摘　　要：针对道地产区茯苓栽培时诱引植入部位和采收时间随意的现象,开展了不同的诱引部位与采收时间对茯苓菌核产量的影响试验,研究新鲜菌核诱引置于栽培窖内段木前端和尾端,以及菌核形成的不同时期新鲜菌核的产量,以期为湖北产区茯苓规范化种植提供科学依据。结果表明,诱引植入段木前端的菌核平均产量为1.277kg,植入段木尾端的平均产量为0.512kg,产量相差悬殊。茯苓菌核于10月和11月采收的平均产量分别为0.512kg、0.568kg,方差分析显示F<F_(0.05),无显著差异。结合该年度气候分析,茯苓栽培时,诱引植入段木尾端,受外界气候的影响较大,对产量的影响存在一定的不确定性,以前端植入诱引为宜;菌核变为深褐色,表皮裂纹渐趋弥合之后,茯苓即可陆续采收。In view of the phenomenon that fresh sclerotia implantation site and harvest time was very casual during P.cocos cultivation,discussed the effects of different inducing site and harvesting time on the Sclerotinia yield,In order to provide a theoretical basis for the standardized cultivation of P.cocos in Hubei Province.The results show that,the average yield was 1.277kg when inducing site at the wood front end,the average yield was 0.512kg when inducing site at the wood tail end,.There was a great difference in the yield between them.The average yields which collected in October and November were 0.512kg and 0.568kg respectively,variance analysis showed that F<F_(0.05),there was no significant difference.Combined with the climate analysis of that year,inducing site at the tail end was greatly affected by the external climate during the cultivation.There was some uncertainty on sclerotia yield.Therefore,it was appropriate to inducing site in the front end.When the sclerotia turned dark brown and the crack was gradually closing,P.cocos can be harvested successively.
