| 【目的】探索基质料水比对蛹虫草生长发育相关指标的影响，为蛹虫草的高产优质栽培提供依据。【方法】以蛹虫草菌株CM 16为研究对象，小麦为主要栽培基质，采用规格为300 mm×200 mm×110 mm的蛹虫草栽培专用盘，设置基质料(g)水(mL)比分别为1∶1.3，1∶1.4，1∶1.5，1∶1.6和1∶1.7，研究基质料水比对蛹虫草的子座鲜质量、生产周期、子座密度、子座长度、子座生物学效率及基质利用率的影响。【结果】随着基质料水比的增加，蛹虫草子座鲜质量、子座密度、子座生物学效率和基质利用率均呈先增加后降低的趋势，生产周期呈先降低后增加的趋势，子座长度变化幅度较小。当基质料水比为1:1.6时，上述6个指标均达到最大值，其中，子座鲜质量为305.9 g/盒，生产周期为56 d，子座密度为8.9根/cm2，子座长度为9.7 cm/个，子座生物学效率为102%，基质利用率为51.5%。【结论】基质料水比是影响蛹虫草生长发育及子座产量的重要因素，当以小麦为主要原料栽培蛹虫草时，最佳基质料水比为1∶1.6。 |

| Abstract: |
| 【Objective】This study was to research the effects of medium substrate-to-water ratio on correlated growth and development indexes of Cordyceps militaris.【Method】Cordyceps militaris strain CM-16 was used as test material and wheat was used as the main cultivation medium.300 mm×200 mm×110 mm plates were used to cultivate Cordyceps militaris,and 5 substrate(g)-to-water(mL) ratios,1∶1.3,1∶1.4,1∶1.5,1∶1.6 and 1∶1.7 were tested to obtain the effect of medium substrate-to-water ratio on stroma fresh weight,production cycle,stroma density,stroma length,srtoma biology efficiency and medium utilization rate of Cordyceps militaris.【Result】With the increase of medium substrate-to-water ratio,stroma yield,stroma density,stroma biology efficiency,and medium utilization rate increased initially followed by decrease while production cycle decreased before increasing.Stroma length did not change dramatically.When the medium substrate-to-water ratio was 1∶1.6,six indexes reached maximum (the stroma yield 305.9 g/box,the production cycle 56 days,the stroma density 8.9 cm-2,the stroma length 9.7 cm,stroma biology efficiency 102% and medium utilization rate 51.5%).【Conclusion】 The medium substrate-to-water ratio played an important role in affecting growth,development and stroma yield of Cordyceps militaris.The obtained best substrate-to-water ratio for wheat was 1∶1.6. |
