不同遮阴度对魔芋软腐病的影响

Effects of Different Shading Degrees on Konjac Soft Rot

通过调节魔芋(Amorphophallus konjac)/玉米(Zea mays L.)套作的种植密度来控制遮阴度,研究了不同遮阴度对魔芋软腐病发生的影响。结果表明,套作时玉米的种植密度在18 000～22 500株/hm2,魔芋的种植密度为37 500～45 000株/hm2时可显著降低魔芋软腐病的发生率。

The shading degree in field was modulated by adjusting the density of intercropped konjoc（Amorphophallus konjac） and maize（Zea mays）;and its effect on the incidence of konjac soft rot disease was studied.It was showed that the incidence of soft rot disease was significantly decreased when the density of corn was 18 000～22 500 ind./hm2 and of konjac was 37 500～45 000 ind./hm2.
