摘要
为了优化测土配方施肥技术参数,完善肥料配方,特进行了不同配方施肥及空白区的田间对比试验。结果表明,配方(1)施肥区的氮、磷、钾有效成份单位利用率分别高于配方(2)施肥区2.2%、24%、131%。但边际效益配方(2)施肥区高于配方(1)施肥区。
The results of formula fertilization showed that the unit utilization efficiency of nitrogen,phosphorus,and potassium in formula 1 was higher than that in formula 2 by 2.2%,24%,and 131%,respectively,but the marginal benefit of formula 2 was higher than that of formula 1.
