峨眉山地区林下栽培灵芝技术研究

Study on the Technology of Cultivating Ganoderma lucidum under the Forest in Emei Mountain Area

在峨眉山地区从不同的灵芝种质资源、栽培基质配比、定植方式等方面研究了灵芝林下栽培技术。结果表明,采用朵型较大的灵芝种质资源ZL81林下栽培时,生长周期较短,为114 d,产量较高,为69.53 g/(kg·袋);使用配方为棉籽壳40%、杂木屑35%、玉米芯15%、麦麸8%、石膏1%、石灰1%的菌袋进行林下栽培时,产量最高,为71.3 g/(kg·袋),多糖含量为1.02%,三萜及甾醇含量为0.83%。采用菌棒横竖交叉为2层摆放的定植方式(第2种),产量为76.23 g/(kg·袋),优于将菌棒平铺的定植方式(第1种);2种定植方式栽培出的灵芝多糖含量相近,第1种定植方式三萜及甾醇含量优于第2种,为1.05%。

In the Emei Mountain area,the cultivation techniques of Ganoderma lucidum under the forest were studied from different Ganoderma lucidum germplasm resources,cultivation substrate ratio and planting methods.The results showed that when using the larger flower type of Ganoderma lucidum germplasm resource ZL81 under the forest,the growth cycle was shorter for 114 days,and the yield was higher at 69.53 g/(kg·bag).When using the formula with 40%cottonseed hull,35%wood chips,15%corncob,8%wheat bran,1%gypsum and 1%lime,the highest yield was 71.3 g/(kg·bag),the polysaccharide content was 1.02%,and the triterpene and sterol content was 0.83%;the method of planting rods crossed vertically and horizontally for two layers(the second method)could produce 76.23 g/(kg·bag),which was better than the method of planting rods flat(the first method).The polysaccharide content of Ganoderma lucidum cultivated by the two methods was similar,and the triterpenoids and sterols content of the first method was better than that of the second method,which was 1.05%.
