Method for preventing citrus gonggan fruit cracking

Abstract

The invention relates to the field of fruit tree cultivation, in particular to a method for preventing citrus gonggan fruit cracking. According to the method, water is drained in rainy seasons, irrigation is carried out during droughts, soil water imbalance can be prevented, and flesh expansion and fruit cracking which are caused because fruits absorb too much water are avoided. Scarification and weeding are carried out in time on planting land, nutrition absorption of fruit trees can be enhanced, and healthy growth of the fruit trees is promoted. Fruit cracking caused by malnutrition of part branches and leaves can be avoided due to reasonable pruning. Pericarp toughness can be improved and pericarp growth can be promoted by irrigating fruits with urea or spraying urea on the fruits, and the fruit cracking probability is reduced.

Description

technical field [0001] The invention relates to the field of fruit tree cultivation, in particular to a method for preventing and controlling citrus fruit cracking. Background technique [0002] Fruit cracking is a plant phenomenon in which the fruit cracks or shoots out after the plant is mature. There are many factors that cause fruit cracking, such as fruit structure, environmental conditions, pest damage, cultivation and management conditions, etc., such as drastic changes in soil temperature, pest damage, etc. Both can cause fruit cracking; the imbalance of mineral nutrients such as calcium, nitrogen, potassium, boron, magnesium, zinc, etc. is also an important reason for fruit cracking. Among them, the phenomenon of fruit cracking caused by calcium deficiency is the most common. [0003] Most of the fruit cracking of tribute oranges is caused by the imbalance of endogenous hormones in the fruit. Under drought conditions, the supply and distribution of endogenous hormon...

Problems solved by technology

[0003] Most of the fruit cracking of tribute oranges is caused by the imbalance of endogenous hormones in the fruit. Under drought conditions, the supply and distribution of endogenous hormones in tribute citrus fruits are out of balance, and the growth of peel and pulp cannot be balanced and coordinated, which will cause fruit cracking of tribute oranges.
