Problems solved by technology

These traditional cold protection methods not only have poor antifreeze effect, but also need to repeatedly apply the sealant, and the function is single, the use and construction are troublesome, the labor efficiency is low, and it is difficult to achieve large-scale promotion and use.
[0003] This shows that the rubber tree face antifreeze sealants currently used all have defects in various degrees.

Abstract

The invention discloses a chitosan-based anti-freezing antibacterial spraying agent for cutting surfaces of rubber trees and a preparation method thereof. The spraying agent contains active ingredients, an additive and a propellant. The active ingredients comprise chitosan, tea-tree essential oil, polyvinyl alcohol, a plant growth regulator and glacial acetic acid. The spraying agent can form a layer of cold-proof antibacterial protective film on cutting surfaces of rubber trees, and not only enables the cutting surfaces of the rubber trees to avoid freezing injury and live through the winter safely and protects the cutting surfaces from bark cracking and gummosis, but also is capable of protecting the cutting surfaces of the rubber trees from infection of pest and disease damages of strip canker, bark beetle and the like. The spraying agent is mild in preparation conditions and simple in preparation process, industrialized production of the chitosan-based anti-freezing antibacterial spraying agent is easy, and the chitosan-based anti-freezing antibacterial spraying agent is convenient to carry and simple to operate.

Description

【Technical field】 [0001] The invention relates to an agricultural spray, in particular to a chitosan-based rubber tree cut surface antifreeze and antibacterial spray and a preparation method thereof. 【Background technique】 [0002] There are often low-temperature weather in winter in rubber planting areas in my country, which leads to cold damage and disease on the cut surface of rubber trees, which directly affects the yield of the next year, especially for some varieties with poor cold resistance or freezing damage in places with low winter temperatures. In order to ensure that the cut surface of rubber trees survives the winter safely, vegetable oil formulations are commonly used in production, and the industrial method of vaseline and yellow mud mixed with cow dung is used as a sealant to seal the cut surfaces of rubber trees. However, these methods are not used due to the existence of different degrees. Convenience, high cost, adverse effects on bark or unsatisfactory c...
