Regulating composition used for protecting flowers and fruits of citrus and application of regulating composition used for protecting flowers and fruits of citrus

Abstract

The invention relates to the technical field of fruit industry, and particularly discloses a regulating composition used for protecting flowers and fruits of citrus and application of the regulating composition used for protecting the flowers and the fruits of the citrus. The regulating composition comprises in percentage by mass: 1-10% of flower and fruit regulating factors and 90-99% of assistants; and the flower and fruit regulating factors contain 0.5%-6% of benayl aminopurine, 0.5%-6% of gibberellic acid and 0-0.01% of brassinolide (on the basis of scalar). The regulating composition canbe made into liquor, powder or granules, and is sprayed onto the citrus from a bud stage to a second physiological fruit drop stage. Germination and fruit setting of the citrus can be effectively promoted, flower and fruit drop is reduced, the fruit setting rate is significantly improved, the deformed individual rate is reduced, the fruit type is corrected, the citrus fruits taste thick and sweet,the fruits are even in size, fruit peel is smooth, bright and beautiful, the size evenness of the citrus fruits is up to 90% or above, the deformed individual rate is as low as 0.5-3.5%, the fruit setting rate is up to 8-17.5%, the yield per plant can be improved by 9.5-20.8%, and the quality and the yield of the citrus fruits can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of fruit industry, and in particular relates to a regulating composition for preserving flowers and fruits of citrus and an application thereof. Background technique [0002] my country is one of the origins of citrus, and the output of citrus ranks first in the world. Citrus is cultivated in 19 provinces (regions) and cities in my country, and it is the most important fruit tree in the south. However, due to the natural growth environment of citrus, citrus has more flowers and less fruit, and there is a serious phenomenon of flower and fruit drop. Citrus flower and fruit drop can be roughly divided into five stages: bud drop, flower drop, the first physiological fruit drop, and the second time. Physiological fruit drop, pre-harvest fruit drop. After the above process, the fruit setting rate of citrus is very low, and the fruit setting rate is generally only 0.3-5%. How to preserve flowers and fruits is a ...

Problems solved by technology

[0003] The main fruit-preserving drugs used for citrus on the market include plant growth regulators such as 2,4-D, gibberellin (gibberellic acid A3), cytokinin, paclobutrazol, and forchlorfenuron. The fruit-preserving effect is good, but it will cause A series of side effects, such as rough skin, deformed fruit, etc., affect fruit quality

Gibberellins have adverse effects on citrus, manifested as citrus leaves become larger and thinner, and turn green slowly; while the effects on fruits are manifested as many small fruits, thickened and rough peels, and reduced quality
