| 摘 要： | 为获得甘肃中部地区旱作种植条件下合理的苜蓿收割制度参数,在陇西县文峰镇典型黄土高原丘陵山地,以秋眠级5级的三得利苜蓿为例,研究不同刈割次数与苜蓿产草量、鲜干比、茎叶比、越冬性能以及营养物质含量等几个主要经济性状的关系。结果表明:在保证苜蓿正常越冬的条件下,每年刈割4次和3次处理组比每年刈割2次的处理组产草量提高7.13%和7.35%(P<0.05)。综合考虑收割成本,每年以收割3次为宜。

| Abstract: | In order to obtain harvest parameters of alfalfa under aerobic planting conditions in central Gansu area,specially at hills of loess plateau in Zhongshan,Longxi county,the relationships of Suntory alfalfa with 5 grade were studied between mowing times with yield,fresh-to-dry ratio,stem-leaf ratio,overwintering performance,nutrient content and other major economic characteristics.The results showed that under the condition of normal overwinter,mowing 4 or 3 times a year had higher yield of 7.13%and7.35%(P<0.05)than mowing two times a year.If considering the harvest cost,it is recommended to harvest three times a year. |
