毛葱学名珠葱,主要产于东北。利用这种技术,葱平均产量为25.5t/hm~2,大豆平均产量为1750kg/hm~2。2004年黑龙江省宝清县夹信子镇夹信子村毛葱套种大豆栽培面积达253hm~2,产品已出口到日本和韩国。该地区已成为毛葱生产基地,多年来一直是毛葱套种秋菜,近两年发展到毛葱套种大豆。毛葱套种大豆,主要是利用毛葱生长期短,对光照反应不十分敏感这一特点,在栽培毛葱的垄沟内套种大豆,毛葱收获后大豆可正常生长,其产量与单种毛葱和大豆的产量差别不大。大豆选择早熟品种,生育期90～100d。主要栽培技
Onion bead onion scientific name, mainly produced in the northeast. With this technology, the average yield of onion is 25.5t / hm ~ 2 and the average yield of soybean is 1750kg / hm ~ 2. In 2004, the cultivation area of soybean intercropped with onion and intercropped soybean reached 253hm ~ 2 in Xiexinzi Village, Products have been exported to Japan and South Korea. The area has become an onion production base, over the years has been a spring onion intercropping autumn vegetables, in the past two years the development of onion intercropped soybean. Onion intercropping soybeans, the main is the use of onion growth period is short, very sensitive to the characteristics of the light response, the cultivation of onion ditch intercropping soybean, onion harvest after normal growth of soybean, the yield and a single onion Soybean production and little difference. Soybean selection precocious varieties, the growth period of 90 ~ 100d. The main cultivation techniques
