杂交中稻“汕优63”模式栽培,是黔东南州科委“七五”期间攻关项目。它利用系统工程的原理,以叶龄模式的理论为指导,通过一系列小区试验,用电子计算机模拟选优,再到生产上示范,获得反馈信息,形成定性、定量的综合配套栽培技术体系和相应的生长发育指标体系。经1987～1989年三年实践结果,增产效果显著。三年来,示范推广面积达77467亩,净增稻谷655.365万公斤,平均增产17.2％,深受广大农民群众的欢迎。
Hybrid rice “Shanyou 63” model cultivation, Qiandongnan Prefecture Science and Technology Commission during the “Seventh Five-Year” key project. It uses the principle of system engineering, guided by the theory of leaf-age model, through a series of cell experiments, using computer simulation to optimize, and then to the production of demonstration, access to feedback, the formation of qualitative and quantitative comprehensive supporting cultivation technology system and Corresponding growth and development index system. After 1987 to 1989 three years of practical results, a significant increase in yield. Over the past three years, the demonstration area has been expanded to 77,467 mu, with a net increase of 6,535,650 kilograms of rice and an average increase of 17.2%. It is greatly welcomed by the peasant masses.
