一、发挥排灌机械工作效能的意义1958年全国农田排灌机械在发挥机器效能方面有了很大进步,一马力的平均受益面积从1957年的40来亩增加到50亩左右,提高了25%。浙江和江苏省已分别达到89亩和70亩,都比1957年提高了40%左右。有些地区先进的抽水机站平均每马力受益面积还达到100、200亩,甚至超过300亩,而且都能做到及时灌溉排涝,保证了农业丰收。在旱涝保丰收的前提下,充分发挥排灌机械的工作效能,提高单位马力受益面积有那些重要意义呢?
First, the significance of the performance of irrigation and drainage machinery 1958 Farmland irrigation and drainage machinery in the country have made great progress in machine performance, the average benefit from a horsepower in 1957 from 40 acres to about 50 acres, an increase of 25%. Zhejiang and Jiangsu Provinces have achieved 89 mu and 70 mu respectively, which are all about 40% more than in 1957. In some areas, the average pumping area per horsepower benefited from an area of 100,200 mu or even more than 300 mu, and timely irrigation and drainage can ensure timely agricultural harvest. Under the premise of drought and flood protection harvesting, it is of great significance to give full play to the work efficiency of irrigation and drainage machinery and improve the horsepower benefit per unit area.
