Cotton seed germination promoter

Abstract

The invention provides a cotton seed germination promoter, which is prepared from the following ingredients in percentage by mass: 0.1 to 1.0 percent of chitosan, 0.1 to 0.3 percent of calcium chloride, 0.002 to 0.008 percent of gibberellins and the balance water. After the promoter is diluted, seed soaking is performed. The chitosan is used for improving the activity of various antioxidases in a plant body; the production of various plant pathogenic microorganisms is inhibited; the plant disease-resistant capability is enhanced; the damage of low-temperature threatening and draught threatening to the plant is relieved; the seed dormancy is broken through addition of gibberellins; the effect of promoting the seed germination and young seedling growth can be achieved; the low-temperature injury of seeds in the germination period is relieved; the germination rate of the seeds in adverse environment can be obviously improved; meanwhile, the nutrition elements required by the plant growth and development are increased by using the calcium chloride; each aspect of the plant growth and development is regulated; the content of calmodulin can be improved; the seed activity is enhanced; the emergence rate and the stocking rate of the cotton seeds in low-temperature cold damage environment are finally improved.

Description

technical field [0001] The invention relates to the technical field of seed treatment, in particular to a cotton seed germination accelerator. Background technique [0002] my country's cotton production ranks among the top in the world. It is a large textile country and the largest cotton consumer. There are 23 provinces, municipalities and autonomous regions that produce cotton. The cotton industry occupies an important position in the national economy. The main and by-products of cotton have high utilization value. As the predecessors said, "cotton is all treasures." It is not only the most important fiber crop, but also an important oil crop, a high-protein food crop, or a textile , fine chemical raw materials and important strategic materials. Therefore, efforts must be made to increase cotton production, improve comprehensive utilization, increase production and increase value, so as to increase the income of cotton farmers and meet the various needs of national econo...

Problems solved by technology

[0003] In recent years, while the global climate has been slowly warming, the frequency of extreme climate changes has increased, and the unevenness of cold and heat has caused frequent low-temperature and cold damage such as freezing injury and frost injury, resulting in a decrease in the emergence rate and seedling rate of cotton; on the other hand, in order to To maximize the use of light and heat resources and to expand the growth period of cotton, people have adopted technical measures such as mulch cotton planting to gradually advance the sowing period of cotton, but the temperature changes in spring are unstable, and the "cold spring" has brought serious harm to cotton production. The cold and wet environment leads to difficulties in cotton seedling emergence, rotten seeds, rotten roots, lack of seedlings and broken ridges, and even damaged seeds for replanting. This not only affects the further increase of cotton yield, but also causes a serious decline in cotton quality. Low temperature is one of the important factors affecting cotton seedling emergence one
