常温栽培双孢菇,每年投一批料,从制种至结束出菇清棚的一个完整的生产周期,基本是一年或更长时间。虽然冬季不出菇、不管理,但是,基料依然占棚,等待春天气温回升后再度出菇,直至完成生产周期。在土地资源日益增值、劳动力价格只升不降、双孢菇产品涨价幅度过缓的社会条件下,过长的生产周期则意味着生产效益无奈的降低,甚至,相当数量的生产处于保本边缘,有的生产者在不计算生产管理成本的条件下没有利润,因此,双孢菇生产逐渐萎缩。在食用菌研发中,我们对“双孢菇 Agaricus bisporus cultivation at room temperature, cast a batch of material each year, from the seed to fruiting shed shed a complete production cycle, basically a year or longer. Although the winter does not fruiting, not managed, however, the base material still occupy the shed, waiting for the spring temperature rise again after fruiting, until the completion of the production cycle. Under the social conditions of increasing land resources, rising labor prices, rising prices of Agaricus bisporus products too slowly, too long a production cycle means the helpless reduction of production efficiency. Even a considerable amount of production is at the edge of capital preservation, Of producers did not make any profit without accounting for the costs of production management. As a result, Agaricus bisporus production was gradually shrinking. In the development of mushrooms, we are ”Agaricus bisporus
