| 摘要: |
| 【目的】研究温度对大球盖菇生长发育的影响，为其栽培管理提供参考。【方法】在不同温度条件下，研究大球盖菇孢子萌发的适宜温度；采用正交多项式回归分析法构建数学模型，揭示温度对大球盖菇菌丝生长速率、出菇数量及产量的影响。【结果】经过冷刺激（5 ℃下冷藏30 d）后，大球盖菇孢子萌发的适宜温度为28 ℃；大球盖菇菌丝生长的最适温度为26.0 ℃；采用温室栽培，当菌床基质中心温度为18.7 ℃时，大球盖菇的产量最高、出菇数量较多；菌床基质中心温度在16～19.4 ℃时，大球盖菇子实体形态较好。【结论】冷刺激及高温是大球盖菇孢子萌发的重要条件，温度是影响大球盖菇生长发育、高产及优质的关键因素。 |

| Abstract: |
| 【Objective】This study investigated the effects of temperature on growth of Stropharia rugoso-annulata to provide reference for cultivation and management of S.rugoso-annulata.【Method】Different temperatures were tested to obtain the optimum temperature for S.rugoso-annulata spore germination.Orthogonal polynomial regression method was used to build model for investigating effects of temperature on hypha growth rate, fruit body amount and yield of S.rugoso-annulata.【Result】The optimum temperature for S.rugoso-annulata germination after cold stimulation (5 ℃,30 d) was 28 ℃ and the optimal temperature for hypha growth was 26.0 ℃.In greenhouse,when the center temperature of fungus bed matrix was 18.7 ℃,the fruiting body numbers and yield of S.rugoso-annulata reached the highest values.When the center temperature of fungus bed matrix was 16－19.4 ℃,the shape of fruiting body was the best.【Conclusion】High temperature and cold stimulation treatments were essential conditions for germination of S.rugoso-annulata spore.Temperature was the main factor influencing growth,high quality and yield of S.rugoso-annulata. |
