Effects of quinhydrone, as urease inhibitor, on growth, root activities, nitrogen metabolism, photosynthetic character, yield as well as quality were studied under pot experiment with water spanich and plot experiment with B.chinensis Var.comrtzunis. The results were shown as follow: 1. Applying low and medium amount quinhydrone promoted the growth of water spanich and B.chinensis Va,communis, whereas high amount treatment had little effect on water spanich growth, and inhibited the growth of B.chinensis Var communis.
