不同光强对非洲菊鲜切花产量和质量的影响

Effect of different light intensity onthe yield and quality of Gerbera jamesonii cut flowers

以海宁地区非洲菊主要栽培品种‘北极星'为材料,采用遮荫的方法研究了不同光强对非洲菊鲜切花产量和质量的影响。结果表明:为提高非洲菊鲜切花的产量和质量,在夏、秋季节海宁地区非洲菊的设施栽培过程中应该采用遮阳网进行遮荫,其中夏季日光直射的天气应按透光率为设施内自然光强的60%,秋季按透光率为设施内自然光强的80%最好。冬、春季节海宁地区非洲菊的设施栽培过程中可不遮荫,如在阳光较强的天气下进行遮荫,透光率应大于设施内自然光强的80%为宜。

Taking Gerbera jamesonii main cultivar ＇North Star＇ in Haining as materials,the effect of different light intensity on the yield and quality of Gerbera jamesonii cut flowers were studied by shading method.The result showed that in order to improve the yield and quality of cut flowers,Gerbera jamesonii should be shaded by sunshade nets in summer and autumn in Haining in the process of protected cultivation.The highest yield and quality of cut flowers achieved under 60%natural light intensity in summer direct sunlight weather and under80%natural light intensity in autumn.Gerbera jamesonii should be under full natural light intensity or higher than 80%strong sunlight intensity in winter and spring in Haining area.
