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.
