摘要
采用五元二次正交回归旋转组合设计，通过田间试验，分析了胡麻籽粒产量、籽粒含油率、油脂产量及其亚麻酸、亚油酸含量、经济纯收入等目标性状与播量、播期、有机肥施用量、施氮量、施磷量等栽培因素之间的关系，建立了数学模型。通过计算机寻优，得出了一套高产优质高效栽培优化方案和三套高产栽培优化方案。在试验地的气候和生产条件下，胡麻适期早播是关键，注重施用有机肥和磷肥，合理施用氮肥可以达到高产优质高效的目的。
A field experiment in five factors quadratic orthoganol regression rotary composite design was conducted to study the relationships between the target characters such as linseed yield,oil bearing rate, oil production, linolenic acid and linoleic contents,pure profitsand cultivation elements such as seeding rate and time,amount of organic matter, nitrogenand phosphorus applied. As a result, a optimum cultivation program for high yield, goodquality and high efficiency and three high yield cultivation programs were obtained.Theseresults showed that early seeding was a key point, the amount of organic matter and P fertilizer should be emphasized,and resonable application N fertilizer could attain the goal with high yield,good quality and high efficiency.
