What if the pear tree has more flowers and less fruit?

Pear is one of the most common fruits in China, it is sweet and delicious, crisp and juicy, and it is also one of the best fruits for heat-clearing and detoxification. However, pear trees will also encounter many problems in the process of planting, among which pear trees with more flowers and less fruits are more common, so why do pear trees produce more flowers and less fruits? How can this situation be solved? Let's take a look at it.

1. The cause

Pear trees with more flowers and less fruit may be due to too much nitrogen fertilizer, too much nitrogen fertilizer will lead to false growth of pear trees, only blossom but not fruit. And some fruit grower friends will not fully mature farm manure into the orchard, will also lead to the false growth of fruit trees only blossom but not bear fruit. Too much water leads to the failure of pollination and poor drainage in the orchard in overcast and rainy weather during the flowering period of pear trees, which will make the tree underdevelop, affect the pollination between male and female flowers, and reduce the fruit setting rate.

2. prevention and control measures

First of all, it is necessary to understand the reasons why pear trees have more flowers and less fruit, and then prescribe the right medicine according to the reasons. In order to control the amount of nitrogen fertilizer, we should apply fertilizer reasonably and spray it together with intelligent control to promote flower king. This can replace other hormones to eliminate pesticides on fruit tips, and can also reduce the artificial burden of ring peeling. To control the growth rate of branches, if it grows too long, it should be pruned properly, keep the flowers in balance, transfer the nutrition of flowers to the fruit, and improve the quality of pulp. We should pay attention to observe the water situation in the garden, control and pay attention to drainage, and bees and other means can be used to improve the pollination rate.

3. Methods to improve fruit setting rate.

The main results are as follows: (1) to ensure the nutrition of the whole tree, basal fertilizer and organic fertilizer can be applied one month after harvest to promote soil nutrition and maintain the growth and development of pear roots.

(2) after ensuring the nutrition of pear trees, it is necessary to ensure the pollination rate between pear flowers, because the success rate of natural pollination is low, so artificial pollination can be used. For example, you can spray some nutrient solution with zinc and other substances during the flowering period, which can promote pollination and fertilization. You can also use a brush to pollinate flowers with a little pollen, but this method is dangerous because it will destroy the stigma and be counterproductive if you are not careful.

(3) pay attention to thinning flowers and fruits, and keep the flowers on both sides of the pear tree. Leave a fruit about 20 centimeters, remove the small ones and leave the larger, denser, upper and lower ones, and deal with the deformed fruit and diseased fruit in time. Also pay attention to the weather conditions, rainy weather timely drainage, more foliar fertilizer.

This kind of situation with more flowers and less fruit is relatively common, which will affect the yield of pear trees and directly affect the interests of fruit farmers. Therefore, it must be managed correctly, artificial pollination is a very important step in planting, improve the pollination rate and fruit setting rate, pay attention to the drainage in the garden to avoid the occurrence of this situation.
