| 摘 要： | 采用“3414”肥料效应田间试验方案,对谷子氮、磷、钾肥效应进行研究,同时对谷子产量进行肥效模型拟合,得出氮、磷、钾肥的最优推荐施肥量。结果表明：氮、磷、钾肥配合施用可以显著增加谷子的穗长、穗粗、单穗重、穗粒重和产量。氮、磷、钾肥对谷子经济性状的影响为氮>磷>钾。通过三元二次肥效模拟方程可以得出,豫谷23的最佳施肥量分别为N 165.33kg/hm 2、P2O5 115.93kg/hm 2、K2O 32.48kg/hm 2。通过一元二次肥效模拟方程可以得出,豫谷23的最佳施肥量分别为N 162.66kg/hm 2、P2O5 109.30kg/hm 2、K2O 32.68kg/hm 2。因此,豫谷23施肥时,应以氮、磷肥为主,兼施钾肥。

| Abstract: | The “3414” fertilizer experiment for high fertilizer efficiency was designed to explore N, P and K fertilizer effects in foxtail millet production and to simulate the optimum fertilization parameter by the established models for scientific fertilization. The results showed that N, P and K fertilizer application can significantly increase panicle length, ear diameter, single panicle weight, grain weight per panicle and yield of foxtail millet. The effects of N, P and K fertilizer on economic traits were in order: N>P>K. According to the ternary quadratic fertilizer efficiency equation, the most suitable amount of fertilizer in Yugu 23 were N 165.33kg/hm 2, P2O5 115.93kg/hm 2, K2O 32.48kg/hm 2, respectively. According to the one-variable quadratic fertilizer efficiency equation, the recommended optimum amount of fertilizer in Yugu 23 were N 162.66kg/hm 2, P2O5 109.30kg/hm 2, K2O 32.68kg/hm 2, respectively. The application of N, P, K fertilizer of Yugu 23 should be emphasized with increasing amounts of N, P and supplemented with K. |
