The reason for the low fruit setting rate of the latest plum

For plum farmers, in order to improve their economic income, the most important thing is to improve the fruit setting rate, but many farmers' own plum orchard fruit setting rate is very low, what is the reason for this? Let's have a look with the editor.

1. Improper selection of varieties

The growing environment of the plants cultivated in the greenhouse is obviously different from that of the outside world, so that the varieties cultivated well in the open field are not cultivated in the greenhouse, but some farmers directly cover the greenhouse on the varieties cultivated in the open field and change them to the varieties cultivated in the greenhouse. has achieved the goal of early maturity and early listing. In fact, this is a mistake to do well, some varieties cultivated in open field, because overwintering requires a large amount of cold, poor ability of self-pollination, strong vegetative growth, while in greenhouse cultivation, there will be poor vegetative growth or excessive growth, resulting in more flowers and less fruit. 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 from high to low, and it is also prone to late spring cold, this climatic environment will have a great impact on pear flowering and pollination, which is very likely to lead to pollination failure. There is no way to change the climatic conditions, but they can be solved by greenhouse cultivation. At this time, we should pay attention to the selection of varieties.

3. Few pollen trees

When planting plums, many people forget to increase the variety diversity of plums, so that during the pollination season, the plants do not have enough pollen to pollinate. In this way, even if the fruit tree produces a large number of flowers, but there is no fruit tree to provide it with pollen, its fruit setting rate will not be improved. Therefore, in the process of cultivation, pollination trees must be planted in a reasonable proportion to make them 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, but if overbuilt, resulting in too few branches, so there will be fewer fruit branches, which will directly affect the yield. However, if the number of branches is large, the nutrition is too scattered, the ventilation and permeability is poor, and the inner branchlets are easy to die, the result will be that the part will move out and the yield will be reduced. Therefore, reasonable pruning and maintaining a suitable amount of branches is an important guarantee for 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 I can help you. If you want to know more about it, please follow us.
