How to improve the fruit setting rate of plums

Plum is a kind of fruit, which is well-known in our country. It is a favorite of many people, and now the planting area of plum trees in China is very extensive. However, many people will find that the fruit setting rate is very low when planting. Therefore, how to improve the fruit setting rate has become a matter that many fruit growers need to pay attention to. Then the editor will introduce several ways to improve the fruit setting rate of plums. Let's have a look!

1. Planting and pollination

When we plant plum trees, we should pay attention to the reasonable configuration of the tree specifications in the orchard. It is necessary to ensure that there are a certain number of pollination trees in the orchard, especially there is a large proportion of low seed setting rate or less pollen in the orchard. The number of pollination trees should be kept at about 30%. Then in the flowering period, bees can be pollinated properly, and honeybees can be used to pollinate plum trees. In addition, artificial pollination should be carried out appropriately, using brushes or brushes to transfer pollinated pollen into the flowers of varieties to improve the pollination rate.

2. Temperature control

Plum trees are sensitive to changes in temperature. When planting, we should pay attention to the site selection work, not in low-lying, water-prone places. Avoid stagnant water, poor ventilation lead to insufficient temperature, affecting the growth of plums. Then in the plum tree flowering period, we should pay attention to observe the weather changes, when the temperature changes greatly, we should make preparations. Can smoke properly to prevent advection frost, reasonable watering, in the occurrence of frost in the evening appropriate spray on the tree, reduce frost phenomenon, improve the fruit setting rate of plum trees.

3. Shaping and pruning

The shape of the plum tree is relatively large, in the planting process, we should pay attention to control the shape of the tree, do a good job of shaping and pruning. For some overgrown trees, it is necessary to cut off the branches that are too dense and too long, do a good job of sprouting, and expand the angle of the crown. Then the pruning method should be adjusted reasonably according to the age and potential of the tree. Reasonable pruning can not only concentrate nutrition on flowers and fruits, but also improve the permeability of fruit trees and enhance the growth ability of plum trees. Then the weak trees can be cut lightly or not to increase their nutrition and fruit setting rate.

4. Pest control

There are many diseases and insect pests in plum trees, among which many diseases and insect pests will harm the flowers and fruits of plum trees. It leads to all kinds of bad phenomena, such as falling flowers and fruits, rotten fruits and so on. Therefore, we should also focus on the prevention and control of diseases and insect pests of plum trees and enhance the disease resistance of geese. In the full bloom, we should pay attention to spraying germicidal grease and other agents, do a good job of disinfection. Then it is necessary to do a good job in clearing the garden in winter, remove the sick and disabled bodies and weeds in the garden, dig deep into the soil, and destroy the overwintering places of germs. After the disease, corresponding measures should be taken in time to ensure the healthy growth of plum trees and increase the yield.

The above is a brief introduction to how to improve the fruit setting rate of plums. The fruit setting rate of plum trees is directly related to its yield, so we must pay more attention to it. That's all for today's introduction. This article is for reference only. I hope it can help you all.
