摘要
试验采用"3414+1"肥效试验方案,建立了回归方程,y=40.93+7.89 N+4.75P+2.38 K+0.05 NP+0.10 NK+0.04PK-0.31 N2-0.31 P2-0.15 K2,导出了潮砂泥田种植油研9号的最佳施肥量为667m2施尿素30.0kg、普钙51.3kg、氯化钾17.3kg,可获产量140.5kg/667m2。同时对有机肥的增产效果进行分析,施用有机肥2500kg/667m2的条件下,每100kg有机肥可增产油菜1.53kg/667m2,增产率为3.69%。
＂3414＋1＂was carried on the fertilizer test,regression equation was established that y=40.93＋7.89N＋4.75P＋ 2.38K＋0.05NP＋0.10NK＋0.04PK-0.31N2-0.31P2-0.15K2,the best fertilization of urea,superphosphate,potassium chloride was 30.0kg,51.3kg,17.3kg/667m2 respectively for rape,which can obtain the yield 140.5kg/667m2.From data analysis,organic matter was 2500kg/667m2,the yield of rapeseeds increased 1.53kg/667m2 with the increase of 100kg organic matter,increased 3.69%.
