采用田间小区试验，研究地膜覆盖和厢沟种植豆科作物对小白菜生长、产量和品质的影响。结果表明，与传统种植模式相比，地膜覆盖、厢沟种植大豆、地膜覆盖+厢沟种植大豆均能提高小白菜叶片中叶绿素含量、净光合速率、产量以及品质，且地膜覆盖更能提高小白菜产量。其中，产量提高幅度分别为130.7%、7.2%和17.3%；叶绿素提高幅度分别为7.4%、9.2%和10.3%；净光合速率提高幅度分别为42.6%、39.9%和39.2%；维生素C提高幅度分别为6.1%、33.3%和39.4%；可溶性糖提高幅度分别为：18.6%、14.3%和22.5%；硝酸盐降低幅度分别为7.5%、25.0%和25.0%。

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 i...
