摘要:

【目的】明确不同燕麦品种农艺性状及饲草品质对其再生产量的影响,为燕麦再生研究与生产实践提供参考。【方法】以41个燕麦品种为试验材料,在燕麦抽穗期刈割,对燕麦农艺性状(株高、旗叶叶面积、饲草干物质量),饲草品质性状(粗蛋白、粗脂肪、可溶性糖)及再生力、再生产量进行统计分析,并采用模糊数学隶属函数法综合评价燕麦的再生产力。【结果】燕麦抽穗期刈割,株高、旗叶叶面积、饲草干物质量的变异系数为15.68%~22.83%;饲草粗蛋白含量、粗脂肪含量、可溶性糖含量的变异系数为8.11%~23.46%;再生力、再生产量变异系数分别为31.75%、24.12%。相关性分析表明,旗叶叶面积与再生产量呈显著正相关(P<0.05),粗蛋白含量、粗脂肪含量、可溶性糖含量均与再生产量呈极显著正相关(P<0.01),再生力与再生产量呈极显著正相关(P<0.01);通过模糊数学隶属函数法对燕麦8个性状指标综合评价,前10位的品种为莫妮达、白燕7号、奥塔、蒙特、蒙燕1号、魁北克、贝勒、青引3号、甜燕2号、内燕5号,莫妮达、白燕7号综合性状最优、再生力强、品质高且再生产量较大,综合评价的平均值分别为0.89、0.87。【结论】燕麦抽穗期刈割,粗蛋白含量、粗脂肪含量、可溶性糖含量与再生产量呈正相关关系,再生力较强的燕麦品种为莫妮达、白燕7号、奥塔、蒙特、蒙燕1号、魁北克、贝勒、青引3号、甜燕2号、内燕5号。

Abstract:

【Objective】The effects of agronomic traits and forage quality of different oat varieties on their regeneration yield were clarified,which provided reference for the follow-up research and production practice of oat regeneration.【Methods】Taking 41 oat varieties as research materials,cutting at the heading stage of oats,the agronomic traits(plant height,flag leaf area,forage dry matter quality),forage quality traits(crude protein,crude fat,soluble sugar),regeneration capacity,and regeneration yield of oats were statistically analyzed,and the fuzzy mathematics membership function method was utilized to thoroughly evaluate the reproduction ability of oats.【Results】The coefficient of variation of plant height,flag leaf area and forage dry matter quality of oats cut at heading stage was 15.68%-22.83%.The coefficient of variation of crude protein content,crude fat content and soluble sugar content was 8.11% to 23.46%. The coefficient of variation of regeneration capacity and regeneration yield were 31.75% and 24.12%,respectively. The results of the correlation study revealed a positive correlation between the area of the flag leaf and the regeneration yield(P<0.05),a extreme positive correlation between the crude protein,crude fat,and soluble sugar contents and the regeneration yield(P<0.01)as well as a extreme positive correlation between regeneration capacity and regeneration yield(P<0.01). The top 10 species of oat,as determined by the thorough examination of 8 oat character indexes using fuzzy mathematics membership function method,were Monida,Baiyan No. 7,Aota,Mengte,Mengyan No. 1,Kuibeike,Beile,Qingyin No. 3,Tianyan No. 2 and Neiyan No. 5. Among them,Monida and Baiyan No. 7 had the best comprehensive characters,with strong regeneration capacity,good quality traits,and high regeneration yield. The full evaluation average value was 0.89、0.87.【Conclusion】When the oats were cut at heading stage,the crude protein content,crude fat content and soluble sugar content were positively correlated with the regeneration yield. The oat varieties with better regeneration capacity were Monida,Baiyan No. 7,Aota,Mengte,Mengyan No. 1,Kuibeike,Beile,Qingyin No. 3,Tianyan No. 2 and Neiyan No. 5.
