Technical Field

the invention relates to the field of agriculture, in particular to an alfalfa drought-resistant seed coating agent.

background

alfalfa is a perennial legume, has the advantages of high protein content, rich nutrient substances and the like, and has strong growth adaptability, high hay yield and good reputation of the king of pasture. Most alfalfa planting bases in China are located in arid and semi-arid regions. Drought poses serious threat to the planting area and yield of the alfalfa, and the improvement of the drought resistance of alfalfa plants is an important means for ensuring the normal production and high yield of the alfalfa in drought areas.

At present, some methods reported in the prior art for improving the drought resistance of alfalfa can only improve the drought resistance of plants in a short time, and the drought resistance of plants needs to be treated on site, so that the requirement of large-scale production cannot be met.

Disclosure of Invention

In order to solve the problems, the invention provides an alfalfa drought-resistant seed coating agent which can improve the resistance of alfalfa, improve the rate of emergence of seeds and promote the growth of plants.

In order to achieve the purpose, the invention adopts the technical scheme that:

an alfalfa drought-resistant seed coating agent comprises the following raw materials: agricultural chitin, potassium sulfate, polyglutamic acid and attapulgite.

Preferably, the drought-resistant alfalfa seed coating agent comprises the following raw materials in parts by weight:

1-2 parts of agricultural chitin, 0.4-0.8 part of potassium sulfate, 0.01-0.015 part of polyglutamic acid and 10-15 parts of attapulgite.

Preferably, the drought-resistant alfalfa seed coating agent comprises the following raw materials in parts by weight:

1 part of agricultural chitin, 0.4 part of potassium sulfate, 0.01 part of polyglutamic acid and 10 parts of attapulgite.

Preferably, the drought-resistant alfalfa seed coating agent comprises the following raw materials in parts by weight:

2 parts of agricultural chitin, 0.8 part of potassium sulfate, 0.015 part of polyglutamic acid and 15 parts of attapulgite.

Preferably, the drought-resistant alfalfa seed coating agent comprises the following raw materials in parts by weight:

1.5 parts of agricultural chitin, 0.6 part of potassium sulfate, 0.0125 part of polyglutamic acid and 12.5 parts of attapulgite.

furthermore, the mass of the agricultural chitin in the alfalfa drought-resistant seed coating agent is 1/80-1/40 of the mass of alfalfa seeds, during coating, the weighed agricultural chitin, potassium sulfate, polyglutamic acid and attapulgite are mixed with 5-6 times of water of the mixed powder to serve as coating liquid, then the alfalfa seeds are put into a coating machine for coating treatment, and the alfalfa seeds are quickly dried after coating.

The seed coating agent of the invention can promote the absorption of nitrogen, phosphorus and potassium by seeds, promote the development of crop root systems, strengthen plant organisms, shorten the growth period of plants and enhance the disease resistance and stress resistance of plants, thereby realizing the remarkable improvement of the drought resistance of alfalfa and improving the yield.
