摘要
兰州地区的光照条件优越,昼夜温差大,十分适合一些经济作物生长,而冬春季时常伴有沙尘,雨雪等恶劣天气,导致光照质量下降,产量不佳.本研究以切花玫瑰为例,通过在冬春季的兰州地区玻璃温室内设置LED补光,以不补光为对照,研究LED补光对温室内切花玫瑰产量和采收周期的影响.研究结果表明,补光后,两个品种的切花玫瑰产量均有不同程度的提高,其中"蜜桃雪山"的增产率最高,达到了54％,采收周期也缩短最多,达到了4天.该研究成果对提高兰州地区温室的冬春季切花玫瑰产量提供了建议,也为西北其他地区温室冬春季作物补光应用提供了参考依据.
Abstract
Lanzhou has excellent light conditions and a large temperature difference between day and night,which is very suitable for the growth of some cash crops,but the winter and spring are often accompanied by sand,dust,rain and snow and other bad weather,which leads to a decline in the quality of light and poor yields.In this study,we took cut flower roses as an example,and investigated the effect of LED supplemental light on the yield and harvesting cycle of cut flower roses in a glass greenhouse in Lanzhou area in winter and spring by setting LED supplemental light,with no supplemental light as a control.The results showed that the yields of the two varieties of cut roses were increased to different degrees after supplemental lighting,with 'Peach Snow Mountain'having the highest yield increase of 54％,and the harvesting cycle was shortened by 4 days.The research results provide suggestions for improving the yield of winter and spring cut roses in greenhouses in Lanzhou,and also provide a reference for the application of supplemental light to greenhouses in other regions of Northwest China in winter and spring crops.
