The selection of mushroom spring cultivation time
The proper cultivation period is one of the keys to ensure the success of cultivation. The cultivation time is too early, the outside temperature is low, and the bacteria species are not easy to germinate; if it is too late, the color conversion can't be completed. In North China, the suitable cultivation period is from March 15 to April 5, and after mid-March, the average temperature in the outside world has risen above 13°C, which is conducive to germination and colonization. During this period, the air is dry, the number of environmental bacteria is small, and the cultivation rate is high. Second, the choice of suitable varieties To obtain high yield and quality of shiitake mushrooms, it is important to select the right variety. In North China, strains of Lentinula edodes suitable for bag cultivation in spring are 939, Wuxiang 1, Fufeng 1, L-26, and 9015. Third, mushroom cultivation technology 1. Formula 1 for sawdust: wood chips 85%, number of skins 13%, gypsum 2%, pH value 8 to 8.5, material: water = 1:0.7 to 0.9. 2 Sawdust 83%, cottonseed husk 10%, bran 5%, gypsum 2%, pH 8 to 8.5, material: water = 1:0.8 to 0.9. 2, the choice of cultivation bags spring planting mushrooms to produce fresh mushrooms, cultivation bags should choose flat width 20 to 22 cm, length 50 to 55 cm, 5 wire thickness of high-density polyethylene plastic bags. The outer bag is a high-density polyethylene plastic bag with a flat width of 22 to 24 cm, a length of 55 to 60 m and a thickness of 1.5 to 2 silk. 3, after the preparation of the sterilized material, the material should be charged immediately, so that the ingredients on the same day, the day of filling, the day of sterilization, loading should pay attention to the following questions: 1 loading material to elastic uniform; 2 Zhakou It is important to prevent air leakage; 3 clean the mouth of the bag before tying it up; 4 gently and gently to prevent it from causing a broken bag. After the material is loaded, the pan must be sterilized immediately. Sterilization is an extremely important part of mushroom cultivation. The thoroughness of sterilization directly affects the success or failure of cultivation. 4. After cooling and inoculation, the bacteria bag is transferred into the inoculation room after the heat is sterilized. When the bag temperature drops to about 35°C, the strain and the used tools are placed in the inoculation room, doors and windows are closed, and fumigation is performed for 8 to 10 hours with formaldehyde. , and then strictly inoculate as required. 5. Fungal management After inoculation, the bacteria bags are stacked in a well shape, stacking 5-10 layers, and in the first 15 days after inoculation, the temperature of the culture room should be maintained at 18°C ​​or higher, and should not exceed 28°C to facilitate the rapid germination of bacteria. Colonization. When the colony grows to 8 to 10 centimeters, one end of the outer bag can be released, and 25 days after inoculation, the outer bag is removed to perform the first puncture oxygenation. After oxygenation by puncture, the mycelial growth speeds up and the temperature of the bag rises. Attention should be paid to cooling the bulk and preventing stacking. The second puncture aeration is performed 10 days apart. Under normal circumstances, bags can be filled within 40 to 45 days after inoculation, and nodules are produced after 45 days, and the color conversion is completed by the middle of June. 6. After the bacterial bag has completed its color conversion, it will enter management in late summer in late June and will end in late August. The key to summers is to reduce the temperature of the bacteria bag as much as possible and maintain the activity of the mycelium. The following points should be noted in the management of the over-summer: 1 Keep the culturing room cool, not exceeding 30°C; 2 Keep the interior of the cultivating room dry and ventilated; 3 Forbidden direct sunlight to the bag; 4 Try to evacuate the bacilli, and the bacterium bar is △, Shaped placement, piled up no more than 4 floors, where conditions permit, using a single shelf placed better. 7, mushroom management When the maximum temperature outside the environment does not exceed 28 °C, you can soak the water mushroom. The fruiting time in North China is generally in early September, and the sheds can adopt a three-dimensional shading mode. After the summer of the seedlings, the moisture evaporates and the bacilli become hard. When the first soaking, the soaking time should be maintained for 20 to 24 hours in order to soften the fungus, so that the mushroom can be produced. Since the outside temperature is higher when the mushrooms are used, the fruiting bodies of the mushrooms grow rapidly and can be harvested every 15 to 20 days. By the end of December, the fruiting is basically over. 8, autumn harvest fruiting body of mushrooms should be harvested timely, not too early or too late, the specific harvest standard is: when the mushroom cap and stipe just separated, immediately harvest, when the mushroom weight is enough, bacteria The flesh is thick and the commodity value is high without excessive consumption of nutrients in the culture medium. Fourth, increase production of fertilizer by relying on growth of mushrooms, relying on nutrition, and second rely on water, so throughout the mushrooming stage, every time after fruiting must be replenishment, after the mushroom sorghum, combined with replenishment of appropriate fertilizer, for the mushroom yield is very good effect. The supplement formula is to add 0.5 kg of urea, 0.1 kg of citric acid, or 1500 to 2000 times of sage mushroom per replenishment of 200 bags of mushrooms.
