摘要
通过测土配方施肥、农民习惯施肥对比田间试验,研究测土配方施肥对玉米产量、肥料效益的影响.结果表明：在不同类型土壤上,测土配方施肥与农民习惯施肥相比显著提高了玉米产量,玉米增产率2.62%-33.71%,增收1 261.69-5 293.74元/hm2,产投比在各试点均有所提高,平均提高4.48%.测土配方施肥有利于肥效的发挥,提高肥料的利用率,同时实现玉米增产、增效并节省投资,减轻过量施肥对环境的污染.
Field experiments of soil testing and formula fertilization and farmers used fertilizer were conducted to study effects of soil testing and formula fertilization on maize yield and fertilizer benefit.The results showed that in the treatment by formula fertilization could improve maize yield better than that by the farmer custom fertilization in different types of soil,the retain production of maize was increased by 2.62%-33.71%,the income was increased by 1 261.69-5 293.74 yuan/hm2 and the ratio of output to input had increased in average of 4.48% in all experiment points.Soil testing and formula fertilization can help to play fertilizer effect,improving the utilization of fertilizer and achieving the target of increasing maize yield and efficiency and cost savings and reduce environmental pollution caused by excessive fertilization simultaneously.
