Bag planting technique of Lentinus edodes

1. Select good and strong strains. At present, the varieties suitable for bag cultivation of Lentinus edodes are 33, Cr02, Cr04, 868, Shenxiang 2 and Huagu 939. Select white hyphae, villous, climbing, vigorous growth, low age, no antagonistic line, no miscellaneous bacteria strains.

2. Production of bacterial sticks. The time is from mid-August to early September. Production process flow: mixing-bagging-tie mouth-sterilization-cooling-inoculation. The common formula of mushroom bag cultivation is "782011", which is 78% sawdust, 20% bran or rice bran, 1% sugar, 1% gypsum powder, and the ratio of material to water is 1:1. Two to one. 3. Sterilize and disinfect the bacteria stick after bagging and tying the mouth, and inoculate it after cooling. This step must be operated under sterile conditions to prevent contamination by miscellaneous bacteria.

3. Hair germ management. Time from mid-late August to mid-late October. (1) pile inspection: 7 - 15 days after inoculation, mycelium colonization, bacterial circle about 5 cm, pile inspection, such as contaminated bacteria rod timely cleaning or rework for reuse. (2) puncture ventilation, generally puncture 3 - 4 times. (3) Prevent bacteria burning, pay attention to ventilation and shading indoors, disperse bacteria rods when the stack temperature exceeds 40 degrees Celsius, and reduce the height of rod piles.

4. Mushroom field selection. Requirements leeward sunny, flat terrain, close to water sources, good ventilation, clean environment, few pests, generally choose rice fields, 8000 to 10000 bags per mu can be discharged.

5. Mushroom shed cover. Before taking off bags, mushroom shed shall be built, requiring "three points of sunshine and seven points of shade". The height of shade shed shall be 22 meters, and shelving shall be built in the shed. First soil preparation for the ridge, ridge width 1 meter, height 25 cm, frame height 30 cm, spacing 20 cm, shelving after the construction, in the ridge bed erection of plastic arch shed.

6, bacteria rod array, bag and color. 7 to 10 days before bag removal, the bacterial rods are arranged on a rack to allow natural color conversion; when a small amount of mushroom buds appear or have been converted into brown color, the bags can be removed; after bag removal, temperature and humidity management shall be strengthened; the film shall be removed for ventilation to promote hypha color conversion, and a layer of brown color bacterial skin shall be formed on the bacterial rods.

7, fruiting management. From late October to mid-late May of the following year. (1) When the bacteria stick turns color, artificially enlarge the temperature and humidity difference, light stimulation, etc., promote the formation of mushroom buds, cover the film tightly during the day, increase the temperature and increase the humidity. Uncovering the membrane at night stimulates the formation of primordia, and usually the mushroom buds can grow in 3 to 4 days. During the fruiting period, attention should be paid to heat preservation and moisture preservation. The temperature of the mushroom bed should be controlled at about 20 degrees Celsius and the humidity should be controlled between 85 and 90 percent. In the autumn mushroom period, too much water should not be sprayed, and the mushroom stick should be too wet, which will affect the mycelium growth and lead to the death of mushroom buds. (2) Spring fruiting, March to April temperature from low to high, mycelium growth exuberant, fruiting more, water demand increased, management requirements for water fruiting. After the water content of the bacterial rod is reduced to about 35% in autumn and winter, soaking or water injection is carried out, holes with a depth of 6 to 12 cm are punched at both ends of the bacterial rod with No.8 iron wire, the bacterial rod is put into a soaking pool, pressed by a heavy object, immersed in water for 4 to 8 hours, and taken out. Spring temperature is high, rain is much, miscellaneous bacteria breed fast, should strengthen ventilation, air humidity is maintained at about 85%, when the temperature is as high as 30 degrees Celsius or more should take cooling measures, such as thickening shade, morning and evening ventilation, space spray, etc.

8. Harvest and processing. When the mushroom fruiting body grows to 80 percent maturity, it can be harvested when it looks like a "gong edge". There are three kinds of mushroom processing methods: drying method, drying method and drying method. After drying, it is packaged and stored in different grades.
