Abstract

The invention provides a selenium-rich bio-organic fertilizer. The selenium-rich bio-organic fertilizer is prepared from the following ingredients in parts by mass: 40-80 parts of organic residue, 0.01-0.1 part of seleniferous compound, 10-15 parts of NPK, 0.5-1 part of microbial agent and 5-10 parts of auxiliaries, wherein the microbial agent is prepared from bacillus licheniformis, paecilomyces lilacinus and bacillus amyloliquefaciens, the effective viable count ratio of the bacillus licheniformis to the paecilomyces lilacinus to the bacillus amyloliquefaciens is (1 to 100): (1 to 200): (10 to 100), and the effective viable count of the microbial agent is greater than 0.2 billion per gram. According to the selenium-rich bio-organic fertilizer, selenium and the paecilomyces lilacinus are in synergism in a reasonable proportioning ratio, and thus the nematode inhibiting effect is better; and the seleniferous compound, organic matters, the microbial agent and the auxiliaries are in synergism, so as to improve the quality and yield of crops.

Description

technical field [0001] The invention belongs to the field of fertilizers, in particular to a selenium-enriched bio-organic fertilizer. Background technique [0002] Selenium is one of the essential trace elements for humans and animals. Taking an appropriate amount of selenium can prevent some diseases. According to investigations, eating selenium-rich crops is one of the best ways to supplement selenium. Fertilizer is the grain of food. By developing selenium-enriched bio-organic fertilizer and applying selenium-enriched bio-organic fertilizer, on the one hand, it can increase the selenium content in the soil, which is beneficial to the absorption of selenium by crops, improves the quality of crops, and produces selenium-enriched agricultural products. On the other hand, biological Organic fertilizers can increase the organic matter content of the soil, optimize the ecological environment of soil microorganisms, and reduce the use of chemical fertilizers and pesticides.
