摘　　要：植物多样性对魔芋(Amorphophallus konjac)软腐病有较好的控制效果。此试验通过对农田草本植物采用不同的管理方式,设5个杂草处理。处理A:草高于魔芋后清除1次杂草;处理B:7、8月各清除1次杂草;处理C:将高于魔芋的杂草在低于魔芋叶片处剪断;处理D:杂草自然生长;CK:没有杂草,即随时除净杂草。研究农田草本植物对魔芋软腐病的控制效果及对产量的影响。试验结果表明:处理B的控病、增产效果最好。处理A、B、C防控魔芋软腐病的效果与处理D相比,在1%水平上差异显著。处理A、B的产量与处理D相比,在1%水平上差异显著。处理A、B的产量与CK相比,在5%水平上差异显著。CK的产量与处理D相比,在5%水平上差异显著。Plant diversity had good control effects against Konjac soft rot. In this experiment,five weed treatments were set. Treatment A： remove weeds once when the weed is higher than that of konjak. Treatment B ： remove weeds once in July and August. Treatment C： cut the weeds which are lower than the leaves of konjak. Treatment D： let weeds grow naturally. CK： no weeds, which means remove weeds anytime. The control effects against Konjac soft rot and yield were studied by different management methods of herbs in cropland. The results showed that it had good effects in the soft rot control and yield for the treatment B. It had significant differences at 1% for controlling soft rot in the A,B,C treatments compared with D. Yields had a significant difference at 1% in A,B compared with D,a significant difference at 5% in A,B compared with CK, and a significant difference at 5% in CK compared with D.
