Preparation method of organic fertilizer for walnut saplings

Abstract

The invention discloses a preparation method of an organic fertilizer for walnut saplings. The organic fertilizer comprises the following raw materials in parts by weight: 12-20 parts of crushed cornstraw; 15-22 parts of chicken manure; 13-17 parts of cow dung; 13-21 parts of crushed legume crop straw; 3-8 parts of potassium slag and 3-8 parts of phosphorus slag; 0.5-1.2 parts of a fermenting agent; 3-6 parts of a microbial strain; several parts of human excrement. The preparation method comprises the following steps: putting crushed corn straw, chicken manure, cow dung and crushed legume crop straw into a heating chamber according to a ratio, heating the components at 80 + / - 5 DEG C for 30 + / - 5 minutes, and cooling the components to room temperature; step 2, putting the material prepared in the step 1 into a fermentation chamber, adding the fermenting agent and microbial strain in proportion, and performing sealed fermentation for 36-48 h at the fermentation temperature of 40 + / - 5DEG C; and 3, proportionally adding the potassium slag, phosphorus slag and human excrement into the material obtained in the step 2, and uniformly stirring the mixture to obtain the organic fertilizer for walnut saplings. The organic fertilizer for walnut saplings is low in production cost and comprehensive in nutrient substance, the utilization rate of the fertilizer is increased, the walnut quality is improved, the soil is improved, the environmental pollution is reduced, the physical and chemical properties of the soil can be improved, and the water retention, fertilizer retention and fertilizer supply capacities of the soil are enhanced.

Description

technical field [0001] The invention relates to the technical field of bio-organic fertilizers, and specifically discloses a method for preparing organic fertilizers for walnut saplings. Background technique [0002] Walnut is one of very nutritious nuts, and the planting area of ​​walnut saplings in my country is increasing, and the output of existing organic fertilizers for planting walnut saplings is low, which cannot meet the agricultural needs of the development of the mouth, and in the prior art Some of the planted walnut saplings contain pesticide residues, which are harmful to the health of consumers to a certain extent. In the soil with excessive application of chemical fertilizers, the content of inorganic matter soars, organic matter weakens, trace elements are unbalanced, and crop diseases and insect pests become more and more serious. A large amount of chemical fertilizers are leached into groundwater or into lakes with rainwater, causing secondary pollution to t...

Problems solved by technology

At the same time, with the rapid development of my country's livestock and poultry breeding industry in recent years, the unreasonable disposal of livestock and poultry manure has brought serious environmental pollution problems: harmful pathogenic microorganisms in livestock and poultry manure, pharmaceutical additives such as nitrogen and phosphorus, Unstable substances such as ammonia and hydrogen sulfide will be incorporated into water bodies and human bodies through different channels, thereby causing serious pollution to the atmosphere, soil and water bodies, endangering the health of local people and livestock, and bringing a series of environmental and health problems to the society

Phosphate fertilizers contain cadmium and are widely used in large quantities, which can cause serious pollution of soil, crops and food
