摘  要:
运用裂区试验研究了密度和施氮量对油研九号产量的影响。结果表明 ,密度、施氮量以及密度和施氮量的交互作用对产量的影响均达到显著或极显著水平。产量达 30 0 0kg/hm2 的栽培措施是每hm2 施纯氮 2 70kg、密度 18万株。产量性状间的相关与通径分析表明 :一次分枝数、二次分枝数、群体有效角果数、主花序长通过群体干物重对产量产生了较大影响 ,并与产量间均呈显著的相关性 ,高产栽培的主攻方向是提高整个群体的干物质重量

摘  要:
Split-plot experiment was conducted to study the effect of density and amount of fertilizer application on Youyan 9. Result showed that the effect difference of planting density, amount of fertilizer application,and its interaction on yield reached significance level or very significance level. With yield of above 3000kg/ha, the most suitable density of Youyan 9, the best (amount) of fertilizer (pure N) was 270kg/ha in this experiment.Result of correlation and path analysis are as follow: first branch numbers, secondary branch numbers, effective silique numbers, main inflorscence length (affected) largliy on yield through dry matter weight,and showed significant correlation between these characters and yield.The attack goal of high yield cultivation is to increase dry matter weight of population.
