摘　　要：通过太阳光谱以及菊花、番茄作用光谱的测试分析 ,讨论了植物生长与太阳光谱的关系 ,表明太阳光谱中 2 80～ 380nm的紫外光 ,5 0 0～ 6 0 0nm的绿黄光及 72 0nm以上近红外光植物利用率较低 ,4 30～ 4 80nm的蓝紫光和 6 30～ 6 90nm的红光有利于增强光合作用。依据植物光合作用和太阳光谱特征 ,设计出CaS∶Cu+ ,Cl-蓝光膜 ,利用CaS∶Eu2 + ,Mn2 + ,Cl-,设计出绿光转红光的红光膜。讨论了红蓝复合双峰增益膜及紫外光转红光的稀土有机配合物的光谱特性。农用光能转换剂研制面临新的突破 。The solar spectrum and the function spectrum in chrysanthemum and tomato were determined in this paper. The research for a relation plant growth to solar spectrum showed that the efficiency of plant making use of ultraviolet light of 280-380 nm and yellow-green light of 500-600 nm and near IR spectra over 720 nm are lower, that the blue-purple light of 430-480 nm and red light of 630-690 nm are beneficial to enhancing photosynthesis and promoting plant growth. According to plant photosynthesis and solar spectrum characteristic, the author developed CaS:Cu+, Cl- blue light film, and red light film added with CaS:Eu2+, Mn2+, Cl- to convert green light into red light, and discussed the spectrum characteristic of red-blue double peak in agricultural film and rare earth organic complex which could convert ultraviolet light into red light. just now, the study on light conversion regents in farm films is going to face new breakthrough and the technology of anti-stocks displacement to study red film which can convert near infrared light are worth to attention.
