Problems solved by technology

[0003] Seed treatment agent is a kind of pesticide used for seed surface treatment. The active ingredients are mainly insecticides or fungicides. At present, seeds are coated with seeds before planting, which can prevent and control crop pests and rodents in the seedling stage. Improving the survival rate of seedlings, etc. Many seed treatment agents and coating agents currently in production can improve seed resistance to a certain extent, but most of them focus on t

specific Embodiment 1

[0020] The formulation of the seed treatment agent in this embodiment is: 30 mg / L gibberellin, 60 mg / L proline, and 30 mg / L 6-BA.

[0021] Accurately weigh 30mg of gibberellin, 60mg of proline, and 30mg of 6-BA. First, accurately measure 70mg of film-forming agent with a graduated cylinder, add 500ml of water to fully dissolve the film-forming agent, and then add and weigh in turn after fully dissolving. Good gibberellin, proline, 6-BA, and finally dilute to 1000ml with water.

specific Embodiment 2

[0022] The formulation of the seed treatment agent in this embodiment is: 60 mg / L gibberellin, 60 mg / L proline, and 60 mg / L 6-BA.

[0023] Accurately weigh 60mg of gibberellin, 60mg of proline, and 60mg of 6-BA. First, accurately measure 70mg of film-forming agent with a graduated cylinder, add 500ml of water to fully dissolve the film-forming agent, and then add and weigh in turn after fully dissolving. Good gibberellin, proline, 6-BA, and finally dilute to 1000ml with water.

experiment example 1

[0025] This experimental example is used to study the germination effect of individual components of the seed treatment agent of the present invention on corn seeds.

[0026] The independent components of table 1 seed treatment agent treat the germination effect of corn seed

[0027]

[0028] As can be seen from Table 1, the effect of treating corn seeds with 30mg / L and 60mg / L of 6-BA is better than that of the former, and its germination rate is 4.17% higher than that without hormone treatment, and the germination index is respectively Increased by 14.12% and 13.53%, germination potential increased by 142.42% and 112.12% respectively, so the 6BA concentration range when the seed treatment agent is prepared is 30mg / L-60mg / L.

[0029] Treat corn seeds with 30mg / L and 60mg / L of gibberellin, the effect is that the former is better, the germination rate has increased by 4.17%, the germination index and germination potential have increased by 16.47% and 151.52% respectively, so ...

Abstract

The invention provides a low-temperature-resistant and drought-resistant seed treatment agent and a preparation method thereof. The formula of the low-temperature-resistant and drought-resistant seed treatment agent comprises the following components: 20-70mg of gibberellin, 50-70mg of proline and 20-70mg of 6-BA based on 1L of distilled water. The low-temperature-resistant and drought-resistant seed treatment agent has favorable low temperature resistance and drought resistance during seedling emergence stage or seedling stage of crops, and has the advantage of improving the emergence rate and germination potential of crops. The raw materials in the formula for the preparation method of the seed treatment agent are wide in source and low in price; the preparation method is simple and convenient in step; the preparation process is free from toxic and side effects on test personnel, so that the seed treatment agent is easy for large-area popularization in production. The low-temperature-resistant and drought-resistant seed treatment agent has obvious stress tolerance on stress in the seedling stage of crops under a low-temperature drought condition.

Description

technical field [0001] The invention belongs to the field of plant growth regulators, in particular to a low-temperature and drought-resistant seed treatment agent and a preparation method thereof. Background technique [0002] Low temperature and drought after planting will affect seed germination, slow down the germination process, reduce germination potential and germination rate, delay emergence and reduce seedling vigor; , so that the crops are vulnerable to low temperature damage at the seedling stage, the growth and development are affected, and the germination potential and germination rate of the seeds are significantly reduced, and the reduction in the germination potential is greater than the germination rate; when the seeds encounter low temperature after germination, the growth of plant vegetative bodies will be significantly inhibited and developmental process, the degree of inhibition increases with the prolongation of low temperature duration. Studies have sh...
