摘  要:
试验采用"3414+1"肥效试验方案,建立的回归方程为y=40.93+7.89x1+4.75x2+2.38x3+0.05x1x2+0.10x1x3+0.04x2x3-0.31x21-0.31x22-0.15x23,从而导出了潮沙泥田种植油研9号的最佳施肥量为667 m2施尿素30.0 kg、普钙51.3 kg、氯化钾17.3 kg,可获产量140.5 kg/667m2。在667 m2施用有机肥2 500 kg的条件下,每100 kg有机肥油菜可增产1.53 kg/667m2,增产率为3.69%,增产效果显著。

摘  要:
The regression equation y=40.93+7.89x1+4.75x2+2.38x3+0.05x1x2+0.10x1x3+0.04x2x3-0.31x21-0.31x22-0.15x23 was established for raising yield of Youyan 9,a rape variety by using the "3414+1"design.The results showed that the optimum application amount of N,P and K fertilizer for 140.5 kg/667m2 was urea 30.0 kg/667m2,calcium superphosphate 51.3 kg/667m2 and potassium chloride 17.3 kg/667m2,and every 100 kg of organic manure can increase by 1.53 kg/667m2 of rapeseed yield under applying 2 500 kg/667m2 of organic manure and its increment rate is 3.69%.
