Fruit retention agent for litchis

Abstract

The invention provides a fruit retention agent for litchis. The fruit retention agent is prepared from the following components in parts by weight: 50-100 parts of cytokinin, 5-30 parts of gibberellin, 15-35 parts of an anti-falling agent, 10-50 parts of borax, 3-6 parts of sodium salt, 20-50 parts of rare earth, 80-320 parts of amino acid, 60-180 parts of calcium acetate, 5-40 parts of fulvic acid and 10-30 parts of chlorophenoxyacetic acid. The fruit retention agent for litchi provided by the invention can prevent litchi fruits from dropping due to insufficient nutrients in the fruit settingperiod of litchi, improve the fruit setting rate of litchi, promote the growth of fruit stems and fruits, improve the quality of fruits, prevent abnormal growth of pulp, prevent fruits from crackingin the later period and realize a good fruit retention effect according to the growth and development characteristics of litchi.

Description

technical field [0001] The invention relates to the technical field of litchi fruit drop prevention, in particular to a fruit preserving agent for litchi. Background technique [0002] Physiological fruit drop of litchi trees is a common phenomenon. The main reasons are: nutritional deficiencies, pest damage, nutritional deficiencies, etc. At present, there are three kinds of litchi fruit preservation agents: "plant growth regulator type", "nutrition type" and compound type. The effect of pure plant growth regulator is better, but the side effects are relatively large, and it is easy to produce deformed fruit; the trophic type has no effect of plant growth regulator, and the fruit preservation effect is limited; the chloride ion in the compound preparation will affect the quality of the fruit, which will lead to pulp loss. Abnormal growth, causing the fruit to crack at a later stage. Existing lychee fruit preservation agent can not play good fruit preservation effect. Co...

The effect of pure plant growth regulator is better, but the side effects are relatively large, and it is easy to produce deformed fruit; the trophic type has no effect of plant growth regulator, and the fruit preservation effect is limited; the chloride ion in the compound preparation will affect the quality of the fruit, which will lead to pulp loss. Abnormal growth that causes the fruit to crack at a later stage

Existing lychee fruit preservation agents cannot play a good role in fruit preservation
