不同密度遮阳网覆盖对张良姜生长发育及产量的影响

为了确定平顶山地区张良姜合理的遮阳网密度，通过遮阳试验（0%遮阳、50%遮阳、70%遮阳）研究了不同密度遮阳网对张良姜在植物学性状、子姜数量、重量和主要物质含量的差异。结果表明，遮阳网处理均可提高张良姜的植物学性状、生姜仔姜性状指标和单株重，张良姜姜块的粗纤维在遮阳条件下较高，锌、镁0%遮阳下含量较高，50%遮阳处理钙含量高。综合各项指标50%遮阳网处理表现较优，可在平顶山地区推广，为指导生产提供良好的理论依据。

Effects of Different Densities of Shade Nets on Growth and Yield of Zhangliang Ginger

In order to determine the reasonable shade net density for Zhangliang ginger in the Pingdingshan area, through the shading test (0% shading, 50% shading, 70% shading), the difference in the botanical properties, quantity, weight and main substance content of Zhangliang ginger was studied under shade nets of different densities. The results showed that the treatment of shade nets could improve the botanical characters, young ginger characters and plant weight of Zhangliang ginger, the crude fiber of Zhangliang ginger was higher under shading condition, the content of Zn and Mg was higher under 0% shading, and the content of Ca was higher under 50% shading.Comprehensive performance of 50% shading nets of various indicators is relatively good,which can be promoted in Pingdingshan area,and can provid a good theoretical basis for guiding production. ;
