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 ad

Embodiment 1

[0019] The cotton seed germination accelerator described in this embodiment is composed of the following components and mass percentage content: 0.5% chitosan, 0.2% calcium chloride, 0.005% gibberellin, and the rest is water.

[0020] The preparation method of the cotton seed germination accelerator is as follows: after dissolving chitosan into a small amount of acetic acid with negligible weight, adding calcium chloride, gibberellin and part of water, completely dissolving, mixing evenly, and adding water to constant volume.

[0021] The method of using the cotton seed germination accelerator is as follows: the seed initiator is diluted 80 times with water and mixed with the volume of cotton seeds at 2:1, soaked at 25°C for 24 hours, the seeds are filtered out, and rinsed with water for 2-2 hours. 3 times, dry after absorbing moisture, control the water content at 8%±0.5%, and immediately sow or store the seeds.

Embodiment 2

[0023] The cotton seed germination promoter described in this embodiment is composed of the following components and mass percentage content: 0.1% chitosan, 0.3% calcium chloride, 0.008% gibberellin, and the rest is water.

[0024] The preparation method of the cotton seed germination accelerator is as follows: after dissolving chitosan into a small amount of acetic acid with negligible weight, adding calcium chloride, gibberellin and part of water, completely dissolving, mixing evenly, and adding water to constant volume.

[0025] The method of using the cotton seed germination promoter is as follows: the seed initiator is diluted 50 times with water and mixed with the volume of cotton seeds at 1:1, soaked at 25°C for 24 hours, the seeds are filtered out, and rinsed with water for 2-2 hours. 3 times, dry after absorbing moisture, control the water content at 8%±0.5%, and immediately sow or store the seeds.

Embodiment 3

[0027] The cotton seed germination promoter described in this embodiment is composed of the following components and mass percentage content: 1.0% chitosan, 0.1% calcium chloride, 0.002% gibberellin, and the rest is water.

[0028] The preparation method of the cotton seed germination accelerator is as follows: after dissolving chitosan into a small amount of acetic acid with negligible weight, adding calcium chloride, gibberellin and part of water, completely dissolving, mixing evenly, and adding water to constant volume.

[0029] Dilute the seed initiator 50 times with water and mix it with cotton seeds at a volume of 1:1, soak for 30 hours at 20°C, filter out the seeds, rinse with water for 2 to 3 times, dry after absorbing moisture, and control the water content at 8%±0.5%, the seeds are sown or stored immediately.

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...
