Organic nutrient soil

Abstract

The invention provides organic nutrient soil. The organic nutrient soil is prepared from, by weight, 20-30 parts of rotted leaf soil, 15-26 parts of coco coir, 12-18 parts of nanmu flour, 8-16 parts of puffing cow dung, 8-15 parts of straw ash, 6-9 parts of ground phosphate rock or calcium superphosphate, 3-7 parts of traditional Chinese medicine residues, 3-6 parts of a soil water retaining agentand 1-3 parts of a compound microbial agent. The puffing cow dung is added into the organic nutrient soil, and nutrients can be provided for plants for a long time; by adding coco coir, the soil hasthe good breathable water retaining property, by adding the compound microbial agent, growth and propagation of etiology microorganisms in the environment can be effectively restrained, and macromolecule organic matters can be decomposed into micromolecule substances capable of being absorbed by plants; the organic fertilizer and the soil water retaining agent are compounded, while organic matteris provided for soil, heavy metal ions in soil can be adsorbed, and therefore the safety risk brought by the soil heavy metal to agricultural products is lowered; the soil water retaining agent can slowly release urea molecules, and essential nutrients are provided for the soil.

Description

technical field [0001] The invention relates to the technical field of soil, and more specifically relates to an organic nutrient soil. Background technique [0002] The soil in our country is facing a huge problem. The quality of the soil directly affects the quality of the crops growing in it and the health of human beings. At present, most areas of our country rely on the application of chemical fertilizers to increase agricultural income and production, but long-term use of chemical fertilizers will cause soil organic matter and humus. Insufficient, the soil aggregate structure is destroyed, resulting in soil compaction and a decrease in the yield of agricultural plants; it may also lead to the enrichment of heavy metals in the soil, because heavy metals cannot be decomposed by soil microorganisms, and are easy to accumulate and transform into more toxic methyl compounds , thereby affecting the yield and quality of agricultural products, and some even accumulate in the h...
