficient, it will also cause the problem of hollowing out the radish.
In the fertilization management of radish, when sowing, it is necessary to apply sufficient organic fertilizer and phosphate fertilizer, and the amount of nitrogen fertilizer can be appropriately applied before the formation of underground fleshy roots in the early stage of growth, so as to promote the better growth of radishes and robust new roots, the formation of fat leaves for photosynthesis to produce organic nutrients, but when the fleshy roots of radish begin to form and expand, at this time, we must strictly control and reduce the amount of nitrogen fertilizer, and try to increase the application of some phosphorus and potassium fertilizers (especially potassium fertilizers), Diseased leaves are best supplemented by spraying foliar fertilizer 1-2 times of boron fertilizer nutrition in the middle and late stages of radish growth, so as to control the growth of aboveground stems and leaves, and promote the faster and better, more fulfilling and healthier expansion of radish underground meat, which can well prevent the phenomenon of hollowing out of radish.
Fifth, the hollow radish is related to improper watering in the field
When the radish grows to the underground fleshy root expansion and development period, at this time, on the one hand, the aboveground stem and leaf growth is relatively vigorous and needs to consume a lot of water, on the other hand, the rapid expansion of the underground fleshy root needs sufficient water supply, if there is drought and lack of water in the radish field during this period or the phenomenon of soil drying and wetting occurs or the phenomenon of soil before and after wetness occurs, then the radish is not only very easy to cause hollow problems because the underground fleshy root nutrients cannot be transported normally and accumulate, but also the radish that grows out under this humidity condition will be rough flesh, Too many whisker roots, which will have a very big impact on the yield and quality of the radish.
When the radish enters the underground fleshy root expansion period, it is necessary to maintain uniform watering and keep the soil moist at all times (too much watering in the field or excessive soil moisture will cause the radish to rot and fry), can not let the radish soil appear dry and wet, dry and wet, dry and wet, and can not let the radish soil appear high temperature, drought and lack of water, which is one of the simplest and most effective ways to prevent the problem of radish hollowing.
Sixth, the hollow radish is related to improper harvesting
The main reason why improper harvesting will cause turnip hollowness is that there are two main reasons, one is that the harvest time of the radish is too late after the radish is ripe, and the other is that the radish surface is too much damage to the mouth when the radish is harvested.
From the perspective of late harvesting of radish, turnips harvested too late will cause the problem of hollow radish hearts due to the decline of the ability of aboveground leaves to transport nutrients through photosynthetic manufacturing and excessive consumption of nutrients in underground fleshy roots.
From the perspective of radish surface damage, if we are not cautious in the harvesting of radish, resulting in excessive mechanical damage such as skin breaking, scratching, cracking and other mechanical damage to the appearance of radish, so that the radish will strengthen its own respiratory effect for the purpose of self-protection, and the strong respiratory effect will inevitably increase the loss of water and nutrient consumption inside the radish, and over time, this will also cause the problem of hollowing out of the radish due to excessive loss of water and nutrients.
The solution to this problem is relatively simple: on the one hand, it can be harvested in time after the radish is ripe, on the other hand, it is necessary to pay attention to being careful when harvesting radish, try to protect the integrity of the fleshy root under the radish, and try not to cause any mechanical or artificial wounds on the surface of the radish!
Seventh, the hollow radish is related to the storage environment
Generally speaking, radish needs to be placed in a cool, moist environment after harvesting, but if we put the harvested radish in a relatively high temperature and dry air environment, then the radish will accelerate the respiration effect due to high temperature drying during storage, resulting in the gradual loss of water and nutrients in the fleshy roots of radish, and over time, the radish will inevitably have a hollow problem.
This solution is also relatively simple, we take the radish back or buy back, try to put it in a low temperature humid environment of 0-3 degrees, air humidity of 90-95% for storage, when the temperature of radish storage is higher than 5 degrees or air humidity below 90%, then the radish is easy to be hollowed out because of dehydration and continuous consumption of nutrients in the body.
For our farmer friends, we can put the harvested radish in a cool and ventilated place and bury it in moist sand!
