不同遮荫度和不同栽植密度对独角莲产量的影响

Effect of Different Shading and Cultivation Density on Yield of Typhonium giganteum

以独角莲为试材，研究了覆盖不同遮光度的遮阳网，以及不同栽培密度对独角莲产量的影响，以期为独角莲大面积栽培提供依据。结果表明：覆盖遮阳网可显著提高独角莲的产量并防止早霜，同时还提高了叶片中叶绿素的含量；3针遮阳网（遮光度80％）覆盖的独角莲块茎的产量最高，增产幅度48．72％。种植密度为20cm×15cm的独角莲（球茎重6．6～8．6g）667m^2产量最高，为744．444kg。

Taking Typhonium giganteum as material, in order to achieve a high yield, the best light condition and cultivatioll density for Typhoniwn giganteum through experiments with different shading and cultivation density were studied. The resuhs showed that shading nets could prevent early frost, significantly increased the yield of typhonium giganteum and enhance the percentage of chlorophyll in leaves. According to the experiments,80% shading resulted in highest yield of Typhonium giganteum tubers,with an increase of 48. 72% ;a density of 20 cm×15 cm led to the highest yield of Typhonium giganteum（corm weight 6. 6-8. 6 g） ,744. 444 kg/667m^2.
