In order to constantly meet the requirements of mushroom growth and development on fertilization, it is generally appropriate to fertilize 4 times. Base fertilizer per mu of 1500 ~ 2000 kg of farmyard manure, calcium fertilizer 50 kg. 10-15 days after transplanting, apply the first fertilizer, 60 kilograms of ammonium bicarbonate, 50 kilograms of calcium; 30 days after transplanting, apply the second fertilizer, 60 kilograms of urea per mu, 50 kilograms of potassium sulfate. The third fertilizer is applied 45-50 days after transplanting, with 20 kg of urea per mu. Coral is used for asexual reproduction in production. A combination of field plant selection and indoor stalk selection should be used in seed selection. The number of stalks per plant is about 10 to 15, plump and neat, with the characteristics of the variety.
Indoor selection of stalks fat, an average of 40 to 50 per kilogram, no pest scars, shape in line with the characteristics of the variety, fully mature; terminal buds thick and short, transverse diameter of 0.8 cm or more, terminal buds single weight of more than 3 grams, per kilogram of terminal buds of about 340 to 350. Calculating with 3,000 plants per mu, 70~80 kilograms of plant balls are needed, and 9~10 kilograms of their terminal buds are picked; 4,000~5,000 late-water mushrooms per mu, 12~15 kilograms of terminal buds are needed. Mushroom is a rooted perennial marsh herb native to southeast China.
It prefers warm, moist and fertile soil rich in organic matter, has a long growth cycle, needs ventilation and light, and does not tolerate frost. The growth cycle is 200-210 days Cultivation of mushrooms should choose paddy fields with convenient irrigation, soil tillage layer of 20-30 centimeters, fertile soil, loose structure, loose texture, rich in organic matter, and soil ph value of slightly acidic or neutral. Cultivation of mushrooms requires careful land preparation, irrigation and deep plowing. After plowing and harrowing, blistering and basing the soil, spitting the field for about 10 days to make the soil fully mature.
The application of sufficient base fertilizer is an important measure to obtain high yield of shiitake mushrooms. Generally combined with the whole field per mu of 2000-3000 kg of farmyard manure, 15-20 kg of urea, 30-40 kg of calcium superphosphate, 25-30 kg of potassium sulfate as base fertilizer. In the growth process of shiitake mushrooms, in addition to good base fertilizer, *** can be applied three times, preferably with organic compound fertilizer to fertilize, respectively, the first time to apply before transplanting, the second time is about one month after transplanting, and the last time is in the latter half of the month.
