摘要
盆栽小白菜施用氮、锌、锰肥研究结果表明：在本试验条件下，氮与锌、锰配合施肥，有利于提高小白菜体内营养元素的浓度，为提高产量和改善品质奠定了基础。施用氮、锌、锰肥均能使小白菜产量明显提高，尤其是氮，而且氮与锌、锰之间存在着明显的加合作用。
The experiment was conducted on calcareous cinnamon soil of Shanxi province with design of ordinary second order rotatable regression of three factors. Under the condition of pot experiment, combined application of uren, zinc sulfate and manganese sulfate to chinese cabbage was studied for it effects on elements content and yield of cabbage. The results were concluded as fallows:(1). Under the condition of this experiment, the content of uptake and utilization for N, P, Zn and Mn increased with the application of proper amount. It provided nutritional foundition for high yield and quality. (2). Application of Zn and Mn, especially N fertilizer, thd cabbage yield can be increased signficatiy, while the interaction between N and Zn, N and Mn, was most significant.
