Soil conditioner with phosphorus and potassium releasing function, and production method thereof

Abstract

The invention discloses a soil conditioner with a phosphorus and potassium releasing function. The soil conditioner is prepared from, by weight, 20-30 parts of fly ash, 60-70 parts of organic matters, 1-10 parts of Bacillus amyloliquefaciens powder with the effective live bacterium content of 19-21 billions / g, and 1-10 parts of Bacillus mucilaginosus powder with the effective live bacterium content of 9-11 billions / g. Bacillus amyloliquefaciens and Bacillus mucilaginosus are used as added microbes, and are uniformly mixed with the fly ash and the organic matterse, the obtained mixture is crushed, the crushed mixture is sieved by a 80 mesh sieve, and the obtained fine powder is dried until the water content is not greater than 30% in order to prepare the finished soil conditioner. The soil conditioner prepared through the method has soil hardening alleviating and soil permeability improving functions, also can improve the content of effective phosphorus, effective potassium and organic matters in soil, greatly improves the soil fertility, has wide application prospect, and has great economic and social benefits.

Description

technical field [0001] The invention relates to a soil conditioner and a production method thereof, in particular to a soil conditioner with functions of dissolving phosphorus and potassium and a production method thereof, belonging to the field of biotechnology. Background technique [0002] After the founding of the People's Republic of China, with the development of the chemical industry, a large amount of chemical fertilizers were applied to the land. Although it increased the production of food, it also caused damage to the soil structure, formed soil compaction, reduced the land's productive capacity, and wasted nutrients. Studies have shown that excessive application of nitrogen, phosphorus, and potassium fertilizers to the soil can destroy the aggregate structure of the soil and cause soil compaction. One of the urgent problems to be solved in agricultural production is to develop and apply new soil conditioners to improve soil compaction. [0003] Soil Conditioner ...

Problems solved by technology

However, the research and retrieval found that the main raw materials of soil conditioners currently produced in China mostly use phosphogypsum, potassium feldspar, bamboo charcoal, limestone, etc., which are costly and do not have the function of dissolving phosphorus and potassium.
