沟播栽培,在干旱、低温、土壤瘠薄的低产地区,对增强冬小麦抗逆性、稳产性,提高产量效果显著。我地区在甘肃东部,习称陇东。本区地处黄土高原,位于北部冬麦区西北边缘。海拔1400米上下,年平均气温7～10℃,1月份平均气温零下5～7℃,极端最低气温-22.6℃。中北部年降水量400～500毫米。土壤肥力低下,有机质0.84%。冬小麦是本区主要作物,占粮作面积60%以上,以旱作为主。旱灾频
Sowing cultivation, in drought, low temperature, infertile soils, low yield areas, to enhance the winter wheat stress resistance, stable yield, increase yield significantly. My area is in eastern Gansu, Xi said Longdong. The area is located in the Loess Plateau, northwest winter wheat area located in the north edge. 1400 meters above sea level, the annual average temperature of 7 ~ 10 ℃, the average January temperature of minus 5 ~ 7 ℃, the extreme minimum temperature of -22.6 ℃. In the north of the annual precipitation 400 ~ 500 mm. Soil fertility is low with 0.84% organic matter. Winter wheat is the main crop in this area, accounting for more than 60% of the total grain crop area. Drought frequency
