What to Do When a Pear Tree Has Many Flowers but Few Fruits? Learn How to Improve the Fruit-Setting Rate

The pear is one of the most common fruits in our country. It is sweet and delicious, crisp and juicy, and is also one of the best fruits for clearing heat and detoxifying. However, pear trees also encounter many problems during cultivation, among which having many flowers but few fruits is relatively common. So why do pear trees produce many flowers but few fruits? How can this situation be solved? Let's take a look below.

1. Causes

A pear tree having many flowers but few fruits may be caused by excessive nitrogen fertilizer. Applying too much nitrogen fertilizer will cause the pear tree to grow excessively, producing only flowers and no fruit. Moreover, some fruit growers pour incompletely decomposed farmyard manure into the orchard, which can also cause the fruit tree to grow excessively and produce only flowers without fruit. Excessive moisture leads to pollination failure. When the pear tree is in its flowering period and encounters rainy weather while orchard drainage is poor, the tree will develop poorly, affecting pollination between male and female flowers and reducing the fruit-setting rate.

2. Prevention and Control Measures

First, you need to understand the reasons why the pear tree has many flowers but few fruits, and then, after understanding them, treat the cause accordingly. The amount of nitrogen fertilizer applied should be well controlled, and fertilization should be reasonable, and it should be sprayed together with Zhikong Cuihuawang. This can replace other hormones used to eliminate pesticides on fruit shoots and can also reduce the manual burden of girdling. The growth rate of branches and shoots should be well controlled. If they grow too long, they should be pruned appropriately to keep the flowers on the tree balanced, transfer the nutrients of the flowers to the fruit, and improve the quality of the flesh. Pay attention to observing the moisture conditions in the orchard, control them well and pay attention to drainage. Methods such as bees can be used to increase the pollination rate.

3. Methods to Improve the Fruit-Setting Rate

(1) Ensure the nutrition of the entire tree. One month after harvest, base fertilizer and organic fertilizer can be applied to promote soil nutrition and maintain the growth and development of the pear tree roots.

(2) After ensuring the nutrition of the pear tree, ensure the pollination rate among pear flowers. Because the success rate of natural pollination is relatively low, artificial pollination can be used. For example, during the flowering period, a nutrient solution containing substances such as zinc can be sprayed to promote pollination and fertilization. A writing brush or similar tool can also be used to dip a little pollen onto the flowers for pollination, but this method is relatively risky because carelessness can damage the stigma and produce the opposite effect.

(3) Pay attention to flower thinning and fruit thinning, and keep the flowers on both sides of the pear tree. Leave one fruit about 20 cm apart, remove the small ones and keep the large ones, remove the denser ones and the upper and lower ones, and promptly deal with deformed fruits and diseased fruits. Also pay attention to weather conditions, drain water promptly in rainy weather, and apply more foliar fertilizer.

This situation of many flowers but few fruits is relatively common. It affects the yield of pear trees and therefore directly affects the interests of fruit growers. Therefore, management must be correct. Artificial pollination is a very important step in cultivation. Increase the pollination rate and fruit-setting rate, pay attention to orchard drainage, and avoid the occurrence of this situation.
