How to Improve Low Fruit Set in Plum Trees? Practical Methods Shared
The plum is a fruit with fairly high recognition in our country. It is loved by many people, and plum trees are now planted across a very wide area in our country. However, many people find when planting them that their fruit set rate is very low. Therefore, how to improve the fruit set rate has become something many fruit growers need to pay special attention to. So the editor will introduce several methods for improving the fruit set rate of plum trees. Let's take a look!
1. Planting and Pollination
When planting plum trees, we should pay attention to reasonably configuring the tree specifications within the orchard. We must ensure there is a certain number of pollinator trees in the orchard, especially when the orchard contains a relatively large proportion of trees with low fruit set or little pollen. The number of pollinator trees should be kept at around 30 percent. Then, during the flowering period, bees can be appropriately released for pollination, using bees to carry out pollination work for the plum trees. Artificial pollination should also be carried out appropriately, using a brush or a paintbrush to transfer pollinating pollen onto the flowers of the varieties, thereby improving the pollination rate.
2. Temperature Control
Plum trees are relatively sensitive to changes in temperature. When planting, we should pay attention to doing a good job of site selection, and it is not advisable to choose low-lying places that easily accumulate water. This avoids water accumulation and poor ventilation leading to insufficient temperature, which affects the growth of the plums. Then, during the flowering period of the plum trees, pay attention to observing weather changes. When the temperature changes greatly, preparation work should be done well. Smoke can be appropriately used to prevent advection frost, watering should be reasonable, and when frost occurs, the trees should be appropriately sprayed with water at night to reduce the frost phenomenon and improve the fruit set rate of the plum trees.
3. Shaping and Pruning
The tree form of plum trees is relatively large. During the planting process, we should pay attention to controlling the tree form well and do a good job of shaping and pruning. For some trees growing too vigorously, the overly dense and overly long branches should be cut off, bud removal should be done well, and the angle of the canopy should be expanded. Then, the pruning method should be reasonably adjusted according to tree age and tree vigor, etc. Reasonable pruning can not only concentrate nutrients on the flowers and fruits, but also improve the ventilation and light penetration within the fruit tree, enhancing the growth capacity of the plum tree. Then, for trees with weak growth, light pruning can be done or no pruning at all, increasing their nutrients and improving the fruit set rate.
4. Pest and Disease Control
There are many pests and diseases of plum trees, and many of them harm the flowers and fruits of plum trees. This leads to various adverse phenomena in plum trees such as flower and fruit drop and rotting fruit. Therefore, we should also focus on doing a good job of pest and disease control for plum trees and enhance the disease resistance of plum trees. During the full flowering period, pay attention to spraying agents such as sterilization lipids and do a good job of disinfection. Then in winter, do a good job of clearing the orchard, removing diseased and residual bodies, weeds, etc. in the orchard, and deeply plow the soil to destroy the overwintering sites of pathogens. After disease occurs, corresponding measures should be taken promptly to ensure the healthy growth of plum trees and increase yield.
The above is a brief introduction to how to improve the fruit set rate of plum trees. The fruit set rate of plum trees is directly related to their yield, so everyone must pay close attention. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
