Selenium-enriched bio-organic base fertilizer for rice planting and preparation method thereof

Abstract

The invention discloses a selenium-enriched bio-organic base fertilizer for rice planting. The selenium-enriched bio-organic base fertilizer includes 15-20 parts of chicken manure, 8-12 parts of pig manure, 10-15 parts of tea seed cake, 15-20 parts of rice bran, 6-10 parts of rice straw, 2-4 parts of vermiculite, 2-3 parts of chitosan, 4-6 parts of chaff carbon, 2-3 parts of selenium-containing substance, 4-7 of biological bacteria, 1-2 parts of azolla imbricate, 2-3 parts of nitrogen-fixing cyanobacteria, 3-5 parts of humic acid, 1-2 parts of trace elements and 5-8 parts of amino acid fertilizer. Comprehensive nutrition is provided for the growth of rice by adding animal manure and plant fibers such as agricultural waste, rice field soil hardening can be broken, the rice field soil structure is improved, rice field soil organic matter and fertility are improved, rice field drainage is facilitated, rice seedling lodging is prevented, and the selenium content in rice is effectively improved; at the same time, the biological bacteria can ferment the animal manure and the plant fibers such as the agricultural waste, so that waste is recycled, and the environment is protected.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a selenium-rich bio-organic base fertilizer for rice planting and a preparation method thereof. Background technique [0002] my country is a big agricultural country, and food cultivation is the foundation of the country. The yield and safety of rice are directly related to the survival, health and safety of the people. In recent years, in order to pursue the rapid growth of rice, chemical fertilizers and pesticides are generally used in rice planting, resulting in certain pesticide residues in the harvested rice. To a certain extent Potential hazards to human health. Therefore, the present invention, on this basis, in order to solve the above problems, provides a kind of selenium-enriched bio-organic base fertilizer for rice planting, which is sprinkled in the paddy field before the rice seedlings are planted, and after 1-2 days, the rice seedlings can be better Absorb orga...
