| 摘 要： | 对人工草地进行氮、磷、钾施肥试验表明:人工草地建植当年和翌年适宜的施肥组合分别为P50N100K150和P20N40。氮、磷组合的肥效显著高于单施氮肥和磷肥的肥效。建植当年人工草地每公斤纯磷可增加干草产量14.76公斤,建植翌年人工草地每公斤纯氮可增加干草产量17.92公斤。

| Abstract: | Effects of N, P, K fertilizers on sown pasture was studied. The results showed that appropriate fertilizers and their application rates were P (50), N (100), K (150), and P (20) N (40) in the first and the second year after sown. The yields were obtained from the plots received N and P was significantly higher than those from the plots received P or N only. One kg pure P increased dry matter yield by 14.76kg in the first year, and 1 kg pure N increased dry matter yield by 17.92kg in the second year after sown. |
