不同品种燕麦在扬州地区的生产性能

Productive performance comparison of different oat varieties in Yangzhou region

本研究以8个不同品种的燕麦(Avena sativa)作为试验材料,从物候期、农艺性状和牧草品质等方面进行综合探究,以期筛选出适合南方种植的优良燕麦品种。结果表明,各品种燕麦均在4月中旬进入抽穗期,但不同品种燕麦的各项指标间均存在着差异,收获期枪手的植株高度和干草产量均为试验组最高,贝勒鲜草产量最高,小马粗蛋白含量最高,林纳粗脂肪含量最高,各燕麦品种间尤以粗脂肪含量的差异最为明显。目前国内常用蛋白质产量作为牧草生产性能的评价指标,本研究中品种林纳的蛋白质产量为810.94kg·hm-2,为试验品种中最高。因此,从生育期和蛋白产量来看,燕麦林纳在该区域冬闲田利用中更具有利用价值和潜力。

The aim of this study was to screen out the best oat varieties suitable for planting in the Yangzhou region.To comprehensively investigate the production performance,eight different varieties of oats were used as experimental materials.The results showed that all the oat varieties reached the heading stage during midApril,but there were some differences among some indexes（phenology,agronomic traits,yield,and quality of forage）of different varieties of oats.At harvest stage,plant height and hay yield of Qiangshou were the highest in the experimental group.Fresh grass production of Baler,crude protein content of Xiaoma,and ether extract content of Rinne were also the highest at harvest stage.However,the differences in ether extract content among the oat varieties were highly significant.The current domestic protein yield is used as an evaluation index for the performance of herbage.The protein yield of oatmeal was 810.94 kg·ha^-1,which was the highest among the tested varieties.Therefore,in terms of growth period and protein yield,Rinne has more potential for utilization in the winter fallow fields in the Yangzhou region.
