摘　　要：以普通园田土为对照,研究了有机土栽培对小白菜产量和营养品质的影响。研究结果表明,采用有机土栽培的小白菜生长势强,根系活力高,光合速率大,较普通土栽培增产8.0%以上;同时有机土栽培的小白菜硝酸盐含量显著降低,降幅达33.9%,且有机土栽培的小白菜的营养品质包括粗蛋白含量、总糖含量均有不同程度的提高。这些结果表明,有机土栽培在减少小白菜的硝酸盐残留,提高小白菜产量与改善小白菜营养品质方面有明显效果,是实现蔬菜优质高产的新型栽培方式。Comparing to ordinary soil （CK）, organic soil substrate were used to cultivate pakchoi. The results indicated that the pakchoi grown in organic soil had higher root activity, the photosynthesis rate was 8.0% higher than CK. Meanwhile, the nitrate content in pakchoi grown in organic soil reduced by 33.9%; whereas, the pakchoi＇s dry material content, the crude protein content, the total sugar content were increased. So the organic soil cultivation will be useful to realize the high yield and high quality in protected horticulture.
