在百脉灵与3种禾本科牧草混播草地上研究了 N、P、K 不同施肥量对混播草地产量、品质和经济效益的影响。结果表明：在伊犁新垦区土壤肥力条件下,春季在混播草地上一次性施入尿素260 kg/hm2,过磷酸钙450 kg/hm2,硫酸钾120 kg/hm2为最佳施肥方案,不仅能促进混播草地牧草生长,提高了豆科牧草比例,改善牧草品质,还显著增加了混播草地的干、鲜草产量,比对照增产干草3042.7 kg/hm2,且增加净收入达1282.7元/hm2,产生了较好的经济效益；在 T2处理下混播草地产量达到最大值,但当施肥量持续增加至 T3处理时产草量不再增加,反而有下降趋势。

The effects of nitrogen,phosphorus and potassium fertilizer on yield,quality and economic effi-ciency of mixture pasture were studied.The result showed that the best fertilizing time was spring,and the suit-able fertilizing capacity was 260 kg of urea,450 kg of calcium superphosphaty,and 120 kg of potassium sulfate per hectare.The fertilization treatment not only increased the growth,proportion of legume forage,quality of forage,but also improved the hay yield by 3 042.7 kg/ha,and yearly net income by 1 282.7 yuan/ha.
