Embodiment 1
[0018] A substrate for vegetable seedling raising or cultivation, raw materials in the following volume ratio: 55% of wood bran and fermented alcohol residue, 35% of peat, 0.5% of nitrogen, phosphorus and potassium three-element compound fertilizer, and 9.5% of perlite.
[0019] The preparation method of the substrate of this vegetable seedling cultivation or cultivation:
[0020] 1) Fermentation of wood bran and alcohol residue:
[0021] a. Mix wood bran and alcohol residue in a volume ratio of 0.75-1.5:1, and add water to make the water content 40-60;
[0022] b. Add 15-35kg / m to the above mixture 3 Chicken manure and 5-10% filter mud, then add 0.1-0.25% organic material decomposing agent, pile up and ferment, when the central temperature rises to 50-70°C, keep it for 20-30 days, and turn the pile every 4-5 days during the period , so that the water content is reduced to below 30%, the material becomes soft, the color turns brown, and after the fermentation is completed, w...

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 ...
