稳定性长效复合肥在玉米上的施用效果

Effect of ENTEC Stabilized Compound Fertilizer on Maize Yield

2007年在吉林省和河北省研究了恩泰克稳定性长效复合肥对玉米产量的影响,比较了习惯施肥与恩泰克投入产出经济效益。结果表明,恩泰克比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%;恩泰克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,经济效益好,应用前景广阔。

The 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 in 2007, and benefit and cost at each site were estimated thereafter. The results showed that ENTEC increased maize yields over traditional fertilizer with percentage at 9%. Rate of nitrogen of ENTEC applied was less than that of traditional fertilizer, and times of fertilizer application were reduced. Although cost of ENTEC was higher than traditional fertilizer, the benefit of ENTEC was also higher in Jilin which compensated for the higher cost of ENTEC input. In summary, that fertilize maize with ENTEC is economical viable which offers a new perspective for maize nutrients management.
