Vegetable substrate nutritional soil and preparing method thereof

Abstract

The invention discloses vegetable substrate nutritional soil and a preparing method thereof. The vegetable substrate nutritional soil is prepared from corn straws, soybean curd residues, edible mushroom waste, chicken manure, river sand, river sludge, coal residues, pig bones, urea, wood shavings, pig manure, diatomite, traditional Chinese medicine residues, peanut shells, wheat straws, soybean straws, a microbial fermentation agent and agar liquid by the following steps: putting the microbial fermentation agent into the agar liquid to cultivate; putting the chicken manure and the pig manure into the edible mushroom waste to perform fermentation cultivation; grinding and mixing the corn straws, the coal residues, the pig bones, the wood shavings, the diatomite, the peanut shells, the wheat straws and the soybean straws; mixing the soybean curd residues, the river sand, the river sludge and the traditional Chinese medicine residues; adding the microbial fermentation agent and performing fermentation; adding other raw materials and performing fermentation again. The raw materials are obtained locally and cheap, have low cost and high buffer capability, avoid contradiction between water, nutrient and supplied oxygen, can be repeatedly recycled, and avoid environmental pollution residues.

Description

technical field [0001] The invention relates to the field of poultry feed, in particular to vegetable matrix nutrient soil and a preparation method thereof. Background technique [0002] The traditional cultivation of vegetables is mainly based on open-field soil cultivation. With the advancement of science and technology, soilless cultivation techniques in facilities are gradually developed and applied, such as hydroponics, aeroponics, and substrate cultivation. The disadvantage of soil cultivation is that it is very prone to continuous cropping obstacles and diseases. Other soilless cultivations are complicated in operation technology, difficult to master the matrix material preparation technology, high in cost, and difficult to meet the production needs of the applied matrix materials, thus restricting the development of facility agriculture. With the increase of my country's vegetable export volume and the adjustment of the agricultural industrial structure, protected ho...

Problems solved by technology

However, with the acceleration of the urbanization process, the urban population is gradually increasing, and the area of ​​cultivated land is decreasing. The soil of the existing cultivated land lacks nutrients, and there are more and more various chemical wastes in agriculture, which greatly pollute the soil. In terms of cultivation substrates, etc., the cost of cultivation substrates is relatively high, and the fertilizer efficiency is not ideal.
