摘要
田间研究了灌溉施肥中加入硝化抑制剂稳定性氮肥对香蕉产量和品质的影响。结果表明:恩泰克稳定性氮肥处理香蕉单株产量25.2 kg/株,折合产量54.8×103kg/hm2,比对照增产11.0%;香蕉果指数比对照增加15个/株;处理的香蕉可食部分、可溶性糖和Vc指标略高于对照;新型硝化抑制剂3,4-二甲基吡唑磷酸盐在灌溉施肥中具有广阔的应用前景。
Ecological nitrogen technology（ENTEC）,a stabilized fertilizer with a nitrate inhibitor,can reduce nitrogen application rate by less nitrate leaching and save labor in European for many crops.In order to reduce nitrogen rate and save labor input in China’s banana production,a field experiment was carried out in Nanning to investigate the effects of ENTEC on the yield increase of banana and its quality improvement,and the benefits and cost analysis was estimated thereafter.The results showed that ENTEC increased banana yields over traditional fertilizers management by 11%,the rate of nitrogen from ENTEC applied is less than that from traditional fertilizers at 200 g N per plant.Although cost of ENTEC is higher than that of traditional fertilizers,the benefit of ENTEC is also higher which compensates for the higher input cost of ENTEC.In summary,that fertilized banana with ENTEC is economical viable which offers a new perspective for banana nutrients management under fertigation.
