陇东干旱区复种饲料油菜生产性能及营养分析

Production performance and nutritional analysis of multiple cropping fodder rape in Longdong arid area

试验研究在陇东干旱区复种的饲料油菜的生长适应性及营养价值变化。研究分析比较2个饲料油菜的生育期、农艺性状情况,结合气候因素对2个品种的营养成分进行比较。结果显示,华油杂62的生育期比饲油2号早2~3 d。2个油菜的农艺性状各指标变化趋势基本一致,华油杂62部分指标优于饲油2号。气候因素对其营养成分没有影响,决定营养成分的因素是品种。试验表明,华油杂62适宜在干旱区种植推广。

The experiment studied the growth adaptability and nutritional value change of fodder rape with multiple cropping in Longdong arid area.The growth period and agronomic traits of two fodder rapes were compared and analyzed,and the nutritional components of the two varieties were compared in combination with climate factors.The results showed that the growth period of Huayouza 62 was 2〜3 d earlier than that of Siyou 2.The change trends of agronomic traits of the two rape were basically consistent,and some indexes of Huayouza 62 were better than Siyou 2.The climatic factors had no effect on its nutritional composition,and the determining factor of nutritional composition was variety.The experiment indicates that Huayouza 62 is suitable for planting and popularizing in arid area.
