Problems solved by technology

In the process of strain production, conventional solid strain inoculation techniques and methods are usually used. Usually, the age difference of bag-grown shiitake mushroom strains is obvious, and the growth speed of the upper, middle and lower parts is inconsistent, and miscellaneous bacteria are easily hidden inside, which increases the pollution. , generally up to about 20%, the culture period is too long, the growth period of the strain is 40-50 days, the mycelium vigor decreases, the recovery of the strain after sowing and the ability to feed are poor, resulting in the failure of the production and cultivation link
The inoculation process is cumbersome, slow, labor-intensive and time-consuming, which affects the direct economic benefits of producers

Embodiment 1

[0016] Embodiment 1: 2500 bags of shiitake mushroom chopsticks bacterial classification production

[0017] (1) Strain culture material configuration:

[0018] 2500 bags of third-grade seeds need 25 bags of chopsticks seeds (100 pairs per bag), nutritional supplements are made of 2000g of hardwood chips, 400g of coarse wheat bran, 25g of white sugar, and 25g of gypsum, and the moisture content of the nutritional supplements is adjusted to 60%.

[0019] (2) Wooden chopsticks handling:

[0020] Make one bag per 100 pairs of wooden chopsticks (prepare 2,500 pairs of wooden chopsticks per mu or per shed), sharpen the wooden chopsticks, put the wooden chopsticks into the container, press it with a heavy object, and use 1.0 % sugar, 0.2% potassium dihydrogen phosphate and 0.1% magnesium sulfate, make a nutrient solution, soak wooden chopsticks for 12-24 hours, or boil them in nutrient solution for 20 minutes, let the wooden chopsticks fully absorb moisture, and take them out withou...

Embodiment 2

[0026] Embodiment 2: 5000 bags of shiitake mushroom chopsticks bacterial classification production

[0027] (1) Strain culture material configuration:

[0028] 5000 bags of third-grade seeds need 50 bags of chopsticks seeds (100 pairs per bag), supplementary materials are made of 3500g hardwood chips, 1300g coarse wheat bran, 50g white sugar, and 50g gypsum, and the water content of the nutritional supplementary materials is adjusted to 60%.

[0029] (2) Wooden chopsticks handling:

[0030] Use wooden chopsticks to make one bag per 100 pairs, sharpen the wooden chopsticks, put the wooden chopsticks into the container, press it with a heavy object, use 0.5% sugar, 0.2% potassium dihydrogen phosphate and 0.05% sulfuric acid Magnesium, made into a nutrient solution, soak wooden chopsticks for 12-24 hours, or boil it in nutrient solution for 20 minutes, so that the wooden chopsticks can fully absorb moisture and can be removed without dryness.

[0031] (3) Bagging treatment: acc...

Abstract

The invention relates to a bag-cultivation shiitake chopstick strain raw material formula and a production process, which relate to a bag-cultivation shiitake strain raw material formula and process for producing strains by utilization of chopsticks and belong to the field of edible fungus production. The invention aims to provide a bag-cultivation shiitake chopstick strain raw material formula which has rich sources, low cost and high survival rate, and the process for producing the bag-cultivation shiitake chopstick strains, which is simple and convenient to operate and has high strain purity and low pollution rate. The raw material formula comprises a main material and auxiliary materials by weight percentage: the main material is 100 pairs of wood chopsticks per bag; and the auxiliary materials comprise 79 to 88 percent of saw dust, 11 to 20 percent of wheat bran and 1 percent of gypsum. The process for producing the chopstick strains comprises the following steps: firstly, preparation of the raw materials; secondly, treatment of the chopsticks; thirdly, bagging treatment; fourthly, sterilization; fifthly, inoculation cultivation; and sixthly, transferring of cultivars by utilization of the shiitake chopstick strains.

Description

Technical field: [0001] The invention relates to a raw material formula of bag-grown shiitake mushroom strains and a production process for making strains by using wooden chopsticks, and belongs to the field of edible fungus production. Background technique: [0002] Lentinus edodes, also known as Lentinus edodes or Lentinus edodes, is one of the most widely planted edible fungi in the northern region. Mushroom mycelium has strong vitality and can make full use of substrate nutrition. It is suitable for a variety of raw materials. Cottonseed hulls, miscellaneous sawdust, corncobs, etc. can be used as main planting materials; cultivation auxiliary materials mainly include bran, rice bran, sucrose, and calcium carbonate. , superphosphate, etc. In the process of strain production, conventional solid strain inoculation techniques and methods are usually used. Usually, the age difference of bag-grown shiitake mushroom strains is obvious, and the growth speed of the upper, middle...
