摘要
[目的]研究配方施肥对小麦的增产效应。[方法]试验设配方施肥区和常规施肥区,从产量、肥料利用率和效益3个方面进行分析。[结果]配方施肥区的小麦N、P、K利用率分别较常规区提高5.95、1.11和12.59个百分点,肥料的增产效应为N>P>K,配方施肥区可增加效益504元/hm2。[结论]配方施肥较常规施肥更有利于小麦对肥料的利用和小麦的增产增效。
[Objective] Study on the yield increasing effect of formula fertilization in wheat. ]Method] The test was set for formula fertilization plot and common fertilization plot, which was analyzed from yield, use ratio of fertilizer, and income. [Result] N, P and K use ratios of formula fertilization plot wheat were 5.95%, 1.11% and 12.59% higher than common fertilization plot wheat, the yield increas- ing effect were N〉P〉K, and the income of formula fertilization plot increased 504 RMB per hectare. [Conclusion] Compared with common fertilization, formula fertilization was more conducive to fertilizeruse, yield and income increasing of wheat.
