摘　　要：运用最优设计 ,对优质早稻金优明 10 0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。经计算机模拟筛选出高产高效的技术措施是 :4.69～ 4.81叶移栽 ,每公顷插 2 4.3 8～ 2 5 .87万丛 ,施纯N量 15 9.8～ 168.9kg。Comprehensive culture techniques for Super hybrid rice-Jinyouming100 were studied by means of optimum design. Three influential elements for the culture techniques were leaf age in transplanting(x 1),planting density(x 2),quantity of nitrogen(x 3).The regression models of the three elements with yield and net revenue were established. The results showed that the three elements affected the yield and net revenue. After simulated screening and optimal selection by computer,the comprehensive culture techniques for high yield and efficiency were 4.69～4.81 leaves for transplanting,243800～258700 hills per hm 2,and 159.8 ～168.9 kg N per hm 2.
