I. Cultivation points
1. Cultivation temperature. According to the growth temperature range of shaggy mushroom, generally fall cultivation is mainly in May-August, seeding, mushrooming in late September to November, and mushrooming can still be done in March-June of the second year.
Spring cultivation is generally in January seed production, April-June mushrooms.
2. Formulation of culture material. Calculate the dosage of dry material in 100 square meters: 17500 kg of straw, 25 kg of urea, 25 kg of ammonium sulfate, 40 kg of calcium superphosphate, 75 kg of gypsum, 125 kg of vegetable cake, 50 kg of lime, and the ratio of carbon:nitrogen is 33:1.
3. Build a heap for fermentation. Choose convenient drainage, close to water, wind and sunny cement pile. Cultivation material heap system in early August, according to the 5-4-3 days type fermentation heap can be. Practice: first lay a layer of 20 cm thick, 1.5-2 meters wide pre-wetted straw, according to straw, urea, ammonium sulfate, calcium superphosphate, vegetable cake in the order of layer by layer on the heap, turn the heap three times, gypsum, lime in the second, third turn the heap in the second time to join the last turn the heap when adjusting the moisture content of about 60%.
4. Build the bed live. Digging about 0.2 meters deep, 1-1.5 meters wide mushroom beds, irrigation and penetration, 150 grams of lime powder per square meter of bed surface. Before the material on the bottom of the bed first sprinkle a layer of seed, the amount of seed about 20% of the total amount of seed, lay a layer of about 10 cm thick culture material and slightly compacted, a layer of uniformly sprinkled on the surface of the material of the seed, about 30% of the total amount of seed, and then lay a layer of about 10 cm of culture material, a little compaction, so that the total thickness of the surface of the material for the 20 cm, and then the rest of the mushroom seed using hole seeding method sown in the surface of the material under the surface, so that it is level with the surface of the material or a little lower. After sowing, the material surface leveling, compaction, mulch thickness of about 2 cm, and spray water until the mulch is wet. Thereafter covered with a layer of newspaper, a layer of film, thermometer inserted in the material surface under 10 cm to check the material temperature.
The general seeding amount is 15-25% of the dry material, should be sown in the morning and evening.
5. Germ management. Starting on the fourth day after sowing, lift the film once a day to make it ventilated, pay attention to the 10-12 cm material temperature shall not exceed 35 ℃, it is best to keep below 30%, the material temperature is too high in addition to increase the ventilation, can be lifted off the newspaper to the surface of the material in the appropriate amount of water spray to cool down, but the humidity of the air should be maintained at about 75%.
6. Mulch water. Under normal circumstances, 15-20 days after sowing, mulch surface covered with shaggy mushroom mycelium, and then mulch on its thick about 3 cm, mulch material using paddy soil or vegetable garden soil, PH value of 7 or so, the size of the soil particles of 1-2 cm, and spraying to the mulch the maximum amount of water, re-covering the newspaper, koji film, etc., so that it continues to develop bacteria. When you see a layer of mycelium on the mulch, lift the newspaper, increase ventilation and relative air humidity and light in the shed to promote good growth of mycelium.
II. Mushroom management
1. Good ventilation is one of the important characteristics of shaggy mushroom. When the temperature is low, the mushroom should be ventilated from 9 to 15 every day. If the temperature difference is big (such as in October), the mushroom can be ventilated by opening the vent at night or lifting the membrane.
2. Temperature and humidity. The mushroom stage requires the relative air humidity in the shed to be about 80%-90%, and the optimal temperature is about 20℃. The way to increase the humidity is to water the ground, spray water on the wall, spray in the air and so on, but not directly to the mushroom bed water or spray water to the substrate.
3. Light. The light required for the growth of chicken leg mushroom substrate in six yin and four yang conditions of growth is better, with the enhancement of light, the substrate aging speed is relatively faster, the color change is also big.
Third, post-harvest management
1. Harvesting period. When the fruiting body grows to seven minutes ripe, hand pinch the upper part is not soft, no gaps, no scales roll phenomenon, part of the cap is smooth white or very few brown spots, this time need to be timely harvesting.
2. Harvesting method. Chicken leg mushroom harvesting, to even "root" pull up, can not cut off the mushroom feet to stay in the mulch or on the substrate. When harvesting, hold the mushroom stalk, rotate and pull it up, then clean up the soil and sundry mushroom feet, that is, the primary commercial mushrooms.
3. Post-harvest management. After harvesting, tidy up the bed surface in time, make up the soil and level the depression, according to the dry and wet condition, pour about 2-5 kg of fertilizer solution per square meter of bed surface. Fertilizer solution formula: per 100 kg of water add urea, potassium dihydrogen phosphate 1 kg each, brown sugar 0.5 kg, fully stirred and dissolved can be used.
Chicken leg mushrooms can be harvested 3-4 tides of fresh mushrooms per feeding cultivation, and the general bio-efficiency is 100%-150%
