Flower-thinning agent of apple tree and flower-thinning treatment method

Abstract

The invention discloses a flower-thinning agent of apple trees, wherein the flower-thinning agent is a mixed aqueous solution prepared from calcium formate and carbaryl. The mass concentration of the calcium formate is 5-10 g / L and the mass concentration of the carbaryl is 0.5-1 g / L. The invention also discloses a flower-thinning treatment method which includes the steps of: (a) preparation of the flower-thinning agent: preparing the mixed aqueous solution from the calcium formate and the carbaryl according to the mass concentration of the calcium formate being 5-10 g / L and the mass concentration of the carbaryl being 0.5-1 g / L; (b) spraying of the flower-thinning agent onto apple trees: after 5-10 days of the full-blossom period of the apple trees, spraying the flower-thinning agent onto the apple trees requiring flower-thinning treatment; and (c) assistant fruit dropping: after 10-12 days after the flower-thinning agent is sprayed, shaking the apple trees manually and thinning the flower with fruit thinning shears. By means of the flower-thinning agent for flower thinning with assistant fruit dropping in the manners of manual shaking and fruit thinning with fruit thinning shears, the problem of excessive blossom of the apple trees is solved. The flower-thinning agent can increase fruit size, can improve the quality of fruits and can prevent the phenomenon of harvest / poor harvest by years.

Description

technical field [0001] The invention relates to the technical field of fruit tree flower thinning and fruit thinning, in particular to an apple tree flower thinning agent and a flower thinning treatment method thereof.
