本研究针对北疆沿天山一带麦后免耕复种饲用油菜生态适应性进行研究,分析了饲料油菜的生理特点、气候适应性及生态适应性。结果表明,饲料油菜能够在北疆沿天山一带的夏秋之交实现复种,复种饲料油菜能够适应夏季的高温,夏秋之交的昼夜温差大,秋季的温度下降快、热量不均衡,下霜后仍能正常生长。 In this study, we studied the ecological adaptability of rape after tillage and non-tillage rearing along the Tianshan Mountains in the northern part of the country and analyzed its physiological characteristics, climate adaptability and ecological adaptability. The results showed that the rapeseed could be double-cropped at the turn of summer along the Tianshan Mountains in the northern part of the country. The multiple-crop rapeseed could adapt to the summer high temperature. The temperature difference between day and night was large at the turn of summer and autumn, Can grow normally.
