Root-protecting biological organic fertilizer and preparation method thereof

Abstract

The invention discloses a root-protecting biological organic fertilizer and a preparation method thereof, and belongs to the technical field of microbial fermentation organic fertilizers. The root-protecting biological organic fertilizer is prepared from 40 parts by weight of mushroom residue of Pleurotus eryngii, 20 parts by weight of sphagnum moss, 20 parts by weight of chicken manure, 5 parts by weight of bone meal, 10 parts by weight of soybean meal, 2 parts by weight of 1# composite microbial inoculant and 2 parts by weight of 2# composite microbial inoculants by a two-time fermentation process. The root-protecting biological organic fertilizer has water and fertilizer retention capacity and stable physical and chemical properties, can be directly used as a crop base fertilizer in the dosage of 250-350 kg per mu, can obviously improve the physical and chemical properties of soil, and has the effects of phosphate degradation, potassium degradation, nitrogen fixation, and improvement of the fertilizer utilization rate; by metabolism of beneficial microbes in the organic fertilizer, natural plant hormones are produced to stimulate root system growth and enhance the ability of plant disease resistance; the root-protecting biological organic fertilizer can reduce soil disease pests, and especially has a significant prevention and control effect on crop root knot nematode disease, and the nematode reduction rate can reach 70%.

Description

technical field [0001] The invention discloses a root-mulching bio-organic fertilizer and a preparation method thereof, belonging to the technical field of microbial fermentation to manufacture bio-organic fertilizers. Background technique [0002] In recent decades, with the continuous growth of the economy, people have higher and higher requirements for agricultural output. In order to meet people's desire for high yield of food and vegetables, a large amount of pesticides and chemical fertilizers have been invested. The high input of chemical fertilizers and pesticides in agricultural planting leads to changes in the physical, chemical and biological properties of the soil, the reduction of organic matter content, the destruction of the diversity of soil microbial flora, and the reduction of soil functions. The crops, especially vegetables and fruits, use a lot of pesticides , drug residues are relatively heavy, and for the crowd who eat pesticide residues for a long time...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deterioration of the soil environment and the problems of pests and diseases, the present invention has developed a mulch bio-organic fertilizer, which can not only change the physical and chemical properties of the soil, improve fertility, but also inhibit the occurrence of soil diseases and insect pests, and has a significant control effect on root-knot nematodes
