元葱是地域性很强的蔬菜,主要是受日照长短所制约。过去有人试图将我国关内的元葱引入我省栽培,但均未获成功。这是因为其光照条件得不到满足。作者选择与我省相近纬度的国外元葱品种,经过多年系统选育,终于育成适合我省长日照地区栽培的大庆元葱1号,填补了我省元葱育种的空白。 Yuancong is a very regional vegetables, mainly by the length of the sunshine. In the past, some people tried to introduce the green onions in our province into cultivation in our province, but none of them succeeded. This is because their lighting conditions are not met. The author chose a variety of foreign varieties of onion with similar latitudes to our province. After many years of systematic breeding, we finally developed Daqingyuancong 1, which is suitable for cultivation in our province’s long-sunshine region, and filled the gap in the cultivation of Yuancong in our province.
