地处陇东黄土高原的庆阳地区农科所,海拔高度1421.9米,年平均降水量551毫米,等于或大于5毫米年降水日31.8天,一月平均气温-5.7℃,绝对最低气温-22.4℃。土壤多属黑垆土,微碱性。干旱多灾是本地区农业气候特点。冬小麦是庆阳地区的主要粮食作物,播种面积每年约300万亩,占全区粮田总面积的60%以上。冬小麦生产情况如何,对全年粮食形势和人民生活具有决定性的作用。生产,繁育冬小麦良种是我所主要科研任务之一。建所初,由于土地瘠薄,耕作粗放,品种严重老化、混杂,小麦产量很低,亩产仅百斤左右。六十年代初,通过引用、繁育良种,改进耕作栽培
Located in Longdong loess plateau Qingyang Prefecture Agricultural Institute, altitude 1421.9 meters, the annual average precipitation 551 mm, equal to or greater than 5 mm annual precipitation 31.8 days, January average temperature of -5.7 ℃, the absolute minimum temperature of -22.4 ℃. Soil mostly black soil, slightly alkaline. Droughts and drought is the region’s agricultural climate characteristics. Winter wheat is the main food crop in Qingyang. The sown area is about 3 million mu per year, accounting for more than 60% of the total grain crop area in the region. How the winter wheat production is going to have a decisive effect on the food situation and people’s livelihood throughout the year. Production and breeding of winter wheat is one of my major research tasks. Since the beginning of the establishment, due to the infertile land and extensive cultivation, the varieties are seriously aged and mixed with low yields of wheat and only about one hundred pounds per mu. In the early 1960s, cultivating cultivated land was improved by quoting and breeding fine varieties
