直播与插秧是水稻栽培上两种不同的栽培方法。我国的直播栽培一般多在气侯寒冷,稻作生长节季短,田多劳动力少的地区采用,如黑龙江、吉林、辽宁、河北、内蒙、宁夏及新疆等省(区)。近年来,国营农场和军垦农场水稻直播发展较快,并开始采用飞机撒播。随着农业生产的发展,在大搞农田基本建设的基础上,不断改进耕作技术,直播产量有了显著的提高,高产的也有亩产超千斤。我省湛江垦区的国营湖光、晨光等农场多年坚持搞水稻水直播,历年单产和总产均比插秧的高。湖光农场1979年水稻直播面积6600亩,平均亩单产634斤。
Live and transplanting rice cultivation is two different cultivation methods. In China, the direct seeding cultivation is mostly applied in the areas where the climate is cold and the rice growing season is short and the fields are less labor-intensive, such as Heilongjiang, Jilin, Liaoning, Hebei, Inner Mongolia, Ningxia and Xinjiang provinces (districts). In recent years, state-owned farms and military reclamation farms live faster development of rice, and began to use aircraft broadcast. With the development of agricultural production, on the basis of vigorously pursuing farmland infrastructures, continuous improvement of cultivation techniques has resulted in a significant increase in the live broadcast production, while the high yield has also exceeded the output per mu. Zhanjiang Reclamation of our state-owned lakes, dawn and other farms insist on engaging in rice water for many years, over the years yield and total output were higher than the transplanting. Lake farm in 1979, 6600 acres of direct broadcast area of rice, the average yield of 634 kg mu.
