| 摘 要： | 运用最优回归设计，对大穗型杂交稻京福1优527进行密度和氮、磷、钾肥施用量4项栽培措施与产量、净收入之间的关系进行试验研究。结果表明，4项措施对产量、净收入都有影响，经微机模拟筛选出高产高效的技术措施是每公顷插22万～32万丛，施肥量折算为N134．9～169．7kg、P2O542．0～71．3kg、K2O75．5～133．5kg。

| Abstract: | Optimization of N,P and K fertilization for high density cultivation of the large-spike type hybrid rice, Jinfu 1 You 527,was conducted.Regression analyses between the cultivation conditions and rice yield and net income from the harvest were performed.The results showed that all factors examined had a significant effect on yield and net income.Using a computerized imitative screening method,the optimized number of rice bushes per hectare was 220 000 to 320 000,and the fertilization rates for N was 134.9-16... |
