| 摘 要： | 刈割是苜蓿的主要利用方式,刈割次数不仅影响紫花苜蓿Medicago sativa的当年草产量及营养价值,而且对其安全越冬和持久利用具有重要的影响。肇东苜蓿是哈尔滨地区苜蓿主栽品种,确定合理的刈割次数对紫花苜蓿的生产有重要意义。对肇东苜蓿进行了连续2年的不同刈割次数的田间试验,结果表明,种植第2、3年的肇东苜蓿的最优刈割次数是2006年(种植第2年)刈割2次,2007年(种植第3年)刈割2次;肇东苜蓿2006年(种植第2年)刈割次数与2年间总生产能力呈显著负相关,并且起了最主要和最直接的作用。

| Abstract: | Cutting is the main harvesting way for alfalfa and the cutting frequency affects not only the hay yield and quality but also the over-wintering rate. Medicago sativa cv. Zhaodong is the main variety in Harbin and it is important to determine its cutting frequency for the alfalfa production. In two-year cutting experiment, the hay yield, crude protein yield and over-wintering rate were measured. The data of different cutting treatments were comprehensively evaluated by the gray relevancy analysis method. The results indicated that the proper cutting frequency in Harbin was 2 times per year. The correlation analysis result indicated that the cutting frequency significantly negative correlated with the productivity. |
