Prevention and control of pear cracking

Many varieties of pears are prone to crack in the process of planting, which not only affects the beauty but also the taste, so it is difficult to sell. There are many reasons for pear cracking, how to prevent and cure it?

First, the cause of pear cracking

The main results are as follows: 1. Rain Water is too much, the pulp tissue is overdeveloped, and the epidermal cells of the pericarp develop slowly, which leads to the cracking of the cuticle of the epidermis.

2. the tissue of the black spot disease stopped growing and sunken, causing the pear fruit to crack.

3. Excessive nitrogen fertilizer, excessive growth of branches and leaves, thin epidermis and poor strength of fruit epidermis, and rapid development of pulp, resulting in epidermis rupture.

4. Lack of potassium, boron and calcium fertilizer can also cause pear fruit cracking.

What is the prevention and cure of pear cracking?

1. Strengthen irrigation in the early stage and pay attention to drainage in the later stage, so that the water supply is balanced, the internal and external growth of the pulp is coordinated, and small water is used to irrigate slowly during drought irrigation.

2. Clearing ditches and draining water in time after rainfall to improve soil permeability, appropriate summer pruning to remove overgrown branches and excessive closure of branches, and improve ventilation and light transmission conditions of pear orchards.

3. Timely ploughing and weeding, keeping loose soil in the rhizosphere of tree disk, increasing soil water content, enhancing soil air permeability, creating a good growth environment for root system, tree disk mulching, reducing soil moisture evaporation and ensuring a balanced supply of soil moisture and nutrients.

4. Balanced fertilization, do not apply too much nitrogen fertilizer, timely and appropriate amount of potassium, boron, calcium fertilizer, generally 5-6-year-old pear tree about 100g of potassium sulfate or plant ash 2-3kg, applied in the 30cm outside the root.

5. Strengthen the prevention and control of black spot and control the harm of black spot to pear fruit. Bagging can also reduce the damage of black spot to pear fruit, thus reducing the rate of fruit cracking.

Do a good job in orchard management, strengthen tree potential, and reasonably control irrigation.
