摘　　要：为实现响水县小麦化肥减量增效,推广测土配方施肥技术,特进行3个年度的小麦氮、磷、钾肥利用率试验。结果表明,相对于常规施肥,测土配方施肥技术的氮肥利用率提高3.10~5.47个百分点,磷肥利用率提高3.83~6.23个百分点,钾肥利用率提高1.30~8.48个百分点。In order to increase the efficiency of wheat chemical fertilizer in Xiangshui County,and promote the technology of soil testing and formulated fertilization,three years of experiments on the utilization rate of nitrogen,phosphorus and potassium fertilizer for wheat were carried out.The results showed that compared with conventional fertilization,the nitrogen utilization rate of soil testing and formulated fertilization technology increased by 3.10-5.47 percentage points,the phosphorus utilization rate increased by 3.83-6.23 percentage points,and the potassium utilization rate increased by 1.30-8.48 percentage points.
