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]
The present invention relates to a kind of agricultural spray, be specifically related to a kind of chitosan-based anti-freezing antibacterial spraying agent for cutting surfaces of rubber trees and preparation method thereof.
[background technology]
The glue district is planted by China often has microthermal climate winter, causes tapped part of rubber tree to suffer cold damage and disease occurs, and directly affects the output in next year, especially particularly serious for the poor kind of some cold tolerances or temperature is lower in the winter time local freeze injury.Pass the winter safely in order to ensure tapped part of rubber tree, producing vegetable oil prescription commonly used at present, the indigenous method that industrial vaseline and yellow mud are mixed cow dung seals coat with rubber tree face as coating agent, yet these methods are all owing to existence is in various degree used inconvenient, cost is high, has harmful effect or winter protection effect undesirable etc. former thereby be very limited in actual applications to bark; Chinese patent CN92111143.6 also discloses a kind of protecting agent for tapped part of rubber tree, the gluey medicament that is formed by polyvinyl alcohol, efosite, zinc sulphate, ammonium molybdate, growth regulator and additive mixed preparing, employing is coated with the envelope mode and is applied on the face, its raw material is more, use inconvenient, cost is higher, and curative effect is low, need to repeatedly be coated with envelope; Chinese patent CN01106038.7 also discloses the agent of a kind of tapped part of rubber tree anti-frost protection, and by the emulsion that Wax, emulsifier, plant growth regulator, water are made, its raw material type is also more, and production cost is high; Chinese patent CN200610048880.5 also discloses a kind of rubber tree tapping face coldness-proof coating agent and production method thereof, formed by the rubber seed oil of 35-50% and the vaseline of 50-65%, although this coating agent cost is lower, but still be to adopt to be coated with the envelope mode and to put on face, antifreezing effect is undesirable, uses inconvenience, and efficiency is low, and coating agent acts on single without antibiotic effect.Open the processing of cutting tree for being injured, land reclamation and cultivation is planted Jiao Qu and is taked to clip dried-up, or face adopts medical ventolin and pitch mixture to be coated with envelope, as bark beetle eaten into into, then spray 1% malathion or 1% dichlorvos.Not only antifreezing effect is poor for these traditional Winter protection methods, need repeatedly repeat soil and smear coating agent, and function is single, uses the construction trouble, and efficiency is lower, is difficult to reach large-area promoting the use of.
This shows, all there is defective in various degree in the antifreeze coating agent of tapped part of rubber tree that uses at present.
Therefore, also need at present to provide a kind of anti-freezing antibacterial, preparation technology simple, be easy to large-scale production, tapped part of rubber tree anti-frost protection agent easy to use.
