燕麦农艺性状及品质分析

Analysis of Agronomic Characters and Quality of Oat

摘要:

为了筛选出产量高、品质好、适应旱作农业区推广的家畜饲草———燕麦(Avena sativa L.),对引进的3个燕麦品种进行生产能力及营养成分测定。采用因子分析法对3个品种12个农艺性状之间的相互关系进行综合评价分析,同时对不同品种间对应的常用营养成分指标进行方差分析。结果表明,福燕1号综合得分5.626,排名第1。3个品种之间“灰分”差异显著(P<0.05);多重比较结果显示,“非纤维淡水化合物”、“总可消化养分”和“单糖”甜燕1号与福燕1号之间差异显著(P<0.05),其余指标3个品种之间差异不显著(P>0.05)。

Abstract:

In order to select the forage of high yield,good quality and suitable for popularization in dry farming area,Oat(Avena sativa L.),the productivity and nutrient composition of 3 introduced varieties of Avena sativa L.were determined.The relationship between 12 agronomic traits of 3 varieties was evaluated by factor analysis,and variance analysis was performed for the common nutrient components of different varieties.The results showed that the comprehensive score of Fuyan No.1 was 5.626,ranking first.The “ash” of the three varieties was significantly different(P<0.05).The results of multiple comparisons showed that there were significant differences between “nonfiber freshwater compounds”,“total digestible nutrients” and “monosaccharides” between Tianyan 1 and Fuyan 1(P<0.05),but no significant differences among the other three indexes (P>0.05).
