Humic acid containing microbial ecological fertilizer as well as preparation and application methods thereof

Abstract

The invention discloses humic acid containing microbial ecological fertilizer as well as preparation and application methods thereof. The preparation method of the humic acid containing microbial ecological fertilizer comprises following steps: an organic matter substrate is prepared and adopts humic acid particles; strains are selected and form powder through preparation; an organic coating agent is prepared: caramel pigment and water in a mass ratio being 1: (3-10) are uniformly mixed under the condition of 30-60 DEG C, and the organic coating agent is prepared; (4), 500-1,000 parts by weight of the organic matter substrate adopting the humic acid particles is uniformly coated with 1-10 parts by weight of the organic coating agent, then 2-15 parts by weight of the powder is uniformly stuck on the organic coating agent, and the humic acid containing microbial ecological fertilizer is obtained. The preparation method of the humic acid containing microbial ecological fertilizer has the advantages that microorganism death is effectively prevented and the guarantee period of the fertilizer is prolonged.

Description

technical field [0001] The invention relates to the technical field of ecological fertilizers, in particular to a humic acid microbial ecological fertilizer and a preparation and use method thereof. Background technique [0002] In recent years, a large amount of chemical fertilizers have been used in agricultural development to increase production. However, the extensive use of chemical fertilizers has gradually deteriorated the soil condition. The worse the soil, the more fertilization, and the more fertilization, the worse the soil. Fertilization and soil quality have entered a vicious cycle; soil organic matter content Problems such as decline, compaction, poor tillability, and weakened fertilizer and water retention capabilities make this a serious threat to the sustainable development of agriculture in my country. How to improve the quality of cultivated land soil has always been our concern. Soil organic carbon is an important part of cultivated soil, which plays an ex...

Problems solved by technology

Microbial ecological fertilizers have the advantages of slow decomposition and release without causing soil pollution. Microorganisms can also decompose plant residues in the soil, improve crop resistance, and release nutrients in the soil. Therefore, research on microbial ecological fertilizers has become a key to improving soil Popular, however, most of the microbial ecological fertilizers currently used in research are mixed and granulated with microorganisms, organic and inorganic fertilizers. However, microorganisms are coated in granules, and anoxic environment and excessive inorganic fertilizer content will cause some microorganisms to die. ;Because the high humidity inside the granules will also cause the microorganisms to break dormancy in advance, resulting in a large number of microorganisms multiplying, so the microorganisms enter the decay period prematurely and cause the shelf life of the fertilizer to decrease; considering that high temperature will cause the death of microorganisms, the drying process of the granules Low temperature drying, low temperature increases drying cost
