水稻叶龄模式是一种新的水稻高产栽培理论与技术体系。它按叶龄进程模式化地揭示了水稻一生的生育规律,数量化地确定了水稻高产的主要生育指标,并使不同类型,品种的水稻栽培技术趋向规范化。这种水稻栽培理论与技术体系,理论根据充分,诊断指标确切,栽培措施配套,应用效果显著。1981至1985年,已相继于上海、安徽、湖南、山东、福建、辽宁、广西、新疆等21个省、市、自治区推广,累计应用面积5900万亩,平均增产12%,农本降低5—11%,获得的总经济效益达13亿3千1百万元。该成果于 Rice leaf age model is a new rice high yield cultivation theory and technology system. According to the process of leaf age, it reveals the law of birth of rice in a modeled manner, quantitatively determines the main fertility index of high-yielding rice and standardizes the cultivation techniques of rice of different types and varieties. This rice cultivation theory and technology system, based on the full theory, the exact diagnostic indicators, supporting the cultivation measures, the application of significant results. From 1981 to 1985, it was successively promoted in 21 provinces, cities and autonomous regions in Shanghai, Anhui, Hunan, Shandong, Fujian, Liaoning, Guangxi and Xinjiang. The accumulated area of ​​59 million mu was applied, with an average increase of 12% 11%, and the total economic benefits obtained reached 1.3131 billion yuan. The result at
