摘要
试验于１９９５～１９９６年在辽宁省彰武县沙地低产草地上进行，设氮、磷、钾混施和单施氮肥两组试验。结果表明，不论是混合施肥还是单一施肥，对低产沙地草地都有增产效果，但混合施肥较单一施肥增产效果显著，增产幅度达２５３．３％～３０６．６７％，混合比例以１∶０．６４∶０．
fertilizer application trial was conducted on the sandy grassland in Zhangwu county during 1995～1996. The results showed that application of chemical fertilizers of N, P and K, either as single component fertilizer or as compined composite fertilizer, could greatly improve the productivity of the sandy grassland. Combined fertilizer application had a more obvious growth promoting effect than single component application, a 253.3% ～306.7% yield increase from the combined application treatment was obtained. The best combination rate was found to be N∶P∶K=1∶0.64∶0.6.
