Embodiment 1

[0036] The catechol solution with a concentration of 80mg / ml is mixed with Kaifeng Bianliang Jinyiwei cotton seed coating agent in a ratio of 2:8 (v / v) to form a coating solution, and the diluted coating solution is placed in in a clean container. When using the coating solution, the ratio of liquid: seed is 35:1 (ml / kg), atomized and sprayed on the surface of the seeds, so that the coating solution is evenly wrapped on the surface of the seeds, and then dried in a cool and ventilated place to complete the cotton The capsule of the seed.

Embodiment 2

[0038] Use the catechol solution with a concentration of 60mg / ml and Kaifeng Bianliang Jinyiwei cotton seed coating agent to mix evenly in a ratio of 2:7 (v / v) to form a coating solution, and place the diluted coating solution in in a clean container. When using the coating solution, the ratio of liquid: seed is 30:1 (ml / kg), atomized and sprayed on the surface of the seeds, so that the coating solution is evenly wrapped on the surface of the seeds, and then dried in a cool and ventilated place to complete the cotton The capsule of the seed.

Embodiment 3

[0040] The catechol solution with a concentration of 100 mg / ml is mixed with the Kaifeng Bianliang Jinyiwei cotton seed coating agent in a ratio of 2:9 (v / v) to form a coating solution, and the diluted coating solution is placed in in a clean container. When using the coating solution, the ratio of solution: seed is 40:1 (ml / kg), atomized and sprayed on the surface of the seeds, so that the coating solution is evenly wrapped on the surface of the seeds, and then dried in a cool and ventilated place to complete the cotton The capsule of the seed.

Abstract

The invention belongs to the technical field of plant seed coating, and particularly discloses a catechol-based seed coating method. The catechol-based seed coating method comprises the following steps: uniformly mixing a catechol solution with the concentration of 60-100 mg / ml and a coating agent according to a ratio of 2:(7-9) (v / v) to obtain a coating solution; and then atomizing the coating solution by using a special seed coating machine according to the ratio of the coating solution to the seeds of (30-40):1 (ml / kg), uniformly coating the surfaces of the seeds with the atomized coating solution, and firmly attaching the dried catechol to the surfaces of the seeds in a film form to finish the coating of the seeds. According to the catechol-based seed coating method disclosed by the invention, the vigor of the seeds can be adjusted, the emergence rate is increased, and meanwhile, the growth of seedlings is promoted.

Description

technical field [0001] The invention relates to the technical field of plant seed coating, in particular to a catechol-based seed coating method. Background technique [0002] It is relatively easy to control the environmental conditions, concentration and time of the application of plant growth regulating substances before sowing. Not only is the effect more stable than field application, but the effect of regulating substances can also be extended to the later growth and development of plants. Morphological indicators, physiological and biochemical reactions, and stress resistance have a continuous impact, thereby improving the effectiveness of the regulator, and can significantly reduce the labor input and possible adverse environmental impact of applying the agent during plant growth. Among different seed treatment methods, the simple and easy-to-operate seed coating technology is an important way to improve seed vigor, realize crop seedling sowing, and cultivate strong ...
