为明确羊肚菌设施栽培中的最佳光照强度，为羊肚菌栽培提供技术支持。以陇南市主推品种六妹羊肚菌为试验材料，在塑料大棚上覆盖6针、8针、9针遮阳网，并在内部种植羊肚菌，研究不同光照强度对六妹羊肚菌全生育期菌丝生长、生物特性和产量的影响。结果表明，光照强度对羊肚菌栽培有较大影响，覆盖8针遮阳网下栽培的羊肚菌产量最高，菌丝生长最快，生物特性良好，故塑料大棚栽培羊肚菌光照强度应控制在 800～1 000 lx为宜。

In order to clarify the optimal light intensity in protected cultivation of Morchella esculenta, the main variety Morchella sextelata was planted in the plastic greenhouse of Longnan city covered with 6-pin, 8-pin, 9-pin shading nets, respectively, and effects of different light intensities on mycelium growth, biological characteristics and yields of M. sextelataat the growth period were studied. The results showed that yield of M. sextelata was the highest cultivated in the plastic greenhouse covered using 8-pin shading nets because of the fastest growth speed of its mycelium and good biological characteristics. Therefore, the suitable light intensity of M. sextelata cultivation in a plastic greenhouse should be from 800 to 1 000 lx.
