“水稻生育进程叶龄模式”(本文简称“叶龄模式”——下同)是江苏农学院在多年研究和生产实践基础上,进行归纳、配套、补充、发展而形成的。在上海市郊区国营农场单季稻栽培上,已经应用多年,被公认为是适合农场生产实际的水稻栽培技术体系,并为农场广大科技人员所掌握。自1983年以来,我们在带土小苗栽培中,根据这一体系的主要内容,初步摸索出带土小苗“叶龄模式”栽培技术。现分述如下: The “Rice Age Mode” (hereinafter referred to as the “Leaf Age Model” - the same below) is formed by Jiangsu Agricultural College on the basis of years of research and production practices, induction, support, supplement and development. It has been used for many years in the cultivation of single-season rice on the state-owned farms in the suburbs of Shanghai. It has been recognized as a practical system of rice cultivation techniques suitable for farms and has been mastered by the vast majority of farm scientists and technicians. Since 1983, we planted soil seedling cultivation, according to the main contents of this system, initially explored with soil seedling “leaf age mode” cultivation techniques. Now as follows:
