我县地处雅鲁藏布江中下游,位于沿江两岸的九个公社,无霜期150天左右,南北山区的14个公社(其中有个纯牧业社),无霜期120天左右。全县总耕地面积约24767克(一克相当于一亩)。在过去,粮食作物以青稞为主,历史上最高产量为七百四十余万斤,单产三百三十二斤。无产阶级文化大革命以来,特别是1970年北方地区农业会议以后,全县掀起了“农业学大寨”运动高潮。从1970年秋开始,连续五年试种和推广了优良品种肥麦冬小麦,并连年获得了增产,1971年372克地的冬小麦平均单产440斤,1972年3196克地的冬小麦平均单产477斤,1973年9000克地的冬小麦,平均单产585斤。但是,近两年来由于地下害虫(特别是地老虎)的为害,对我县的农业生产造成了严重威胁。1974年,全县13000多克的冬小麦,在返青、拔节时遭受虫灾,面积达9600多克,其中受害严重的
My county is located in the middle and lower reaches of the Brahmaputra, located in nine communes along the banks of the river, frost-free period of about 150 days, 14 communes in the northern and southern mountains (including a pure animal husbandry clubs), frost-free period of 120 days. The county total area of about 24767 grams of arable land (one gram is equivalent to one acre). In the past, the main crops were barley, the highest output in history was more than 7,400 kg and a yield of 333 kg. Since the great proletarian cultural revolution, especially after the agricultural conference in the north of China in 1970, the climax of the “agricultural learning Dazhai” campaign was launched throughout the county. From the autumn of 1970, five years of continuous trial and promotion of fine varieties of winter wheat and winter wheat yield increased in successive years. The average yield of winter wheat in 372 grams in 1971 was 440 kg. In 1972, the average yield of winter wheat in 3196 grams was 477 kg. In 1973, Annual 9000 grams of winter wheat, with an average yield of 585 pounds. However, the damage caused by underground pests (especially land tigers) in recent two years has posed a serious threat to the agricultural production in our county. In 1974, over 13,000 grams of winter wheat in the county suffered pest plagues when returning to green and jointing, covering an area of more than 9,600 grams, of which severely harmed
