The species must pay attention to the fermentation of Agaricus bisporus

The quality of the fermentation material of the culture material directly affects the production of the Agaricus bisporus. In the fermentation of Agaricus bisporus culture materials, many mushroom farmers have reduced the yield and quality due to their contempt for the fermentation of culture materials. When cultivated Agaricus bisporus, the following points must be mastered in the cultivation of fermentation materials:

The fermentation time of better fermentation time is in early August, because at this time, the fermentation culture material can use favorable conditions of high temperature in the fall, strive for a longer period of fruiting, and achieve better results. The favorable conditions from high to low, strive for a longer fruiting period, and achieve better results.

Selection of culture materials All culture materials require fresh and must not be mildewed.

Fermentation First of all, the pre-wetting of the culture material should be sufficient to avoid the phenomenon of insufficient water absorption of the culture material. Secondly, to build a heap to be scientific, it should adopt a north-south trend, with a stockpile width of 1.8-2 meters and a height of 1.5-1.8 meters. The lower floor should use bricks to build ventilation ducts. According to the requirements of the construction of the reactor, one layer of material is stacked on one pile of feces, and the moisture content of the culture material is kept at about 65%. Third, pay attention to turning the heap to be reasonable, such as taking a one-time fermentation, to turn 4 times, starting from the construction of the heap to calculate the number of days, the first turn on the seventh day, and then the sixth day, the fifth day, the fourth Days, the end of the fermentation immediately split into the house; if you take the second fermentation, to turn three times, respectively, on the fifth, fourth and third days. In the turning of the dumping, the contents of the inside and outside layers should be uniform to prevent the presence of raw material, and the moisture content of the culture material should always be maintained at about 65%. Fourth, the cultivation of materials should be prevented from rain, and when it rains, it should be covered with a film, and the rain should be removed to prevent groping.

It is advisable to properly control the maturity of the cultivation medium to cultivate the culture material of the Agaricus bisporus. The semi-mature culture material has the following four characteristics: First, the color of the feces changes from golden yellow or yellowish green to brown, but it is not black, and there is no smell of odor, sour smell or spoilage. The second is that the grass stems are soft, and there is a tensile strength and elasticity when hand-pulling, instead of being lightly pulled, that is, even if it is not mature, it cannot be seen as grass stems. Holding the culture material, it can be held in groups and loosen after loosening it. The third is that on the fifth day after the last tumbling, the temperature of the culture material is still above 50°C, but it must not exceed 60°C. The fourth is to reduce the volume of cultivating stockpiles by 40% from the original, 30% by weight, water content around 60%, and no water droplets appear between the fingers during hand-pinch.
