摘　　要：利用白色防虫网(白网覆盖)和120 g/m2编织膜(编织膜覆盖)为覆盖材料,以露地栽培为对照,研究不同覆盖材料对豇豆生育期、株高、茎粗度、叶片叶绿素含量指数、产量和病虫害等的影响,以期为豇豆设施栽培及其覆盖材料的选择提供理论依据。结果表明:覆盖栽培比露地栽培能有效降低蓟马虫口数和轮纹病病情指数,其中白色防虫网覆盖延迟了豇豆的始花期和始收期、但提高了豇豆产量,编织膜覆盖促使豇豆始花节位升高、降低了豇豆产量。综合考虑,白色防虫网是适合三亚豇豆栽培的覆盖材料。In order to provide theoretical evidence for protected cultivation and covering materials selection,through the comparison of different covering materials（white fly net,weaving film） and open field on cowpea growth,leaf chlorophyll content index（CCI）,yield,diseases and pests.The results showed that protected cultivation could decrease thrips population and ring rot disease index effectively.The white fly net delayed the first flowering dates and first harvesting dates,but increased the yield of cowpea.The weaving film increased the first flower node and decreased the yield of cowpea.Conclusions demonstrated that the white fly net was suit for cowpea cultivation in Sanya.
