Problems solved by technology

However, due to various reasons, the annual loss to production due to the germination rate of cotton seeds is still very serious, and it is very important to do a good job in the detection of germination rate
[0003] At present, domestic research on the germination technology of cotton seeds is still relatively small, and the cotton seed germination technology is commonly used in the industry. The main method is: put warm water at 50-55°C in a clean container, and the amount of water is 5% of the seed volume. double, soak the seeds in warm water and stir continuously, stop stirring when the water temperature drops to 30°C, and then soak for 8 to 12 hours to make the seeds absorb enough water, then drain the water, wrap it with gauze, and then wrap the outside Put soaked sacks or towels in pots for germination. This method is called soaking seeds in warm soup. This is the most commonly used method for germination at present. This method is simple and convenient, but there are many problems: slow seed emergence, bud vigor Weak, irregular emergence, serious phenomenon of large and small seedlings, if the seeds are dormant, the emergence speed will be slower, and the germination rate is low
Cotton is a popular crop and plays an important role in production, but cotton seeds germinate slowly and irregularly, and are prone to natural aging during storage, resulting in reduced vitality. Therefore, how to speed up seed germination and promote seed emergence is very important

Embodiment 1

[0028] A method for accelerating germination of cotton seeds of the present invention, the method comprises the following steps:

[0029] S1, delinting, to the obtained high-residual fluff seeds, inject a dilute sulfuric acid solution with a mass ratio of 12% to the high-residual fluff seeds, and add sodium lauryl sulfate with a final concentration mass ratio of 5%; fully stir, increase Acid soaking time: After the soaked high-residual fluff seeds are dedried by a centrifuge, increase the inlet temperature of the drying drum to 220°C, pass through the grinding drum at a low speed, and roll the grinding drum for 90 minutes to form light seeds;

[0030] S2. Seed selection, drop light seeds from a high place in free fall, and separate heavy impurities, mature seeds, immature seeds and light impurities through horizontal wind force during the free fall process, and select qualified seeds ;

[0031] S3, drug treatment, take an appropriate amount of cotton seeds and put them in a t...

[0038] A method for accelerating germination of cotton seeds of the present invention, the method comprises the following steps:

[0039] S1, delinting, to the obtained high-residual fluff seeds, inject a dilute sulfuric acid solution with a mass ratio of 12% to the high-residual fluff seeds, and add sodium lauryl sulfate with a final concentration mass ratio of 5%; fully stir, increase Acid soaking time: After the soaked high-residual fluff seeds are dedried by a centrifuge, increase the inlet temperature of the drying drum to 245°C, pass through the grinding drum at a low speed, and roll the grinding drum for 75 minutes to form light seeds;

[0040] S2. Seed selection, drop light seeds from a high place in free fall, and separate heavy impurities, mature seeds, immature seeds and light impurities through horizontal wind force during the free fall process, and select qualified seeds ;

Abstract

The invention provides a cotton seed germination accelerating method, which comprises step of removing cotton velvets, picking seeds, processing seeds by a medicament, preprocessing seeds before soaking, soaking seeds, culturing the seeds, and inspecting the buds. The provided method can obviously increase the germination rate, germination vigor, and seedling quality of cotton seeds.

Description

technical field [0001] The invention relates to the technical field of cotton breeding, in particular to a method for accelerating germination of cotton seeds. Background technique [0002] As the most basic means of production, cotton seeds play a very important role in cotton production. The germination rate of cotton seeds is one of the important indicators of the quality of cotton seeds. With the continuous improvement of the industrialization of cotton seeds, refined cotton seeds such as delinting and coating are widely used in production, which greatly improves the quality of cotton seeds, especially The germination rate of cotton seeds was significantly improved. However, due to various reasons, the annual loss to production due to the germination rate of cotton seeds is still very serious, and it is very important to do a good job in the detection of germination rate. [0003] At present, domestic research on the germination technology of cotton seeds is still rela...
