摘要
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。
The experiment on model culture of the middle-season hybrid rice 'Shan-you 63' is an important project of Sci-technigue Committee of Qi-andongnan Profecture of Guizhou Province during 1985-1989. With system scientific principle, model of leaf age, computer optimum-seeking technoque, plot experiment and representative test were carried out.On the base of exper-iments above cultural techniques and quantitative and qualitative indexes of growing and developing were gained.Three-year study (1987-1989) indicated, drain yield increased significantly, representative area 77467mu, net-gain 65, 536,500kg, mean yield increased 17.2%. This technique was welcome for farmers.
