How can fruit trees effectively improve their fruit-setting rate?

For growers, the fruit-setting rate is closely tied to the economic returns of fruit tree cultivation. If the fruit-setting rate of fruit trees is low, it will seriously affect the income of fruit farmers. So how can the fruit-setting rate of fruit trees be improved in production? Let's take a look at the detailed introduction below.

1. Spraying boron during the flowering period

According to production practice, spraying boron fertilizer during the flowering period of fruit trees can effectively improve the fruit-setting rate of fruit trees. Generally, spraying a low-concentration borax solution once at the beginning of the full flowering period will not only improve the fruit-setting rate, but also reduce flower drop.

2. Artificial pollination

Some fruit trees, due to varietal reasons, have poor self-pollination ability and need external help to complete pollination. In this case, artificial pollination is needed. First, when the main cultivated variety blooms, collect the pollen and place it in a greenhouse environment, which should not exceed 30, then dry it in the sun for one day on a sunny day, taking care not to expose it to strong sunlight. The commonly used pollination method is the point pollination method: mix the pollen and talcum powder at a ratio of 1:3, use a brush or cotton swab to dip the pollen, and touch it directly to the pistil of the female flower to complete pollination.

3. Flower thinning and fruit thinning

Flower thinning and fruit thinning adjusts fruit trees with relatively dense flowers and fruits so that their load is appropriate. For example, for fruit trees with more flowers and fruits, overly dense clustered flowering branches should be thinned, and branches with more fruit set should also be thinned more, so as to avoid a heavy burden on the fruit tree and insufficient nutrient supply, which is unfavorable to the development of yield and quality. Generally, each fruiting branch only needs to retain 1-2 strong fruits, and the remaining fruits should be thinned in time to ensure that the fruits have sufficient nutrients for growth.

4. Spraying fertilizer after flowering

After flowering and fruiting, fruit trees consume a large amount of nutrients, and the growth of new shoots, roots and leaves also requires a large amount of nutrients. At this time, if the planted nutrients are insufficient, it will cause physiological fruit drop, so fertilizer should be applied in time to supplement nutrients. Generally, spraying a low-concentration urea solution once 10 days after flowering has a clear effect on promoting the growth of branches and leaves and reducing physiological fruit drop.
