摘　　要：为了探讨不同缓控释剂对玉米生长发育及产量的影响,通过在马山县乔利乡的田间试验,系统评估了4种不同缓控释剂(常规尿素、树脂包衣尿素、硝化抑制剂和脲酶抑制剂)对玉米生长的效果。结果显示,脲酶抑制剂(C处理)表现最优,显著提高了玉米的株高、穗粗、穗长和穗粒数,较对照组分别提高了13.70%、7.11%、8.06%和11.22%;树脂包衣尿素(A处理)次之,而硝化抑制剂(B处理)效果最差。产量方面,脲酶抑制剂不仅显著提高了玉米的百粒质量和总产量,较对照组分别增加了33.03%和17.16%;树脂包衣尿素和硝化抑制剂的增幅则相对较低。The aim of this study was to investigate the effects of different slow release agents on the growth and yield of maize.The effects of four different slow release agents on the growth of maize were systematically evaluated through a field experiment in Qiaoli Township.The results showed that urease inhibitor(treatment group C)had the best performance,and significantly increased the plant height,ear diameter,ear length and kernel number per ear,which were increased by 13.70%,7.11%,8.06%and 11.22%,respectively,compared with the control group.Resin-coated urea(treatment group A)was the second most effective,while nitrification inhibitor(treatment group B)was the least effective.In terms of yield,urease inhibitor not only significantly increased the 100 grain weight and total yield of maize by 33.03%and 17.16%,respectively,compared with the control group,but the increase of resin-coated urea and nitrification inhibitor was relatively low.
