| 摘 要： | 在豫西褐土区研究了钾、锰肥配合施用对旱地冬小麦的养分吸收与产量的影响。结果表明，钾、锰肥配施影响小麦体内氮、磷、钾的含量及吸收量。施用钾、锰肥小麦体内氮、磷含量均低于相应的对照(CK)，其中氮较为明显；钾含量则高于相应的对照。灌浆期氮、钾吸收量与产量有显著的相关性，在一定范围内，养分吸收量和产量均随钾、锰肥用量的增加而增加。

| Abstract: | Effect of potassium (K) and manganese (Mn) fertilizers cooperating application on nutrient uptake and yield of winter wheat in dryland at the cinnamon soil area in western He''nan Province were studied.The results showed that the nitrogen (N),phosphorus (P) and K content and uptake of winter wheat were affected by N in combination with Mn fertilizers application.With the K and Mn fertilizers application,the N,P content decreased compared to CK.Especially,the N content decreased significantly.Whereas the K content increased compared to CK.The correlation of the amount of N and K absorbed with yield was significant in the period of grain-filling.The nutrient uptake and yield increased with the increasing K and Mn fertilizers application in a certain range. |
