优良杂交黄皮洋葱品种,全生育期280天左右,冬性强、品质好、产量高,667平方米产量达4000千克。现就栽培关键技术介绍于后:一、适期播种适期播种是夺取高产的关键环节。播期过早,越冬前葱苗粗大容易通过春化,抽薹率高;播期过晚,幼苗弱小而不能及时移栽,越冬抗寒能力差、死苗率高 Good hybrid yellow onion varieties, the whole growth period of about 280 days, strong winter, good quality, high yield, 667 square meters output of 4000 kg. Now on the cultivation of key technologies introduced in the future: First, the right sowing sowing is to seize the key to high-yielding links. Sowing too early, before the winter thick green onion easily through vernalization, bolting rate is high; sowing too late, the seedling is weak and can not be transplanted in time, poor winter hardy cold, dead seedling rate
