Soil improvement biofertilizer and preparation method of soil improvement biofertilizer

Abstract

The invention discloses a soil improvement biofertilizer and a preparation method of the soil improvement biofertilizer. The soil improvement biofertilizer is characterized by being prepared from the following raw materials in parts by weight: 200-350 parts of turf, 100-150 parts of clay, 5-10 parts of composite microbial agent, 5-7 parts of polyacrylamide, 60-80 parts of ammonium sulfate, 50-65 parts of monopotassium phosphate, 70-80 parts of calcium chloride, 20-25 parts of sodium borate, 15-25 parts of zinc sulfate, 20-25 parts of acetic acid, 2-3 parts of 1,2,3-glycerol, 6-10 parts of sodium gluconate, 80-100 parts of oyster shell powder and 9-12 parts of a soil conditioner. The soil conditioner contains a jade component which is beneficial to a human body by crop absorption; meanwhile, toxic heavy metal elements in soil can be effectively adsorbed and solidified; absorption of the heavy metal elements by the crops is reduced; and the crop yield can be increased. A plurality of microorganisms with the effects of fixing nitrogen, and resolving phosphor and potassium are added to the fertilizer, so that improvement of the soil structure is facilitated, and the yield and the quality of the crops are improved.

Description

technical field [0001] The invention relates to a fertilizer and a preparation method thereof, in particular to a soil-improving biological fertilizer and a preparation method thereof. Background technique [0002] With the development of my country's agriculture, the application of chemical fertilizers has become the main measure to increase agricultural production. The long-term use of chemical fertilizers such as nitrogen and phosphorus will destroy the soil structure, resulting in soil compaction, soil degradation of cultivated land, shallowing of the cultivated layer, and decline in water and fertilizer retention. The yield and quality of crops have been seriously affected; the extensive use of pesticides has caused the accumulation of pesticides in plants, which endangers the health of humans and livestock through food and feed. Therefore, effective and rational use of chemical fertilizers, reduction of pesticide application, reduction of environmental pollution, and el...
