摘  要：
通过田间试验研究了氮磷钾肥丰缺对大蒜产量及NPK元素利用率的影响.结果表明,相对常规氮磷钾全量施肥处理,缺施氮磷钾肥减少蒜薹和蒜头的产量,缺氮影响最大,缺磷次之,缺钾影响最小;同样,缺施氮磷钾肥会影响大蒜对N、P、K的利用率,缺施氮肥降低大蒜对P和K的利用率;缺施磷肥增加N的利用率,对K的利用率影响不大;缺施钾肥降低N的利用率,对P的利用率影响不大.

摘  要：
The effects of abundance and deficiency of nitrogen, phosphorus and potassium fertilizers on yield and NPK utilization efficiency of garlic were studied by field trial. The results showed that compared with the abundance NPK fertilizer, the application of deficiency NPK fertilizer reduced the yield of garlic bolt and garlic clove. Nitrogen deficiency had the greatest influence on garlic yield, and phosphorus deficiency was the second factor, while potassium deficiency had the least influence. Similarly, the lack of nitrogen, phosphorus and potassium fertilizers could affect NPK utilization efficiency of garlic. The lack application of nitrogen fertilizer reduced the P and K utilization rate of garlic. The lack application of phosphorus fertilizer increased the utilization rate of N and had little effect on K. The lack application of potassium fertilizer reduced the utilization rate of N and had little effect on P.
