Bio-organic fertilizer with shrimp shell powder as main material, and preparation method thereof

Abstract

The invention discloses a bio-organic fertilizer with shrimp shell powder as a main material. The bio-organic fertilizer is composed of, by weight, 57-60 parts of the shrimp shell powder, 10-12 parts of urea, 8-10 parts of jatropha leaf powder, 1-2 parts of distillers' grains, 20-23 parts of slaughter scraps, 6-8 parts of rape seed cakes, 2-3 parts of esliptae herba, 2-3 parts of sesbania, 4-5 parts of stevia rebaudiana, 1-2 parts of corundum powder, 3-4 parts of ditch mud, 6-7 parts of pepper stalk powder, 55-60 parts of swill, 9-13 parts of brown sugar and 72-80 parts of faeces of human and animals. The bio-organic fertilizer produced by the method has high organic matter content, and can improve soil quality and soil structure, thereby keeping ecological balance. Besides, the bio-organic fertilizer is comprehensive in nutrition and contains macroelements and microelements required by crops and a large amount of active substances produced during a microbial fermentation process.

Description

technical field [0001] The invention mainly relates to a bio-organic fertilizer with shrimp shell powder as the main ingredient, belonging to the field of fertilizers. Background technique [0002] The large and long-term use of chemical fertilizers in agricultural planting in my country has led to the lack of organic matter in the soil, the imbalance of nitrogen, phosphorus, and potassium, and the seriousness of agricultural diseases and insect pests. Excessive use of chemical fertilizers not only causes a large amount of energy consumption, but also causes agricultural water sources and soil environmental pollution. It will also cause soil compaction, reduce crop production, damage the ecological environment, and cause eutrophication of water bodies, affecting the health of humans and animals, etc.; [0003] Therefore, the mass production and use of bio-organic fertilizers produced by agricultural product production and processing waste will return the nutrients absorbe...
