山西省莜麦主要分布于高寒山区。现根据近年来莜麦亩产400—638斤的高产典型和大面积亩产200斤以上的经验,提出莜麦翻番的几项栽培技术。一、依不同生态区域,做到优良品种的合理布局。(一) 土石山区:此类地区年平均气温在3—5.4℃,无霜期90—110天,年降雨量为400多毫米,气候凉爽,耕地零散,耕作粗放。应种植抗旱性强、生育期短、适应性广的雁红14号、晋燕2号莜麦为主。沟洼高肥地应以抗倒、生育期短、矮秆品种737-01、738-64-2为搭配品种。(二) 黄土丘陵区:此类地区无霜期在120天左右,年降雨量450多毫米,地广人稀,土壤瘠薄。应以前期生长发育缓慢待雨的抗旱品种晋燕4号、雁红10号为主。河湾二阴下湿地以抗旱、秆粗、增产潜力大的74028-28为搭配品种。(三) 平川区:此类地区年平均气温6.2—7.2℃,无霜期120—130天,降雨量360—400毫米,土壤平坦肥沃,水利资源较为丰富,应以738-64-2为主,中水肥地以雁红13号、74028-28为搭配品种。
Shanxi oats are mainly distributed in the alpine mountains. According to recent years, 莜 亩 400-638 pounds per mu yield of high-yield typical and large-area mu of more than 200 pounds of experience, put forward several doubling 莜 wheat cultivation techniques. First, according to different ecological regions, to achieve a reasonable layout of fine varieties. (I) Rocky Mountain Areas: The annual average temperature in these areas is 3-5.4 ℃, the frost-free period is 90-110 days, the annual rainfall is more than 400 mm, the climate is cool, the arable land is fragmented and the extensive farming is carried out. Should be planted drought-resistant, short growth period, wide adaptability Yanhong 14, Jin Yan 2 oats based. Ditch depression should be high fat to fight down, short growth period, dwarf varieties 737-01,738-64-2 with varieties. (II) Hilly Loess Plateau: The frost-free period in such areas is about 120 days with an annual rainfall of over 450 mm. The area is sparsely populated and the soil is barren. Should be the early growth and development to be rain-resistant varieties of drought Yan Yan 4, Yan-10-based. River Bay two Yinxia wetlands to drought, stalks, large yield potential of 74028-28 with varieties. (Three) Hirakawa: annual average temperature of 6.2-7.2 ℃ in such areas, frost-free period of 120-130 days, rainfall 360-400 mm, flat and fertile soil, water resources are more abundant, should be mainly 738-64-2, medium Water and fertilizer to Yanhong 13, 74028-28 with varieties.
