摘要： 运用最优设计，对特优73进行移栽叶龄、密度和施N量3项栽培措施研究。建立产量、净收入与3项栽培措施的回归模型。分析了栽培措施对产量、净收入的影响，结果表明，3项措施对产量、净收入都有影响。并经微机模拟筛选出高产高效的技术措施是：5~6叶移栽，每公顷插17.55~28.28万丛，施纯N量140~188kg。

Abstract: A comprehensive culture techniques for the Hybrid Rice-Teyou 73 was studied by the method of optimization design. Three influential elements for the culture techniques were leaf age in transplanting（x1），planting density（x2），quantities of nitrogen（x3）.The regression models of three elements with yield，net revenue were established. The results showed that three elements influenced the yield and net revenue. After simulated screening and optimal selection by computer，the comprehensive culture techniques of high yield and efficiency were 5-6 leaves for transplanting，as 175500-282800 hills per hm2，and 140-188kg N per hm2.
