摘　　要：以泰国青骨柳叶空心菜为试验材料,采用白色防虫网、黑色防虫网、遮阳网进行覆盖处理,对空心菜的单株质量、内在品质及设施环境因子进行比较研究。结果表明,黑色防虫网较之白色防虫网、露地栽培处理,显著提高了空心菜的产量,增加了叶片叶绿素含量,减少了硝酸盐含量,调节了设施温度和光照强度,改变了空心菜品质,促进了空心菜植株生长。综合分析得出,黑色防虫网可在热带地区夏季的空心菜设施栽培中推广应用。The weight,quality and microclimate factors of Ipomoea aquatica Forsskal covered with white insect-proof net,black insect-proof net and sun-shading net were analyzed.The results showed that the quality and chlorophyll content were improved obviously,the nitrate content was decreased,the temperature and light intensity in greenhouse were adjusted,and the quality and growth of I.aquatica was improved best with black insect-proof cultivation.The comprehensive analysis showed that black insect-proof could be popularized and applied in facility cultivation of I.aquatica in tropical summer.
