摘要
本研究以系统工程的原理和水稻叶龄模式的理论为指导,在对“汕优63”生育特点进行系统研究的基础上,提出了一套以“汕优63”为代表,以叶龄指标为中心的杂稻丰产生长发育指标体系、生产目标体系。明确了主要技术措施的适用条件、相互影响及其对水稻植株器官的效应。1987年至1989年模式栽培技术推广面累计近8万亩,净增稻谷655.4万公斤。
By the principle of systematic engineering and model theory of leaf age, the growth feature of hybrid rice Shanyou No. 63 was studied systematically. The system of both growth index and production aim of hybrid rice was provided. The suitable condition of main cultivation methods, the influence of which each other and its effect to rice plant was indicated.
