A kind of anti-cold regulator and application of effectively inhibiting rubber tree flow

Abstract

The invention provides a cold resistance regulator, the active ingredient of which comprises magnesium sulfate, calcium chloride, chitosan, sodium thiram, abscisic acid, basil extract and palm oil. The components of the cold resistance regulator of the present invention act synergistically, and have functions such as improving plant photosynthetic efficiency, improving cell membrane structure stability, and maintaining plant fresh weight; under low temperature stress conditions, it can effectively slow down the chlorophyll content of rubber tree leaves, net photosynthetic rate, The decrease of intercellular carbon dioxide concentration can significantly slow down the increase of the relative conductivity of the phloem and the content of malondialdehyde, etc., and can significantly increase the content of soluble sugar in the phloem, the maximum photochemical efficiency of PSII in leaves, the actual photochemical efficiency of leaves, and the content of soluble proteins in phloem. content, phloem superoxide dismutase content, phloem peroxidase activity, etc., reduce the damage of low temperature stress to the phloem cell membrane and leaf photosynthetic system of rubber trees, inhibit the flow of rubber trees, and reduce the damage of rubber trees to rubber trees.

Description

Technical field [0001] The present invention relates to a cold modulator, and more particularly to a cold modifier and application effective inhibiting rubber tree fluid. Background technique [0002] The chill of the rubber tree suddenly decreases by the cold wave, the cold air invasion or the air temperature, when the temperature is lowered or low temperature accumulates to the rubber tree, the cold is chill. Cold damage often reduces rubber tree production, and also directly threatens the survival of rubber trees, affecting the economic benefits of cultivating rubber trees. The influence of cold and rubber trees is illustrative as a tender leaf affection. When severe, the blade is dead and the branches are dry; mild chills have a dry effect of rubber stalks, and the outer tree bark is dry, and the whole trunk is dry, heavy The performance is "rotten" in the binder fluid and the base; the effect of the root system is the main root leather blast or dry, the side roots are dry, a...

Problems solved by technology

In addition, cold damage can also cause bark beetle, powdery mildew and anthracnose and other diseases and insect pests, which not only lead to growth retardation, but severe damage may also lead to plant death
