One, dead mushroom reasons:
Sustained high temperature, poor ventilation, lack of nutrients, improper use of water, aging of hyphae, discomfort in acidity and alkalinity, excessive density of mushrooms and excessive parts, damage caused by diseases and insect pests, abuse of pesticides, etc. can lead to death of mushrooms.
Second, prevention and control measures:
1. Casting training materials. The growth and development of Agaricus bisporus is the same as that of any organism, and it needs to have a sufficient nutritional basis. It is necessary for mushroom cultivation to achieve high yields and to avoid the occurrence of mushroom bud death due to malnutrition. In the preparation of culture materials, it is required to supply 30 to 35 kg/sq. meter. , And conscientiously do a good job of composting materials and fermentation work, which is conducive to overcome the late mushrooms due to lack of nutrition and mushroom, so as to obtain high yield.
2. Use high quality strains. Select mycelium that grows strong and powerful. Culture medium nutrients should be sufficient, the training room clean, fresh air. The strain culture process should always check the temperature change, so that the mycelium grows at a suitable temperature, and the contaminated strains are eliminated in time.
3. Timely cultivation. General preparations, compounding in August, and sowing in September.
4. Scientific water. Moisture management should be due to the weather, the amount of mushrooms, according to time, sunny and more spray, less rainy days spray, more than spray spray mushrooms, mushrooms less spray.
5. Ventilation. The normal growth and development of mushrooms must absorb oxygen and emit carbon dioxide. High concentration of carbon dioxide is harmful to the development of fruit bodies. The long-term ventilation of the mushroom sheds is poor, and the concentration of carbon dioxide is too large and the oxygen is insufficient. This has an adverse effect on the growth and development of the mushrooms. Therefore, ventilation and ventilation must be observed during cultivation.
