Problems solved by technology

[0004] In the past, sodium selenite was added to food for animal selenium supplementation, but its bioavailability is low, and the intake range (50-400μg / day) is narrow, and it is easy to cause excessive intake and poisoning
Soil application and foliar spraying of sodium selenite, due to soil fixation and a large amount of drift, not only has low selenium availability, but also has poor safety and economics, so it cannot be used as a selenium supplement measure for agricultural product production

Embodiment 1

[0010] Embodiment 1: The raw material of seed coating agent comprises: sodium sulfite, fulvic acid, effective microorganism (Em bacteria) culture, film-forming agent, protective agent. It contains 10-15% of selenium-enriched production-increasing mother liquor, 1-3% of protective agent, 40-60% of film-forming agent, and the rest is water, which is uniformly mixed and ground at normal temperature. Wherein the protective agent adopts carbendazim or thiram, the film-forming agent adds water to absorb and grind 3-8% of methylcellulose by weight, and after crushing polyethylene glycol 2-5%, it is dissolved in water greater than 60°C, and then It is prepared by adding 15-20% ethanol and 1.5-2.5% coloring agent, mixing and grinding. The seed coating agent can be used for coating seeds of wheat, corn, cotton, etc., and the ratio of drug to species is 1:30-50.

Abstract

A Se-enriched yield-increasing chemical is prepared proportionally from chicken droppings, silkworm dung, cotton seed cake or rapeseed cake, and cultured Em bacteria liquid through mixing, fermenting, adding sodium selenite and water, stirring, fermenting, filterint to obtain mother liquid, adding xanthonic acid and stirring. It can increase the Se content and yield of agricultural crops.

Description

technical field [0001] The invention belongs to a selenium-enriched biological preparation, in particular to a production method of a seed coating agent containing a selenium-enriched production-increasing factor. Background technique [0002] Selenium is an essential micronutrient for animals and humans. The recommended daily intake by the International Selenium Society is 60-400 μg, and the recommended daily intake by the Chinese Nutrition Society is 50-200 μg. According to my country's nutritional survey, the daily intake of selenium for adults is only 26-32 μg. Therefore, selenium malnutrition is a common problem in our population. my country's selenium-deficient soil accounts for 72% of the country's land area, and the selenium-deficient population reaches more than 100 million. Many endemic high-incidence diseases in my country, such as Keshan disease, Kaschin-Beck disease, cancer, cardiovascular and cerebrovascular diseases, diabetes, in...
