Sugarcane cold-resistant composition

Abstract

The invention relates to the technical field of pesticides, in particular to a sugarcane cold-resistant composition. The sugarcane cold-resistant composition is prepared from the effective constituents of salicylic acid and ethylene with the mass ratio of (5-30):1. The sugarcane cold-resistant composition is sprayed before sugarcane is subjected to low temperature stress, the content of chlorophyll in the sugarcane can be increased, the number of green leaves is kept to be normal, and the content of soluble sugar and soluble protein is increased, the increase of the content of the biochemicalsubstances can improve the concentration of the cell sap, the water holding capacity of the cells is enhanced, and the freezing point is reduced; the over oxidation degree of the cytomembrane can alsobe reduced, so that the sugarcane leaf cytomembrane structure is stable, thereby improving the cold resistance of the body and facilitating the resistance to low temperature and disasters of the sugarcane.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a sugarcane cold-resistant composition. Background technique [0002] Sugarcane (Saccharum officenarum L.) is a plant belonging to the genus Saccharum in the Gramineae family, belonging to tropical and subtropical crops. It has high photosynthetic efficiency, high light saturation point, low carbon dioxide compensation point, low photorespiration rate, and high photosynthetic intensity, but it has a certain impact on natural resources. requirements, especially for temperature and moisture. In my country, in recent years, the climate has changed abnormally, and extreme low temperatures occur frequently. Sugarcane often suffers from natural low temperature damage in the late growth period. The low temperature seriously affects the development of sugarcane production and sugar industry production, resulting in economic losses of varying degrees. Sugarcane planted in subtropical ...

Problems solved by technology

Frost disasters have occurred frequently in winter and spring in the sugarcane areas in central my country and in sugarcane planting bases such as Sichuan and Jiangxi in recent years, affecting the harvest and transportation of sugarcane, and also affecting the germination of perennial sugarcane. When it occurs in spring, it will affect the germination rate of sugarcane species and the growth of seedlings. The quality of sugarcane reduces the yield per mu of sugarcane, and the sugar factory does not have enough raw cane, which also hinders the production of sugar enterprises, and also causes serious economic losses to the income of sugarcane farmers.

[0003] At present, in order to prevent the impact of low temperature disasters on sugarcane, cultivation methods such as fumigation and irrigation are generally used, but it is labor-intensive and time-consuming, which increases production costs and is not easy to operate.
