当前,世界各国设施蔬菜生产正在向节能方向发展.最近,由熊岳农业专科学校主持的利用聚脂膜反光幕改善温室光照效应的研究,已取得可喜的成果.这项新技术的推广将为北方冬季、早春的温室蔬菜生产,在节能前提下,增加光照,提高气温和地温,从而提高秧苗质量,促进蔬菜早熟、增产创出一条新路.利用聚脂膜反光幕改善温室光照效应的技术,是利用反光原理,把射入温室后部的太阳光线,用反光幕反射到栽培畦或苗床床面上,通过增加光照度提高温室的气温和地温,促进
At present, the vegetable production in facilities and facilities in various countries in the world is developing towards energy conservation.Recently, the research on the effect of improving the light effect of greenhouse using the polyester film reflective screen presided over by Xiong Yue Agricultural College has achieved gratifying results.The promotion of this new technology will be Under the precondition of energy saving, under the precondition of energy saving, the northern part will increase the light, raise the temperature and the ground temperature so as to improve the quality of the seedling and promote the precociousness of the vegetables and increase the yield, thus creating a new road. The technology of using the polyester film reflective screen to improve the greenhouse illumination effect , Is the use of reflective principle, the solar greenhouse into the back of the sun’s rays, with a reflective screen reflected to the cultivation of seedlings or seedbed bed surface, by increasing the light intensity to raise the greenhouse temperature and ground temperature, and promote
