Causes of cracking of mango and its control measures

In mango production, fruit cracking often occurs, generally in the later stage of fruit expansion, the originally well-grown fruit will crack because it grows too fast, which seriously affects the quality, and some fruits will crack in the young fruit. So what is the cause of mango cracking? Let's get to know it.

1. Rapid change of moisture

In the later stage of fruit growth, if the water content of the fruit is watered and sugar is accumulated in the case of high temperature and drought, and if it rains suddenly or is watered too much, the water in the orchard is out of balance, which will lead to the root system absorbing a large amount of water, resulting in the rapid expansion of the fruit. if the growth rate of the pericarp can not keep up with the rate of water absorption by the pulp, it will cause the pericarp to expand and crack.

Prevention and control methods: pay attention to the uniform supply of water during fruit growth, especially in the rainstorm season, drainage measures should be taken, timely watering should be taken during drought, but attention should be paid to watering, and at the same time, water should be sprayed on the crown to increase humidity and reduce temperature. promote pericarp growth to avoid cracking.

2. Improper use of hormones

The changes of plant endogenous hormones will affect the growth rate of pericarp and pulp, and the loss of balance between them will lead to fruit cracking. in order to promote fruit expansion, many fruit growers often use expansion agents, and improper use will also cause fruit cracking. After the use of expansion agent, the cell division is exuberant, and the pulp growth rate exceeds the pericarp growth rate, causing fruit cracking.

Prevention and control measures: pay attention to the application of growth regulators, select suitable varieties, weather and concentration, do not use blindly, spray 1-2 times of anti-cracking age in the expansion period, ease fruit growth rate, increase pericarp toughness and reduce fruit cracking.

3. Nutritional imbalance

The fruit needs to absorb a variety of nutrient elements in the process of growth, and if the fruit is deficient in calcium, it will cause fruit cracking, and there is resistance and coordination among the nutrient elements. If one element absorbs the amount of fruit, it will inhibit the absorption of other elements, which will also cause fruit cracking. Many fruit growers apply calcium fertilizer during the fruit expansion period, but the fruit will still crack, which is caused by the nutritional imbalance caused by the resistance of elements. Studies have shown that nitrogen will be resistant to calcium and magnesium ions, and excessive nitrogen will affect the absorption of calcium and magnesium ions by plants.

Prevention and control measures: attention should be paid to balanced nutrition when applying fertilizer to prevent the resistance between elements from leading to nutritional imbalance. Boron fertilizer can be applied in the later stage of fruit, which can promote the absorption of calcium and reduce fruit cracking.
