摘  要:
采用田间小区试验研究了不同专用肥配方及其施用技术对玉米氮磷钾养分吸收、产量及其经济效益的影响。结果表明,施用3号专用肥玉米的产量、氮磷钾养分吸收和经济效益最高,其施肥技术为100kg口肥配合500kg底肥施用;施用5号专用肥玉米的产量、氮磷钾养分吸收和经济效益次之;施用1号专用肥的产量和效益最低。因此,本试验条件下推荐选用3号玉米专用肥并以100kg口肥和500kg底肥配合施用,玉米能获得高产高效。

摘  要:
Field experiment was conducted to investigate effects of different maize specific fertilizers on nutrient uptake, yield and profit. The results indicated that among nine fertilizer treatment, the treatment No.6(No.3 fertilizer, 26-10-12) achieved highest nitrogen(N), phosphorous(P) and potassium(K) absorption, highest yield and highest profit, with 100 kg/ha applied as seed fertilizer and 500 kg/ha as bottom fertilizer. The nutrient uptake, yield and profit of treatment No.9(No.5 fertilizer, 30-10-12) ranked second, and treatment No.2(No.1 fertilizer, 21-7-12) obtained lowest yield and profit. Therefore, under condition of this experiment, treatment No.6(No.3 fertilizer, 26-10-12) with 100 kg/ha applied as seed fertilizer and 500 kg/ha as bottom fertilizer was recommended to use in high yield and high efficient maize production.
