摘　　要：以内蒙古伊金霍洛旗为试验地点,设置了A(化肥底施+追肥)、B(化肥底施)和C(缓释肥分层底施)3种处理,研究了缓释肥分层底施对玉米生长指标和产量指标的影响。结果显示:采用C(缓释肥分层底施)处理方式可以显著改善玉米生长性状,并提高玉米产量。与传统的B(化肥底施)和A(化肥底施+追肥)方式相比,采用C(缓释肥分层底施)处理方式的玉米穗粗、穗长和行粒数均显著增加,较A(化肥底施+追肥)方式的玉米穗粗、穗长和行粒数分别增加了4.43%、6.12%和8.60%。同时,C(缓释肥分层底施)处理方式还能提高玉米的出籽率和百粒质量,提升了玉米产量,相较于A(化肥底施+追肥)方式,处理C(缓释肥分层底施)处理方式的玉米出籽率提高了1.56%,百粒质量增加了6.03%,产量高出了6.69%。结果表明:缓释肥分层底施方式能够提供持续且均衡的养分供应,有助于玉米植株全面、健康地生长,从而实现更高的产量。The study on maize growth and yield indexes under different fertilization methods in Yijin Horuo Banner showed that the use of layered application of slow-release fertilizer could significantly improve the growth status and yield of maize.Compared with the traditional fertilizer base application and fertilizer base application plus topdressing,the grain number per ear,ear length and row number of maize were significantly increased under the slow-release fertilizer base application,thus increasing the grain number per ear and yield.The maize ear diameter,ear length and row number of maize in the treatment group C were increased by 4.43%,6.12%and 8.60%,respectively,compared with the treatment group A.At the same time,the method of fertilization can also improve the seed yield and 100 grain mass of maize,and further improve the yield.Compared with the treatment group A,the seed yield of corn in the treatment group C increased by 1.56%,the 100 grain mass increased by 6.03%,and the yield increased by 6.69%.The results showed that the layered bottom application of slow release fertilizer could provide continuous and balanced nutrient supply,which was conducive to the comprehensive and healthy growth of maize plants,so as to achieve higher yield.
