摘　　要：对叶龄诊断技术施肥法和常规施肥法的不同施肥量的产量进行比较试验,结果表明:叶龄诊断法比常规施肥法增产3%。在施N 70.5 kg/hm2、P2O5 47.0 kg/hm2、K2O 23.5 kg/hm2时,叶龄诊断法产量最高达到8 402.4 kg/hm2。An experiment was carried out to compare the yield difference between leaf-age diagnostic and conventional fertilization techniques, and the results indicated that leaf-age diagnostic technique could result in 3% yield increase more than conventional method. The application of 70.5 kg/hm^2 of N, 47.0 kg/hm^2 of P2O5, and 23.5 kg/hm^2 of K could lead to the highest yield, 8 402.4 kg/hm^2.
