| 摘 要： | 采用正交设计，研究播期、密度和施氮量等栽培因子对皖油29产量的影响。结果表明：（1）栽培因子对产量影响大小顺序为播期〉密度〉施氮量。（2）皖油29高产最佳模式为9月25日播，18万株·hm^-2、施氮量255kg·hm^-2。（3）皖油29应适期早播，以利个体充分生长获得高产；随着密度的增加，一次有效分枝数、单株有效角果数、每角粒数、千粒重呈现逐渐减少趋势；随着氮肥施用量的增加，单株有效角果数随之增加，每角粒数呈先增后减的趋势，千粒重变化不大。

| Abstract: | With the orthogonal design,three factors(planting date,plant density and nitrogen supply) were investigated to research the effects of cultivation factors on yield of rapeseed Wan-you No.29.The result indicated:(1) under this research condition,the size order of the effects of cultivation factors on rapeseed yield was planting date >plant density >nitrogen supply.(2) the best patterns of high yield for Wan-you No.29 were planting on September 25th,180000 plants.hm-2 and 255Kg N.hm-2.(3) Wan-you No.29 should... |
