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。
By using the optimal design, three cultivation measures of transplanted leaf age, density and N application rate were studied on high-quality early rice Jinyouming10. Establish a regression model of production, net income and three cultivation measures. The effects of cultivation measures on yield and net income were analyzed. The results showed that all three measures had an impact on output and net income. The computer simulation of high-yielding and efficient technical measures are: 4.69 ~ 4.81 leaf transplanting, inserted per hectare 2 4.3 8 ~ 258700 clumps, applying pure N 15 9.8 ~ 168.9kg.
