Method for preparing tobacco floating seedling culture substrate after fermentation with Luzhou Maotai-flavor distiller's grains

Abstract

The invention discloses a method for preparing a floating seedling-raising substrate of tobacco by using Luzhou Maotai-flavored distiller's grains after fermentation, which comprises the following steps: 1) mixing Maotai-flavored distiller's grains with a moisture content of 55% to 60%, C. chinensis and rosemary Fragrant straw and lime powder are prepared into distiller's grains; 2), adding 0.1% to 0.3% decomposing bacteria to the distiller's grains and then composting and fermenting until the moisture content of the fermented material is less than or equal to 40%, to obtain fermented distiller's grains; 3 ), first air-dry the fermented distiller's grains and then pulverize them to obtain fine distiller's grains and coarse distiller's grains, mix the fine distiller's grains, coarse distiller's grains, peat, perlite, and vermiculite, add water and stir well, and then stand in a cool place for 0.5 to 1.5 hours , to obtain the tobacco floating seedling culture substrate.

Description

technical field [0001] The invention utilizes local fresh Maotai-flavor distiller's grains from Luzhou, which are fully decomposed and fermented, as the main raw material of the tobacco floating seedling-raising matrix formula, and belongs to the technical field of using agricultural waste to produce organic seedling-raising matrix. Background technique [0002] Luzhou is one of the main wine-producing areas in the country. A large amount of agricultural waste distiller's grains left after the production of wine contains high organic matter content and is rich in nutrients. However, they have high acidity and are prone to corruption. If they are not disposed of in time, they will inevitably seriously pollute the environment. . At present, my country has made some achievements in the research on the comprehensive utilization of distiller's grains, for example, using distiller's grains to cultivate edible fungi, extract compound amino acids and trace elements, make vinegar, an...

AI Technical Summary

Problems solved by technology

[0004] From the perspective of the cost of growing tobacco seedlings, the tobacco production areas generally do not produce peat, and the peat needs to be transported to the production area for a long distance. The transportation costs are expensive, which significantly increases the cost of farmers' seedling cultivation
