Abstract
The invention relates to a seed dressing agent comprising streptomyces albus, and relates to a preparation method and application of the seed dressing agent, which belong to the technical field of biological preparations. The biological seed dressing agent is prepared from the following raw materials in parts by weight: 50 to 80 parts of streptomyces albus, 1 to 4 parts of potassium fulvate, 0.1 to 4 parts of sophora alopecuroide alkaloid, 1 to 5 parts of agglutinant, 1 to 5 parts of wetting agent, 1 to 5 parts of dispersing agent, and 0.1 to 4 parts of defoaming agent; and a preservation number of the streptomyces albus is CGMCC No. 15117, and a viable count is greater than or equal to 8*1010cfu/g. The seed dressing agent can be used for promoting the plant growth, accelerating the seed germination, improving the low temperature resistance of plants, or for simultaneously accelerating the seed germination and plant growth and improving the plant disease resistance.
Description
technical field [0001] The invention relates to a biological seed dressing agent, in particular to a seed dressing agent containing Streptomyces albicans, and to a preparation method and application of the seed dressing agent, belonging to the technical field of biological preparations. Background technique [0002] "Prevention first, combining prevention and control" is the plant protection policy that our country has always adhered to. The use of seed dressings can prevent seedling diseases and systemic diseases, increase the germination rate of seeds, promote the healthy growth of seedlings, and finally achieve the functions of preventing and controlling diseases, maintaining seedlings and strengthening seedlings, and improving crop quality and yield. The seed dressing agent is economical and convenient, and has high utilization efficiency, which guarantees the protection of seedlings and seedlings. It also reduces the use of chemical pesticides at the seedling stage. ...
