Organic-inorganic compound fertilizer capable of improving soil environment

Abstract

The invention discloses organic-inorganic compound fertilizer capable of improving a soil environment. The fertilizer is prepared from raw materials in parts by weight as follows: 20-40 parts of urea, 5-15 parts of calcium ammonium nitrate, 10-20 parts of precipitated phosphate fertilizer, 6-16 parts of monopotassium phosphate, 10-20 parts of potassium sulfate, 40-60 parts of fermented chicken manure, 5-15 parts of fermented pig manure, 2-6 parts of bamboo powder, 2-8 parts of shell powder, 10-20 parts of tapioca flour, 5-15 parts of corncobs, 4-8 parts of modified fly ash, 5-12 parts of oil shale powder, 2-4 parts of montmorillonite powder, 2-6 parts of borax, 1-2 parts of sodium silicate, 0.5-1.5 parts of ammonium molybdate, 0.4-0.9 parts of zinc carbonate, 0.1-0.8 parts of magnesium sulfate and 0.5-2 parts of sodium naphthalene acetate. The fertilizer contains very rich nutrients and can decrease the release speed of organic nutrients, effectively enhance soil fertility, effectively improve the soil structure and make hardened soil loose.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an organic-inorganic compound fertilizer for improving soil environment. Background technique [0002] At present, the fertilizers used by crops are mainly nitrogen fertilizer, fertilizer essence, potassium fertilizer and sawdust. Long-term use of chemical fertilizers will cause soil compaction, insufficient soil fertility, and various nutrient imbalances, resulting in varying degrees of damage to the farmland ecological environment and soil structure. It also affects the quality of agricultural products. Fertilization of agricultural waste with high added value is an important way to reduce agricultural pollution, save resources, and develop sustainable agriculture and circular economy. In the field of corn planting, a large number of corn cobs are produced every year, which are considerable in quantity and bulky. How to use corn cobs to prepare fertilizers, improve soil co...
