Microbial organic fertilizer and preparation method thereof

Abstract

The invention discloses a microbial organic fertilizer and a preparation method thereof, and relates to a microbial organic fertilizer prepared from plants, manure and rice husk ash and a preparation method thereof. The microbial organic fertilizer is prepared from 25 to 50 percent of residue after plant extraction, 20 to 40 percent of stalk, 10 to 40 percent of manure, 0.5 to 8 percent of organic materials starter and 10 to 40 percent of rice husk ash. The preparation method comprises the following steps of: mixing the residue after the plant extraction, crushed stalk and the manure, and adding the organic material starter, uniformly mixing, putting the mixture into a fermenting tank for high-temperature aerobic fermentation, uniformly mixing the fermented material and the rice husk ash, crushing and drying. The microbial organic fertilizer has the advantages of complete nutrient elements, lasting fertilizer efficiency, high fertilizer utilization rate, improvement of soil structure, small environmental pollution, and improvement of crop quality, and is suitable for all grain crops, vegetables, melons and fruits, flowers and grass, fruit trees, forest, tobacco, greenhouses, plastic tents and the like.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a bio-organic fertilizer for plants, poultry manure and chaff ash and a preparation method thereof. Background technique [0002] Fertilizers are the food of crops, and rational application of fertilizers is one of the important factors to ensure high and stable crop yields and promote the rapid development of my country's agriculture. Fertilizers are mainly divided into inorganic fertilizers and organic fertilizers. Inorganic fertilizers are also called chemical fertilizers, such as nitrogen fertilizers, phosphorus fertilizers, and potassium fertilizers. In modern agriculture, due to the pursuit of high agricultural yields, a large number of chemical fertilizers and pesticides are used. When these chemicals are applied to the soil, the physical, chemical and biochemical properties of the soil deteriorate sharply, the soil hardens, the microorganisms are eliminated, the lo...

Problems solved by technology

But at present, the organic fertilizer used in our country is mainly farmyard manure, that is, it is made by fermenting human, livestock and poultry manure and mounds of farmers. The quantity is small, the organic matter and nutrient content in the fertilizer are not high, and the number of beneficial microorganisms is small.
