【摘要】 蛹虫草是一种珍贵的药食同源大型真菌,其市场需求日益增加。为加强蛹虫草的人工栽培,从料水比、菌种浓度、接种量和暗培养时间等4个因素进行正交试验,发现接种量(15、20、25mL/瓶)和茵种浓度(6、11、15个/mL)起着重要的作用,而料水比(1：1、1：1．2、1：1．5)和暗培养时间(2、3、4d)作用较小,并优化出高产培养条件．即料水比1：1．5、茵种浓度15个/mL．接种量25mL/瓶和暗培养时间为3d。在此优化条件下．每20g大米能生产出高达17．96g鲜子实体。更多还原

【Abstract】 Cordyceps militaris(L.:Fr.)Link is a valuable edible and medicinal fungus,and its market requirement is keeping growing.In order to increase the yield,some factors were studied to optimize the culture conditions.These factors included substrate-to-water ratios(1:1,1:1.2,1:1.5),mycelial pellets concentrations(6,11,15 pellets/mL),inoculation volumes(15,20,25mL/bottle)and dark cultivation time (2,3,4d).The results showed that the inoculation volume and the mycelial pellets concentration performed greatly;the substrate-to-water ratios and the dark cultivation time bad little effects.Substrate-to-water ratio at 1:1.5,15 pellets/mL of seeds,inoculation of 25mL/bottle and 3d dark cultivation composed the optimized condition.Up to 17.96g of fruitbody(wet weitht)per 20g of rice was produced under it.更多还原
