Technical Field
The invention belongs to the technical field of fungus cultivation, and particularly relates to a poplar sawdust composite culture medium suitable for hypsizigus marmoreus planting and a preparation method thereof.
Background
The edible fungus fermentation technology has been rapidly developed after the 20 th century and the 80 s, and reports on the development of edible fungus submerged fermentation and medium and small fermentation equipment are increasing day by day. Hypsizigus marmoreus is a saprophytic fungus, the duration from test tube to production and use is 184 days, the hypha spreading speed is slow, the culture period is long, and the stem of fresh mushroom is soft and not durable for storage, and the shelf life is short.
Disclosure of Invention
The invention aims to provide a poplar sawdust composite culture medium suitable for hypsizygus marmoreus planting, and solves the problems that the existing hypsizygus marmoreus hyphae is slow in spreading speed, long in culture period, soft in fresh hypsizygus marmoreus stems after fruiting, not durable in storage and short in shelf life.
The invention adopts the following technical scheme:
a poplar wood chip composite culture medium suitable for hypsizigus marmoreus planting comprises the following raw materials: the corn cob cleaning agent comprises, by weight, 27% of corn cob, 14.8% of cottonseed hull, 11.1% of bran, 20.8% of rice bran, 16.3% of poplar sawdust, 4.2% of soybean hull, 1.7% of beet pulp, 2.4% of culture soil, 1.0% of light calcium carbonate and 0.7% of calcium hydroxide.
Further, the poplar wood chips are fermented poplar wood chips.
Further, the preparation method of the poplar wood chip composite culture medium suitable for hypsizigus marmoreus planting comprises the following steps of:
s1 fermentation: accumulating and fermenting the poplar wood chips;
s2 stirring: weighing the raw materials in parts by weight and uniformly stirring to prepare a dry base;
base preparation S3: adding water into the dry medium and stirring to prepare a culture medium;
s4 bottling: filling the culture medium into a strain bottle, and sterilizing at high temperature to obtain the straw mushroom culture medium.
Further, the moisture content of the poplar chips in step S2 is 60%.
Further, the weight ratio of the dry basis to the water in the step S3 is 3: 4-4.2.
Further, in step S4, the strain bottle has a capacity of 1400cc and a filling amount of 1030 and 1070 g/bottle.
Further, the high temperature sterilization in step S4 is to place in a 100-120 ℃ sterilization pot for sterilization.
The invention has the advantages that: the invention provides a poplar sawdust composite culture medium suitable for hypsizigus marmoreus planting, which is rich in nutrition and suitable in carbon-nitrogen ratio; through accumulation and fermentation of poplar chips, the physical and chemical indexes of the sawdust before use reach uniformity, the sawdust with stable quality is used, various physical and chemical indexes of a culture medium for cultivating hypsizigus marmoreus also tend to be stable, the poplar chips enable the stems of fresh hypsizigus marmoreus to be crisp and hard and to be stored for a long time, the shelf life is long, and the poplar chips are wide in source, low in price, high in lignin content and capable of being supplied throughout the year in the industrial planting process in the northeast of China.
