What should be noted when growing Agaricus blazei? Netizens, please help explainIf the growing method for Agaricus blazei is not in place, it will affectthe fruiting of Agaricus blazei and cause abnormal mushroom emergence; Zhongdiwang has sorted out based on these two pointsthe key points of Agaricus blazei cultivation for netizens' reference.
1. Main factors that affectAgaricus blazeifruiting:
1. Mushroom emergence temperature is the most important factor affecting the emergence of Agaricus blazei:
The mycelium culture temperature range of Agaricus blazei is wide (10-37°C), and problems generally do not occur in production. The key is the fruiting body formation stage, which requires a temperature of 20-33°C, with the optimum being 22-25°C, and it takes about 2 weeks from primordium differentiation to mushroom bud formation. For normal mushroom emergence in each flush in production, there must be a continuous ambient temperature of 20-33°C for about 20 days. The appearance of excessively low or excessively high temperatures during this period can lead to failure of normal fruiting.
Due to temperature reasons, 4 situations are often encountered in the production process: First, there is no stable climatic condition throughout the mushroom emergence season, and the temperature fluctuates suddenly high and low. Second, when favorable temperature conditions for mushroom emergence appear, the mycelium has not reached physiological maturity, or the mycelium recovery time during flush transition is insufficient, missing the mushroom emergence time. Third, when favorable temperature for mushroom emergence appears, no mushroom emergence management measures are taken. Fourth, the cultivation facilities are imperfect, no temperature regulation measures are taken, or the facilities used easily cause large temperature fluctuations.
2、Agaricus blazeicompost formula and treatment:
Agaricus blazeiAn unscientific compost formula or improper treatment can cause failure of mycelium growth or abnormal mycelium growth and mushroom emergence. The most common situations in production are:
① The cultivation raw materials selected are relatively single, fresh, and mainly woody materials, or the cultivation formula has obvious defects.
② The compost for sterilized cultivation has not undergone composting and maturation treatment, or acidified materials (such as manure and straw, etc.) are added.
③ The composting and fermentation of the compost are not carried out as required, or the fermentation fails.
3. Cultivation technical measures:
Cultivation management, especially some key technical links, has not taken corresponding measures, leading to mushroom emergence obstacles or pathological changes, mainly including:
① During the fruiting body formation stage, water and ventilation are not properly managed, making it difficult for fruiting bodies to form.
② The field plot for cultivation has not been treated for pests and diseases before use, and pest control measures during the cultivation stage are ineffective.
③ Due to rainwater erosion, the compost layer is soaked in water for a long time.
2. Methods to ensureAgaricus blazei normalmushroom emergence:
1. Reasonably arrange the production season:
Reasonably arranging the production season is the key to successful Agaricus blazei cultivation. Taking advantage of the wide mycelium growth temperature range of Agaricus blazei, appropriately arrange production earlier. Generally, according to local meteorological data, inoculation or sowing should be carried out 3 months in advance in the first ten-day period when the average temperature reaches 20-25°C, so that the physiologically fully mature mycelium waits for the suitable mushroom emergence period, and not the opposite.
Raw material cultivation generally does not arrange autumn mushroom emergence. For sterilized cultivation, "cross-season cultivation" should be considered, that is, inoculation in spring and mushroom emergence in autumn, or inoculation in autumn and mushroom emergence in the following spring.
2. Do a good job in the composting and fermentation of the compost:
Regardless of which cultivation method is adopted, the compost should be fermented. Among them, raw material cultivation should fully follow the fermentation process, and compost that is not thoroughly fermented or has failed fermentation should not be used. Sterilized cultivation can undergo "semi-fermentation", with a fermentation time of no less than 5 days (no less than 8 days for completely new materials), and turning the pile no less than 1 time during the process (no less than 2 times for completely new materials). The fermented compost should not have a sour or foul odor.
3. Take corresponding technical management measures according to the progression of the season and climate changes. The links that need attention in management include: ① When primordia appear, spray heavily and strengthen ventilation. ② During overwintering and oversummering, appropriately control the moisture of the compost layer. ③ Pay attention to pest and disease control during the mycelium growth period.
