Lighting Design of Chinese Traditional Buildings and Application of New Type of Little Power LED

This paper is a part of the research on the lighting techniques of the traditional Chinese buildings in Summer Palace,Beijing,which is a sub-project of the Municipal Research Project on the Correlative Techniques for Beijing's Sustainable Development(Y0604017040391).The work,which the authors took part in,on the most representative Chinese traditional buildings in Summer Palace,is taken as a case study on lighting design and lab simulated experiments and checked by practical result,illustrating a working frame for other similar lighting design works.     

Nutritional response of seedling tomato plants under different lighting treatments

In order to describe the effect of complementary artificial light supply on the nutrient status of tomato seedlings, fluorescent lamps were compared to each other. Nitrogen (N), phosphorus (P), and potassium (K) concentrations were measured (mg g^?1 dry matter). Blue, red and far-red relationships were established. The N, P and K higher concentration and uptake have been found under high efficiency fluorescent lamps. Phosphorus uptake increasing was observed at high levels of irradiation. Potassium concentration is significantly higher under compact fluorescent lamps. The relationship between ratios and N, P and K extractions were used as indicators of limitation for plant. The ratio N/P and N/K present a low relation with N extraction. The ratio N/P presents a significant correlation with P extraction, also the ratios N/K and P/K with K extraction. Significant differences in constant of lineal equation have been found in P/K ratio and K extraction.     

佳多频振式杀虫灯在有机茶园害虫防治中的应用效果

【研究目的】试验研究频振式杀虫灯在有机茶园中的应用效果,为有机茶园防治害虫提供方法和指导;【方法】本试验共两个处理：有灯区和无灯区。在每年的6、7、8、9、10月份对杀虫灯诱杀的成虫的种类和数量进行统计,以及田间虫口密度为害情况调查。【结果】有灯区和无灯区中毒蛾、尺蠖、叶甲的数量差异达到了极显著水平;【结论】频振式杀虫灯对茶园害虫的防治效果明显,特别是对毒蛾、尺蠖和叶甲类的诱杀作用较突出,对它们的防效有灯区与无灯区间差异达到了极显著水平,但是对叶蝉的防治还是有一定的局限。频振式杀虫灯可以作为有机茶园防治虫害的一种手段,与其它防治方法协调使用,综合防治茶园害虫。

光纤发光诱虫灯对茶树害虫的诱捕效果研究

为了对茶树害虫进行科学的测报和诱捕,设计了一种光纤发光诱虫灯,开展了光纤发光诱虫灯在不同发光颜色、不同亮灭规律的情况下与频振式杀虫灯对茶树害虫的诱集对比试验。试验结果表明:光纤发光诱虫灯在亮2min-灭1min的亮灭规律下诱虫效果和能耗均好于频振式杀虫灯;在绿、黄、蓝、白4种发光颜色中,黄色光诱虫效果最好。同时,进一步证实了频振式杀虫灯具有更好的杀虫稳定性;但对茶树害虫天敌也有很强的杀伤力,应科学制定开灯方案。综合诱虫效果、能耗和使用寿命,光纤诱虫灯具有良好的应用前景。
