| 摘 要： | 为实现花生科学施肥,采用田间试验研究了氮磷钾配施对花生产量、养分吸收、干物质积累及肥料利用率的影响。结果表明:氮磷钾配施显著增产46.82%,较农户施肥增产7.53%;施氮、磷、钾肥分别增产27.80%、13.56%、21.12%。氮磷钾配施养分积累量较农户施肥分别提高13.30%、36.48%、40.75%,氮、磷、钾肥当季利用率分别为33.39%、15.17%、39.02%。氮磷钾配施(N-90、P_2O_5-120、K_2O-150 kg/hm~2)促进了花生对氮、磷、钾养分的吸收利用,提高了花生产量,可作为潮土区花生高产施肥配方。

Combined Application of N, P and K Affecting Yield and Nutrient Absorption of Peanut in Fluvo-aquic Soil |
| |
| Abstract: | To achieve scientific fertilization for peanut. Field experiments were conducted to study the influence of combined application of N, P and K on peanut yield, nutrient absorption, accumulation of dry matter, and the fertilizer utilization ratio. The results showed that treatment with NPK fertilization and farmers fertilizer, the yield increased by 46.82% and 7.53% respectively; the yield increased rate of N,P and K fertilizers application was 27.80%, 13.56% and 21.12%, respectively. With nutrient accumulation more farmers NPK fertilization increased by 13.30%, 36.48% and 40.75%, respectively, the material utilization ratio of N, P and K fertilizers were 33.39%, 15.17% and 39.02%, respectively. The combined application of N, P and K (N-90, P2O5-120, K2O-150 kg/hm2) promoted the peanuts for N, P and K nutrient absorption and utilization, and increased the yield of peanut, therefore, it can be used as formula fertilizer of achieving high yield of fluvo-aquic soil in peanut. |
