摘　　要：从6个蓖麻品种中选取4个发芽率较高的品种,进行正交试验设计研究不同蓖麻品种在不同湿度下的生长状况。结果表明,晋蓖2号在高湿度(95%)与低湿度(65%)的条件下,均具有较好的高与地径生长。而汾蓖7号在低湿度(65%)的条件下,植株地径与高生长较好。在所试验的4个蓖麻品种中,低湿度条件有利于地径的生长。From six different cuhivars of Riciuns communis, four cuhivars with high germination rate were selected as experimental materials for studying their growth situation at different humidity by orthogonal experiment. The results showed： Jin grate 2 grew well at the plant height and base diameter under the highest humidity （95%） or the lowest humidity （65%） conditions, while Fen grate 7 grew well at its height and base diameter under the lowest humidity （65%） conditions. Of all the 4 tested varieties, the lowest humidity condition was good for their base diameter growth.
