| 摘 要： | [目的]为珍珠番石榴科学施肥提供理论依据。[方法]以珍珠番石榴为试验材料,固定磷肥为0.6 kg株/,进行氮钾2因素3水平的肥效试验。[结果]以处理⑧的施肥方案为好,即尿素、过磷酸钙和氯化钾的用量分别为0.8、0.6和0.8 kg株/。通过二元二次方程拟合,氮磷钾肥的最佳施肥方案为0.8∶0.6∶0.8,通过一元二次方程单因素肥料拟合,氮磷钾肥的最佳施肥方案为0.93∶0.60∶0.73。[结论]珍珠番石榴施肥最佳N、P2O5、K2O施肥比例为4∶1∶4。

| Abstract: | [Objective] The study was to provide the theoretical basis for the scientific fertilization of pearl guava.[Method] With pearl guava as tested materials,fixing P fertilizer is 0.6 kg per tree,carrying out 2 factors and 3 levels treatments for fertilizer effect.[Result] Treatment 8 is best,that is 0.8 kg urea +0.6 kg Ca(H2PO4)2 +0.8 kg KCl per tree.The result by using binary quadric equation fitting showed that the best fertilizer formula was using 0.8 kg urea +0.6 kg Ca(H2PO4)2 +0.8 kg KCl per tree.The result by using unary quadratic equation fitting showed that the best fertilizer formula was using 0.93 kg urea +0.60 kg Ca(H2PO4)2 +0.73 kg KCl per tree.[Conclusion] The best fertilizer formula proportion of N,P2O5and K2O was 4∶1∶4. |
