Thus the Agaricus bisporus supply is not available throughout the year. Even worse, the price of Agaricus bisporus is cheap in boom season, reduc- ing the economic benefits; but the product is unavailable off season. The whole-year production of Agaricus bisporus will help to solve the problem and increase the eco- nomic benefits of farmers. In this paper, the whole-year cultivation techniques of Agaricus bisporus were summarized. There are a total of 3 seasons of Agaricus bisporus (spring, summer, autumn-winter) throughout the year. And thus the whole- year supply of Agaricus bisporus is achieved, the utilization of mushroom house is improved and the income of farmers is increased.展开更多
