| 摘 要： | 以小叶白子菜（富贵菜）为试验材料，采用白色防虫网、黑色防虫网、遮阳网覆盖材料，对白子菜的产量、品质及环境因子进行比较研究。结果表明：遮阳网与白色防虫网、黑色防虫网和露地处理相比，显著提高了产量，增加了叶片叶绿素含量，降低了设施内温度和光照强度，从而减少了硝酸盐含量，改善了白子菜品质，促进了白子菜植株生长。综合分析得出，遮阳网可在热带夏季白子菜设施栽培中推广应用。

| Abstract: | Using white insect-proof net,black insect-proof net and sun-shading net,we compared and studied the yield,quality,environmental factors of Gynura divaricata(L.)DC.The results showed that the quality and chlorophyll content were improved obviously,while the temperature and light intensity of greenhouse were reduced,the nitrate content was also decreased,the quality and growth of Gynura divaricata(L.)DC.were improved under sun-shading net cultivation.The comprehensive analysis shows that sun-shading net can be extended and applied in protected cultivation of Gynura divaricata(L.)DC.in summer at tropical areas. |
