为了比较常规尿素与心连心化肥有限公司生产的几种新型肥料对玉米增产效果和养分利用率的差异,以玉米品种郑单958为试验材料,于2016年6月至2016年10月在河南省新乡市河南科技学院东区乔榭试验田进行大田试验,试验设无氮、常规尿素、常规尿素加锌、腐植酸尿素、控失尿素、聚能网尿素、控失尿素一次性施肥和含锌尿素共8个施肥处理.结果表明:在玉米考种结果和增产率方面,聚能网尿素增产率最高,控失尿素次之;在植株地上部分生物量和氮素、磷素养分累积方面,常规尿素加锌和控失尿素在生育后期表现出了明显的增长优势;在玉米籽粒品质分析中,控失尿素表现最好,其次是聚能网尿素和腐植酸尿素.聚能网尿素和控失尿素增产优势明显,且在生物量、氮磷养分含量、土壤无机氮含量及品质分析方面都表现良好,这两种新型尿素在玉米生产中有较大推广价值.
In order to compare the difference of yield increase and nutrient utilization efficiency of several kinds of new fertilizers produced by conventional urea and Xinlianxin Fertilizer Co., Ltd., the maize variety Zhengdan 958 was used as the experimental material, from June 2016 to October 2016 in Henan Xinxiang City, Henan Province, Science and Technology Institute of East China Jiao Se experimental fields for field experiments, the experiment set free of nitrogen, conventional urea, conventional urea and zinc, humic acid urea, controlled loss of urea, poly network of urea, A total of eight fertilization treatments.The results showed that: in corn test results and yield increase, poly energy network urea yield the highest rate of urea control; the aboveground biomass and nitrogen and phosphorus accumulation, conventional Urea plus zinc and urea control showed a significant growth advantage in late growth stage; in the analysis of corn grain quality, the performance of the best urea control, followed by the poly energy network urea and humic acid urea. Urea has obvious advantages in yield increase and good performance in biomass, nitrogen and phosphorus nutrient content, inorganic nitrogen content in soil and quality analysis, and the two new types of urea have a larger promotion price in corn production .
