摘  要：
针对玉米传统施肥中分次施用且氮利用率低的问题,2006年在吉林、河北研究了新型稳定性长效复合肥ENTEC一次施肥对玉米产量的影响,比较了农民习惯施肥与推荐施肥投入产出经济效益。研究表明:推荐施肥比农民习惯施肥降低了氮肥用量,玉米产量与习惯施肥相当或略有增加,增产幅度9%;含硝化抑制剂复合肥一次施用即可满足玉米整个生育期的需求,可减少施肥的劳动力投入,经济效率高,应用前景广阔。

摘  要：
ENTEC,abbreviation for ecological nitrogen technology,which is compound fertilizer with nitrate inhibitor from BASF Germany,can reduce nitrogen application rate by less nitrate leaching and save labor in European for many crops,but little experience in China maize production.In order to reduce nitrogen rate and save labor input in China maize production,field experiment was carried out in Jilin and Hebei to investigate the effects of ENTEC on yield increase for maize at main maize production areas,and benefits and cost at each site were estimated thereafter.The results showed that ENTEC increased maize yields over traditional fertilizer in Jilin with percentage at 9%,but kept the same yield of maize in Hebei.Rate of nitrogen of ENTEC applied was less than that of traditional fertilizer,and times of fertilizer application were reduced,which results in labor saving.Although cost of ENTEC was higher than traditional fertilizer,the benefit of ENTEC was also higher in Jilin which compensate for the higher cost of ENTEC input.In summary,that fertilize maize with ENTEC was economical viable which offers a new perspective for maize nutrients management.
