How to grow morels for high yields? A detailed guide to cultivation techniques
How can morels be grown for high yields? Please give an introduction to the cultivation methods. To achieve high yields when growing morels, you can refer to the following cultivation methods: Preparation of the substrate formula: 1. Crop straw powder 74.5%, wheat bran 20%, phosphate fertilizer 1%, gypsum 1%, lime 0.5%, humus soil 3%; 2. Sawdust 75%, wheat bran 2...
How can morels be grown for high yields? Please give an introduction to the cultivation methodsTo achieve high yields when growing morels, you can refer to the following cultivation methods:
Preparation of the substrate formula:
1. Crop straw powder 74.5%, wheat bran 20%, phosphate fertilizer 1%, gypsum 1%, lime 0.5%, humus soil 3%;
2. Sawdust 75%, wheat bran 20%, phosphate fertilizer 1%, gypsum 1%, humus soil 3%;
3. Cottonseed hulls 75%, wheat bran 20%, gypsum 1%, lime 1%, humus soil 3%. Any one of the above three can be chosen. The material-to-water ratio is 1:1.3. After mixing the materials, pile them up for fermentation for 20 days, with a moisture content of 60%. Use 17 cm x 33 cm polypropylene or polyethylene plastic bags to fill with the material, with 500-600 grams per bag, then sterilize at 100 degrees C for 8 hours, and after sterilization the spawn can be inoculated. Use the two-end inoculation method, seal the bag openings well, and place them at 22-25 degrees C to culture for about 30 days, and the mycelium can fill the bags. After the mycelium has filled the bags, let it grow fully for 5-6 days, and then cultivation can begin.
Indoor bag-removal cultivation method:
After the mushroom house is disinfected, cultivation can begin. First spread a piece of plastic film on each shelf surface, then spread a 3 cm thick layer of humus soil, flatten it, and arrange the plastic-removed mushroom logs one by one on the bed. Generally, 40 plastic mushroom bags of 17 cm x 33 cm can be arranged per 1 sq m of bed surface. After arranging the mushroom logs, lightly spray water once, then cover with soil 3-5 cm thick. After covering with soil, cover the surface with a 2 cm thick layer of bamboo leaves or broadleaf tree fallen leaves, and keep the soil moist. After 1 month, fruiting bodies can grow. Generally, in southern regions, the best mushroom emergence is between March 10 and April 20. At this time, the air humidity is 85%-90%. After morels emerge from the soil, they can grow to maturity in 7-10 days. Generally, when the color changes from dark gray to light gray or brownish yellow, they can be harvested.
Outdoor bag-removal cultivation method:
Choose woodland with light conditions of three parts sun and seven parts shade to make beds. The bed width is 1 m, the depth is 15-20 cm, and the length is unlimited. After preparing the beds, spray or lightly water once, and use 10% lime water to kill pests and miscellaneous fungi in the beds. The method of removing the bags and arranging the mushroom logs and the method of fruiting management are the same as indoor cultivation, except that no plastic film should be laid on the bottom layer. Pay attention to temperature changes in the beds and prevent direct sunlight.
Pest and disease control:
Pests and diseases can occur during both mycelial growth and fruiting body growth. Prevention should be the main approach, keeping the site environment clean and hygienic. Before sowing, carry out sterilization and insect-killing treatment on the site. If pests occur later, before fruiting bodies appear, spray pyrethrum or 10% lime water to kill pests and miscellaneous fungi.
