Problems solved by technology

Application of chemical fertilizers increases heavy metals and other toxic substances in the soil
[0004] At present, people's methods of improving soil are mostly to increase the amount of chemical fertilizers, but the low content of soil organic matter cannot be solved, resulting in soil quality deterioration, soil surface crusting, and soil compaction. However, the content of organic matter in the cultivated land will continue to decrease, which will affect the deterioration of the cultivated land, and the water content will decrease, which will reduce the performance of water and fertilizer retention in the cultivated land. It cannot fundamentally solve the problems of soil water and fertilizer content and soil organic matter. Soil problems

preparation example Construction

[0043] The preparation method of the new auxiliary material: cutting the discarded branches into 6-8cm long branch sections, then placing them in a cracking furnace, performing incomplete cracking treatment at 660-740°C and anaerobic conditions for 85-110min, and then cooling, Obtain new excipients;

[0044] The prepared organic decomposed clinker has a relatively high nutrient content. Among them, the new auxiliary material has a rich pore structure, which on the one hand provides a good place for the proliferation of microorganisms, and on the other hand is conducive to the transmission of oxygen and enhances the growth of microorganisms. Activity, improve the metabolism and heat production capacity of microorganisms, increase the temperature of the compost body and shorten the composting cycle, the new auxiliary materials can promote the rapid rise of the temperature in the early stage of composting, increase the maximum temperature of the compost body, and shorten the initi...

Abstract

The invention discloses an environmental protection organic fertilizer, which is prepared from the following main raw materials by weight: 60-70 parts of an organic composted material, 16-19 parts ofa modified drug residue additive, 25-30 parts of modified straw biochar, and 0.5-0.7 part of trace elements. The preparation method comprises: 1, adding an organic composted material and modified straw biochar to a high-speed mixer, and uniformly mixing and stirring; 2, adding a modified drug residue additive and trace elements, and completely stirring to uniformly mix all the raw materials; 3, carrying out drying granulation. According to the present invention, by using the organic composted material as the matrix and adding the modified drug residue additive, the modified straw biochar and the trace amount of the trace elements according to the scientific ratio, the prepared organic fertilizer has characteristics of no pollution, environment protection and high efficiency, can provide effective and completely-absorbed nutrients for the growth of crops, can ensure the growth of crops, and ction for crop growth, has high use value and good application prospects.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and in particular relates to a green and environment-friendly organic fertilizer. Background technique [0002] Fertilizer is a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. One of the material basis of agricultural production. As early as the Western Zhou Dynasty, China already knew that field weeds can promote the growth of millet after they rot. "Qi Min Yao Shu" introduces in detail the method of planting green manure and the method of crop rotation between leguminous crops and gramineous crops; it also mentions the method of using crop stalks mixed with cow dung and urine, trampling and composting to make fertilizer . my country is a large agricultural production country. With the high utilization of fertilizers, the requirements for fertilizers are constantly increasing. At present, a large a...
