摘　　要：为探讨鸭茅在梨园较优的种植模式,通过不同播种量及行距处理,对梨园种植鸭茅产草量及相关性状的差异性进行了研究。结果表明:高播种量处理产草量高,播种量相同的处理产草量差异性均不显著;前期分蘖数都很少,到中期低播种量和中等播种量,行距越大分蘖数越多,高播种量处理分蘖数较少,到后期低播种量的处理分蘖数均较多;各处理在不同测定时间表现出的差异性规律性不明显。说明,高播种量和大行距是鸭茅在梨园较理想的种植模式。The effect of seeding rate and row spacing on yield and correlated characters of cocksfoot were studied to explore the superior orchard cultivation mode of cocksfoot.Results showed that the grass yield was proportional to seeding rate,there were no significant differences of grass yields between treatments with the same seeding rate.The tiller numbers of all treatments were very small in the early stage,but the tiller numbers of treatments with low seeding rate and moderate seeding rate were proportional to row spacing in the middle stage,the tiller number of treatment with high seeding rate was very small.All of the treatments with low seeding rate reached high tiller numbers in the last stage.There was no significant regularity of all treatments at different determining time.In general,the high seeding rate and wide row spacing were the ideal orchard cultivation mode for cocksfoot.
