“育秧移栽”能经济利用土地,增加复种指数,便于集中管理,节约用水、用肥,是我国水稻生产上精耕细作的一项重要措施。早在一千四百年前《齐民要术》一书的水稻篇中,就有“既生七八寸,拔而栽之”的记载。随着农业生产的发展,育秧技术也不断改进。近几年来,本省更由于改制的深入展开,水田新三熟制的出现,春花田早稻的秧龄问题就列入了生产实践上的新课题。绍兴县东湖农场副场长胡香泉同志在1959年根据他前四年试种春花田早稻的经验,冲破了以往早稻秧龄不能超过30天的旧框子,提出了“长秧龄”的新概念,从而引起了秧龄长短问题的普遍争论。明确这一问题,对提高农业科学理论和指导生产实践都有重要意义。 “Transplantation of seedlings” can economically utilize land, increase the multiple cropping index, facilitate centralized management, save water and use fertilizer, which is an important measure of intensive cultivation in China’s rice production. As early as 1400 years ago, “Qi Min Yao Shu” in a book of rice, there is “born seven-inch, pull and planted” record. With the development of agricultural production, seedling technology has also been continuously improved. In recent years, due to the deepening of restructuring in our province and the emergence of the third paddy crop in paddy fields, the issue of the young seedling age of Chunhuatian has been included in the new issue of production practice. In 1959, Comrade Hu Xiangquan, deputy director of East Lake Farm in Shaoxing County, broke through the old frame of early rice that can not exceed 30 days according to his first four years of experimenting with early spring rice and put forward a new concept of “long seedling age” The general debate about the issue of seedling age. To clarify this issue is of great significance to improving agricultural scientific theory and guiding production practice.
