摘要
以白菜为试材，设6个处理，T1～T3处理分别为无机肥处理、有机无机肥配施处理和有机肥处理，以及在此基础上分别对应T1-T3处理，在莲座期和结球前期每垄施用1％浓度的石灰1600mL，为T4～T6处理，研究了商品有机肥与无机肥配合施用及单独施用对白菜产量和品质的影响。结果表明：T3、T6处理收获期硝酸盐含量分别较T1、T4处理下降了32．3％和35．2％；维生素C含量提高了30．0％和38．6％；可溶性糖含量升高了31．5％和34．5％。可见有机肥能够提高白菜品质，但对产量的贡献却不明显。而有机无机肥配施则能够在保证白菜品质的前提下，使产量提高2％～27％，与施用有机肥相比达到差异显著水平（P〈0．05）。施用石灰的处理各项指标均优于未施石灰的处理结果。说明均衡营养并配施有机无机肥能够起到提高白菜产量和品质的目的。
Taking Chinese cabbage as test materials, the dynamic change of quality and yield of Chinese cabbage under combination of organic and inorganic fertilizer with six treatments were studied. T1, T2 and T3 treatments were applied with inorganic fertilizer combination of organic and inorganic fertilizer and organic fertilizer,respectively. Base on these treatments,T4-T6 treatments were set with the application of 1% lime 1 600 mI. at rosette stage and early heading stage. The results showed that compared with T1 and T4 treatments,T3 and T6 treatments were reduced the content of nitrate by 32. 3% and 35. 2% respectively and increased the content of vitamin C by 30. 0% and 38. 6% also increased the soluble sugar content by 31.5% and 34. 5%. The organic fertilizer could increase the quality of Chinese cabbage but do little contribution to the yield. However,the combination organic and inorganic fertilizer increased the yield from 2% to 27 and showed significant difference （P〈0. 05） compared with the organic fertilizer treatments. The results of applying lime treatments were better than that of not applying lime. Under the condition of balancing soil nutrition and applying the combination of organic and inorganic fertilizer could improve the quality of the Chinese cabbage.
