Application of warming agent and straw cultivation of edible fungi, know the prevention and control methods of edible fungus diseases

In recent years, with the popularization of new technology of edible fungi, the demand for cottonseed hull increases, and the price increases year by year. In order to reduce the production cost, local mushroom farmers use local materials and use their own crop straw to cultivate edible fungi. But the results are often low and unsatisfactory. Because the straw itself is hard and high in silicon, it is not suitable for the growth of edible fungi.

I used a self-made steam generator to deal with crop straw by steam softening method to solve the problems of straw hardness, heavy silicon content and unsuitable for mycelium growth. However, in the process of steam softening straw, to burn a large number of wood, coal, but also need to be taken care of, the treatment of straw is also limited.

In order to solve the above problems, I began to use temperature starter to treat crop straw last year, and achieved success. The temperature-increasing starter is a kind of biological material that can improve the stack temperature, and the temperature is uniform from the inside to the outside. Due to the large number of thermophilic microorganisms in the material, the prepared culture material is rotten and consistent, no ammonia flavor, brown, and white actinomycetes. It has the characteristics of high-quality culture materials. It is widely used in the cultivation of Pleurotus ostreatus, Coprinus comatus, Pleurotus ostreatus and Auricularia auricula, which greatly improves the biological efficiency. In addition, the heating agent is convenient, simple and low cost. There is no need to turn the pile in the process of straw treatment, which greatly reduces the consumption of manpower and material resources and reduces the production cost. I used the warming agent to treat the straw to cultivate edible fungi and achieved good benefits. The use of heating agent is introduced as follows:

The process of pre-wetting and softening of raw materials. Rice straw, wheat straw, corn stalk, distiller's grains, sawdust and so on. The raw materials are required to be dry and mildew-free. Each bundle is tied up according to 5-250 kg, and the scraps are bagged and set aside. First put the lime into the bubble pool which is 3 meters long, 1 meter wide and 0.8 meters deep, and then measure the pH value at 14:00 with the test paper to soak the above-mentioned material in lime water. Press and sink it with a heavy object, after 20 minutes, drain and place the cover film on one side, drain naturally for 2 hours, then build a pile to soften. Select the higher terrain, build the pile according to 2 meters wide, 1.5 meters high and unlimited length, cover the forage with thin film, leave a little vent at both ends and soften for 6 days.

2. Build Xiaoqu pile. The heating agent uses 1 kg of straw for every 2000 kg of straw. In the last day of softening, dry livestock and poultry manure, cake fertilizer, phosphate fertilizer or using fodder, cotton shell, sawdust and other paving materials and heating agent mixed with water to 60%, to pinch into a ball, throw away and disperse. Then build a small pile, cover it with a membrane, and ferment for 8-12 hours.

3. Mixed batch fermentation. Mix the fermented paving material with a large pile of material directly into the shed and go to bed. The thickness of the material is 50-70 cm, and the moisture content is more than 60%. Close the greenhouse film after feeding. Under the action of the heating agent, the feed temperature automatically increased by about 70 ℃ in 1-2 days, and then fell back after 2 days. Keep it for about 50 ℃ for 4 days, then open the shed for ventilation, drop the material temperature to normal temperature, and then turn the material and sow. According to their own experience, bed planting, border planting, bag planting, scientific cultivation and management.
