摘  要：
【目的】针对伊犁河流域水土资源开发,研究不同施肥配比对人工混播草地产量及品质的影响。【方法】运用"3414"施肥方案设计,研究不同N、P、K配比施肥对混播草地第2年产量及营养成分的影响。【结果】试验得出,施N 66.01 kg/hm2、P2O585.03 kg/hm2、K2O 23.75 kg/hm2时,三茬干草的最高产量达到14 617.86 kg/hm2;影响混播草地产量高低顺序为N肥>P肥>K肥,粗蛋白质含量与豆禾比有明显的规律性,当豆禾比大时,其粗蛋白质含量高。【结论】N、P、K合理配比施肥,对混播草地产草量具有明显的效应作用,对改善牧草品质、提高混播草地生产力具有积极效果。

摘  要：
【Objective】Based on land and water resources development for the Ili River basin,the paper studied the effect of different ratio of different fertilizers on yield and quality of artificial mixed pasture.【Method】The test used "3414" fertilization program design,the effect of different N,P,K ratio of fertilization on the yield and nutrition of the second year mixed pasture were studied.【Result】Experiment showed that when fertilization is applied as the N 66.01 kg/hm2,P2O5 85.03 kg/hm2,and K2O 23.75 kg/hm2,the maximum yield of the three harvest hay reached up to 14 617.86 kg/hm2;the impact of fertilizer on the mixed pasture production is in the order of N fertilizer> P fertilizer> K fertilizer,crude protein content and the ratio of beans and grasses showed clear regularity.When beans and grasses ratio is large,there is a high content of crude protein.【Conclusion】Reasonable proportion of N,P,K fertilization has an obvious effect on mixed grassland yields.It has a positive effect in improving the forage quality and the productivity of mixed pasture.
