Problems solved by technology

With years of fertilization, soil compaction and acidification have accumulated, and a certain amount of heavy metal ions have accumulated, which has caused pollution in some areas and affected food safety.
Therefore, it is of great significance to study how to improve the soil and improve the nitrogen utilization rate in fertilizers. However, traditional organic fertilizer products cannot solve various pollution problems well. Therefore, it is imminent to speed up the development of environmentally friendly fertilizers.

Embodiment 1

[0022] A method for preparing environmentally friendly fertilizers from agricultural and animal husbandry waste provided by the invention comprises the following steps:

[0023] S1. Raw materials were weighed according to the weight ratio: 90 parts of crop straw, 70 parts of livestock and poultry manure, 25 parts of vermicompost, 25 parts of domestic waste, 20 parts of leaf humus, 15 parts of humic acid, 15 parts of urea, superphosphate 15 parts, 40 parts of organic fertilizer starter, of which crop straws include 50 parts of corn straw, 30 parts of wheat straw, and 10 parts of sugarcane stalks, of which, livestock and poultry manure includes 30 parts of chicken manure, 20 parts of cow manure, and 20 parts of sheep manure, Among them, the organic fertilizer starter is EM bacterial agent;

[0024] S2. Pile up poultry and livestock manure for 2 months to carry out natural ecological fermentation, degrade harmful substances and reduce their water content, and obtain fermented pou...

Embodiment 2

[0029] S1. Weigh the raw materials according to the weight ratio: 85 parts of crop straw, 75 parts of livestock and poultry manure, 30 parts of vermicompost, 30 parts of domestic waste, 23 parts of leaf humus, 18 parts of humic acid, 18 parts of urea, superphosphate 18 parts, 50 parts of organic fertilizer starter, of which crop stalks include 55 parts of corn stalks, 30 parts of wheat straw, of which, livestock manure includes 20 parts of chicken manure, 35 parts of cow manure, 15 parts of sheep manure, 5 parts of pig manure, Among them, the organic fertilizer starter is EM bacterial agent;

[0030] S2. Pile up poultry and livestock manure for 2 months to carry out natural ecological fermentation, degrade harmful substances and reduce their water content, and obtain fermented poultry and livestock manure;

[0031] S3. Dry the crop stalks in the air, control the moisture content at 30%, and then crush them into small pieces of 2 cm, pulverize the domestic waste into 100-mesh d...

Abstract

The invention discloses a method for preparing an environmental-protection fertilizer from agricultural and animal husbandry wastes, and belongs to the technical field of utilization of agricultural and animal husbandry wastes. The environmental-protection fertilizer is prepared by the steps: firstly, fermenting livestock and poultry feces, crushing crop straw, carrying out sterilization treatmenton domestic garbage and fermenting, then stirring and mixing the fermented livestock and poultry feces, the crushed crop straw, the domestic garbage fermentation material, earthworm manure and rottenleaf soil evenly, then sending the mixture into a high temperature aerobic fermentation tank, fermenting, adding a bacterial solution blended by an organic fertilizer fermentation agent, then inoculating the high-temperature aerobic fermentation tank, mixing evenly, then adding water to weighed humic acid, urea and calcium superphosphate and diluting, mixing and stirring to obtain a mixed solution, then adding to the high-temperature aerobic fermentation tank, fermenting for 20-28 days, after the fermentation is finished, drying the fermentation product at the temperature of 45-65 DEG C, drying to the moisture content of 10% or less, deodorizing, crushing to pass through a 300-400 mesh sieve, and thus obtaining the environmental-protection fertilizer. The environmental-protection fertilizer effectively utilizes the agricultural and animal husbandry wastes, has a wide range of sources, can avoid soil compaction, and has the effect of loosening soil texture.

Description

technical field [0001] The invention relates to the technical field of animal husbandry waste utilization, in particular to a method for preparing environmentally friendly fertilizers from agricultural and animal husbandry waste. Background technique [0002] The growth of crops requires a variety of nutrients. Among them, the macronutrient elements required for crop growth include carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, and the micronutrient elements include boron, copper, iron, manganese, molybdenum, zinc, and chlorine. Fertilizer is the food of crops, and the nutrients needed for crop growth must be supplemented by applying fertilizers. With years of fertilization, soil compaction and acidification have accumulated, and a certain amount of heavy metal ions have accumulated, which has caused pollution in some areas and affected food safety. Therefore, it is of great significance to study how to improve the soil and incre...
