Anti-freezing technology for pomegranate trees

Abstract

The invention discloses an anti-freezing technology for pomegranate trees. The anti-freezing technology for the pomegranate trees comprises the following steps: (1) selecting a land and building a garden; (2) building a windbreak; (3) performing flower thinning and fruit thinning; (4) harvesting in time; (5) trimming in winter and summer; (6) whitewashing trunks; (7) performing trunk ridging; (8) covering the garden with grass; and (9) performing pesticide protection. A small weather condition for reducing freeze injuries is created in the aspect of physical conditions and by building the garden and the windbreak, so that general freeze injuries are reduced; the growth potential of the trees is improved and the cold-resistant capability of the trees is enhanced by managing flowers and fruits and trimming in winter and summer; and extreme weather is responded comprehensively by the methods of whitewashing the trunks, performing trunk ridging, covering the garden with grass and performing pesticide protection, so that freeze injuries of the pomegranate trees are avoided and production loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of pomegranate planting, and in particular relates to an antifreeze technology for pomegranate fruit trees. Background technique [0002] Pomegranate trees are subtropical and temperate fruit trees, and freezing damage will occur when the absolute low temperature is ≤ -13°C. There are many reasons why pomegranate trees are frozen, among which the change of ambient temperature is the main reason. When the outside temperature is close to or lower than the low temperature that the pomegranate tree can withstand, the branch stem cells will freeze and expand, thereby causing the death of the cambium cells, resulting in dry branches and even the death of the whole plant. Pomegranate trees over 5 years old have better growth vigor, branches have a high degree of lignification, and enter the dormant period earlier, so they have strong resistance and are not easy to be frozen; The degree of chemicalization is low, ...

Problems solved by technology

[0004] In recent years, extreme weather has frequently occurred, and fruit farmers have not paid enough attention to the prevention and control of pomegranate fruit tree freeze damage, which has affected the fruit production of pomegranate orchards, and even seriously caused fruit trees to freeze to death, resulting in heavy losses
