Abstract

The invention relates to a rubber tree cold-resistant agent and application thereof. Active ingredients of the rubber tree cold-resistant agent include chitosan and dithiocar-bamate; and furthermore, the active ingredients of the rubber tree cold-resistant agent also include abscisic acid and cytokinin. Leaves and branches of rubber tree budlings and coppice shoots are sprayed in advance, so that the cold resistance of the rubber tree budlings and coppice shoots can be improved; and in the recovery processing for cutting plane chilling damage, cambiums and phloem can be recovered within six months after the novel rubber tree chilling damage cutting plane cold-proof recovery agent is sprayed. The rubber tree cold-resistant agent disclosed by the invention has the characteristics of being low in cost, simple to prepare, easy to operate and high in efficiency, and saving labor, and can be popularized and applied in rubber tree rubber yards.

Description

technical field [0001] The invention relates to the adversity resistance of forest trees against low-temperature freezing damage, in particular to a rubber tree anti-cold agent and application thereof. 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. The types of cold damage to rubber trees can be divided into three types: advection type, radiation type and mixed type. Advective cold damage is caused by long-term cold weather, lack of sunshine, and wind and cold under the long-term control of cold fronts or stationary fronts. Affected by advective cold damage, the main manifestations are that spots first appear on the leaves and young leaves, which gradually expand and become dry, sometimes gradually spreading to old branches and trunks, and even the ...
