How to reduce the empty bract rate of Castanea mollissima

Chinese chestnut is one of the common dried fruits. It tastes delicious. High nutritional value, deeply loved by people, but in the process of planting Chinese chestnut, the reason of empty bud seriously affected the yield of Chinese chestnut. Is there any way to reduce the empty bract rate of Chinese chestnut? The following editor introduces the methods to reduce the empty bract rate of Chinese chestnut for your reference.

1. Select superior varieties

There is an inevitable relationship between the occurrence of empty buds and seed selection of Castanea mollissima. If the varieties with poor or weak fruiting ability are selected, the yield of Chinese chestnut will be seriously reduced. We should choose high-quality varieties, pay attention to the pursuit of variety quality, select businessmen with good reputation and positive channels, and test and investigate the fruit setting rate of chestnut varieties. Once they are unqualified, they should be abandoned in time, so as to avoid a large number of empty buds after planting, affecting the yield of Chinese chestnut. Scientific selection is an effective way to avoid the occurrence of empty buds of Chinese chestnut, and the selection of high-yield and high-quality varieties is an important way to achieve high yield.

2. Do a good job in soil and fertilizer management

When planting, we should carry out strict management of the soil, regularly turn the soil deeply, reasonably close planting, grasp the spacing between planting rows, improve deep ploughing, provide sufficient nutrients for the soil, and maintain good permeability. Hay leaves can also be selected as mulch and sufficient farm manure will be applied to create a good growth environment for the growth of Chinese chestnut. Covering the moving weeds on the tree plate helps to maintain moisture and increase the content of organic matter in the soil. In order to keep the weeds from being blown away, a thin layer of soil should be covered with weeds. In order to increase the yield, intercropping can be used to plant other crops in Chinese chestnut, such as sweet potato and peanut, which can improve the soil effect, enhance the soil fertility and increase the fruit setting rate.

3. Carry out boron application.

Boron is a key element in the growth of Chinese chestnut, which determines the yield and empty bud phenomenon of Chinese chestnut. It should be analyzed according to the growth situation and soil conditions of Chinese chestnut, and quantitative boron should be applied scientifically to promote the growth and development of Chinese chestnut and avoid the occurrence of empty bud phenomenon. The time of boron application should be in April in spring or July in the rainy season, and its effect is long-lasting. Boron spraying chooses foliar fertilizer, generally in the middle and first ten days of 5-6, three times a month, a certain effect can be achieved after spraying for one month, and the empty bud phenomenon has been improved.

4. strengthen the prevention and control of diseases and insect pests

In the process of chestnut growth, flowering and fruit setting, the occurrence of chestnut diseases and insect pests is also one of the important reasons leading to the empty bud of Castanea mollissima. If the selection of varieties is poor or the disease resistance of varieties is weak, the diseases and insect pests will occur frequently, which hinders the growth of chestnut trees and can not blossom and bear fruit normally, thus reducing the yield. Therefore, before planting, we should choose varieties with strong disease resistance, strengthen the prevention and control of diseases and insect pests when planting, and treat them in time once diseases and insect pests are found.
