| 摘 要： | 通过田间小区试验,在2种土壤和2个季节条件下研究了3种硝化抑制剂,氢醌(HQ),双氰胺(DCD)和硫脲(TU),对小白菜产量和某些品质的影响。结果表明,与对照相比,3种硝化抑制剂均能不同程度提高小白菜产量,尤以双氰胺的增产效果最显著,达10%左右;且3种硝化抑制剂在红菜园土上的增产效果均比冲积菜园土上显著。3种硝化抑制剂均不同程度地提高了小白菜对氮和磷的吸收,对钾没有明显影响。3种硝化抑制剂均能明显提高小白菜维生素C(Vc)含量,但只有双氰胺和氢醌能明显提高小白菜的可溶性糖含量。

| Abstract: | The effects of 3 kinds of nitrification inhibitors application,Hydroquinone(HQ),Dicyandiamide(DCD) and Thiourea(TU),on yield and some nutrition qualities of pakchoi with plot experiment in 2 kinds of vegetable soils and at 2 kinds of growing seasons.The results demonstrated that 3 kinds of inhibitors,HQ,DCD and TU,all increased the yield of pakchoi to some extent,and of them DCD was the best.The yield of pakchoi in red vegetable soil was higher than that in alluvial vegetable soil.3 kinds of nitrification inhibitors could all increase N and P uptake obviously,while they did not affect K uptake by pakchoi.All the inhibitors could increase Vitamin C(Vc) contents of pakchoi,while only HQ and DCD increased the soluble sugar contents of pakchoi. |
