Biomass organic fertilizer for improving soil aggregates

Abstract

The invention discloses a biomass organic fertilizer for improving soil aggregates. The biomass organic fertilizer is prepared from the following raw materials in parts by weight: 34-36 parts of flue-cured tobacco leaf powder, 6-7 parts of bentonite, 3-4 parts of polyaspartic acid, 5-6 parts of diammonium phosphate, 9-10 parts of wheat gluten, 2-3 parts of nickel sulfate, 3-5 parts of ferric citrate, 58-64 parts of crop straws, 75-77 parts of elodea, 2-3 parts of a cellulase preparation, 4-5 parts of a protease preparation, 7-9 parts of tamarind fruits and proper amount of water. According to the biomass organic fertilizer disclosed by the invention, biological carbon and a plurality of types of organic matters are added, so that the content of water-stable large aggregates in the soil can be improved in short time and the porosity of the soil is enhanced; bacterial agents are utilized so that a beneficial bacterium community in the soil is enriched and a micro-biological environment of the soil is improved; and the planting performance of the soil can be improved without the need of carrying out engineering modification on the soil and the additional value of the soil is improved.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a biomass organic fertilizer for improving soil aggregates. Background technique [0002] With the development of specialization, industrialization, and scale of agricultural production in my country, the requirements of agriculture for fertilizers and soil fertility have been continuously upgraded, while the extensive use of traditional inorganic fertilizers has led to deterioration of soil physical and chemical properties, and the yield, quality, and resistance of agricultural products have deteriorated. decline, restricting the sustainable development of agricultural planting. In response to the above problems, many agricultural growers choose to use organic fertilizers to improve planting conditions, but the key step in the preparation of organic fertilizers is the decomposition of refractory cellulose substances. In the structure of plant straw, cellulose is the c...

Problems solved by technology

[0003] For this reason, it is a better method to use biological enzymes to degrade plant fibers, but free biological enzymes are not stable enough under conditions such as high temperature, strong acid, strong alkali, and high ion concentration, and are easy to deactivate and reduce their catalytic ability. caused great limitations in the application

[0004] The content of aggregates in the soil affects many physical and chemical properties such as soil fertility and permeability, and has a greater impact on the growth of crops. For this reason, the inventors provide a method for immobilizing biological enzymes on biomass charcoal. Improve the stability and anti-inhibition of enzymes, and in view of the current situation that a large number of soil physical and chemical properties have relatively large defects, it provides a biomass organic fertilizer that improves soil aggregates to promote the development of the agricultural planting industry
