摘要:
由疫霉属真菌引起的芋头疫病是限制芋头产量的关键因素之一。以泰兴香荷芋为材料,设置不同地膜颜色及厚度10个处理,研究不同地膜覆盖处理下芋头疫病发生规律及其产量表现。研究结果表明,芋头疫病病情指数在不同处理间达到显著差异(P<0.05),D4、D7、D9这3个处理疫病病情指数均超过40,均显著高于其他各处理,表现为感病,D1、D2、D8的病情指数分别为26.21、26.35、26.50,表现为抗性;各处理间在倒一叶、倒二叶上疫病病级无显著差异,而在倒3叶上则有显著差异,叶位间疫病严重程度为:倒三叶>倒二叶>倒一叶;不同处理间芋头产量差异性较大,变幅为8 441(D10)~15 758 kg/hm2(D3);芋头病情指数与产量间的相关系数为-0.723,两者相关性达到极显著(P<0.01)。
