What are the latest methods to improve the fruit-setting rate of fruit trees?

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.

1. Spraying boron during the flowering period

Production practice shows that spraying boron fertilizer during the flowering period of fruit trees can effectively improve the fruit-setting rate. Generally, spraying a low-concentration borax solution once at the beginning of full bloom 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 such cases, artificial pollination is required. First, when the main cultivated varieties bloom, collect 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 direct scorching sun. The commonly used pollination method is the point pollination method: mix 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 stigma of the female flower to complete pollination.

3. Flower and fruit thinning

Flower and fruit thinning is the adjustment of fruit trees with relatively dense flower and fruit growth so that their load is appropriate. For example, for fruit trees with many flowers and fruits, overly dense clusters of flowering branches should be thinned out, and branches with many set fruits should also be thinned more to avoid placing too heavy a burden on the fruit tree, causing insufficient nutrient supply and hindering 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.
