摘　　要：通过沼液与水不同比例配比追肥,研究沼液不同施用浓度对小白菜生物学性状和产量的影响。结果表明:在苗期后第35天,施用沼液低量处理的小白菜的叶片宽、叶片长和叶柄长比其他各处理高,分别为50.37、58.17、26.34mm;沼液中量处理的小白菜的叶片数为9.6片,高于其他各处理。施用沼液显著提高了小白菜的产量,其中沼液高量处理产量最高,达730.921kg/667m2,增产97.74%。Effects of anaerobic fermentation slurry of different concentrations on the biological characteristic and yield of Chinese cabbage were studied through experiments of anaerobic fermentation slurry as supply application with water at different ratio. The anaerobic fermentation slurry as an organic fertilizer had rich nutrient contents which were helpful to improve the biological characteristic of Chinese cabbage. At 35th day after seeding stage of Chinese cabbage, the leaf width, leaf length and petiole length of Chinese cabbage were 50. 37 mm, 58. 17 mm and 26. 34 mm, respectively, when the low concentration of the anaerobic fermentation slurry treatment was applied, which were higher than those of the other treatments. The highest leaf numbers of Chinese cabbage was 9.6 when the medium concentration of the anaerobic fermentation slurry was used. The yield of Chinese cabbage was enhanced remarkably by the supply application of anaerobic fermentation slurry. The highest yield of Chinese cabbage was 730. 921 kg/667m^2 when the high concentration of the,anaerobic fermentation slurry treatment was used and it was 97.74% higher than that of the control.
