象草（Ｐｅｎｎｉｓｅｔｕｍｐｕｒｐｕｒｅｕｎ）经过三年的引种栽培，制菇试验，一般山地年均６０～１２０ｔ／ｈｍ２，可配料袋栽香菇１１６７万段，每万段菌棒替代木屑３１５０ｋｇ，折４３７５ｍ３，减少麦麸４５０ｋｇ，增收节支２０７０元。氨基酸总量和多糖含量均高于对照的１１１倍和１１４倍。开发利用象草代料制香菇，不仅高产优质，而且能获得较高的经济、生态和社会效益，是当前我国南方菇区营造食用菌后备资源的一项新途径。
Grass weeds (Pennisetumpurpureun) after three years of introduction of cultivation, mushroom test, the average annual mountain 60 ~ 120t / hm2, can be planted bags of mushrooms 116,600 segments, each paragraph of fungus rods instead of sawdust 3150kg, folding 4 375m3 , Reduce wheat bran 450kg, increase income and save 2070 yuan. The total amount of amino acids and polysaccharides were 111 times and 114 times higher than the control. The development and utilization of grass-like mushrooms, not only high yield and quality, but also access to a higher economic, ecological and social benefits, is currently mushroom zone in southern China to create a reserve mushroom resources a new way.
