Biomass organic fertilizer capable of increasing PH of acid soil

Abstract

The invention discloses a biomass organic fertilizer capable of increasing PH of acid soil. The biomass organic fertilizer is prepared from raw materials in parts by weight as follows: 6-8 parts of seaweed meal, 2-3 parts of calcium sulfate, 2-3 parts of sodium lignin sulfonate, 28-32 parts of saw dust, 3-5 parts of monoammonium carbonate, 73-77 parts of crop straw, 15-16 parts of plant ash, 6-8 parts of attapulgite powder, 4-5 parts of lentinan, 3-4 parts of sodium nitrate, 53-57 parts of elodea nuttallii, 2-4 parts of a cellulase preparation, 3-4 parts of a protease preparation, 9-10 parts of Tamarindus indica Linn. and a proper amount of water. The biomass organic fertilizer adopts various alkaline raw materials and can reduce the content of exchangeable Al<3+> and H<+> of soil and increase the pH value of surface soil through adsorption of charcoal and activity of organic matters, so that the soil can be suitable for planting of plants, the fertility preservation potential of the soil can be improved with the aid of various nutrient materials, the fertility maintenance performance of the soil is improved, the soil is suitable for growth of plants, and the yield is increased.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a biomass organic fertilizer for improving the pH of acidic soil. 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...

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] For this reason, the present inventor provides a kind of method of immobilized biological enzyme of biomass charcoal, to improve the stability and anti-inhibition of enzyme, and aiming at the characteristics that acidic soil is not suitable for planting and low yield, a method for improving the pH of acidic soil is provided. Biomass organic fertilizers are used to promote the development of the agricultural planting industry
