一、超级稻栽培的关键技术针对超级稻高产栽培的特点,生产中需要解决的关键技术问题是:氮肥的科学施用,群体的合理控制(定苗),病虫的有效防治。其中,氮肥施用是超级稻生长发育调控的核心,掌握了氮肥施用的科学方法,也就掌握了超级稻栽培的关键技术——测苗定量施肥。
A key technology for super rice cultivation Aiming at the characteristics of super high-yielding cultivation of rice, the key technical problems to be solved in production are: scientific application of nitrogenous fertilizer, reasonable control of groups (Dingmiao) and effective prevention and control of pests and diseases. Among them, the application of nitrogen fertilizer is the core of super rice growth and development control, mastered the scientific method of nitrogen application, also mastered the key technology of super rice cultivation - seedling quantitative fertilization.
