| 摘 要： | 小麦施用钾肥后产量显著增加，经济效益十分明显。土壤基础养分较高时，K2O施用量为135kg／hm^2时小麦产量最高，较对照增产770kg／hm^2，增产率15．0％；土壤基础养分较低时，K2O施用量为90kg／hm^2时小麦产量最高，较对照增产688kg／hm^2，增产率19．9％。

| Abstract: | The wheat yield and economic efficiency could be increased after applying potassium fertility.When the basic nutrient contain was high,the optimum fertilization was 135 kg/hm 2.The wheat yield increased 770 kg/hm 2 compared with the control,the increment ratio was 15.0%.When the basic nutrient contain was low,the optimum fertilization was 90 kg/hm 2.The wheat yield increased 688 kg/hm 2 compared with the control,the increment ratio was 19.9%. |
