摘要
为了探明柳江县香葱的最佳施肥方案,采用正交试验法开展香葱氮磷钾肥料配比的优化试验。结果表明,处理6(N2P3K1)的株高、葱白长度、根长和单丛重均达最高,每667 m2产值达9 577.26元,比对照处理提高17.71%效益。因此,N2P3K1为最佳氮磷钾施肥方案,N∶P2O5∶K2O比值为1∶0.42∶0.84。氮磷钾3个因素对香葱产量影响的强弱顺序为氮>钾>磷。
With orthogonal experiment method, the fertilization level of different N, P and K on chive was optimized for ascertaining the best application fertilizer scheme in Liujiang county. Results showed that the treatment of No.6 （ N2P3K1 ） was the best combination with the highest plant height, length of white stalk, root length and fresh weight per cluster. The output value per 667 m^2 was 9 577.26 Yuan, and 17.71 percent higher than that of the control. The optimum fertilization level of N, P and K was N2P3Kt, and the application ratio of N ： P2O5 ： K2O was 1 ： 0.42 ： 0.84. The effect order of N, P and K fertilization on chive yield was N〉K〉P.
