我省甜菜产地河西三地区有耕地1000万亩,河水、井水灌溉的干旱区占50％以上。干旱区位于腾格里沙漠西南,祁连山以东,海拔1400—1700米,日照时数2300—2950小时,年平均气温6—7.5℃.≥0℃积温2900—3400℃,≥10℃积温2200—2900℃,无霜期120—150天,年降水量110—180毫米,年总蒸发量1200—2100毫米,干燥度为2—3.3(>2的干燥度为旱区)。土质属碱性,有机质1.3％,全氮0.08％,碱解氮50ppm,速效磷12ppm,速效钾180ppm。概括地说,海拔较高,气候干燥,蒸发量大,雨量稀少,
There are 10 million mu of cultivated land in the three areas of Hexi, the beet producing area in our province. The arid area where water and well water are irrigated accounts for more than 50%. The arid zone is located in the southwest of the Tengger Desert, east of the Qilian Mountains, elevation 1400-1700 meters, sunshine hours 2300-2950 hours, the average annual temperature of 6-7.5 ℃. ≥ 0 ℃ accumulated temperature 2900-3400 ℃, ≥ 10 ℃ accumulated temperature 2200- 2900 ℃, frost-free period 120-150 days, annual precipitation 110-180 mm, annual total evaporation 1200-2100 mm, dryness 2-3.3 (> 2 dry arid areas). Soil is alkaline, organic matter 1.3%, 0.08% of total nitrogen, alkali hydrolysis of nitrogen 50ppm, available phosphorus 12ppm, available potassium 180ppm. Broadly speaking, higher elevation, dry climate, large evaporation, rainfall is scarce,
