摘要
为了提出一套油研６号高产配套栽培技术，在不同海拔地区设置不同栽培因素的正交试验结果表明：播期和密度是主导因素；不同栽培因素通过对产量构成因素的作用而对产量发生影响；各栽培因素与产量及亩有效角果数呈一元二次回归ｙ＝ａ＋ｂｘ＋ｃｘ￣２，各栽培因素与角粒数、千粒重呈直线回归ｙ＝ａ＋ｂｘ；油研６号适宜播期为９月１５～２５日，密度为７０００～９０００株／亩，尿素追肥用量为１５～２５ｋｇ／亩，钙镁磷肥为２５～５０ｋｇ／亩，硼砂为０．５～０．９ｋｇ／亩，亩产量达１５０ｋｇ以上。
An orthogonal experiment with different cultivated factors was conducted at different elevation sites toput forward a set of cultivated technique for higher yield of Youyan 6.The results indicated that the sowingtime and density are dominant factors for yield.the different cultivated factors influence yield by affectingyield components,Every factor shows mono-quadratic regression equation(y=a+bx +cx2)with yield andeffective pods and shows linear regression(y=a+bx) with grain number per pod and thousand grain weigh-t.A set of cultivated technological measure for yielding over l50 kg/mu includes adopting optimum sowingtime on l5～25th Sept,and density between 7000～9000 plants/mu,and applying l5～25 kg/mu of urea foradditional fertilizer,25～50/mu of calcium magnesium phosphate and0.5～0.9 kg/mu of borax.
