伴能肥料增效剂对甜玉米田间肥效试验.doc伴能肥料增效剂对甜玉米田间肥效试验摘要:为探索伴能肥料增效剂在甜玉米生产上的增产作用及其与氮肥最佳搭配和使用技术, 以期为大面积生产应用提供科学依据, 进行伴能肥料增效剂对甜玉米田间肥效试验。试验结果表明, 在甜玉米生产常规施肥水平基础上, 667m2 用伴能肥料增效剂 170ml 与尿素混合充分拌匀一次性基肥沟施培土, 能够起到延长有效供氮作用, 可满足甜玉米生长各个时期对氮肥的需求, 节省氮肥用量及追肥人工成本, 促进鲜苞产量和质量显著提高, 667m2 产量可达 , 增产 , 增加纯收入达 405. 3 元,实现甜玉米增产增收的经济效益。关键词:伴能肥料增效剂;甜玉米;增产效果中图分类号: S513 文献标识码: A 文章编号: 1003-4374 ( 2015 ) 02-0004-04 A field fertilizer effect experiment of energized fertilizer synergist on sweet maize Gan Qi-fan ( Hengxian plant protection and quarantine station , Nanning Guangxi 530300 , China ) Abstract : In order to explore the yield-increase effect of energized fertilizer synergist on sweet maize , bination with N fertilizer and application technology , to provide scientific supporting for large-scaleproduction , an experiment was conducted. The results show that on the basis of traditional fertilization level , synergist of 170 ml/667m2 mixed with urea as basic fertilizer can promote fresh nihlet yield and quality ohvi-ously7 with the yield of kg/667m2 and increase of kg and ee , so as to real-ize yield-increase and e-increase of sweet maize.
