Problems solved by technology

2. Poor environmental protection, resulting in serious soil compaction
Excessive use of chemical fertilizers will deteriorate the physical and chemical properties of the soil, block the soil voids, destroy the soil aggregate structure, and cause the imbalance of soil nutrients, compaction, pollution and decline in fertility
Excessive application of chemical fertilizers also leads to groundwater pollution and air pollution, which is also a threat to human health
3. The low quality of crops directly threatens the safety of human life
[0003] At present, the quality of agricultural crops produced is not satisfactory, pesticide residues exceed the standard, chemical fertilizers are excessively applied and the utilization rate is low, vegetable nitrate accumulation is serious, heavy metal pollution, pathogenic microorganism pollution, etc. occur from time to time, which have become serious obstacles restricting crop production.

Abstract

The invention provides a crop straw decomposing agent produced by using seaweed powder to absorb a composite microbial fermentation stock solution and a preparation method thereof. The active components of the composite flora in the composite microbial fermentation stock solution include: photosynthetic bacteria, yeast, acetic acid bacteria, actinomycetes and Bacillus, the total number of strains is 0.1-1 billion / ml. After using the seaweed powder to absorb the compound bacteria and microbial fermentation stock solution, it is dehydrated by a filter press and dried at low temperature. Finally, it is made into a large amount of bacterial flora, organic acids, organic matter and trace amounts. Elemental decomposing agent for organic materials, the decomposing agent effectively increases the organic matter content of the soil, and is an ideal soil remediation agent and microbial balance agent.

Description

technical field [0001] The invention relates to a crop straw decomposing agent and its preparation method and application. The organic material decomposing agent is a decomposing agent integrating disease resistance, improving soil and increasing soil organic matter content. technical background [0002] Organic material decomposing agent (straw decomposing agent) is an organic material decomposing agent produced by modern crop nutrition and biotechnology through a special production process. It is one of the important raw materials for processing organic fertilizers. At present, for straw treatment, it is necessary to master the use of decomposing agent to deal with straw, which is an inevitable choice to increase the content of soil organic matter. With the rapid development of the chemical industry, the production and application of various chemical fertilizers have been increasing, which has played an important role in promoting the development of agricultural production...
