How to prevent the chestnut from being empty?

How to prevent the chestnut from being empty? What methods can be used to guide the empty bud of Chinese chestnut, also known as empty canopy, empty shell, fruit growers are called "dumb chestnuts". The empty bract rate of Chinese chestnut is generally about 15%, the high 80%, and some almost the whole plant empty bud. Therefore, preventing empty buds is the key to improve the yield and quality of Chinese chestnut. The seed setting rate of cross-pollination of Chinese chestnut with reasonable pollination is high, and self-pollination is often not easy to bear fruit. Therefore, when planting, we should select the excellent varieties with high seed setting rate, and pay attention to the selection of pollination trees. There are many varieties of Chinese chestnut in different places, and the pollination combinations are different. For example, the main variety is Gannong 77Muo01, and its pollination combinations are Gannong 77-02 and Gannong 77Muo04 respectively. The number of pollination trees should account for about 1 / 3 of the total number of trees. The practice shows that the reasonable selection of pollination combination can greatly increase the seed setting rate and the yield of Chinese chestnut. Chestnut trees with proper thinning of male flowers are monoecious, with male inflorescences blooming first and female inflorescences blooming later. When the male inflorescence is 2cm long, 90% of the male flowers are removed, which not only does not affect the normal pollination of the tree, but also has beautiful leaves, high seed setting rate, increased single fruit weight, and can mature 7-10 days earlier, so that it can be harvested and listed early. The proper removal of male flowers from Chinese chestnut is indeed a measure to increase production and income, especially for young trees. The application of boron fertilizer in Chinese chestnut is very sensitive to boron, especially in boron-deficient soil, which can effectively reduce the empty bract rate and increase the yield per plant. The specific application methods are as follows: first, boron is applied in the budding stage, combined with budding fertilizer in early spring, borax is applied to the soil, generally, 100 grams of borax is applied to each plant, and more boron can be applied in the soil with boron deficiency. Second, boron spraying at flowering stage, 100 grams of borax per 15 ha and 50 kg of water are sprayed evenly on female flowers, and the concentration of boron spraying can be increased appropriately for those with high empty bract rate. After applying boron and spraying boron, the empty bract rate of Chinese chestnut can be reduced by 20% to 30%, and the yield can be increased by 3% to 4 times.
