Cultivation Techniques of High Temperature Mushroom Xiagu 93

Summer mushroom 93 is a high temperature mushroom variety selected by Zhejiang Academy of Agricultural Sciences. The cultivation techniques are as follows:

1. Cultivation season and facilities

The cultivation season is from late March to October in the south, from 5mi to September in the Yangtze River valley and from 6mi to August in the north. The disinfection of mushroom house can make use of conventional mushroom cultivation equipment such as existing mushroom house or plastic greenhouse in summer leisure period and plastic greenhouse cultivation. Generally, after the end of spring mushrooms, the waste is removed immediately, the mushroom house and bed frame are cleaned and disinfected, and sealed fumigation with dichlorvos and formaldehyde before cultivation.

two。 Rice and wheat straw are the main raw materials for composting and fermentation of culture materials. It is generally divided into two stages: outdoor composting fermentation and indoor post-fermentation. The fermentation time of outdoor composting is about 15 days, and the culture material is usually turned over 4 times in the process of composting. The quality requirements of outdoor composting fermentation of culture materials are as follows: the water content is about 65%; the PH value is about 7.5; the material is brown; there is stable fat flavor, but slightly ammonia flavor. After the outdoor composting fermentation of the culture material, the indoor post-fermentation must be carried out. Indoor post-fermentation requires room temperature and material temperature to reach 60 degrees Celsius, keep 6muri for 8 hours, and then naturally reduce the room temperature to 50Mel 54 degrees Celsius for 7 days. Pay attention to proper indoor ventilation. After fermentation, the culture material is dark brown; it is elastic and does not stick to hands; the whole material layer is covered with white actinomycetes; the clinker has no ammonia flavor and has fermentation flavor; the water content is 60% Mel 62%, and the PH value is 7.2 Mel 7.5.

3. Management of sowing and inoculation period after secondary fermentation, the culture material should be turned while it is hot, and the seed can be sown when the material temperature drops to the natural temperature. Sow 1.5 bottles of wheat seeds or 2 bottles of cottonseed hulls per square meter. The sowing method usually adopts surface sowing and mixed sowing, and then flattens the material surface after sprinkling the bacteria to make the material layer loose and tight.

The management of bacteriological period is mainly controlled by mild ventilation. The mycelial colonization period was within 5 days after sowing. During this period, it is necessary to maintain the appropriate temperature, humidity and stable microclimate environment in the mushroom room (shed), so that the hyphae can be quickly planted in the culture material. During the inoculation period, the temperature in the mushroom should be controlled as much as possible between 26 and 30 degrees Celsius, especially during the planting period; the hyphae can grow with temperatures of 38 degrees Celsius and 40 degrees Celsius in a short time. In case of high temperature, the amount of ventilation should be increased, the temperature in the mushroom room should be reduced to grow under suitable conditions, and the hyphae should be full of material layer for about 20 days. After the mycelium grows full of material layer, it can be covered with soil.

4. There are three kinds of soil covering materials commonly used: chaff fine soil, coarse and fine soil and rice husk river soil. The covering material is disinfected according to the routine, and the thickness of the covering soil is required to be uniform. The thickness of the covering soil is usually 3.5cm and the water content is sufficient. After the soil surface water stains dry, you should close the doors and windows to promote the mycelium to climb the soil. Under suitable conditions, the hyphae can climb on the surface of the overlying soil after 5 murmurs for 7 days.

5. The mushroom production period is in the high temperature season. The temperature in the mushroom room is 30 degrees Celsius and the relative humidity is 85% and 90%. It is most suitable for the growth and development of mushroom fruiting body. Although the growing fruiting body can reach a high temperature of 40 degrees Celsius over a certain period of time, in order to improve the quality of the fruiting body, the temperature in the mushroom room should be reduced as far as possible to reduce the occurrence of diseases and insect pests.

6. Harvest high-temperature mushrooms during the whole growing period can harvest 5 Murray 6 tide mushrooms, generally each tide interval of about 7 days. Soil and water should be replenished after each tide mushroom is harvested. Due to the high temperature and the fast growth of the fruiting body, it should be harvested in time to avoid opening the umbrella. At the same time, in the harvest should be light picking, less turning, timely @ # @ 136 fresh mushrooms to ensure the quality of goods.
