直播与移栽是稻作生产中两种不同的栽培方法,各有其适应的条件和栽培特点。国外如印度,意大利、葡萄牙、澳大利亚、埃及等许多产稻国家,都广泛采用直播栽培,以利实现稻作机械化和大幅度提高劳动生产率。我国五十年代初期也开展了水稻直播的研究。近几年,水稻直播面积正在扩大,1979年我国水稻水直播面积达180万亩。并在千亩的较大面积上,获得一季亩产800斤以上的好收成。
Direct seeding and transplanting are two different cultivation methods in rice production, each of which has its own adaptable conditions and cultivation characteristics. In many foreign countries such as India, Italy, Portugal, Australia and Egypt, direct-seeded cultivation is widely adopted to facilitate the mechanization of rice cultivation and substantially increase labor productivity. China’s early 50s also launched a study of direct seeding rice. In recent years, the direct broadcast area of rice is expanding. In 1979, the area of rice water direct broadcasting in China reached 180 million mu. And in a larger area of acres, access to a quarter of more than 800 pounds per mu yield.
