preparation example Construction

[0027] The preparation method of described coating agent comprises the steps:

[0028] The first step is to add the Sinorhizobium meliloti into the water, stir evenly, and obtain material A;

[0029] The second part adds the urea, the monoammonium phosphate and the polyaspartic acid into the material A, and continues to stir until uniform to obtain the material B;

[0030] The third step is to add the ABT root-inducing powder to the material B, and continue to stir until uniform to obtain material C;

[0031] The fourth step is to add the vinegar grains and the boric acid to the material C, and continue to stir until uniform to obtain the material D;

[0032] The fifth step is to add the water retaining agent and the desalting agent to the material D, and continue to stir until uniform to obtain the material E;

[0033] The sixth step is to add the clay powder and the talc powder to the material E, and continue to stir until uniform to obtain the material F; add the material...

Embodiment 1

[0047] The percentage by weight of each component of the coating agent is: 18% for urea, 13% for monoammonium phosphate, 11% for polyaspartic acid, 7% for Sinorhizobium meliloti, 12% for ABT rooting powder, 12% for vinegar grains 6% for desalination agent, 7% for water retaining agent, 5% for boric acid, 7% for water, 3% for clay powder, and 3% for talcum powder.

[0048] The coating agent is obtained according to the preparation method of the coating agent according to the weight percentage of each component of the coating agent.

[0049] After the alfalfa seeds are coated with the coating agent and planted, the alfalfa germination improvement rate is 11.25%, and the alfalfa yield improvement rate is 19.16%.

Embodiment 2

[0051] The percentages by weight of each component of the coating agent are: 16% for urea, 14% for monoammonium phosphate, 12% for polyaspartic acid, 8% for Sinorhizobium meliloti, 12% for ABT rooting powder, 12% for vinegar grains 8% for desalination agent, 4% for water retaining agent, 6% for boric acid, 5% for water, 3% for clay powder, and 4% for talcum powder.

[0052] The coating agent is obtained according to the preparation method of the coating agent according to the weight percentage of each component of the coating agent.

[0053] After the alfalfa seeds are coated with the coating agent and planted, the alfalfa germination improvement rate is 11.33%, and the alfalfa yield improvement rate is 19.43%.

Abstract

The invention is suitable for the technical field of plant planting in saline and alkaline land, and provides an alfalfa seed coating agent suitable for the saline and alkaline land as well as a preparation method thereof. The coating agent comprises the following components in percentage by weight: 15 to 19 percent of urea, 13 to 17 percent of monoammonium phosphate, 9 to 12 percent of polyaspartic acid, 6 to 10 percent of sinorhizobium meliloti, 9 to 12 percent of ABT rooting powder, 6 to 9 percent of vinegar residues, 5 to 9 percent of a desalting agent, 4 to 8 percent of a water-retainingagent, 4 to 7 percent of boric acid, 4 to 7 percent of water, 2 to 4 percent of argil powder and 2 to 4 percent of talcum powder. Therefore, the invention provides the alfalfa seed coating agent for the saline and alkaline land, which can increase the germination rate of the alfalfa seeds and increase the yield of the alfalfa in the saline and alkaline land.

Description

technical field [0001] The invention relates to the technical field of planting in saline-alkali land, in particular to an alfalfa seed coating agent suitable for saline-alkali land and a preparation method thereof. Background technique [0002] The area of ​​saline-alkali land in China is about 100 million hectares, which is equivalent to the area of ​​1.8 billion mu of cultivated land in China. The transformation and utilization of saline-alkali land has become the main new cultivated land resource in my country. Alfalfa is known as the "King of Grass". It not only has high yield, but also has excellent grass quality. All kinds of livestock and poultry like to eat it. , exceeding the tolerance limit of alfalfa's salt-alkaline tolerance, the yield of alfalfa is difficult to reach the normal amount. [0003] Seed coating technology is a plant protection technology widely promoted in my country in the 1990s. The coating agent contains insecticides, fungicides, compound ferti...
