Efficient and environment-friendly microbial organic fertilizer and preparation method thereof

Abstract

The invention discloses efficient and environment-friendly microbial organic fertilizer. The fertilizer is prepared from raw materials as follows: kitchen waste, agricultural waste, livestock and poultry manure, waste mushroom sticks, mud from sugar refineries and beer breweries, waste from slaughter houses, ground phosphate rock, plant ash, peanut shell, traditional Chinese medicine residues, leaves and weeds, mildewed feed, a microbial agent and a leavening agent. The invention also discloses a preparation method of the fertilizer. The efficient and environment-friendly microbial organic fertilizer contains rich nutrients, can reduce disease and pest damage in soil, prevent soil hardening, provide nutrients required for growth of crops and increase the pH value, organic matter content and microbial florae of the soil after being applied, has high utilization rate and can promote absorption and conversion of crops for fertilizer and promote growth and elongation of crops. The organicfertilizer can inhibit absorption of crops for heavy metals in soil, reduce the content of heavy metals in crop products and improve the quality of crops while protecting the soil.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, in particular to an environment-friendly high-efficiency microbial organic fertilizer and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and health awareness, people attach great importance to the safety of agricultural products, and the demand for pollution-free and green food is increasing year by year, and organic food has been paid more and more attention by people. Followed by attention is ecological agriculture. Because only ecological agriculture can produce ecological food. In this regard, the state has invested a lot of support, both in terms of the strength of national policy support and in actual actions. Chemical fertilizers play a very important role in agricultural production. Chemical fertilizers account for about 50% of all productive expenditures in agricultural production, and also bring 55% of food pro...

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. barriers to sexual development

More importantly, a large amount of single inorganic fertilizers are used in the process of planting crops, resulting in soil compaction, reduced soil fertilizer supply capacity, low yield and poor quality of crops

In order to increase crop yields, farmers can only increase the input of inorganic fertilizers, which will exacerbate soil compaction, increase crop production costs, and cause soil pollution
