摘　　要：针对设施甜瓜-豇豆种植模式中甜瓜秧蔓处理和豇豆根腐病问题,开展了设施甜瓜秧蔓直接还田种植豇豆试验,分析其对下茬豇豆根系和制种产量的影响。结果表明,甜瓜秧蔓直接还田后种植豇豆,豇豆平均主根长、根干质量极显著高于甜瓜秧蔓未还田处理,分别提高63.43%、59.54%;甜瓜秧蔓未还田种植的豇豆根腐病病株率、病情指数分别为还田处理的3.53、8.58倍,差异极显著;甜瓜秧蔓还田处理后豇豆种子产量极显著高于甜瓜秧蔓未还田处理,提高58.64%;豇豆主根长、根干质量均与豇豆种子产量呈极显著正相关;豇豆根腐病病株率、病情指数均与豇豆种子产量呈极显著负相关。甜瓜秧蔓配施微生物菌剂直接还田,显著减轻了下茬豇豆根腐病的发生程度,促进了下茬豇豆根系的生长,提高了下茬豇豆的种子产量。In order to solve the problems of muskmelon vine treatment and cowpea root rot in the greenhouse muskmelon-cowpea planting model,the experiment of muskmelon vine returning directly to the field to plant cowpea was carried out,to analyze the effect on root system and seed production yield of next crop cowpea.The results showed that the average root length and root dry weight of cowpea were significantly higher than those of the control,which increased by 63.43%and 59.54%respectively.The percentage of diseased plants and disease index of cowpea root rot were 3.53 and 8.58 times higher than those of the control,respectively.The seed yield of cowpea was significantly increased by 58.64%after the treatment of muskmelon vine returning to field,and the main root length and root dry weight were positively correlated with the seed yield of Cowpea There was a significant negative correlation between the yield of cowpea seeds and the rate of diseased plants and disease index of cowpea root rot.The results showed that the application of microbial inoculants to muskmelon seedlings could significantly reduce the incidence of root rot,promote the root growth and increase the seed yield of next-cropping cowpea.
