| 摘 要： | 以玉米品种郑单958为试验材料,通过在试验种植小区的氮、磷、钾不同比例的施肥研究对比,探讨钾肥对玉米的增产效果。结果表明,试验地土壤氮、磷养分供应充足,钾是该类土壤的主要限制因子,应重施钾肥,进一步提高作物产量,以获得最大的经济效益。

| Abstract: | Taking Zhengdan 958 as material , the application effect of different ratios of NPK fertilizer on corn in test growing area was studied to discuss the yield-increasing effect of potassium fertilizer. Results showed that the supplies of nitrogen and phosphorus were adequate , and the potassium was the limiting factor of soil. It ' s proposed that potassium should be applied to promote the yield of crops and obtain maximum economic benefit. |
