New methods for preventing and controlling dead mushrooms in button mushrooms
(Agricultural Wealth Network) The production of button mushrooms has developed rapidly, forming a certain area and scale, but the yield is not very high, especially the problem of dead mushrooms, which has a great impact on yield and economic benefits. We have summarized the following new prevention and control methods for this situation, for everyone's reference.
I. Causes of dead mushrooms:
Sustained high temperatures, poor ventilation, insufficient nutrients, improper watering, mycelial aging, unsuitable pH, overly dense fruiting with too high positions, damage from pests and diseases, and abuse of pesticides can all lead to dead mushrooms in button mushrooms.
II. Prevention and control measures:
1. Apply sufficient compost. The growth and development of button mushrooms, like any living organism, requires a sufficient nutritional foundation. To achieve high yields in mushroom cultivation and avoid the death of mushroom buds due to malnutrition, when preparing the compost, the application rate should be 30-35 kg per sq m, and the composting and fermentation work should be done carefully. This helps overcome dead mushrooms caused by insufficient nutrients in the later fruiting stage, thereby achieving high yields.
2. Select high-quality spawn. Choose spawn with robust and vigorous mycelial growth. The spawn culture medium must have sufficient nutrients, and the culture room should be clean, sanitary, and well ventilated. During the spawn cultivation process, temperature changes should be checked frequently so that the mycelium grows at a suitable temperature, and contaminated spawn should be eliminated promptly.
3. Cultivate at the appropriate time. Generally, materials are prepared and composted in August, and spawning is done in September.
4. Water scientifically. Water management should be adapted to the weather and the amount of fruiting, and adjusted according to the time. Spray more on sunny days, less on cloudy and rainy days, spray frequently when there are many mushrooms, and spray cautiously when there are few.
5. Ventilate and exchange air. The normal growth and development of mushrooms must absorb oxygen and release carbon dioxide. High concentrations of carbon dioxide are harmful to the development of fruiting bodies. If the mushroom shed has poor ventilation for a long time, the carbon dioxide concentration will be too high and oxygen will be insufficient, bringing adverse effects on mushroom growth and development. Therefore, attention should be paid to ventilation and air exchange during cultivation.
