Two purple-leaf rice varieties (B151 and GY7) were selected as experimental material to discuss the growth variation of purple-leaf rice in different light conditions, so that we can make purple-leaf visual rice planting techniques and broaden application path. The light conditions of home and garden are simulated, and set three light treatments and two processing in time. We studied the effects of diverse light conditions on leaf color, leaf number, leaf area, flag leaf traits, tillering, effective panicle, plant length and stress resistance. The results show that the shortening of natural light time and the decreasing of light intensity leads to fewer tillering and leave number, lighter purple-leaf and effective panicle, and the length, width and angle of flag leaf increased. To sum up, purple-leaf visual rice plants still have extremely visual value, and can be planted in home and garden.
