摘  要：
为探明膜下滴灌对花生施肥农学效率及肥料利用率的影响,设膜下滴灌和传统栽培方式下施用不同肥料处理,利用差减法计算肥料利用率与农学效率。结果表明,膜下滴灌条件下,单独或配合施用氮、磷、钾肥处理的农学效率高于不滴灌处理;膜下滴灌单独施肥可提高氮利用率14.50%、磷利用率5.00%、钾利用率10.77%,配合施肥氮、磷、钾肥利用率分别提高17.20%、7.88%、16.62%。由此表明,膜下滴灌处理可以有效提高花生氮、磷、钾肥的农学效率和肥料利用率。

摘  要：
The objective of this study was to explore the effect of mulch drip irrigation on fertilizer agronomic efficiency and fertilizer utilization efficiency to peanut.The split plot drip irrigation and different fertilization treatments in the same area were adopted to calculate fertilizer utilization efficiency and agronomic efficiency by subtraction.The results showed that the agronomic efficiency of nitrogen,phosphorus and potassium alone or combined fertilization under drip irrigation condition was higher than that of non drip irrigation treatment,and the drip irrigation could increase the use efficiency of nitrogen,phosphorus and potassium as 14.50%,5%,and 10.77%respectively under alone fertilization,and 17.20%,7.88%and 16.62%respectively under combined fertilization.Drip irrigation could effectively improve the agronomic efficiency and fertilizer use efficiency of nitrogen,phosphorus and potassium to peanut.
