根据江苏农学院凌启鸿教授等所创立的水稻叶龄模式理论,能够按照叶龄进程,模式化地揭示水稻一生的生育规律,数量化地确立水稻高产的主要生育指标,并得以规范化地制定出水稻不同类型和品种的栽培促控技术措施。 1985年以来,京山县农业局运用水稻叶龄模式技术对杂交中稻汕优63组合高产栽培技术进行了大量的试验示范和经验总结,并将该项技术在全县范围广泛运用,为汕优63在全县大面积推广,大幅度增产起到了较大的作用。总结这几年工作,我们运用水稻 According to the theory of the leaf age model of rice established by Professor Ling Qixong of Jiangsu Agricultural College, the law of birth of rice can be revealed according to the process of leaf age, and the main fertility index of rice is quantitatively established, and the standard of rice Cultivation and Control Techniques of Different Types and Varieties. Since 1985, Jingshan County Bureau of Agriculture has made a large number of experimental demonstration and experience with high-yielding cultivation techniques of hybrid middle-season hybrid rice Shanyou 63 by using the technology of rice leaf age model, and has extensively applied this technology in Shanyou 63 Large-scale promotion in the county, a substantial increase in production played a greater role. Summarize these years of work, we use rice
