试验以测土配方施肥与等纯N量习惯施肥和空白对照(不施肥)作比较，先按测土配方施肥步骤计算施肥量，再以纯N量按N：P2O5： K2O比例法计算习惯施肥的施肥量。结果表明，配方施肥每667m2产量最高，习惯施肥次之，增产差异明显。配方施肥大薯多具较强的推广价值。

In this test, compared the testing soil for formulated fertilization and the pure N quantity habits such as soil fertilizer and fertilizer and ck (no fertilizer). First step is calculating the fertilizing amount according to testing soil for formulated fertilization, and then calculate the fertilizing amount of conventional fertilization as pure N quantity according to the N:P2O5: K2O ratio method. The results show that the highest production is fertilizing per 667 m2, the conventional fertilization is the second, and the yield difference is obvious. Formulated fertilization yam have higher promotion value.
