Substrate for raising or cultivating vegetable seedling and preparation method thereof

Abstract

The invention discloses a substrate for raising or cultivating vegetable seedlings and a preparation method thereof. The preparation method comprises the following steps of: adding waste sawdust and alcohol residues into plant leftover lime sludge and livestock excrement; performing pretreatment including stack retting, fermenting, air drying and sieving, wherein the substrate comprises the following raw materials in parts by volume: 40-60 parts of sawdust and alcohol residue yeast, 30-50 parts of grass carbon, 0.1-0.6 part of a nitrogen-phosphorus-potassium compound fertilizer or a urea ordinary superphosphate-diammonium phosphate chemical fertilizer, 9.75-24.45 parts of pearl stone or pelhamite, 5-10 parts of lime sludge and 0.1-0.25 part of an organic matter decomposition agent; and uniformly and fully mixing to obtain a compound substrate special for raising seedlings or cultivating. Compared with the conventional seedling raising substrate, the substrate disclosed by the invention has the advantages of saving in the grass peat resource, reduction in cost, safety, environmental friendliness, no pollution, convenience for taking raw materials, wide source and capabilities of effectively using waste, improving the seedling raising quality and increasing efficiency, and is easy to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of agricultural seedling raising or cultivation, in particular to a substrate for vegetable seedling raising or cultivation and a preparation method thereof. Background technique [0002] At present, the commonly used substrates for vegetable seedlings are composed of peat, vermiculite, perlite and other raw materials, supplemented by different ingredients, and composed of different ratios. The mining and processing of raw materials has caused great damage to the environment. At the same time, resources such as peat and vermiculite are not renewable; in addition, vermiculite and perlite are not easy to decompose, which pollutes the environment to a certain extent, and the cost of using peat is relatively high. At the same time, wastes such as cut sawdust after wood processing in the south, cassava alcohol residue from the alcohol industry, manure from animal husbandry, and filter mud from factory leftovers ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the consumption of peat in common substrate formulas and to solve the problem of utilization of waste materials such as wood chaff, alcohol residue, feces, filter mud, etc., the present invention provides a substrate for vegetable seedling raising or cultivation and its preparation method, which can not only solve the problem of wood chaff, alcohol residue, etc. slag, feces, filter mud and other waste materials, and can save peat resources and raw materials such as vermiculite
