Problems solved by technology

Under the influence of drainage, salt washing and irrigation, the loss of soil nitrogen is serious, and the phosphorus in the soil is easy to form insoluble phosphate. In addition, trace elements such as zinc, manganese, iron and copper are also reduced due to the high soil pH. sex
③ Poor soil physical properties
④ Soil microbial activity is inhibited by salinity, and the activity is poor
(2) Soil solution directly poisons crop cells
Although the above-mentioned saline-alkali soil improvers have a certain improvement effect on saline-alkali soil, the effect is not ideal. Due to the effect and cost factors, it cannot be used for a long time or in large quantities, or it will have a negative impact on soil sustainability after use.

Abstract

The invention discloses ecological organic biofertilizer and its preparation method and use. The ecological organic biofertilizer comprises, by weight, 10-15 parts of a mixture of nitrogenous fertilizer, phosphate fertilizer and potash fertilizer, 20-50 parts of an organic material subjected to fermentation decomposition, 15-30 parts of calcium-magnesium-silicon-potassium fertilizer and a nitrogen-fixing microorganism agent and/or a phosphate-solubilizing microorganism agent, wherein a ratio of the nitrogen-fixing microorganism agent and/or the phosphate-solubilizing microorganism agent to the ecological organic biofertilizer is in a range of 0.2-5.0%. The ecological organic biofertilizer can improve soil physical and chemical properties, improves a soil loosening degree after use and improves drought resistance and water retention capacities.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to an ecological organic biological fertilizer and its preparation method and application. Background technique [0002] Saline-alkali soil is a type of salt accumulation, which means that the pH value in the soil is not neutral, but H + or OH - The content is too high. According to the incomplete statistics of UNESCO and FAO, my country has 99.13 million hectares. [0003] Saline-alkali soil harms crop growth and hinders the development of agricultural production. (1) Salinization makes the physical and chemical properties of soil worse, and the living conditions of crops worsen, manifested in: ① relatively low soil organic matter content; ② soil nutritional conditions become poor. Under the influence of drainage, salt washing and irrigation, the loss of soil nitrogen is serious, and the phosphorus in the soil is easy to form insoluble phosphate. In addition, trace...
