Abstract

The emission of microwave sulfur lamp is mainly composed of visible light. The sulfur lamp, producing little infrared radiation, has high efficiency, long duration of illumination and less energy consumption. In order to probe the agricultural application of the lamp, experiments were carried out with wheat (cv. Yangmai 158) to emphatically study illuminating effects of xenon or sulfur lamp on tillering, jointing and net photosynthetic rate during tillering and jointing periods. Results indicated that there is almost no difference in net photosynthetic rate of wheat leaves growing under different lamps. Xenon lamp significantly advanced the time of jointing, decreased number of tillers, number of total leaves per plant and leaf size, as well as inhibited root growth. In contrast with xenon lamp, sulfur lamp evidently delays the time of heading and grain maturation, increased number of heads per plant, head length, total number of grains per plant, head weight and total grain weight per plant, accordingly
