摘　　要：进行了四翅滨藜全年刈割1次、2次、3次和4次饲草生产对比试验。结果表明,四翅滨藜年刈割2次、3次可以获得较高的鲜草产量,单株鲜草产量分别为2713.2和2458.7g,年刈割2次鲜草产量是年刈割1次、4次的2.3倍和1.5倍。年刈割2次、3次的干草产量也较高,尤其以年刈割2次最高,单株干草产量可达1148.5g。随着刈割频率的增加,鲜干比不断上升,为年刈割4次>年刈割3次>年刈割2次>年刈割1次。Forage production was compared between Atriplex canescens which was cut once, twice, thrice and four times in a year. The results showed that the Atriplex canescens that was cut twice or thrice had higher grass yield per plant, 2 713.2 and 2 458.7 g, respectively. And the grass yield of Atriplex canescens which was cut twice was 2.3 times as high as that of Atriplex canescens which was cut once and 1.5 times as high as that of Atriplex canescens which was cut four times. The Atriplex canescens which was cut twice or thrice had high hay yield, and the former had the highest hay yield （1 148.5 g per plant）. With increasing cutting frequency, ratio of fresh weight to dry weight was also increased, and it decreased in such order： four times cutting〉 thrice cutting 〉twice cutting〉 once cutting.
