喷灌技术的发展,对顺义县稂食和农业的发展起了积极作用。他们认为:喷灌与井渠灌溉相比,一段可节水50%以上,增加播种面积20%以上,节电25%以上,节省劳力50%以上,又便于机械作业。一、因势利导发展粮田喷灌顺义县位于北京市东北部,大部分耕地地势平坦,土壤肥沃,总耕地面积86万多亩,其中粮田70万亩。主要农作物为小麦、玉米,一年两作。近千年来,随着乡镇企业的崛起,多种经营的开展,使农村劳动力大量转移,土地适度规模经营与各种工程技术措施结合,使农村经济发生了很大变化。1988年粮食总产达到4.5亿多公斤。目前他们正在为粮食生产登上新台阶而努力。顺义县水资源丰富,境内有大小河流15条,其中潮白河横贯全境,夏季可供泻洪排涝,冬季可拦河蓄水;还有水库等蓄水工程和灌区,建立了固定的机电
Sprinkler irrigation technology development, Shunyi County, food and agriculture development has played an active role. They think: Compared with well irrigation, sprinkler irrigation can save more than 50% of the water, increase the sown area by more than 20%, save electricity by more than 25% and save labor by more than 50%, which is convenient for mechanical operation. First, make the most of the development of grain irrigated Shunyi County is located in the northeast of Beijing, most of the cultivated land is flat and fertile soil, the total cultivated area of more than 860000 acres, of which 700000 acres of grain. The main crops are wheat and corn, two crops a year. In the past millennium, with the rise of township and village enterprises and the diversification of industries, a large number of rural labors have been diverted. Due to the moderate scale operation of land and various engineering and technical measures, the rural economy has undergone great changes. The total grain output in 1988 reached more than 450 million kilograms. Currently they are working for a new level of food production. Shunyi County, rich in water resources, the territory of the size of 15 rivers, of which the Chaobai River runs through the whole territory in summer for diarrhea flood drainage, river water storage in winter; there are reservoirs and other irrigation projects and irrigation areas, the establishment of a fixed electromechanical
