Causes of peach fruit cracking and preventive measures

Fruit cracking is a common phenomenon when growing peaches, which often occurs in the peach fruit expansion or ripening period, but if it is a large area of fruit cracking, it not only reduces the yield of peaches, but also affects the appearance of peaches and economic benefits. So what is the reason for peach cracking? How to prevent it? Let's take a look at the pro-farm network.

1. Variety characteristics

The fruit of some peach varieties is easy to crack, such as crisp pulp, round fruit, early and medium-ripe fruit.

Preventive measures: selecting varieties with compact fleshy fruit, oblong shape, late ripening or late ripening can reduce the possibility of fruit cracking to some extent.

2. Environmental factors

During the kernel growing period of peaches, cloudy and rainy weather is often encountered, which is easy to cause fruit cracking; planting in the soil with heavy stickiness, high groundwater level and poor drainage is also easy to cause fruit cracking; sudden precipitation after a long drought will also lead to fruit cracking; excessive pruning will also cause fruit cracking; heavy tree damage will also lead to fruit cracking, poor soil and other reasons will lead to peach fruit cracking.

Preventive measures: good drainage measures should be taken in case of overcast and rainy weather; soil with deep and loose soil layer, high groundwater level and good drainage should be selected when planting; timely watering to keep moisture in time in times of drought; pruning should be based on the growth state of the tree, the excess branches and leaves should be trimmed off to maintain good plant permeability; strengthen management to prevent diseases and insect pests from damaging the tree, apply sufficient fertilizer, and change the impoverishment of the soil.

3. Improper management of fertilizer and water.

The application of nitrogen fertilizer in peach seedlings and growing period can make it grow rapidly, but nitrogen fertilizer is not omnipotent and can not be applied all the time. Excessive application of nitrogen fertilizer makes the plant grow excessively and is easy to cause fruit cracking. In addition, the single application of nitrogen fertilizer will lead to the loss of calcium and other fertility, peach trees are very sensitive to calcium, calcium deficiency will not only lead to fruit cracking, but also lead to peach fruit softening and decay.

Preventive measures: apply fertilizer scientifically, pay attention to the proportion of other fertility, and suggest using completely mature organic fertilizer or compound fertilizer, so as to take care of every kind of fertility. if fruit cracking still occurs, calcium fertilizer should be applied in time.

4. Overuse of dilatant

Now many fruit growers in order to ensure yield, in the fruit expansion period will more or less hit a little expansion agent, so the fruit is big and beautiful, this is also human nature, the use of appropriate expansion agent, will not cause harm to peaches. However, the use of swelling agent is excessive or inappropriate, resulting in the rapid expansion of pulp cells in a short time, and finally break the pericarp and crack the fruit.

Preventive measures: the best thing is not to use the expansion agent, even if you use it, you should pay attention to the method and dose, never act in haste, step by step.

The above are the causes and preventive measures of peach fruit cracking brought by the pro-agricultural network. This is the end of the introduction of peach fruit cracking. When planting peaches, we should also pay attention to the prevention and control of diseases and insect pests. Many diseases and insect pests will also lead to the problems of fruit cracking, deformed fruit and rotten fruit. More agricultural knowledge, please pay attention to the pro-agricultural network.
