Method for preparing culture medium with Chinese herbal medicine dregs

Abstract

The invention discloses a method for preparing a culture medium with Chinese herbal medicine dregs. The method comprises the steps as follows: after the Chinese herbal medicine dregs are accumulated for anaerobic fermentation, compound bacteria of bacillus subtilis and aspergillus niger as per the bacterial content are added and mixed uniformly to enable the bacterial content concentration to be higher than 500 thousands bacteria per gram, then syrup is sprayed and mixed uniformly, after accumulation, the accumulated materials are covered with a black plastic film until the highest temperature in the accumulated materials reaches 55 DEG C, the black plastic film is removed for aerobic fermentation until the moisture content of the accumulated materials is lower than 45%, and the culture medium can be obtained through accumulation and ageing. The culture medium prepared with the method is low in salinity, low in EC value, large in cation exchange capacity and high in acid-base buffering capacity and saline-alkaline buffering capacity; meanwhile, by the aid of the culture medium, the soil looseness degree, the fertilizer keeping and water holding capacity and the heat insulation and ventilation capacity can also be improved; the culture medium is suitable for most of crops, even flowers, plants and the like with very strict cultivation requirements, the culture medium is suitable for mixing with any materials to be prepared into required media without limitations, and salinization conditions caused by excessive use can be avoided.

Description

【Technical field】 [0001] The invention relates to a method for making a cultivation substrate, in particular to a method for making a cultivation substrate by using herb residues from traditional Chinese medicines, and belongs to the technical field of agricultural production. 【Background technique】 [0002] The cultivation medium originally originated from the concept of soilless cultivation, which means that the soil environment around the crops has deteriorated, seriously affecting the yield and quality of the crops, and people are looking for alternatives, using solid substrates to fix plant roots and absorb nutrient solutions through the substrates and oxygen. The so-called cultivation substrate refers to the solid medium that replaces the soil to provide mechanical support and material supply for crops. In many cases, the surrounding soil environment does not deteriorate, but people hope that the cultivation conditions will be better and the crops will grow better. ...

Referring to some patents again, the raw materials in them cover a wide range, such as agricultural and forestry wastes and garden wastes. As everyone knows, branches and leaves are so different, it is impossible for one invented method to cover everything, and the raw materials must be classified. processing, otherwise it is difficult to achieve, meaningless
