摘　　要：基于吉林省中部地区玉米“3414”田间肥效试验,研究不同氮磷钾肥料配比对白浆土养分性质的影响,最终提出最佳的施肥策略。结果表明,适量供应磷钾肥基础上,增施氮肥使土壤有机质趋于矿化。推荐施肥量(N-P_(2)O_(5)-K_(2)O 220-80-90 kg/hm^(2))更有利于土壤碱解氮的耗竭。与不施肥相比,施肥均有利于速效钾含量的提升。在磷钾适量供应情况下,不施或低量施氮均有利于土壤速效钾的积累,而在氮磷适量供应条件下,低量或过量施钾均有利于有效磷的积累。Based on the"3414"field experiment of maize in central Jilin Province,the effects of different nitrogen,phosphorus and potassium fertilizer ratios on nutrient properties of white clay soil were studied,and the optimal fertilization strategies were proposed.The results showed that soil organic matter tended to be mineralized on the basis of proper supply of p and K fertilizer.The recommended fertilizer application rate(N-P_(2)O_(5)-K_(2)O 220-80-90 kg/hm^(2))was more conducive to soil alkali-hydrolyzed N depletion.Compared with no fertilization,fertilization was beneficial to increase the content of available potassium.Under the condition of proper supply of P and K,no or low amount of N application was beneficial to the accumulation of available K,while under the condition of proper supply of N and P,low or excessive amount of K application was beneficial to the accumulation of available P.
