The central and western regions of our province are the main grain producing areas, and large areas are planted with crops such as corn and rice. This summer, the temperature is low and rainy, and the crops are poor. The majority of farmers can consider using crop straw as a base material to cultivate the big mushroom and make up for the loss caused by grain production.
The cultivation of large globus mushrooms has the following characteristics: First, the raw materials are widely sourced and the production cost is low. Use rice husks, straw, corn stalks, corn cobs, etc. as culture materials, and grow raw materials or fermented materials in greenhouses or greenhouses; second, cultivation techniques are simple, no need for production equipment and bagging, sterilization, inoculation, etc. Technical links, high success rate, low risk; Third, large ball mushroom can be freshly sold, can also be processed into dry goods or canned, the market price is stable; Fourth, the cultivation of large ball mushroom is economically efficient. The cultivation of 667 square meters of large ball mushroom is invested 15,000 yuan, and the production of fresh mushrooms is 4000 kilograms. The market price is 8-10 yuan/kg (fresh), the net profit is 15,000 yuan, and the input-output ratio is 1:2. After the fall, the temperature drops, which is suitable for the cultivation of the big ball mushroom. This article briefly introduces the cultivation techniques of the big mushroom:
Cultivation place. The cultivation of large glutinous mushrooms can use vegetable greenhouses or rice nursery sheds; it can also use greenhouses, greenhouses require good winter lighting, and have heating conditions to ensure winter mushrooming, high market prices and good economic returns.
Seasonal arrangement. The big ball mushroom is planted in autumn and in mid-September. Greenhouse cultivation began to appear in mid-November, and greenhouse cultivation began in April of the following year.
Cultivation material formula. Formula 1: 57% rice hull powder, 35% corn cob, 5% bran, 1% gypsum powder, 2% lime powder; Formula 2: 50% corn stalk, 42% corn cob, 5% bran, gypsum powder 1 %, lime powder 2%.
The mixture is piled and fermented. The corn stover was cut into a length of 30-40 cm by a mower, and the corn cob was pulverized into 0.5 cm granules. Raw materials such as corn stover, corn cob or rice husk are immersed in the pool for 2 days, and the fermentation is carried out when the water content of the raw material reaches 70%-75%. According to the formula, other raw and auxiliary materials are added, and the mixture is evenly distributed, and the pile is 1.5-2 meters wide and 1-1.5 meters high, and the length is not limited. After 3 days, the stack temperature rose to 65 ° C or more and turned over the heap, and then fermented for 3 days to sow.
Spreading and planting the soil. The layered method is used, and 1.5 bags of strains are used for 1 square meter. Generally, 3 layers of material are laid, each layer is 10 cm thick, and the strain is planted between the two layers of culture materials. The first layer of the culture material is used to sprinkle 50% of the bacteria on the surface, and the outer layer is less and less; the second layer is Sprinkle the remaining 50% of the strain on the surface, less inside and outside. The upper layer is 4-5 cm thick, covers the strain and gently presses the surface, and uses 1-25 square meters of culture material 25-30 kg, then covers the soil after covering 1-2 cm on the culture material, and covers the straw curtain on the soil.
After the big ball mushroom is sown, the shed door can be opened in the early stage, and the shed door can be insulated when the temperature is lower than 15 °C. The temperature in the shed is controlled between 21 °C and 27 °C. The water content of the culture material is controlled between 70-75%. No light is needed. During the germination period, the water content of the culture material can be increased by spraying water on the soil. After 50-60 days of spraying, you can spray water to produce mushrooms.
