Abstract
This paper designed an experiment for exploring the effect of the artificial light source on the rice seedling quality under closed stereoscopic cultivation. The experiment which the rice seedling of Dongnong 428 variety was conducted in the closed seedling breeding room with the automatically controlled environment. The factors examined included fluorescent lamp (TFL), LED fluorescent light (W), LED red light (R), LED blue light (B), and three different combinations of LED red light and LED blue light (R:B 3:1, R:B 5:1, R:B 7:1) in the experiment for cultivating the rice seedling. The cultivated rice seedling was compared with that cultivated using natural light (NL). An analysis method was proposed for evaluating the physiological index, the morphological index, and the mechanical index of the rice seedling. The comparison results from the average values of various quality indexes of rice seedling showed that the growth strength order of the rice seedling under different light conditions was W > NL > TFL > RB > R > B. Therefore, it is feasible to use artificial light instead of natural light to cultivate rice seedlings, which is more effective and practical than the conventional breeding practice.
