Microbial seedling-growing medium and production system thereof

Abstract

The invention discloses a microbial seedling-growing medium and a production system thereof. The microbial seedling-growing medium comprises medium raw materials and water, wherein the medium raw materials comprise straw, vermiculite, a nutritional agent, coconut coir and thoroughly-decomposed cow dung, the nutritional agent and the water are added into a semi-finished medium product obtained after raw material treatment, high-temperature sterilization, raw material mixing and solid-liquid mixing are conducted, and even mixing is conducted. No chemical pesticides or fertilizers are added intothe microbial seedling-growing medium, thus the environment is not polluted, and the microbial seedling-growing medium can improve soil, improves the fertilizer efficiency, makes soil around roots ofplants loose and free from hardening, retains water and fertilizers, and promotes well growth of the roots; and by means of the microbial seedling-growing medium, vegetable seedlings can come out evenly, the seedlings are strong, leaves are dark green, root systems are strong, texture is loose, the air permeability is good, the root systems are well developed, nutrition is complete, a yield is high, and disease and pest damage is minor, so that the microbial seedling-growing medium is an idea medium for producing green and organic vegetables.

Description

technical field [0001] The invention relates to the technical field of microbial seedling cultivation, in particular to a microbial seedling cultivation substrate and a preparation system 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 substrate is of g...

Problems solved by technology

[0003] The growth of seedlings requires a large number of elements and trace elements. The large elements include nitrogen, phosphorus, and potassium, and the trace elements include boron, iron, and zinc. A certain ratio is required to avoid the imbalance of nutrients. For example, excessive nitrogen fertilizer will cause excessive growth and form Thin and weak seedlings, the chemical nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer applied to the soil in a large amount in the existing substrate will lead to the accumulation of heavy metals in the soi
