Novel microbial seedling medium and preparation method and application thereof

Abstract

The invention provides a novel microbial seedling medium and a preparation method and application thereof. The novel microbial seedling medium is prepared from the following raw materials of microbial probiotics (having the capability of inhibiting bacteria, producing IAA (Indoleacetic Acid) and dissolving inorganic phosphorus), peat, vermiculite, pearlite, mushroom residue, composted chicken manure and water. No any chemical pesticide or fertilizer are added in the novel microbial seedling medium, and the environment is not polluted. The novel microbial seedling medium disclosed by the invention has the advantages that soil can be improved, the fertilizer efficiency can be increased, the soil of the root of a plant is enabled to be fluffy and not to harden, water retention and fertilizer retention are realized, and healthy and strong growth of the root is promoted; the novel microbial seedling medium enables vegetables to be tidy and strong in seedlings, deep green in leaves, developed in root system, loosened in texture, good in air permeability, good in root development, comprehensive in nutrition, high in yield and light in pest and disease damage, and the novel microbial seedling medium is an ideal medium for producing green and organic vegetables.

Description

technical field [0001] The invention belongs to the field of microbial fertilizers, and in particular relates to a novel microbial seedling-raising substrate and a preparation method and application thereof. Background technique [0002] With the improvement of people's living standards and the enhancement of environmental protection awareness, in the international or domestic market, the access system is implemented for vegetable products, and the vegetables to enter the market must be pollution-free vegetables. The substrate is an important component material of the vegetable factory seedling raising system. It is not only the place where the seedlings live, but also the medium for the water, nutrients, and temperature required by the seedlings. Substrate, like soil, has the basic functions of supporting and nourishing crops, but it is different from soil, and even better than soil in some aspects. Therefore, the study of the physical and chemical properties of the substr...

AI Technical Summary

Problems solved by technology

[0003] A large amount of chemical nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer applied to the soil will lead to the accumulation of heavy metals in the soil, a large consumption of resources and energy, and environmental pollution, and its utilization rate is low. Resources, soil and air have caused serious pollution, causing the toxic substances in agricultural and livestock products to exceed the standard, which has brought great harm to human health. At the same time, the long-term and large-scale application of chemical fertilizers has destroyed the soil aggregate structure, resulting in soil compaction and reduced fertility.

[0004] At present, although huge manpower and material resources have been invested in microbial pesticides and microbial fertilizers at home and abroad, chemical pesticides and fertilizers are far more than biological pesticides and fertilizers in terms of quantity; in addition, biological pesticides and fertilizers have higher environmental requirements. high
