preparation example Construction

[0025] The preparation method of the selenium-enriched ecological bacterial fertilizer includes the following steps:

[0026] S1: Put rice straw, biogas slurry, shiitake mushroom residue, and compound inoculants into the mixer according to the weight ratio, and stir for 5-7 minutes. After the stirring is uniform, ferment at room temperature for 4-6 days, and then add selenite according to the weight ratio Potassium, brown sugar, ammonium carbonate, monoammonium phosphate, potassium chloride, selenium humate, and seleno-homocystine are mixed uniformly, stirred at 400-600r / min for 2-4h, granulated, and dried at room temperature to obtain compound fertilizer particles ;

[0027] The preparation method of the compound bacterial agent in step S1 includes the following steps:

[0028] a. Activate and expand the culture of Bacillus licheniformis, nitrifying bacteria, yeasts, Azotobacter sphaeroides, phosphorus bacteria, and potassium bacteria at a temperature of 22-25°C in proportions by w...

Abstract

The invention discloses selenium-enriched ecological bacterial fertilizer. The selenium-enriched ecological bacterial fertilizer is prepared from paddy rice straws, biogas slurry, mushroom residues, compound bacteria, potassium selenite, brown sugar, ammonium carbonate, monoammonium phosphate, potassium chloride, selenium humate, selenium-substituted homocystine, selenium ore powder, itaconic acid, dibutyl carboxyl toluene, a silane coupling agent KH-57, pentamethyl diethylene triamine, o-phenyl benzoic acid, polyvinyl alcohol, attapulgite, soya lecithin, sodium alginate and chitin through compound fertilizer granule preparation, coating material liquid preparation, fertilizer granule coating and drying. The ecological bacterial fertilizer can improve the yield of Chinese cabbage and the content of selenium.

Description

【Technical Field】 [0001] The invention belongs to the technical field of fertilizer preparation, and specifically relates to a selenium-enriched ecological bacterial fertilizer. 【Background technique】 [0002] Selenium is an essential trace element for the human body and an antioxidant that maintains the balance of the body. It is called a trace element that governs life. Selenium can enhance the body's immunity, prevent diabetes, cataracts and cardiovascular and cerebrovascular diseases, and also has the effects of detoxification, detoxification, prevention of liver disease and protection of the liver. When planting crops with high selenium content, it is necessary to put in fertilizers containing more selenium to increase the enrichment of selenium by the plant and realize the absorption of selenium by the body. [0003] The Chinese patent application document "A selenium-enriched liquid bacterial fertilizer and its preparation method and application (application publication num...
