New method for cultivation of Flammulina

At present, the conventional cultivation method of Flammulina velutipes widely used in various places, although it can receive 3 mushrooms a year, the bioconversion rate of culture materials is only up to 100%, and each growth period is up to 95 days, and only three cultivation cycles can be recycled in one year. And the mushroom handle of the third mushroom is short and thick, easy to open the umbrella cover, and the quality of the product is poor.

According to the growth characteristics of Flammulina velutipes, a new cultivation technology for disposable culture materials was prepared. The biotransformation rate was as high as 193%, the cultivation period was shortened by 40 days, and the number of Flammulina velutipes increased, the mushroom stem increased, and the economic benefit was increased by about 80%. The technical points are as follows:

Self-made culture material: cotton husk 84%, wheat bran 14%, gypsum 1%, potassium dihydrogen phosphate 0.2%, magnesium sulfate 0.25%, carbendazim 0.55%, mix well, mix with water: 1:1.3 , Serve the culture material.

Packing disinfection The culture material is placed in a wide-mouth bottle bag. When filling, it is necessary to make the elasticity moderate to effectively avoid the phenomenon of the bottle and bag around the bottle. After filling, the bottle and bag mouth are sealed, placed in a normal temperature pot for disinfection, and cooked at a high temperature of 100 ° C for 8 to 10 hours.

After moderate temperature cultivation, after thoroughly cooling, in the inoculation room or in the inoculation box, under the flame of alcohol lamp, use the inoculating shovel to excavate the mushroom seed block from the strain bottle into the cultivation bottle and bag, and then put it into the culture room for hyphae. to cultivate. The temperature of the culture chamber must be controlled at 22 ° C ~ 26 ° C, it is strictly prohibited to pull down the long culture period to avoid the hyphae not full, the mushroom will be produced, affecting the yield and quality.

After careful management of the hyphae, you should move into the mushroom field in time, open the bottle and bag for sputum, and stimulate the mushroom. When the buds are formed, it is necessary to carry out regeneration management to promote the density of the mushroom buds, and then bagging or covering the newspapers to form a high-concentration carbon dioxide microclimate in the bottles and bags to facilitate the growth of Flammulina velutipes.

When the mushroom grows to a height of 4 to 5 cm, special attention should be paid to water management. The humidity of the cultivation site should be maintained at 80% to 90%, the temperature should be maintained at 8 °C to 14 °C, and the curtains or black plastic cloth should be used to cover the cultivation site. The light intensity can be blurred with normal vision to see the 5th Chinese character. When the mushroom grows to a height of 15 to 20 cm, it can be harvested.
