一、试验区概述与试验结果: 甘南州地处青藏高原东部边缘,属于中纬度高海拔的高寒阴湿草原牧区。州内部分海拔2500米左右的河谷地带,光照条件好,昼夜温差大,有机质丰富,灌溉方便,宜于农作,具有高原春小麦高产的优势生态条件。完尕滩川道地区,地处大夏河沿岸,属上述生态区,春小麦占总播种面积的65％,是夏河县作物高产区。完尕滩地区虽然光照条件较差,但4至8月份气候适宜,小麦抽穗至成熟期的日数长达63天,除比香日德少5天外,均多于其它高原小麦产区(见表一)。但自七十年代以来,粮食亩产一直徘徊在中产水平。
First, the experimental area overview and test results: Gannan Prefecture is located on the eastern edge of the Qinghai-Tibet Plateau, belonging to mid-latitude high altitude wet grassland pastoral areas. The state part of the river valley about 2,500 meters above sea level, good light conditions, large temperature difference between day and night, rich organic matter, irrigation convenience, suitable for farming, with high spring wheat yield superior ecological conditions. End of Gansu Tanchuan area, is located along the Daxia River, is the above ecological zone, spring wheat accounts for 65% of the total sown area, is the high-yielding crops in Xiahe County. Although the light conditions in WanGanTan were poor, the climate was suitable from April to August, and the number of days from heading to maturity was 63 days, except for 5 days less than XiangJiDu than other highland wheat producing areas (see table one). However, grain output has been hovering at the middle level since the 1970s.
