Method for preventing high-temperature damage to loquats and cherries

Abstract

The invention discloses a method for preventing high-temperature damage to loquats and cherries. The method comprises the steps as follows: loquat trees and cherry trees are planted in a greenhouse, the light transmission and ventilation of the loquat trees and cherry trees are good through pruning and other operations, and water spray pipes, solar fans and shading nets are mounted at the top of the greenhouse; loquat and cherry roots are fertilized with farmyard manure, watered and covered with soil; from the fruiting period to the ripe period of the loquats and cherries, cooling is performed through water spraying with atomizing nozzles, blowing with the solar fans and shading with the shading nets in the high-temperature period, the roots are fertilized with farmyard manure and watered for cooling, the effects of high-temperature damage on fruit trees can be effectively reduced, and besides, the water spray pipes spray lime emulsions and thiophanate methyl wettable powder diluents to reduce disease and pest damage.

Description

[0001] Technical field: [0002] The invention relates to the technical field of fruit tree planting, in particular to a method for preventing high-temperature heat damage of loquats and cherries. [0003] Background technique: [0004] Loquat is an evergreen tree, which is evergreen all the year round, let it grow naturally, the growth potential of the terminal bud is strong, and the growth potential of the axillary bud is weak. Become the central branch and extend upward, and the axillary buds become side branches to expand around. Therefore, the central stem of the loquat is very obvious, and the tree body has obvious layers. As time goes by, the loquat tree is divided into one layer, two layers, three layers, and four layers, and finally becomes a spinning and hanging type. The tree body is very beautiful, and it is especially suitable as a greening tree species. beautify environment. [0005] Cherry, also known as wedge jingtao, cherries, etc., is a collective name for c...

Problems solved by technology

[0006] Both loquat and cherry are economical crops, and they are afraid of high temperature burning during the growth process. On the one hand, high temperature can easily cause atmospheric dryness, increase crop water evaporation, reduce soil moisture, and cause drought; Aggravate the water evaporation and loss of branches and leaves, directly affect the development of young fruit, leading to the occurrence of "physiological fruit drop"; high temperature and drought will reduce the photosynthesis of fruit trees, increase the respiration intensity of fruit trees, reduce the synthesis and accumulation of organic nutrients, and then affect the growth of young fruit and flower bud differentiation; Drought often causes "sunburn" of branches and fruits, aggravating the damage of powdery mildew, spider mites, leaf miners and other diseases and insect pests
