摘要
研究为阿鲁科尔沁旗节水灌溉苜蓿人工草地轮作倒茬筛选优良燕麦品种。利用灰色关联度分析法对国内外引进的13个燕麦材料的株高、分蘖数、茎重、叶重、叶长、叶宽、干草产量、CP含量、RFQ值进行综合评估,通过对参试品种加权关联度的比较,较为全面、客观地评价了参试品种的优劣。明确了阿鲁科尔沁旗燕麦引种应优选考虑CP含量、叶宽、RFQ值、干草产量和株高表现突出的品种;边锋、坝燕4号、梦龙、林纳、冀张燕4号5个燕麦品种在生产性能和营养品质方面综合评价表现突出,可在科尔沁沙地作为苜蓿轮作倒茬首选燕麦品种推广种植。
Screening quality oats varieties for crop rotation of alfalfa artificial grassland with water saving irrigation in Aluke’rqin County was made. The plant height, tiller number, stem weight, leaf weight, leaf length, leaf width, hay yield,CP content and RFQ value of 13 Varieties were also evaluated with gray relational analysis.The results indcated that introduction oats should consider the varieties of CP content, leaf width, RFQ value, hay yield and plant height. Wing front,dam Yan 4, Meng Long, Linna, Ji Zhang Yan 4 with heigher nutritional quality and excellent comprehensive characteristics were more suitable to be extend as varieties of alfalfa crop rotation in Aluke’rqin County.
