针对甘肃省目前香菇品种繁多、栽培技术不精准等问题，以L808、申香215、238、0912和申香1513等5个不同特性的香菇品种为供试品种，设置不同的养菌温度、刺孔方式、出菇温度，筛选适应性强、耐温差、易管理、产量高、品质优的香菇优良品种，并提出不同生育阶段的精准化栽培管理技术。结果表明，香菇品种L808和238表现优良，菌棒培养阶段采用20~22 ℃的控温培养、刺孔2次，大棚自然出菇(16~28 ℃)的栽培方法表现最佳，生物学转化率、优质菇率相对较高。

In view of the issues of numerous varieties of Lentinula edodes and inaccurate cultivation techniques in Gansu Province, 5 L. edodes varieties with different characteristics such as L808, Shenxiang 215, Shenxiang 238, Shenxiang 0912 and Shenxiang 1513 were used as test varieties. By setting different cultivation temperatures, piercing methods and fruiting temperatures, the excellent varieties of L. edodes with strong adaptability, temperature tolerance, easy management, high yield and good quality were screened out, and the precise cultivation and management techniques at different growth stages were put forward. The results showed that L. edodes L808 and 238 performed well. The temperature control culture at 20 to 22 ℃ and piercing twice were used in the rod culture stage. The cultivation method of natural fruiting (16 to 28 ℃) in greenhouse showed the best performance, and the biological conversion rate and high-quality mushroom rate were relatively high.
