High temperature mushroom cultivation three key
As temperatures rise day by day, the technical requirements for mushroom cultivation are getting higher and higher. If you want to cultivate Mushrooms in the hot season, you need to grasp the following three technical links.
First, choose the right type of high-temperature strains The mushroom strains that are more resistant to high temperatures are Xincheng 96 and Su Mushroom No.1. The temperature of Xincheng 96 fungus was 18-36°C, and the optimum temperature for germination was 25-33°C. The mushrooming temperature is 20-36°C, and the optimum temperature for the mushrooming is 24-33°C, which is the most resistant to the high temperature. The biggest advantage of this strain is that the mushroom is not discolored for 2-3 days, it is not easy to open the umbrella and it is easy to keep fresh. The disadvantage is that the speed of mycelium germination is slow, the decomposition power is weak, and the quality of the culture material is higher. It is better to plant seeds in May-June, and mushroom in June-September. Su Mushroom No. 1 germination temperature is 10-35 ° C, the optimal temperature for germination is 20-30 ° C, the mushrooming temperature is 10-35 ° C, the optimal temperature for the mushroom is 15-32 °C. This strain has strong viability, rapid bacterial growth, and early mushrooming. Suitable for planting in March-April, April-July fruiting.
Second, the good substrate fermentation temperature in the 2-3 month low temperature period, select the base temperature is higher, moisturizing effect of the place, such as plastic greenhouse built-in heap fermentation. The nutritional ratio and formula of the fermented material and the method of composting are the same as those of the autumn mushroom culture material. In order to increase the temperature of the material, the internal and external temperature difference is small. When the reactor is built, it is necessary to use a warming agent to increase the temperature. The feed temperature is generally 60-65°C on the fifth day of composting. Calculate the time from the material temperature of 60°C and turn it on for the first time after 7 days. When the material temperature drops, turn it on every 5-6 days. When the culture material is brown, flexible, non-sticky, and odor-free, it can be inoculated.
Third, prevention and control at the same time, control of pests and diseases harm The main pests of high-temperature mushrooms have mushrooms mosquitoes, collembola and aphids, the disease is walnut-like bacteria. The most effective way to control the pests and diseases during the germination period is to use pesticides and spices: Each 100 kg of culture materials with high-temperature edible fungi cultivation insecticide seasoning agent Summer Mushroom Ning 10 grams of water spray 10 kg, while spraying while turning into the bed and inoculated. In addition to the above measures, the following measures should also be taken:
(1) Prevention and control of pests. After covering the soil, combined with spraying and adjusting mushroom water, mix 1,000 times liquid of mushroom insect net insecticide and 1000 times fluid of seasoning agent in water to control the period insect pest of mushroom. When the temperature rises above 20°C, and adults of mushroom mosquitoes move on the mushroom bed, insects should be killed by insects or cypermethrin. All sides, walls and ground must be sprayed on the mushroom bed in order to effectively kill adults and reduce the number of next-generation larvae.
(2) Prevention and treatment of diseases. The pathogenic spores of the walnut fungus originate from the soil. To effectively control the disease, first, do not use the soil that has been used as a waste mushroom material in the earth-covered material. Instead, you should dig in the middle of the paddy field to clean the middle layer of soil, break it and dry it before use. 5 days with more mushrooms 500 times solution spray, spray boring after 5 days and then reuse. During the fruiting period, if there are irregular and irregular blocks of bacteria on the soil surface and the surrounding mushrooms are reduced, we must promptly open the soil surface to check the culture materials. If the color of the culture material is different, there may be different types of walnuts. When the bacteria are determined, the soil and culture materials of the bacteria should be promptly removed, and the mushroom residue should be re-emulsified in the affected area by 300 times. 100 times liquid, let it dry naturally after spraying. After 1 week, the soil is filled with water and reminder mushrooms.
