| 摘要: |
| 【目的】探讨杏鲍菇栽培基质不同含水率对其生长发育的影响规律，为杏鲍菇的生产管理提供参考。【方法】以杏鲍菇PE-1菌株为供试材料，在栽培基质含水率为59.0%，60.5%，62.0%，63.5%，65.0%，66.5%和68.0%时,以该菌株生长周期、子实体形态及基质利用率为指标,研究不同含水率基质对杏鲍菇生长发育的影响。【结果】当栽培基质含水率为65.0%左右时，各指标均达最大值，其中，子实体鲜质量为286 g/袋，生产周期为48.5 d，子实体密度为0.528 g/mm3，子实体长度为191 mm，栽培基质利用率为35.68%。【结论】杏鲍菇栽培基质的最佳含水率为65.0%，此时杏鲍菇的生物学效率最高、密度最大、生产周期最短、经济效益最佳。 |

| Abstract: |
| 【Objective】The study was made to research the effect of water content of cultivation matrix on growth of Pleurotus eryngii.【Method】Pleurotus eryngii strain PE-1 is used as test material for the research,with production cycle,fruit body form and cultivation matrix utilization rate in 59.0%,60.5%,62.0%,63.5%,65.0%,66.5% and 68.0% on water content of cultivation matrix as the index to research effect of water content of compost on growth of Pleurotus eryngii.【Result】When water content of cultivation matrix is 65.0%,all indexes reach maximum,the fruit body fresh weight reaches 286 g/bag,the production cycle is 48.5 days,the fruit body density reaches 0.528 g/mm3,fruit body length 191 mm and cultivation matrix utilization rate 35.68%.【Conclusion】The optimal water content of cultivation matrix on Pleurotus eryngii is 65.0%,at the rate,it has the highest of biological efficiency,the largest of fruit body density, the shortest of production cycle and the best of economic benefit. |
