【摘要】 为了解番木瓜连作及番木瓜分别与芥菜、甜玉米轮作模式下，番木瓜环斑花叶病的发病率及作物产量和经济效益情况，在广西横州市横州镇大和村开展调查。调查结果显示：番木瓜连作模式下，番木瓜环斑花叶病的发病率为70.7%，病情分级为5级，年平均收益为3837.5元/667 m~2；番木瓜—甜玉米轮作栽培模式下，番木瓜环斑花叶病的发病率为17.7%，病情分级为1级，年平均收益为4582.5元/667 m~2；番木瓜—芥菜轮作模式下，番木瓜环斑花叶病发病率为14.6%，比连作模式发病率减少56.1%，病情分级为1级，年平均收益为8625元/667 m~2，比连作模式增收124.8%，比番木瓜—甜玉米轮作模式增收88.2%。同时总结番木瓜—芥菜轮作模式的栽培技术要点，为进一步推广提供参考依据。更多还原

【Abstract】 In order to understand the Papaya ringspot virus(PRSV) disease occurrence rate,yield and economic benefits under the continuous cropping of papaya and the papaya-mustard or papaya-sweet corn rotation, the investigation was carried out at Dahe Village, Hengzhou Town, Hengzhou City, Guangxi. The results showed that: under the continuous cropping mode of papaya, the PRSV incidence of papaya was 70.7%, the disease grade was 5 and the annual average income was 3837.5 yuan/667m2; under the papaya-sweet corn rotation, the PRSV incidence was 17.7 %, the disease grade was 1 and the annual average income was 4582.5 yuan/667m2; under papaya-mustard rotation, the PRSV incidence was 14.6%, which was 56.1% lower than that in continuous cropping,and the disease grade was 1, and the annual average income was 8625 yuan/667m2, which was 124.8% higher than that in continuous cropping and 88.2 % higher than that in papaya-sweet corn rotation. At the same time, the key points of cultivation techniques of papaya-mustard rotation mode is summarized to provide reference for further promotion.更多还原
