1. Reduce auxiliary materials: When you prepare mushroom formula in summer, moderately reducing the content of wheat bran and rice bran is sensible. In addition, you could increase the dosage of lime so as to lift the PH Value of substrate. And the water content in substrate should be 5% less than the situation in other season. In a word, the final purpose of this technology is to enhance the resistant ability of substrate on sundry fungus contamination.
2. Material-mixing and bagging: In high-temperature season, it is best to choose small-specification mushroom bags so that spawns quickly become fully-grown and eliminate contamination. For different mushroom varieties, mix all ingredients in accordance with respective formula, then add water and mix well. And you should note that gypsum powder and Superphosphate should be stirred well with dried substrate, then combined with water and mixed again. For urea, it is proper to dissolve it into water and then mix well with main ingredients. What’s more, stirred substrate should be bagged immediately. In case of hot weather, you could control the process from bagging to sterilization with 5 hours, or substrates are easy to turn sour or smelly, which results in output failure.
3. Sterilization: During this period, you should guarantee certain gaps between bags so that it makes for ventilation and even temperature. In the beginning of atmospheric sterilization, be sure to ensure fierce heat and raise the temperature of stove to 100 degrees within 2-4 hours. If temperature fails to rise, mushroom bags then become smelly. When temperature has been hiked to 100 degrees, maintain it for 8-12 hours on medium heat and finally, stop the heat after giving a while of high-temperature fire. In addition, it is best to add hot water halfway to sterilization stove and move bags when temperature is at 60 degrees or so, which facilitates effectively controlling sundry fungus contamination.
4. Inoculation: In hot summer, sundry fungi and harmful pests are widespread, hence the environment of inoculation should be clean, sanitary and sterilized. Cultivators should conduct airtight sterilization to inoculation house or box as well as all the tools. Besides, it is best to inoculate whenever it is not hot, the ideal arrangement is night inoculation and be sure to do it quickly with large dosage of strain and timely move inoculated mushroom bags into greenhouse for spawn-running.
