Abstract:
Taking Chinese chive and watermelons as experimental materials，watermelon-Chinese chive rotation (T1)，watermelon companion cropping with Chinese chive (T2)，and a combination of both (T3) were used to study control efficacy of watermelon-Chinese chive rotation and watermelon companion cropping with Chinese chive on Fusarium wilt and its effect on soil fungal community，in order to provide reference for the prevention and mechanism of watermelon Fusarium wilt in watermelon-Chinese chive rotation and watermelon companion cropping.The results showed that three treatments could effectively prevent the occurrence of Fusarium wilt，T1 and T3 delayed the onset of the Fusarium wilt，T3 had the best effective and not significantly different from T2，reaching 100.0%，93.8% and 93.0% at the beginning of fructification，fruit swelling stage and harvest period，respectively.In each treatment，the activities of soil urease，catalase，sucrase，and acid phosphatase were raised，the soil fungal community diversification was improved，effects of T3 was better.From beginning of fructification to fruit swelling stage，the soil urease，sucrase and acid phosphatase activities of each treatment was increased，the catalase activity was decreased，the soil bacterial community diversifications showed a downward trend.Soil fungal community specificity showed T3>T1>T2>CK.At the phylum and genus levels，T1 and T3 fungal community structure varied significantly compared with CK and T2.Soil fungal community specificity and structural differences were all correlated with the degree of pathogenesis.Three treatments changed the relative abundance of soil fungal flora，and especially reduced the relative abundance of toxigenic groups (Fusarium).The relative abundance of soil fungal flora varied in different fertility periods.Both watermelon-Chinese chive rotation and watermelon companion cropping with Chinese chive could change the activity of soil enzymes，the diversity，specificity，composition and structure of fungal communities，and effectively prevent and control the occurrence of watermelon Fusarium wilt.The effect of T3 was better.Considering the practicability，watermelon-Chinese chive rotation should be an effective measure to control watermelon Fusarium wilt in production.
