The reason for the low fruit setting rate of plums

For plum farmers, if they want to improve their economic returns, the most important thing is to improve the fruit setting rate. However, many farmers have extremely low fruit setting rate in their own plum orchards. What is the reason for this? Let's take a look at it together with Xiaobian.

1. Improper selection of varieties

Greenhouse cultivation of plants its growth environment and the outside world has obvious differences, which will lead to good varieties of open field cultivation is not cultivated in the greenhouse, but some farmers directly in the open field cultivation varieties covered with greenhouses, into greenhouse cultivation varieties, has reached the goal of early maturity, early listing. In fact, this is a wrong way to do well, some open field cultivation varieties, because winter cold demand is large, self-pollination ability is poor, nutritional growth exuberant, and in greenhouse cultivation will appear nutritional growth or excessive phenomenon, resulting in more flowers and fewer fruits. For this problem, we should choose the right variety according to our own cultivation mode.

2. Climatic reasons

Because the temperature in spring is extremely unstable, the temperature fluctuates, and it is easy to appear late spring cold phenomenon. Such climate environment will have a great impact on pear flowering and pollination, which is likely to lead to pollination failure. There is no artificial way to change the climate conditions, but it can be solved through greenhouse cultivation, and at this time it is necessary to pay attention to the selection of varieties.

3. Fewer pollen trees

Many people forget to increase plum variety when planting plums, so that when pollination season comes, the plants do not have enough pollen to complete pollination. Thus, even if the fruit tree has a large number of flowers, but there is no fruit tree to provide pollen, its fruit set rate will not be improved. Therefore, pollinating trees must be planted in a reasonable proportion in the cultivation process to complete pollination normally and improve the fruit setting rate.

4. Unreasonable pruning

Pruning plums is to increase the ventilation and permeability of fruit trees and improve the fruit setting rate. However, if the pruning is excessive, the number of branches will be too small, so that the number of fruit branches will naturally be small, which will directly affect the yield. However, if the number of branches left is large, the nutrition is too scattered, the ventilation is poor, the inner bore twigs are easy to die, the fruit position will move outward, and the yield will be reduced. Therefore, reasonable pruning and keeping proper branch quantity are important guarantee of high yield, stable yield and high quality.

The above is the introduction of the reasons for the low fruit setting rate of plums. I hope it can help you. If you want to know more about it, please pay attention to us.
