Vegetable Seedling Substrate and Its Preparation and Application

Abstract

The invention belongs to vegetable seedling culture and particularly provides a vegetable seedling culture medium and preparation and application thereof. The vegetable seedling culture medium is prepared from a cotton seed hull waste mushroom material, vermiculite, a microbial quick decay agent, bio-organic fertilizer, three-element composite fertilizer and the like through the steps of raw material treatment, composting sterilization, medium compounding and the like. The technical problems that the waste mushroom material contaminates the environment, and water and soil loss is caused by the large turf use amount in the prior art are effectively solved. The vegetable seedling culture medium and preparation and application thereof have the advantages that the raw material source and the product application range are wide, the purposes of environmental protection and water and soil loss are effectively achieved, and urgent needs for sustainable development of circular agriculture and green agricultural are met.

Description

technical field [0001] The invention belongs to vegetable seedling raising, in particular to a vegetable seedling raising substrate and its preparation and application. Background technique [0002] Common commercial seedling substrates on the market are mainly composed of peat, vermiculite, perlite, organic fertilizer, and macronutrient and micronutrient fertilizers. The seedling substrate provides the rhizosphere environment such as water, fertilizer, and air required for seedling growth, determines the survival and growth of seedlings, and is the premise and foundation of crop cultivation. With the application and popularization of industrial seedling raising technology, more and more attention has been paid to seedling raising. As a non-viable mineral resource, peat is also facing the problem of less and less mining, and the mining of peat will damage the natural environment. The main ingredient of the vegetable seedling matrix formula is peat and vermiculite in a volum...

AI Technical Summary

Problems solved by technology

Farmland soil itself is relatively viscous and may contain unknown pathogenic bacteria, which is not suitable for use as a seedling substrate. Wood rot fungus chaff is the waste mushroom material after producing wood rot fungi such as shiitake mushrooms. After treatment, wood fibers are easier to degrade, rot and collapse. Different regions Different types of edible fungi are suitable for production, and the difficulty of obtaining raw materials also limits the application of different edible fungus waste materials

Another example is the vegetable seedling-growing substrate disclosed in the patent literature with the application number 201510726935.2, the selected seedling-growing substrate formula also has edible fungus bag (i.e. edible fungus waste mushroom material), but one of the prior art does not clearly indicate what kind of edible fungus to use. What kind of raw materials are used to make the edible fungus bag, which leads to certain difficulties in industrial production, and the content of active ingredients in the product is not easy to guarantee; the second is that it is also mixed with traditional Chinese medicine dregs. After the applicant's research, Chinese medicine dregs and cottonseed The contents of each nutrient component of the skin waste mushroom material are shown in Table 1

It can be seen from Table 1 that the nutrient content of traditional Chinese medicine dregs is much lower than that of cottonseed husk waste mushroom material, and there is a big difference in the use effect compared with cottonseed husk waste mushroom material
