The causes and preventive measures of the latest peach fruit cracking

Fruit cracking is a common phenomenon when planting peaches, which mostly occurs in the expansion or maturity period of peach fruits. However, if it is large-scale fruit cracking, it not only reduces the yield of peaches, but also affects the appearance of peaches and affects economic benefits. So what is the cause of peach cracking? How can we prevent it? Let's take a look at the pro-farming network together.

1. Variety characteristics

Some peach varieties bear fruit that is easy to crack, such as crispy fruit, round fruit, early and medium ripe fruit.

Preventive measures: selecting fruit with tight flesh, oblong shape, late maturity or late maturity varieties for planting can reduce the possibility of cracking fruit to a certain extent.

2. Environmental factors

During the growth period of peach stone, rainy weather is often encountered, which is easy to cause fruit cracking; planting on soil with heavy viscosity, 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: drainage measures shall be taken in rainy weather; soil with deep loose soil layer, high groundwater level and good drainage shall be selected for planting; timely watering shall be carried out to maintain water content in drought; pruning shall be carried out according to the growth state of tree body, and redundant branches and leaves shall be pruned off to maintain good plant permeability; management shall be strengthened to prevent diseases and insect pests from damaging tree body, and sufficient base fertilizer shall be applied to change soil sterility.

3. Improper management of fertilizer and water

Application of nitrogen fertilizer in seedling and growth stage of peach tree can make it grow rapidly, but nitrogen fertilizer is not omnipotent, can not be applied all the time, excessive nitrogen fertilizer application, make plants grow excessively, easy to cause fruit cracking. In addition, single application of nitrogen fertilizer will lead to calcium and other fertility deficiency. Peach trees are extremely sensitive to calcium. Calcium deficiency will not only cause fruit cracking, but also cause peach fruits to become soft and rotten.

Preventive measures: fertilization should be scientifically matched, attention should be paid to the application ratio of other fertility, it is recommended to apply completely decomposed organic fertilizer or compound fertilizer, so that each fertility is taken care of, if there is still cracking phenomenon, it is necessary to timely apply calcium fertilizer.

4. Excessive use of swelling agent

Nowadays, in order to ensure the yield, many fruit growers will use a little expansion agent more or less during the fruit expansion period, so that the fruit is big and beautiful, which is also human nature. The proper use of expansion agent will not cause harm to peaches. However, excessive or improper use of swelling agent resulted in rapid swelling of pulp cells in a short time, and finally broke the pericarp and caused fruit cracking.

Preventive measures: the best is not to use swelling agent, even if the use should pay attention to the method and dosage, do not act too hastily, step by step.

The above are the reasons and preventive measures for peach cracking brought by the pro-agricultural network. The peach cracking is introduced here. When planting peaches, attention should also be paid to pest control. Many diseases and insect pests will also lead to cracking, abnormal fruit and rotten fruit problems.
