Prevention and treatment method of freezing damage of loquat flower and fruit

Abstract

The invention discloses a prevention and treatment method of the freezing damage of loquat flower and fruit, which comprises the following step of: spraying a CaCl2 (calcium chloride) solution with the concentration of 1-3g / L to a crown of a loquat tree 3-5 days before the coming of frosty weather with the daily minimum temperature of below zero DEG C or the daily highest relative humidity of larger than or equal to 95% according to the weather forecast during the during the period of blossom and fructify of the loquat tree in autumn and winter. When the method is adopted, the influence on loquat due to the freezing damage can be effectively reduced; loss is reduced; the period of growth and recovery of the loquat after the freezing damage is shortened; the fruit quality of the loquat is improved; the yield is increased; the method is beneficial for early maturing; and the economic benefit of peasants is increased.

Description

technical field [0001] The invention belongs to the technical field of preventing and controlling freezing damage of crops, in particular to the technical field of preventing and controlling freezing damage of loquat flowers and fruits. Background technique [0002] Loquat is a health-care fruit originating in China. It is warm and humid in nature and has broad development prospects. Generally, it blooms and sets fruit in autumn and winter, and the low temperature in winter coincides with the bud stage, flowering stage, and young fruit stage. Loquats are susceptible to different degrees of freezing damage, resulting in a substantial reduction in production. In recent years, with the deterioration of the global climate and environment, the frequency of natural disasters such as frost has increased, which has affected the yield and quality of loquat to varying degrees, and has become a bottleneck restricting the sustainable development of loquat. Therefore, understanding the ...
