Cold-resistant regulator for effectively inhibiting rubber tree gummosis and application of regulator

Abstract

The invention provides a cold-resistant regulator. Active ingredients of the cold-resistant regulator comprise magnesium sulfate, calcium chloride, chitosan, sodium dimethyl dithiocarbamate, abscisic acid, basil extracting solution and palm oil. All the components of the cold-resistant regulator have a synergistic effect, and the cold-resistant regulator has the functions of improving the photosynthetic efficiency of plants, improving the structural stability of cell membranes, maintaining the fresh weight of the plants and the like; under the effect of low-temperature stress, decrease of chlorophyll content, net photosynthetic rate, intercellular carbon dioxide concentration and the like of rubber tree leaves can be effectively slowed down, and increase of relative conductivity of phloem, malondialdehyde content and the like can be remarkably slowed down; the content of phloem soluble sugar, the maximum photochemical efficiency of leaf PSII, the actual photochemical efficiency of leaf, the content of phloem soluble protein, the content of phloem superoxide dismutase, the activity of phloem peroxidase and the like can be remarkably improved, and damage of low-temperature stress to a phloem cell membrane and a leaf photosynthetic system of a rubber tree is reduced; rubber flowing of the rubber trees is inhibited, and damage of rubber flowing to the rubber trees is reduced.

Description

technical field [0001] The invention relates to a cold-resistance regulator, in particular to a cold-resistance regulator which can effectively inhibit rubber tree flow and its application. Background technique [0002] The cold damage of rubber trees is caused by cold waves, cold air invasion or sudden drop in air temperature. When the temperature drops or the low temperature accumulates below the temperature that rubber trees can tolerate, cold damage occurs. Cold damage often reduces the yield of rubber trees, directly threatens the survival of rubber trees, and affects the economic benefits of cultivating rubber trees. The impact of cold damage on the crown of rubber trees is manifested as mild scorching of young leaves, and in severe cases, the leaves and branches are dry; the impact of mild cold damage on the stems of rubber trees is manifested as black spots, dry outer bark, and dryness of the entire trunk. It is manifested as bursting skin and flowing glue and "rott...
