利用EM菌、CM菌和酵素菌3种发酵菌堆制木薯皮基质,研究不同发酵菌堆制的木薯皮作为单一基质和混合基质[V(木薯皮):V(沙)=5∶1]对黄瓜幼苗生长及光合的影响.结果表明:与没有添加发酵菌堆制相比,木薯皮添加发酵菌堆制后,总孔隙度变化不大,持水孔隙度增加;根据形态指标判断,单一基质栽培黄瓜,EM发酵菌表现最优,混合基质栽培黄瓜,酵素菌表现最好;根据光合潜力来判断,单一基质栽培时,酵素菌表现最优,复合基质栽培时,CM菌表现最优;无论是从生长还是光合潜力来讲,添加发酵菌堆制基质,栽培黄瓜的效果都要优于不添加发酵菌.%Three microbial fermentation agents were inoculated into cassava bark to explore their effect on cucumber growth and photosynthetic capacity after mixed with or without sand with an aim to better use cassava bark, a tropical agricultural waste. Little change was seen in the total porosity, while an increase in waterholding porosity when three microbial fermentation agents were added. EM was the best in the single substrate while BYM was the best in the mixed substrate according to cucumber growth state. A rise in Pn and Ls, and a decrease in Ci and Tr were the observed in the mixed substrate compared with the single substrate. The photosynthetic capacity of cucumber was the highest when BYM was inlculatd into cassava bark in the single substrate cultivation and CM was addied to the mixed substrate.
