Embodiment 1

[0017] In the embodiment of the present invention, a cotton seedling raising method, the specific method is as follows:

[0018] (1) Selection and treatment of seeds

[0019] In late March, the cotton seeds with full grains, no insect eyes, no mold and lint were selected as cotton seeds. After the cotton seeds were air-dried for 64 hours, they were put into a rotary machine with a speed of 9700r / min for 34 minutes, and they were soaked in the seed soaking agent for 75 minutes. Dry until the moisture content is 19%-21%;

[0020] The seed soaking agent is made from the following raw materials in parts by weight: 1.7 parts of mutton ester, 0.8 parts of dill oil brain, 7.7 parts of chickweed extract, 9 parts of cocklebur seed extract, and 3.8 parts of artemether;

[0021] (2) Sowing and management after sowing

[0022] Sow the cotton seeds treated in step (1) in the nursery substrate in the nursery shed, one seed per hole, and use the light intensity of 44~48Lx for light treatment at 22:00...

Embodiment 2

[0027] In the embodiment of the present invention, a cotton seedling raising method, the specific method is as follows:

[0028] (1) Selection and treatment of seeds

[0029] In late March, the cotton seeds with full grains, no insect eyes, no mold and lint were selected as cotton seeds. After the cotton seeds were air-dried for 66 hours, they were put into a rotary machine with a speed of 9800r / min for 36 minutes, and they were soaked in the seed soaking agent for 78 minutes. Dry until the moisture content is 19%-21%;

[0030] The seed soaking agent is made of the following raw materials in parts by weight: 1.8 parts of mutton ester, 0.85 parts of dill oil brain, 8 parts of chickweed extract, 9.5 parts of xanthium extract, and 4.1 parts of artemether;

[0031] (2) Sowing and management after sowing

[0032] Sow the cotton seeds treated in step (1) in the nursery substrate in the nursery shed, one seed per hole, and use the light intensity of 44~48Lx for light treatment at 22:00~4:00 e...

Embodiment 3

[0037] In the embodiment of the present invention, a cotton seedling raising method, the specific method is as follows:

[0038] (1) Selection and treatment of seeds

[0039] In late March, the cotton seeds with full particles, no insect eyes, no mold and lint were selected as cotton seeds. After the cotton seeds were dried for 68 hours, they were put into a rotary machine with a speed of 9900r / min for 38 minutes, and they were soaked in the seed soaking agent for 80 minutes. Dry until the moisture content is 19%-21%;

[0040] The seed soaking agent is made of the following raw materials in parts by weight: 1.9 parts of mutton ester, 0.9 parts of dill oil brain, 8.3 parts of chickweed extract, 10 parts of cocklebur seed extract, and 4.4 parts of artemether;

[0041] (2) Sowing and management after sowing

[0042] Sow the cotton seeds treated in step (1) in the nursery substrate in the nursery shed, one seed per hole, and use the light intensity of 44~48Lx for light treatment at 22:00~4...

Abstract

The invention belongs to the technical field of cotton planting, and particularly relates to a cotton seedling culture method. The specific method includes the steps of (1) seed selection and treatment, wherein cotton seeds are aired and then put into a rotating machine for rotating treatment, and the cotton seeds are put into a seed soaking agent for soaking and then aired till the moisture is 19%-21%; (2) sowing and after-sowing management, wherein the cotton seeds are sown in a seedling culture medium in a seedling culture shed, light treatment with the light intensity of 44-48 Lx is conducted at 22:00-4:00 every day after emergence, ventilation treatment is conducted at 10:00-15:00 every day after the seedlings send forth one true leaf, and root application of a nutrient solution is carried out 8-9 days before transplanting. By means of the method, the cotton emergence time is shortened to 7.9-8.2 days, the emergence rate reaches 98.41%-98.77%, the blight rate is reduced to 1.45%-1.56%, the anthracnose rate is reduced to 1.23%-1.32%, and the transplanting survival rate reaches 98.5%-98.8%.

Description

Technical field [0001] The invention belongs to the technical field of cotton planting, in particular to a cotton seedling raising method. Background technique [0002] Cotton is an important economic crop in China. It has been planted in China for more than 2,000 years. Its planting area and output rank first in the world. However, blight and anthracnose are prone to occur in the process of cotton seedling raising. Slow emergence and unsatisfactory emergence rate have greatly adversely affected the number of seedlings and the quality of seedlings, resulting in low transplant survival rate, poor disease resistance after transplantation, and disease proneness, which seriously affects the yield of cotton; therefore, invented a The cotton seedling raising method that can effectively solve the above problems to improve the quantity and quality of seedlings is of great significance to the cotton planting industry. Summary of the invention [0003] In view of the above problems, the pr...
