Embodiment 1

[0032] The raw material of the potato seed coating agent of the present embodiment consists of 0.5 parts by weight of composite microorganisms, 13 parts of rice soup, 0.5 parts of urea, 0.16 parts of ferrous sulfate and 75 parts of clear water. The composite microorganisms are compounded by Lactobacillus plantarum liquid, Saccharomyces cerevisiae liquid and Bacillus subtilis bacterial liquid. 23 parts of liquid and 25 parts of Bacillus subtilis liquid. The three bacterial solutions were prepared by the inventors themselves, and the bacterial solutions were obtained by fermenting and culturing Lactobacillus plantarum, Saccharomyces cerevisiae and Bacillus subtilis in corresponding liquid medium. The bacterial contents of the three single-strain bacterial liquids are respectively: the bacterial contents of Lactobacillus plantarum ≥ 3.0×10 10 cfu / mL, the bacterial content of Saccharomyces cerevisiae ≥1.0×10 9 cfu / mL, the bacterial content of Bacillus subtilis ≥5.0×10 9 cfu / mL....

The composite microorganisms are compounded by Lactobacillus plantarum liquid, Saccharomyces cerevisiae liquid and Bacillus subtilis bacterial liquid. 26 parts of liquid and 22 parts of Bacillus subtilis liquid. The three bacterial solutions were prepared by the inventors themselves, and the bacterial solutions were obtained by fermenting and culturing Lactobacillus plantarum, Saccharomyces cerevisiae and Bacillus subtilis in corresponding liquid medium. The bacterial contents of the three single-strain bacterial liquids are respectively: the bacterial contents of Lactobacillus plantarum ≥ 3.0×10 10 cfu / mL, the bacterial content of Saccharomyces cerevisiae ≥1.0×10 9 cfu / mL, the bacterial content of Bacillus subtilis ≥5.0×109 cfu / mL....

Embodiment 3

[0048] The raw material of the potato seed coating agent of the present embodiment is made up of 3.5 parts by weight of composite microorganisms, 17 parts of rice soup, 0.2 part of urea, 0.10 part of ferrous sulfate and 85 parts of clear water. The composite microorganisms are compounded by Lactobacillus plantarum liquid, Saccharomyces cerevisiae liquid and Bacillus subtilis bacterial liquid. 20 parts of liquid and 17 parts of Bacillus subtilis liquid. The three bacterial solutions were prepared by the inventors themselves, and the bacterial solutions were obtained by fermenting and culturing Lactobacillus plantarum, Saccharomyces cerevisiae and Bacillus subtilis in corresponding liquid medium. The bacterial contents of the three single-strain bacterial liquids are respectively: the bacterial contents of Lactobacillus plantarum ≥ 3.0×10 10 cfu / mL, the bacterial content of Saccharomyces cerevisiae ≥1.0×10 9 cfu / mL, the bacterial content of Bacillus subtilis ≥5.0×10 9 cfu / mL....

Abstract

The invention discloses a potato seed coating agent and a preparation method thereof. The seed coating agent disclosed by the invention is prepared from raw materials consisting of compound microorganisms, rice soup, urea, ferrous sulfate and clear water. The seed coating agent is prepared from the following raw material components in parts by weight: 0.5-5.0 parts of compound microorganisms, 10-20 parts of rice soup, 0.1-0.5 part of urea, 0.10-0.20 part of ferrous sulfate and 75-90 parts of clear water. The preparation process of the seed coating agent comprises the following steps of mixing each single bacterial liquid according to a preset weight ratio to obtain compound microorganisms, mixing the raw material components according to a preset weight ratio to obtain a mixed material, carrying out facultative fermentation on the mixed material at the temperature of 30-38 DEG C, then carrying out open standing, and ending the fermentation when the pH value of the fermented material is less than or equal to 3.8, centrifuging the fermented liquid, and collecting supernatant as a seed coating agent. The seed coating agent is used for planting potatoes, and can promote the growth of the potatoes and improve the yield and quality of the potatoes.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a potato seed coating agent and a preparation method thereof. Background technique [0002] With the development of our society, people's demand for food consumption is increasing. However, due to the influence of factors such as the natural environment, arable land area, and water resources, the cost of continuing to increase production of staple food varieties such as rice, corn, and wheat has increased, and the room for improvement has become smaller. The difficulty becomes greater. The potato has wide adaptability to the environment and a wide range of uses, and is the fourth largest food crop in the world. Planting potatoes is of great significance to my country's food security and sustainable social development, but the yield per mu of potatoes in my country is low and cannot meet the needs of people's consumption. [0003] Seed coating technology uses s...
