Embodiment 1

[0019] The preparation method of the seed coating agent of the present embodiment is as follows:

[0020] Preparation raw materials: Potassium permanganate 1g, benzylamine 2g, vitamin B 6 1g, manganese sulfate 2g, zinc sulfate 2g, ammonium molybdate 2g, chitosan oligosaccharide 2g, potassium dihydrogen phosphate 1g, amytal 0.5, starch 9g.

[0021] Add 9g of starch into 100ml of water, stir evenly, heat and stir evenly to form a paste to obtain film-forming milk; add the remaining raw materials to the film-forming milk, and stir rapidly for 30 minutes to obtain a seed coating agent.

[0022] Use the seed coating agent prepared in this example to add 100 ml of the seed coating agent to 1 kg of photonic cotton seeds and mix evenly to treat the cotton seeds. After the treatment is dried, they are sown, and then the indicators in the cotton growth process are measured. Among them, the effects of seed coating agents on the number of lateral roots and seedling height of cotton seedl...

Embodiment 2

[0024] The preparation method of the seed coating agent of the present embodiment is as follows:

[0025] Preparation raw materials: Potassium permanganate 2g, benzylamine 3g, vitamin B 6 1g, manganese sulfate 3g, zinc sulfate 3g, ammonium molybdate 3g, chitosan oligosaccharide 3g, potassium dihydrogen phosphate 2g, Aimite 0.7, starch 9g.

[0026] The preparation method of the present embodiment seed coating agent is the same as embodiment 1.

[0027] Using the seed coating agent prepared in this example, 100ml of the seed coating agent was added to 1kg of photonic cotton seeds and mixed evenly to treat the cotton seeds, and then sowed after drying, and then the indicators in the cotton growth process were measured. Among them, the effect of seed coating agent on the number of lateral roots and seedling height of cotton seedlings is shown in Table 1, the determination of root activity is shown in Table 2, the photosynthetic rate of leaves is shown in Table 2, the invertase ac...

Embodiment 3

[0029] The preparation method of the seed coating agent of the present embodiment is as follows:

[0030] Preparation raw materials: Potassium permanganate 1g, benzylamine 4g, vitamin B 6 4g, 5g of manganese sulfate, 4g of zinc sulfate, 4g of ammonium molybdate, 5g of chitosan oligosaccharide, 1g of potassium dihydrogen phosphate, 0.9 of amite, 9g of starch.

[0031] The preparation method of the present embodiment seed coating agent is the same as embodiment 1.

[0032] Use the seed coating agent prepared in this example to add 100 ml of the seed coating agent to 1 kg of photonic cotton seeds and mix evenly to treat the cotton seeds. After the treatment is dried, they are sown, and then the indicators in the cotton growth process are measured. Among them, the effect of seed coating agent on the number of lateral roots and seedling height of cotton seedlings is shown in Table 1, the determination of root activity is shown in Table 2, the photosynthetic rate of leaves is shown...

Abstract

The invention discloses a cotton seed coating agent with the effects of promoting roots and strengthening seedlings and a preparation method thereof. The seed coating agent is prepared from, by weight, 1-2 parts of potassium permanganate, 2-4 parts of mepiquat chloride, 1-4 parts of vitamin B6, 2-5 parts of manganese sulfate, 2-4 parts of zinc sulfate, 2-4 parts of ammonium molybdate, 2-5 parts of chitosan oligosaccharide, 1-2 parts of monopotassium phosphate, 0.5-1.0 part of emistim and 9-10 parts of a film forming agent. The preparation method comprises the steps that the film forming agent is added into water, the materials are fully stirred to be uniform, then the mixture is heated under uniform stirring to form paste, and film forming emulsion is obtained; the remaining raw materials are added into the film forming emulsion, quick stirring is conducted for 30 min, and the seed coating agent is obtained. A using method of the seed coating agent comprises the steps that the seed coating agent is manually added into naked seed cotton seeds according to the ratio 1 ml:10 g of the seed coating agent to the seeds, the materials are stirred to be uniform, air drying is conducted, and then coated seeds are obtained. According to the cotton seed coating agent and the preparation method thereof, the formula is simple, the preparation technology is simple and easy to operate, the cost is low, growth of cotton seedling root systems is effectively promoted, the root activity and the invertase activity are obviously improved, the photosynthetic rate of cotton leaves is obviously increased, and the cotton yield is significantly increased.

Description

technical field [0001] The invention belongs to the field of cotton seed coating agents, in particular to a cotton seed coating agent for promoting roots and strengthening seedlings and a preparation method thereof. Background technique [0002] Crop seed coating treatment is a disinfection measure for seeds, which can effectively prevent and control pests and diseases at the seedling stage, promote seed germination, and enable cotton to achieve strong seedlings and early germination. One of the important symbols of commercialization and industrialization, the application of seed coating agent technology on rapeseed has been successful. [0003] Cotton is an important economic crop, and early emergence of strong seedlings is a prerequisite for high-quality and high-yield cotton. In actual production, in addition to selecting seeds and sowing them at the right time to ensure the quality of sowing, high-quality cotton seeds must also be coated. At present, the coating of cott...
