| 摘 要： | 通过盆栽试验,探讨了石灰性褐土上氮与钾肥配施对莴笋(Lactuca sativa L. var. angustana Irish)产量和品质的影响。结果表明:单施适量氮肥对莴笋有一定的增产作用,但当每kg土氮用量超过0.30g时,反而导致减产。在施用氮肥的基础上配施钾肥,不仅能显著地提高莴笋产量,而且能明显减少施氮对品质造成的不利影响,氮、钾之间表现出良好的交互作用。

| Abstract: | In order to study the effectiveness of N and K fertilizers on yield and quality of lettuce (Lactuca sativa L. var. angustana Irish),the pot experiments were carried on calcareous cinnamon soil. The results showed that the yield of lettuce were enhanced in the treatment of only N fertilizer,but significantly decreased in the treatments which N applied amounts was over 0.30gN kg. Combined application of N and K fertilizers with proper ratioes significantly enhanced and improved the yield and quality of of lettuce. |
