年刈割次数对科尔沁沙地不同秋眠级紫花苜蓿品种产量、品质和越冬率的影响
|
摘要
为明确科尔沁沙地适宜种植苜蓿秋眠级和刈割次数,在内蒙古阿鲁科尔沁旗以不同秋眠级的6个紫花苜蓿(Medicago sativa)品种为试验材料,研究不同秋眠级苜蓿品种刈割2次、3次和4次对产量、品质和越冬率的影响。结果表明,随刈割次数的增加,不同秋眠级苜蓿品种越冬率逐渐降低;秋眠级1～3级苜蓿品种年刈割3次总产量最高,秋眠级4～5级苜蓿品种年刈割4次总产量最高;不同刈割次数各茬次间苜蓿品质不同。综合分析得出,在科尔沁沙地灌溉苜蓿种植区,选择秋眠级1～4级的苜蓿品种,年刈割2～3次为宜。
In order to determine a fall dormancy rating and cutting times in Keerqin sandy land,the different fall dormancy rating of six alfalfa varieties were used for experimental materials in Aluke'rqin Banner,Inner Mongolia.To study the effects of two,three and four of cutting times on quality,yield and winter survival rate of the different fall dormancy rating alfalfa.The results showed that with the increase of cutting times,the winter survival rate decreased gradually of the different fall dormancy rating alfalfa;yield of three cutting times was the highest in fall dormancy rating alfalfa of 1 to 3,yield of four cutting times was the highest in fall dormancy rating alfalfa of 4 to 5;the quality was different in every cutting of different cutting times.In Keerqin sandy land of planting irrigation alfalfa areas,selecting alfalfa with fall dormancy rating 1 to 4,2 to 3 cutting times.
