The latest reasons for the low fruit setting rate of Chinese chestnut and the measures to improve it

Chinese chestnut is a traditional fruit in China, which is rich in nutrition and has the laudatory name of Oriental Pearl. It is distributed all over our country and has a wide artificial planting area. However, in artificial planting, there is often the phenomenon of low fruit setting rate, which seriously affects your output and the economic income of growers, so what is the reason for the low fruit setting rate of Chinese chestnut? If you deal with it, let's take a look at the pro-agricultural network.

1. The reason for the low fruit setting rate

The fruit setting rate of Chinese chestnut is mainly caused by lack of nutrients, poor pollination, weather, varieties and lack of trace elements. During the flowering period of Chinese chestnut, the branches and leaves of the plant grow with it, so it will lead to the phenomenon of grabbing nutrients, resulting in insufficient nutrients and low fruit setting rate. When Chinese chestnut is the same cross-pollinated tree, the opening time of male and female flowers is different, and there are often more male flowers and less female flowers, so the fruit setting rate is low. in addition, if there is overcast and rainy weather during pollination, it will lead to poor pollination or pollination failure, resulting in a decline in fruit setting rate. Therefore, in order to achieve high yield of chestnut, solving the fruit setting rate is the key, and these reasons are related to the fruit setting rate, so the management of these aspects should be strengthened in planting in order to achieve the fruit setting rate and achieve the goal of high yield.

2. Measures to improve fruit setting rate.

Strengthen fertilizer and water management: the lack of nutrients results in fruit setting rate, we should strengthen fertilizer and water management, the first thing to do is to apply adequate base fertilizer, dig a circular ditch around the planting after fruit harvest every year, and accumulate 100 kilograms of fertilizer in it, so that the tree can be restored as soon as possible and flower bud differentiation can be promoted in time. Then there is topdressing. Spring is the period of branch and leaf growth and flowering and fruiting, and the main time for low fruit setting rate is also at this time. At this time, we should choose quick-acting nitrogen fertilizer as the main choice. Each plant is supplied with about 1 kg of urea, which can make its branches and leaves luxuriant and blossom. In the later stage, in order to avoid the empty bud phenomenon, it is necessary to apply some boron fertilizer to increase the yield, about 0.1-0.25kg per plant, combined with foliar fertilizer spraying.

Reduce the number of male flowers: the number of male flowers of Chinese chestnut far exceeds that of female flowers, so the number of male flowers can be reduced appropriately in the flowering stage to avoid the consumption of plant nutrients and increase the number of female flowers accordingly. Generally, more male inflorescences are cut off from too many male flower branches or some fruit branches before flowering.

Artificial pollination: Chinese chestnut is a tree species with high seed setting rate of cross-pollination. According to the experimental results, the probability of co-pollination is only 20%, while the probability of cross-pollination is 90%. So when planting, plant some pollination varieties around the production varieties to improve the fruit setting rate. In addition to this method, the simplest method of pollination is to collect pollen, carry out artificial pollination, collect the male pollen of other plants, and apply it to the female flowers of other plants, with a 100% chance of pollination.

The above are the reasons for the low fruit setting rate of Chinese chestnut brought by the pro-agricultural network and the ways to improve the fruit-setting rate. I hope it can help you. If you want to know more, please pay attention to the pro-agricultural network.
