| 摘 要： | 在田间试验条件下研究了施肥对“秦油二号”杂交油菜氮、磷、钾营养及其产量的影响,结果表明:单施氮肥,增加植株氮、磷、钾吸收强度和植株含氮浓度,但对植株磷、钾浓度无明显影响。氮磷配施既能显著提高植株氮、磷、钾吸收强度,也能增加植株氮、磷、钾浓度。在施用氮、磷肥料基础上配施氯化钾肥,降低了植株氮、磷吸收强度和氮浓度。施肥使油菜氮,磷营养吸收高峰推迟。吸氮高峰期在油菜苔期,吸磷高峰期在油菜花角期。在本试验条件下,氮肥与磷肥配合施用油菜产量和经济效益最高,比单施氮肥增产23.2％,比氮磷钾配施增产11.4％,每亩增收三十无以上。

| Abstract: | A field experiment was conducted for examining the effect of different fertilizers on the yield and N. P. K absorption chacteristics of the hybrid rape. The result showed that the potash chloride application to soil with available K of 141 ppm would decrease the rapeseed yield and depress the content and the absorption intensity of N and P in the rape plant. It is significant in role for increasing N. P. K absorption,seed yield and economic benefit, when nitrogen was applied supplemented with phosphorous. The highest absorption intensity of N was found from budding to flowering stage ,and that of P from flowering to mature stage. The N. P absotion ratio equaled approximatively to 1:0. 2. |
