Mixed soil nutrition medium and preparation method and application thereof

Abstract

The invention belongs to the technical field of nutrition soil preparation, and discloses a mixed soil nutrition medium and a preparation method and application thereof. The mixed soil nutrition medium is prepared by mixing soil rich in various trace elements, wormcast powder containing a large amount of crude protein and amino acid, sand grains with high water permeability and air permeability and pond sludge powder rich in various nutritional ingredients. The mixed soil nutrition medium is obtained by accurately proportioning various natural components, the growth acceleration of planted plants can be better promoted, nutrition is rich, a large amount of beneficial microbial flora is contained, the loosening and ventilation performance is high, the nutritional ingredient absorption efficiency of the planted plants is higher, residue is avoided in the planted plants, the pollution rate to the environment is reduced, water and fertilizers are retained, additives are avoided, and toxicor side effect is avoided. The mixed soil nutrition medium is simple in preparation process, convenient in process and suitable for all planting industries.

Description

technical field [0001] The invention belongs to the technical field of nutrient soil preparation, in particular to a mixed soil nutrient matrix and a preparation method and application thereof. Background technology [0002] So far, the global soil pollution is relatively serious. The large-scale use of chemical fertilizers, compound fertilizers and other compound fertilizers promotes the residual chemical components in the soil. The above residues will not only cause great damage to the growth and life cycle of crops, but also accelerate the hardening process of land used for planting. [0003] Due to the hardening and serious pollution of planting soil, many plants have a high incidence rate in the planting process, resulting in a sharp reduction in the suitable planting area of planting species, and then affecting the reduction of yield. [0004] The above problems not only lead to the presence of various residual compounds in planting products, but also affect the health of c...

Problems solved by technology

Its disadvantages are: "compressed plant cultivation substrate" simply mixes the ingredients and presses them into blocks. After the selected woody nutrients are pressed into blocks, it is difficult to provide nutrients for the cultivated plants in a short time; The standard stipulates that the content of organic fertilizer is ≥ 5%, and the content of organic fertilizer is preferably 20-25", which is impossible to achieve; and attapulgite is ordinary attapulgite that has not been modified, and the viscosity of ordinary attapulgite is relatively high. Poor, it can't act as a binder, it's just a kind of filler, and the effect of anti-scouring and water retention and drought resistance is not good
