研究了不同播量(31.5,45.0和58.5 kg/hm2)和不同刈割次数(每年1次,每年2次,每年3次)对老芒麦(Elymus sibiricus )栽培草地草产量及品质的影响。结果表明：播量对老芒麦再生性能、草产量和粗蛋白质产量影响极显著(P <0.01),而对酸性洗涤纤维(ADF)和中性洗涤纤维(NDF)含量无显著影响,且各指标均在播量 D2(45 kg/hm2)处理下表现最好。刈割次数则对其都有极显著的影响(P<0.01),且各指标均在刈割次数 CF2(2次)处理下表现最好。两者的互作对再生强度、草产量和粗蛋白质产量影响极显著(P <0.01)。肃南牧区老芒麦人工草地的利用,在播量 D2(45 kg/hm2),刈割次数CF2(2次)为宜,不仅再生性能好、干物质产量和粗蛋白质产量高,而且品质好。

For studying the influence of different seeding rate and mowing frequency on the yield and quality of E .sibiricus ,the experiment with three kind of seeding rates and five kinds of mowing frequencies studied the regeneration performance,yield and quality(crude protein,acid drought fiber(ADF)and neutral drought fiber (NDF))of E .sibiricus .The result showed that there were the significant difference in the regeneration perform-ance,hay yield and crude protein under the different seeding rates(P <0.01 ),no signficant difference in ADF and NDF.The indicators were best under the seeding rate with the D2(45 kg/hm2 ).There were the signficant difference in the indictors under the the different mowing frequencies(P <0.01),the best performance were un-der the CF2(twice).Interactions between the seeding rate and mowing frequency had a high significant influence on regeneration intensity,hay yield of crude protein (P < 0.01 ).In general,the optimized combination of E . sibiricus in Sunan was the seeding rate (45 kg/hm2 )and the mowing frequency (twice per year).
