Corn cob planting new technology of Flammulina velutipes

1. Construct a thickened mushroom house. Choose a place where the surrounding environment is clean and sanitary, the soil layer is thick, and the soil is heavy, and the trench is 1.5 meters deep, 2 meters wide, and unlimited length. Note that the bottom of the groove is slightly narrow, the upper opening is slightly wider, and the groove wall is slightly inclined. The slopes are left at both ends to walk up and down. The bamboo is formed into a bow by a bamboo piece. The bamboo piece is covered with a plastic film. The film is made of a thick layer of 25 cm thick with straw and dead grass leaves, and then fixed with a plastic film. Thick grasses are hung on both ends of the ditch. Inject large water before use, and spray 2% dichlorvos and 5% lime solution to kill insecticide. Linyi Fertilizer Network Copyright

2. Treatment of culture materials and production of cultivation bags. Corn cobs must be fresh, dry, free of mold and insects. Special attention should be paid to old materials. After the corn cob is dried, the raw materials are pulverized by a pulverizer for use. Medium formula: corncob (or straw powder) 50 kg, urea 0.15 kg, superphosphate 0.5 kg, fat soil 2.5 kg, bran daily kg, lime 0.5 kg, gypsum 0.5 kg (post-release). Material: Water is 100:200-230. During the preparation, the urea and lime are dissolved in a sufficient amount of water, and the superphosphate is ground and mixed into the bran, the loam, the corn cob powder, and urea and lime are added while mixing. After mixing well, pile up for a long time, add 0.5 kg of gypsum before bagging and mix. The water content is based on the hand tightness and the water seeps out. The well-mixed culture material was dispensed into a 17×30 cm polypropylene bag, and each bag of dry material was about 0.5 kg. Sterilize according to conventional methods. Inoculated at one end, the variety can be selected from Flammulina velutipes No. 1, Flammulina velutipes No. 9, and Gold No. 19. After the gargle, place the bag at room temperature (if it is lower than 15 °C), pay attention to the cultivation under dark light. During the period of germination, it is necessary to check the pollution frequently and treat it in time. It is expected that the mushrooming period can be managed within 20 days.

3. Management and harvesting during the mushrooming period. Enter the mushroom bag managed during the mushrooming period. The hyphae have grown to half of the bag. Remove the cable tie at the end of the bag and relax the bag. Place it in the artificial thickened cover and place it in half or so. In case of collapse. After placing it, dry the hygrometer. The temperature is 5~20°C and the relative humidity is 70~90%. If it is slightly dry in the later stage, you can spray water into the space. For example, the conditions of temperature, humidity, carbon dioxide concentration and weak light in a microclimate environment are suitable for the growth of Flammulina velutipes, and the management is both labor-saving and quality-saving. When the mushroom handle is as long as 20 cm, it can be harvested. Linyi Fertilizer Network Copyright

When harvesting, hold the bag surface with one hand and gently pull the mushroom bush from the base with one hand. Be careful not to leave the roots and pick up the mushrooms. After the first harvest, the hyphae in the bag have been grown, and the nutrient solution is sprayed first depending on the humidity, and then the gap between the two walls and the mushroom bag or the ground is filled or sprayed. Pay attention to the temperature, humidity and mushrooming every day. After the second mushroom grows out, it will continue to be managed according to this method, and it can generally be harvested 3 to 4 times. Linyi Fertilizer Network Copyright
