    摘要:

    为验证“大配方、小调整”施肥模式在河南省的应用效果,于 2017~ 2018年在河南省扶沟县选择 8个典型地块,分为高、中、低 3种基础地力类型。结果表明,相比不施肥处理,农民习惯处理平均增产 30.0%,但高的施肥成本,使高肥力水平下的经济效益反而低于不施肥处理。与农户习惯施肥相比,配方肥处理减少了氮素投入同时提高了磷、钾用量,不同基础地力水平下,配方肥处理与农户习惯处理在产量上没有显著性差异;但低的施肥投入使经济效益提升了 16.6%。依据土壤速效磷、钾含量的差异,在大配方的基础上对肥料配方进行小调整,小调整处理的经济效益随基础肥力的上升不断增加,较农户习惯处理增收 31.3%。不同基础地力水平下,肥料贡献率、肥料农学利用率始终表现为农户习惯 <大配方 <小调整。由此可知,“大配方、小调整”可推动区域施肥技术的进步,促进肥料产品的优化,帮助农民节本增收。

    Abstract:

    In order to verify the effect of the“Regional Fertilizer Formula and Site Specific Adjustment”fertilization modelin Henan Province,eight typical plots were used in FugouCounty,Henan Province in 2017~2018,these plots weredivided into three types of basic soilfertilities:high,medium andlow.The results showed that compared with no fertilizertreatment,farmers’practice fertilization increased yield by 30.0% averagely,but the increase in fertilization cost in farmers’ practice treatment decreased its economic benefits compared with no fertilization treatment under soil with high basic fertility level.Compared with farmers’practicefertilization,formula fertilizer treatment reduced nitrogen input and increased phosphorusand potassiumdosage.Under soil with different fertilitylevels,there was no siginificant difference in yield between formulafertilizer treatment and farmers’practicetreatment,but the low input increased economic efficiency by16.6%.According tothe difference in soil available phosphorus and potassiumcontent,on the basis of the large formula,the fertilizer formula wasadjustedslightly,and the economic benefit of small adjustment treatment increased with the increase in basic soilfertility,which was 31.3% higher than that offarmers.Under different soil fertilitylevels,the fertilizer contribution rate and fertilizeragronomic efficiency differed as the farmers practice fertilization
