The latest ways to improve the fruit setting rate of fruit trees

For growers, the fruit setting rate is closely related to the economic benefits of fruit trees. if the fruit setting rate of fruit trees is low, it will seriously affect the income of fruit farmers. So how to improve the fruit setting rate of fruit trees in production? Let's take a look at the detailed introduction.

1. Boron spraying at flowering stage

According to the production practice, spraying boron fertilizer at the flowering stage can effectively improve the fruit setting rate of fruit trees. Generally, spraying a low concentration borax solution at the early flowering stage will not only increase the fruit setting rate, but also reduce the phenomenon of flower drop.

2. Artificial pollination

Because of the variety, some fruit trees have poor self-pollination ability and need more outside help to complete pollination. For this situation, artificial pollination is needed. First of all, when the main varieties bloom, collect pollen and place it in the greenhouse environment, not more than 30 pairs, and then dry in a sunny day, pay attention not to exposure. The common pollination method is point-in-time pollination, in which the pollen and talcum powder are mixed at 1:3, and the pollen is dipped with a brush or cotton swab to directly touch the stamens of the female flowers to complete pollination.

3. Thinning flowers and fruits

Flower and fruit thinning is to adjust the fruit trees with dense flower and fruit growth to make their load appropriate, for example, the fruit trees with more flowers and fruits should be thinned, and the branches with more fruit should be thinned, so as to avoid the heavy burden of fruit trees and insufficient nutrition supply. it is disadvantageous to the development of yield and quality. In general, each fruiting branch needs to leave 1-2 strong fruits, and the rest should be thinned out in time to ensure that the fruit has sufficient nutrients to grow.

4. Spraying fertilizer after flowering

Fruit trees will consume a lot of nutrients after flowering and fruiting, and the growth of new shoots, roots and leaves also need a lot of nutrients, at this time, if the planting nutrition is insufficient, it will cause physiological fruit drop, so it is necessary to apply fertilizer in time to replenish nutrients. Generally, spraying low concentration urea solution 10 days after anthesis has obvious effect on promoting the growth of branches and leaves and reducing physiological fruit drop.

The above is the introduction of how to improve the fruit setting rate of fruit trees. I hope it can help you. If you want to know more about it, please follow us.
