【摘要】 在华北农牧交错带 ,进行新麦草人工草地划区轮牧试验。结果表明 ,中牧区新麦草的分蘖数增多、叶面积增加迅速、再生速度加快 ,粗蛋白质含量提高、中性洗涤纤维和酸性洗涤纤维含量下降。中牧区有利于提高新麦草的产草量和品质改善。更多还原

【Abstract】 The study of production characters and quality under light grazing (LG),medium grazing (MG),heavy grazing (HG)and no grazing(CK)was carried out on a russian wildrye grass( Psathyrostachys juncea (Fishch)Nevski)pasture during growing season(mid June to mid September)in 1997.The results showed that plant height declined with increasing of the grazing intensity,while the tiller quantities increased;the more of the tiller number,the less of the tiller weight in russian wildrye grass under grazing.The order of leaf arears was CK>MG>LG>HG.The forage yield and the content of CP were increased,and the quality was improved,and the content of ADF,NDF were decrease under MG.更多还原
