Problems solved by technology

The above-mentioned seed coating agents for direct-directed rice have good effects in preventing and controlling bird damage, rodent damage and improving the quality of seedlings, etc., but the above-mentioned seed coating agents have failed to solve the problem of low-temperature hazards in the emergence of direct-directed rice.
In addition, compared with the seed soaking agent, the amount of seed coating agent is large and the cost is high
So far, there is no seed soaking agent that can improve the low temperature resistance of direct seeding rice

Embodiment 1

[0031] Preparation of anti-cold seed soaking agent for direct seeding of rice:

[0032] Weigh 2 g of metalaxyl, 4 g of chloroquine, 50 mg of ABT4 type rooting powder, 50 mg of proline, 100 mg of paclobutrazol, 500 mg of calcium sulfate, 300 mg of carbofuran, and 1 g of carmine.

[0033] First use 6ml of alcohol (concentration about 50%) to fully dissolve the root powder to obtain solution I.

[0034] Then mix metalaxyl, strong chlorine, proline, paclobutrazol, calcium sulfate, carbofuran, carmine, etc. and add them to the beaker (you can also use other utensils with a smooth inner surface instead), use a glass rod (you can also use other rods) fully crushed and mixed, poured into 2L of water, and kept stirring to obtain solution II.

[0035] Add solution I to solution II, stir well and dissolve the substance, and finally obtain 2L seed soaking agent.

Embodiment 2

[0037] Preparation of anti-cold seed soaking agent for direct seeding of rice:

[0038] Weigh 1 g of metalaxyl, 3 g of chloroquine, 30 mg of indole acetic acid, 20 mg of proline, 40 mg of paclobutrazol, 102 mg of calcium nitrate, 100 mg of carbosulfan, and 100 mg of carmine.

[0039] The indole acetic acid was fully dissolved with 4 ml of alcohol (concentration about 75%) to obtain solution I.

[0040] Then mix metalaxyl, strong chlorine, proline, paclobutrazol, calcium nitrate, carbosulfan, carmine, etc. and add them to a 100ml beaker (other containers with smooth inner surfaces can also be used instead), and use a glass rod (It can also be replaced by other rods) Fully crushed and mixed, poured into 2L of clear water, and kept stirring to obtain solution II.

[0041] Add solution I to solution II, stir well and dissolve the substance, and finally obtain 2L seed soaking agent.

Embodiment 3

[0043] Preparation of anti-cold seed soaking agent for direct seeding of rice:

[0044] Weigh 3g of metalaxyl, 6g of chloroquine, 80mg of naphthaleneacetic acid, 100mg of proline, 300mg of paclobutrazol, 680mg of calcium chloride, 600mg of carbosulfan, and 2g of carmine.

[0045] First, fully dissolve the naphthaleneacetic acid with 12ml of alcohol (concentration about 99%) to obtain solution I.

[0046] Then mix metalaxyl, strong chlorine, proline, paclobutrazol, calcium chloride, carbosulfan, carmine, etc. and add them to the beaker (other containers with smooth inner surfaces can also be used instead), and use a glass rod ( It can also be replaced by other sticks) fully crushed and mixed, poured into 2L of clear water, and kept stirring to obtain solution II.

[0047] Add solution I to solution II, stir well and dissolve the substance, and finally obtain 2L seed soaking agent.

Abstract

The invention discloses a cold-resistant seed soaking agent for direct sowing of rice as well as a preparation method and applications thereof, belonging to the technical field of direct sowing of rice. The seed soaking agent comprises a cold-resistant agent, a root inducting agent and a sterilizing agent, wherein the cold-resistant agent comprises praline, paclobutrazol and calcium salts. The preparation method of the seed soaking agent comprises the following steps: adding 100-150 ml of 50-100% (weight percent concentration) ethanol to each gram of root inducting agent to dissolve the root inducting agent so as to obtain a solution I; pulverizing other components, evenly mixing, and adding the mixture into water to obtain a solution II; adding the solution I into the solution II, and continuously stirring until full dissolution and even mixing so as to prepare the cold-resistant seed soaking agent. The invention also provides the applications of the cold-resistant seed soaking agentin mechanical direct sowing, manual direct sowing, drought direct sowing or water direct sowing of rice. The seed soaking agent enhances the low temperature resistance of direct sowing rice seedlings,solves the technical problem of the popularization of the direct sowing technology in drought seasons and low temperature regions of rice and enhances the stability of the output of the direct sowingrice.

Description

technical field [0001] The invention belongs to the technical field of direct seeding of rice, and in particular relates to a cold-resistant seed soaking agent for direct directing of rice, a preparation method and application thereof. Background technique [0002] Rice direct seeding technology is popular among farmers for its advantages of reducing labor intensity and saving production costs. According to incomplete statistics, the area of ​​direct-directed rice in my country has exceeded 2 million ha. According to the law of the development of foreign rice cultivation technology with industrialization and marketization, adopting direct seeding is one of the important directions of rice cultivation in my country in the future. In developed countries such as Europe, America and Australia, since the 1970s, driven by industrialization and urbanization, almost all rice planting adopts direct seeding. At present, the area of ​​direct-directed rice in my country is also increa...
