Causes of fruit cracking of jujube and its control measures

In the process of jujube growth, fruit cracking often occurs, which seriously affects the appearance and taste of jujube, and brings certain economic losses to fruit farmers. So what is the cause of fruit cracking in jujube trees? What should I do? Come and have a look with the editor.

First, the cause of fruit cracking

1. Too many Rain Water

In the mature period of jujube, due to excessive precipitation, the pulp will expand rapidly, and the growth rate of the peel can not keep up with the pulp expansion rate, which will break the pericarp directly.

2. Excessive application of chemical fertilizer

The application of chemical fertilizers in China has a history of more than 30 years. With the earlier application of chemical fertilizers, the varieties are also increasing, which will change the results of the soil, reduce the content of organic matter, cause soil consolidation, and lack of soluble calcium absorbed by jujube roots in the soil, resulting in fruit cracking.

3. Unbalanced nutrition

The growth of jujube is inseparable from trace elements, and minerals are closely related to fruit cracking of jujube. If jujube is lack of nitrogen, potassium, calcium, boron, magnesium and other elements, fruit cracking may occur, especially when soil calcium is deficient, fruit cracking is very easy to occur.

4. Lack of water and drought

Calcium deficiency is the main reason for fruit cracking of jujube. Most arid areas in northern China are lack of calcium, soil drought is not conducive to microbial activity, and calcium in soil can form soluble calcium absorbed by plants only through microbial metabolism, so it leads to plant fruit cracking.

II. Prevention and control measures

According to the analysis of the causes of fruit cracking, we can consider the soil moisture and calcium supplement, and take measures to prevent and control fruit cracking. First of all, the orchard can be covered with grass, covering a layer of 20 cm broken straw around the root system, and the appropriate time for grass mulching is from June to October, which can not only keep warm and moisturizing, but also conducive to the reproduction of microorganisms, increase soil soluble calcium and increase the content of organic matter. Watering the soil in time when the soil is dry and keeping the soil moist can effectively prevent fruit cracking. When the plant is lack of calcium, foliar fertilizer can be used to supplement the calcium needed by the plant and reduce the phenomenon of fruit cracking.
