摘要
应用灰色系统理论中关联度分析法,通过株高、分枝、叶重、鲜草产量、粗蛋白、粗纤维、粗脂肪等性状指标对同仁地区7种紫花苜蓿品种的生产性能进行综合评价。结果表明,金皇后(ri=0.7667)、甘农三号(ri=0.7231)综合生产性能最好,公主岭苜蓿(ri=0.5665)综合生产性能最差。
By the gray relevancy analysis method of the gray systematic theory, the production performance in Tongren area of 7 Medicage sativa euhivars were evaduabed using plant height, branch number, leaf yield , fresh forage yield protein, fibr and fat . The results indicated that in the Tongren area, cuhivars ineluding Golden Empress （ ri= 0.7667）, C, annong NO. 3 （ ri = 0.7231 ） had good productivity, while Gongzhuling alfalfa（ ri = 0.5665）had low productivity.
