摘　　要：在准噶尔盆地北缘平原区土壤ｐＨ值为８．４５的生境条件下通过９年豆科牧草引种试验，证明百脉根在抗热、抗病虫害、耐涝性和使用年限方面优于其它豆科牧草，并证实了百脉根自然繁衍的种性特点和具有自然更新复壮、防止草场退化的能力；由百脉根更新的草场提高产草量２倍以上，粗蛋白质、粗脂肪分别提高７倍以上和４倍；用百脉根补播改良灌溉草场简单易行，适宜牧区生产条件，在我国南北方适宜地区具有广阔的推广前景。A experiment with legumes was made in Northern belts with pH 8.45 in ZhunGer basin fOr nine years.It was proved that disease一resistant,hot一 tolerance,flood一enuring and longivity of Lotus corniculatus were higher than that of other species.It also has more capacity of reproductivity,which is important to prevent pastures from degration.Forage yields in the pastures improved with the species doubled, and crude proteins and crude fats could be also increased by 7 and 4 times,respectively.A simple methods which can be used for resowing and improving irrigation pastures were proposed.The species will be have a promising prospects in the proper location of North or South of China when it is extended.
