Abstract: Using field plot experiment, the influences of film mulching and permanent-bed-planting leguminous crops on growth, yield and quality of Chinese cabbage were studied. The results showed that in comparison with traditional planting method, film mulching, permanent-bed-planting soybeans, and film mulching + permanent-bed-planting soybeans all can improve the chlorophyll content, net photosynthetic rate, yield and quality of Chinese cabbage leaf, and film mulching especially can improve the yield of Chinese cabbage. Among them, yield improved by 130.7%, 7.2% and 17.3%, respectively; Chlorophyll increased by 7.4%, 9.2% and 10.3%, respectively;net photosynthetic rate improved by 42.6%, 39.9% and 39.2%, respectively; vitamin C improved by 6.1%, 33.3% and 39.4%, respectively;soluble sugar increased by 18.6%, 14.3% and 22.5%, respectively; nitrate reduced by 7.5%, 25.0% and 25.0%, respectively.
