Efficient multi-functional compound bacterial fertilizer capable of quickly decomposing straws and preparation method of efficient multi-functional compound bacterial fertilizer

Abstract

The invention provides an efficient multi-functional compound bacterial fertilizer capable of quickly decomposing straws and a preparation method of the efficient multi-functional compound bacterial fertilizer. The bacterial fertilizer comprises two forms of a liquid bacterial fertilizer and a solid bacterial fertilizer, wherein the mass content of nitrogen, phosphorus and potassium in the liquid bacterial fertilizer is greater than or equal to 4%; each ml of liquid bacterial fertilizer contains 150,000,000-350,000,000 cellvibrio japonicus, pseudomonades and thermophilic sporotrichum spores, 50,000,000-250,000,000 nitrogen-fixing bacteria, phosphate-solubilizing bacteria and potassium bacteria; the mass content of nitrogen, phosphorus and potassium in the solid bacterial fertilizer is greater than or equal to 6%; each gram of solid bacterial fertilizer contains 100,000,000-250,000,000 cellvibrio japonicus, pseudomonades and thermophilic sporotrichum spores, and 50,000,000-200,000,000 nitrogen-fixing bacteria, phosphate-solubilizing bacteria and potassium bacteria. The composite bacterial fertilizer prepared from combination of multiple bacteria is capable of quickly decomposing straws at different temperatures, improving the soil structure and the soil microenvironment and increasing the soil fertility, so that the crop yield is increased and the quality of the crop is improved.

Description

technical field [0001] The invention relates to a high-efficiency multifunctional compound bacterial fertilizer for quickly decomposing straw and a preparation method thereof, belonging to the technical field of microbial compound bacterial fertilizer preparation. Background technique [0002] Crop straw is an abundant renewable resource in nature. The traditional straw returning to the field is difficult to decompose and utilize the straw in a short time, and most farmers burn the harvested straw on the spot, causing environmental pollution and waste of resources. At present, many farmers still choose inorganic chemical fertilizers to topdress crops, but long-term application of inorganic chemical fertilizers will cause soil compaction, damage the soil structure, and bring hidden dangers to crop production and income. The use of microbial fertilizers to improve soil conditions has become one of the research hotspots for sustainable agricultural development. Nowadays, a vari...

[0002] Crop straw is an abundant renewable resource in nature. The traditional straw returning to the field is difficult to decompose and utilize the straw in a short time, and most farmers burn the harvested straw on the spot, causing environmental pollution and waste of resources.

At present, many farmers still choose inorganic chemical fertilizers to topdress crops, but long-term application of inorganic chemical fertilizers will cause soil compaction, damage the soil structure, and bring hidden dangers to crop production and income.

The use of microbial fertilizers to improve soil conditions has become one of the research hotspots for sustainable agricultural development. Nowadays, a variety of microbial fertilizers have appeared in the market, but the microbial fertilizers used for decomposing straw are expensive, have single functions, and quickly decompose straw. High-efficiency and multi-functional compound bacterial fertilizer varieties are even rarer
