湖北省国营三湖农场,利用装有设备的“运—5”型飞机,直接进行水稻播种和喷药等田间作业,大幅度地提高劳动生产率。1979年全场飞机作业面积共有8,708亩次,其中直播稻种2,403亩,喷洒化学除草剂3,505亩,喷施杀虫农药2,800亩,取得较好的效果。 飞机直播水稻时,飞行高度25—28米,播种幅宽22米,飞机速度每秒44.5米。每一架次机内金属种子桶容纳催芽稻种1,600斤,可播种80亩,只需五分钟的时间。播后一个月,最高苗数达47万。
Hubei State-run Sanhu Farm uses the “Yun-5” -type aircraft equipped with equipment to carry out field operations such as sowing and spraying rice directly and greatly increase labor productivity. In 1979, there were 8,708 mu acreage of aircraft in operation, including 2,403 mu of direct-seeded rice, 3,505 mu of chemical herbicide and 2,800 mu of pesticide pesticide sprayed, achieving good results. Plane broadcast rice, the flight altitude of 25-28 meters, sowing width of 22 meters, the aircraft speed of 44.5 meters per second. Each shelf metal seed bucket to accommodate the germination of rice varieties 1,600 pounds, 80 acres can sow, just five minutes. One month after sowing, the highest seedling number reached 470,000.
