Problems solved by technology

However, the germination area of ​​the cultivars obtained by the existing cultivar medium is small after inoculation, and the germination time is long, resulting in a long production cycle of edible fungi; in addition, the production cost of the existing cultivar medium is relatively high, and the edible fungus Bag contamination rate is high

Abstract

The invention discloses a poplar segment domestic fungus cultivar culture substrate and a preparation method of the cultivar. The culture substrate is prepared by combining poplar segments, cottonseed hulls and corn flour. The nutrient composition can meet the demand of domestic fungus cultivar growth. The poplar segments are used as principle raw material which is rich in lignin, cellulose and hemicelluloses and contains less carbohydrate, improving the structure of cultivar culture substrate. The domestic fungus cultivar prepared from poplar segments has strong resistance to infectious microbe, which reduces the pollution rate of domestic fungus sacks; through the combination of poplar segments, cottonseed hulls and corn flour, the nutrition structure of the cultivar culture substrate is more abundant, the nutrition environment is more suitable for the growth of domestic fungus mycelia. After inoculation , the germination area of bacterial strain is large, the spawn running is fast and the time for spawn running cultivar fungus sack is shortened by 10 to 18 days so that the production period of domestic fungus is shortened and the annual cropping index is increased; at the same time, the method adopts poplar segments which is widely distributed as the principle raw material so that the local material can be used for reducing the production cost of domestic fungus cultivation.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a poplar section edible fungus cultivar culture material and a preparation method of the cultivar. Background technique [0002] In the existing cultivation technology of edible fungus, the culture scheme usually adopted is to adopt the multi-stage strain culture method, specifically, to prepare the mother seed culture medium first to cultivate the mother seed (first-level species) to obtain the mother seed slant (bacteria liquid) Finally, put the mother species (bacteria liquid) on the original seed medium for cultivation to obtain the original seed (secondary species), then place the original seed on the cultivation medium for cultivation to obtain the cultivated species, and cultivate Put the species into the fruiting bag or incubator, and control and adjust the process parameters of the species to obtain the fungus products. However, the germina...
