What kind of medicine should peach crack fruit?

Peach cracking is a common disease during peach growth. If it is not prevented and controlled in time, the yield will decrease seriously. What medicine should be used for peach cracking?

1. What kind of medicine does peach crack fruit take?

Peaches usually crack without medicine. Because peach cracking is mostly physiological disease, generally in case of heavy rain for a long time, fruit trees absorb a lot of water, fruit rapid expansion will cause the peel to expand, at the same time calcium fertilizer, nitrogen fertilizer shortage, excessive use of expansion agent will make peach cracking fruit, so when cracking fruit, timely drainage measures should be done, scientific fertilization.

Second, what happened to the peach split fruit? How?

1. Variety characteristics

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

Solution: Choose fruit fleshy close, oval shape, late maturity or late maturity varieties planted, 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.

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

Solution: Fertilization should be scientifically matched, pay attention to the application ratio of other fertilizers, suggest to apply completely decomposed organic fertilizer or compound fertilizer, so as to take care of each fertility, 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.

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