To grow mushrooms in the hot season, you need to grasp three technical aspects.
Select suitable high-temperature strains
The mushroom strains that are currently more resistant to high temperatures include Xincheng 96 and Su Mushroom No.1. The germination temperature of Xincheng 96 was 18°C-36°C, and the optimum temperature for germination was 25°C-33°C. The mushrooming temperature is 20°C-36°C, and the optimum temperature for the mushrooming is 24°C-33°C. It is the most resistant strain 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 °C -35 °C, the optimal temperature for germination is 20 °C -30 °C, the mushrooming temperature is 10 °C 35 °C, the optimum temperature for the mushroom is 15 °C -32 °C. This strain has strong viability, rapid bacterial growth, and early mushrooming. Suitable for planting in March-April and fruiting in April-July.
Put a good substrate fermentation temperature off
In the low temperature period of February-March, choose a place with a higher base temperature and a strong moisturizing effect, such as a plastic greenhouse built with 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 material temperature generally reaches 60°C-65°C on the 5th day of composting. Calculate the time from the material temperature of 60°C and turn it over for the first time after 7 days. When the material temperature drops, turn it over once every 5-6 days. When the culture material is brown, flexible, non-sticky, and odor-free, it can be inoculated.
Prevention and control of pests and diseases
The most important pests that endanger the high-temperature mushroom are mushroom mosquitoes, collembola and aphids. The diseases are walnut-like bacteria. The most effective way to control pests and diseases at the germination stage is to use pesticides and spices: every 10 kilograms of culture materials are cultivated with high-temperature edible fungi, and 10 grams of summer mushrooms and 10 grams of water are sprayed, and the plants are inoculated as they are sprayed while turning. In addition to the above measures, the following measures should also be taken:
After the soil is covered in the control of insect pests, combined with the spraying of mushroom water, the mushroom insect net insecticide 1000 times liquid and the seasoning agent 1000 times liquid are mixed in the water to control the mushrooming insect pests. 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.
Disease prevention and control The pathogenic spores of P. fulvum originate from the soil. To effectively control the disease, the soil-covered material should not be used in the field where the waste mushroom material had been applied. Instead, it should be taken out of the paddy field to clean the middle layer of soil and cracked and dried. 5 days before use, use Mushroom Fung 500 times spray, and boring after spraying for 5 days. If the color of the culture material changes, there is odor, there may be Walnut flaviform bacteria, when the determination should be promptly removed bacteria and bacteria in the soil and culture materials, and in the sick area re-spray multiple mushroom abundance 300 times liquid and mushroom strains 100 Double fluid, let it dry naturally after spraying. After 1 week, the soil is filled with water and reminder mushrooms.
