Longan fruit thinning agent

Abstract

The invention belongs to the technical field of agricultural fruit thinning of fruit trees, and relates to a longan fruit thinning agent. The longan fruit thinning agent is prepared by uniformly mixing carbamide, diflubenzuron, amino acid and water and achieves the purpose of fruit thinning by accelerating the drop of weak fruits by being sprayed to a longan crown which needs fruit thinning and then manually vibrating the 2-level branches of a longan tree. The longan fruit thinning agent disclosed by the invention can be used for effectively thinning the weak fruits and retaining the fruits with high fruit setting power by scientifically blending a medicament according to a longan fruit load regulation mechanism, can meet the requirement for better fruit thinning, increase the fruit thinning efficiency under the precondition without influencing the late management work of longan and solve the problems of high labor intensity, low efficiency, high expenditure, poor effect and the like of the traditional manual fruit thinning, has the characteristics of easiness for operation, good effect, low cost and the like and plays an important directing role in high-efficiency orchard management.

Description

technical field [0001] The invention belongs to the technical field of fruit thinning of agricultural fruit trees, and relates to a fruit thinning technology of young longan trees, in particular to a longan fruit thinning agent. Background technique [0002] The longan tree (Dimocarpus longan Loureiro) is an evergreen tree, and its fruit—longan, together with litchi, banana, and pineapple—is one of the four rare fruits in South China. Longan trees have a very strong fruit setting rate under normal conditions, and they are known as "love fruit and don't spare the tree". A medium-sized longan tree can bear more than 40 fruit per ear, while a well-managed longan tree can bear 70 fruit per ear. grains or more. Excessive fruit burden will lead to a decline in the state of the tree. At the same time, due to the large amount of fruit, the weight of the single fruit will be low and the quality will be poor. Therefore, it is often necessary to thin the fruit in the young fruit stage...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of longan fruit thinning agent in view of the deficiencies in the prior art. According to the longan fruit load adjustment mechanism, the agents are scientifically compatible, which can achieve better fruit thinning requirements, effectively improve fruit thinning efficiency, and solve the problem of longan fruit thinning. It solves the existing artificial fruit thinning problems such as high labor intensity, low efficiency, high cost, and poor effect, and has an important guiding role in the management of high-effect gardens
