How to prevent peaches from falling fruit

Friends who grow peaches at home do not know if they have found that peach trees often blossom a lot and bear a lot of fruit in the end, but soon after the fruit, many small, green peaches fall from the ground, and only a small number of them ripen in the end. This is not very satisfactory, so this is why, how can we solve this problem and improve the fruit-setting rate? Please see below.

First, the cause of fruit drop

First, there are too many flowers, no sparse flowers, so there are many fruits, but the tree is not nutritious enough, so it does not supply so much fruit, so it has to fall. Or the growth of the tree itself is relatively weak, and lack of nutrition, there is no supplement of fertilizer, it will cause fruit drop. There is also the peach tree itself will have the physiological cause of fruit drop. In addition, it is the loss of pollen during the flowering period, poor pollination and fertilization, resulting in hypoplasia and abnormal shedding. Finally, with the partial application of nitrogen fertilizer, the branches will grow, and the fruit nutrition will fall off after being competed for nutrition.

II. Preventive measures

1. Thinning flowers and fruits

It can be carried out when flowering is about 60%. In general, flowers grow in clusters, leaving weak and strong, and five or six flowers in clusters and two or three flowers. All underdeveloped flowers will fall by gently shaking the branch. for the flowers on the weak branches, the flowers in the same node should be removed, leaving 40% of the flowers, and about 65% for the flowers on the strong branches. Two months after the fruit, the fruit began to be fixed, leaving fruit at the relative node, removing part of the same side too much, and leaving more fruit on the strong branches and less on the thin branches. As a result, the branches are cut off, just like the drooping branches.

two。 Guarantee nutrition

In addition to thinning flowers and fruits, it is also necessary to trim off dead branches, overlapping branches, only long branches, drooping branches, and dense internal branches. Pick some old leaves to reduce nutrient consumption. Fertilization in the spring full application of base fertilizer, topdressing can not be less, the whole fruiting period should be topdressing three times, not partial application of nitrogen fertilizer, should apply compound fertilizer. Water supply should be carried out three days after topdressing, depending on the soil condition, watering many times, but the flowering period should be controlled.

3. Artificial pollination and spraying fruit protectant

Can be artificial pollination, pollination before the rainy season, after pollination can be re-pollination in case of rain, pay attention to the weather, try to complete pollination and fertilization process before rain, artificial pollination can ensure the success rate of pollination and fertilization. Avoid the phenomenon of hypoplasia. Make sure there are more results, and there will be more fruit. In addition, Guotiling can be sprayed after the result.

Peaches fall a lot of fruit, abnormal, we should first find the cause, according to the root cause of the problem to improve the problem of fruit drop, another is to know the cause, we will know how to prevent it in the future. The problem of peach fruit drop can be improved through the above measures. Thank you for reading. I hope it will be helpful to you.
