Organic microbial compound fertilizer capable of preserving moisture and fertility

Abstract

The invention discloses organic microbial compound fertilizer capable of preserving moisture and fertility. The compound fertilizer is prepared from the following raw materials in parts by weight: 70-95 parts of thoroughly decomposed human and animal excreta, 30-42 parts of crop straw powder, 25-35 parts of rice hull ash, 20-30 parts of humic acid, 13-25 parts of peanut hulls, 11-17 parts of kieselguhr, 10-20 parts of ammonium nitrate, 4-8 parts of painite powder, 8-13 parts of zeolite powder, 12-16 parts of riverbed sludge, 4-9 parts of potassium dihydrogen phosphate, 2-10 parts of aluminum sulfate, 5-7 parts of phosphorus bacteria and 7-10 parts of microbial agent. The compound fertilizer disclosed by the invention is nontoxic, harmless and pollution-free, can comprehensively supply nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer for crops, can also supply necessary trace elements for crops, can improve the soil structure after being applied, has a stronger capability of preserving moisture and fertility, has longer fertilizer efficiency, is easily available in raw materials, is low in cost and has considerable popularization prospects.

Description

Technical field [0001] The invention relates to the field of plastics, in particular to a water- and fertilizer-retaining organic microbial compound fertilizer. Background technique [0002] At present, the world is facing serious problems of population increase and environmental degradation, and the extensive use of inorganic fertilizers in agricultural production will also make environmental degradation more serious. The main shortcomings of this inorganic fertilizer are: damage to the soil, resulting in a decrease in the content of soil organic matter, imbalance of various nutrients, soil acidification and compaction, and severe damage to the physical and chemical properties of the soil and soil microbial flora, resulting in its water retention and preservation. Fertilizer and air permeability are poor, and it is difficult to meet the actual growth needs of crops; crops are highly dependent on chemical fertilizers and pesticides, and the amount of use must be increased year by...

AI Technical Summary

Problems solved by technology

The deficiencies of this inorganic fertilizer mainly include: destroying the soil, resulting in a decrease in the content of soil organic matter, an imbalance in the proportion of various nutrients, acidification and compaction of the soil, and serious damage to the physical and chemical properties of the soil and soil microbial flora, resulting in its water retention. Fertilizer and air permeability are poor, which is difficult to meet the actual growth needs of crops; crops are highly dependent on chemical fertilizers and pesticides, and the amount of use must be increased year by year; After farmland, the actual utilization rate is only 30% on average, and most of it flows into rivers and lakes with farmland drainage or remains in the soil, plants and crops, which not only brings environmental pollution but also endangers the safety and health of human beings and lives. These have become sustainable agriculture. Obstacles to sexual development; the above conditions can be improved by applying biological fertilizers, but there are many varieties of biological fertilizers in China. The dosage is very small, it cannot be used as the main fertilizer, and the effect is single, and the price is high
