我师地处西北边陲,位于北纬45°～47°的塔、额、裕、托四县境内,三面环山,西南开口与苏联接壤。年平均气温5.5℃,年平均降水量275毫米,年蒸发量1670毫米,日照时数为2840小时,无霜期110～140天。全师现有土地总面积656.5万亩,其中耕地125万亩,耕地海拔高程在460～1200米之间,坡度17～50％。土壤有机质1～3％,碱解氮20ppm以上,速效磷10PPM以上。 我师的土地辽阔,有大小河流31条,年总径流量3.2亿m~3,但因山低融雪快,时间短,洪水集中在五月份以前,由于水库容量只有4000万立方,所以大部分水都跑掉了,不能利用。从五月中旬以后水开始紧张,六、
My teacher is located in the northwestern border, located in the north latitude 45 ° ~ 47 ° towers, forehead, Yu, Tuo four counties, surrounded by mountains, the southwest opening and the Soviet border. The annual average temperature of 5.5 ℃, the average annual rainfall of 275 mm, the annual evaporation of 1670 mm, sunshine hours of 2840 hours, frost-free period of 110 to 140 days. The division has a total area of 656.5 hectares of land, of which 125 mu of arable land, arable land elevation of 460 to 1,200 meters, the slope of 17 to 50%. Soil organic matter 1 to 3%, more than 20ppm of alkaline hydrolysis of nitrogen, available phosphorus 10PPM above. My teacher’s land is vast, there are 31 rivers and streams, with a total annual runoff of 320 million m ~ 3, but due to low melting snow mountain, a short time, the flood concentrated in May before, because the reservoir capacity of only 40 million cubic meters, so most Water ran away, can not be used. Water has started to tense since mid-May,
