Liquid-state composite bacterial microbe fertilizer and its preparing process

Abstract

A liquid-state compound microbial fertilizer is prepared from azotobacteria, bacillus megaterium, silicate bacteria and trace elements through physical and chemical induced mutation, mixing and diluting by water. Its advantages are high yield and quality of agricultural crops, and long quality guarantee period.

Description

Technical field: [0001] The invention belongs to the field of ecological agriculture, in particular to a liquid composite microbial fertilizer and a production method thereof. Background technique: [0002] At present, the microbial fertilizers produced by our country's bacterial fertilizer factories mainly use Azotobacter variegata, megaspore phytophytes, silicate bacteria, etc. Due to the backward production technology, the selection of bacterial culture media or carriers is unreasonable. Its ability to fix nitrogen, decompose phosphorus and potassium is low, and it is greatly fluctuated by environmental factors, so its ability to adapt to the environment is poor. At the same time, when the solid bacterial fertilizer is sprayed and used, the method is relatively cumbersome, and farmers urgently require liquid bacterial fertilizer to be launched. At present, domestic liquid bacterial fertilizers are mostly produced by direct filling of fermentation liquid and mineral oil c...

Problems solved by technology

[0002] At present, the microbial fertilizers produced by our country's bacterial fertilizer factories mainly use Azotobacter garenosa, megaspore phytophytes, silicate bacteria, etc. Due to the backward production technology, the selection of bacterial culture media or carriers is unreasonable. Its ability to fix nitrogen, decompose phosphorus and potassium is low, and it is greatly fluctuated by environmental factors, and its ability to adapt to the environment is poor

At the same time, when spraying solid bacterial fertilizer, the method is relatively cumbersome, and farmers urgently require liquid bacterial fertilizer to be launched

At present, domestic liquid bacterial fertilizers are mostly produced by direct filling of fermentation liquid and mineral oil cover technology, and the product has a short shelf life (generally about 2 months, and the standard of the Ministry of Agriculture is 6 months). The quality is unstable, and the product only contains a One or several types of effective bacteria can only meet the requirements of crops for the three major elements. At the same time, all strains have poor adaptability to the environment. When the external environment changes, the bacteria’s ability to fix nitrogen, phosphorus, and potassium will decline and cannot play a role.
