摘要
在内蒙古土默川山前洪积平原水肥条件不同的土壤上,对引进不同燕麦品种的产量及其构成因素进行了相关及聚类分析。结果表明:供试燕麦品种之间的产量有极显著差异。株高只在水肥条件较差的情况下与草产量显著相关。在两种条件下,燕麦的草产量与子粒产量均呈显著相关;子粒产量主要取决于穗重、穗粒数。而在水肥条件较好的情况下,千粒重、穗数、穗重、穗粒数与子粒产量均显著相关。不同品种间,皮燕麦坝莜4号和科燕1号产量较高,坝莜4号的抗逆性较强;裸燕麦比皮燕麦对水肥条件敏感。
Correlation analysis and cluster analysis of yield and yield components of different oat varieties in the soil of different water and fertilizer conditions in the alluvial plains of Inner Mongolia Tumochuan were used to evaluate the differences of yield and yield components among different oat varieties.The results showed that there was a very significant difference in the yield and yield components among different oat varieties.There was significant correlation between the height and grass yield only when the water and fertilizer condition were poor.There was significant correlation between oat grass yield and grain yield in the two conditions,indicating that the grain yield depends on panicle weight and grain number per spike.Meanwhile,there were significant correlations between 1000-kernel weight and yield,spike number and yield,panicle weight and yield,grain number per spike and yield.Skin oats ＂Bayou 4＂ and ＂Keyan 1＂ had higher yield and the former had high stress tolerance.Naked oats were more sensitive to water and fertilizer conditions than skin oat.
