油菜是甘南的主要油料作物,目前占全州总播面积的7％,占全省油菜面积的12％。甘南高寒阴湿,以农牧区的合作为例,地处北纬35°,海拔2936米,无霜期40余天,年均气温1.8℃,6月上旬气温才能稳定在10℃以上,持续100天左右,7月底气温最高,可达17℃以上,但仅能维持2天。因此,能在本地生长的小油菜必须生育期短,积温需要少,并
Rape is the main fuel crop in Gannan, which currently accounts for 7% of the total sown area in Quanzhou and 12% of the province’s canola area. Gannan alpine wet, with the cooperation of agriculture and pastoral areas, for example, is located 35 degrees north latitude, 2936 meters above sea level, frost-free period more than 40 days, the average annual temperature of 1.8 ℃, the temperature in early June to be stable above 10 ℃ for 100 days, The highest temperature at the end of July, up to 17 ℃ above, but only for 2 days. Therefore, small rapeseed that grows locally must have a short growth period, less accumulated temperature, and
