摘　　要：为研究留茬高度对饲用辣木生长及产量的影响,对刈割留茬高度在40、60、80 cm的辣木进行生物量、回枯和抽发试验观测。结果表明:留茬高度60 cm的辣木饲料源产量要高于留茬高度40 cm和80 cm的,留茬高度80 cm刈割得到的辣木饲料源叶占总生物量的比重略高于其它处理,茎干占比略低于其它处理;留茬高度越高,发生回枯病的概率越小,回枯高度大部分集中在3 cm以内;留茬高度80 cm的抽发相对优于其它处理。Experiment of Moringa oleifera in stubble height of 40cm,60cm and 80cm,respectively was conducted to study the biomass,die back and sprout.The results showed that the yield for feed in stubble height of 60 cm was significantly higher than that of in 40 cm and 80 cm.The feed source of Moringa obtained in stubble height of 80 cm has a slightly higher proportion of leaves in total biomass and a slightly lower proportion of stems compared with other treatments.The higher the stubble height leaves,the slighter the incidence of blight would be.The height of regression is mostly concentrated within 3cm.It`s superior to leave the stubble in height of 80 cm for sprouting.
