摘　　要：为应对安徽阜南县玉米种植中出现的生长异常现象,对研究区部分试验点玉米生长过程中的空秆、秃尖、花粒、缺粒等异常现象展开实地调查与分析。调查发现,异常气候、不合理的播期选择、过度密植及田间管理不善等因素是导致玉米出现生长异常现象的主要原因。为此,提出了选择适宜播期、合理密植、加强肥水管理、综合防控病虫害、人工辅助授粉与小型无人机辅助散粉相结合,以及适期晚收等应对措施,以减少生长异常现象发生率。本文为提高玉米种植产量与整体效益提供参考。In response to the abnormal growth phenomena in corn planting in Funan County,Anhui Province,field investigations and analyses were conducted on some experimental sites in the study area to investigate the abnormal phenomena such as hollow stalks,bald tips,flower grains,and missing grains during the growth process of corn.The investigation found that abnormal climate,unreasonable sowing date selection,excessive planting density,and poor field management are the main reasons for the abnormal growth phenomena of corn.Therefore,measures have been proposed to reduce the incidence of abnormal growth phenomena,such as selecting a suitable broadcasting date,planting reasonably,strengthening fertilizer and water management,comprehensive prevention and control of diseases and pests,implementing a combination of manual assisted pollination and small scale unmanned aerial vehicle assisted powder dispersal,and timely late harvesting.This article provides a reference for improving the yield and overall benefits of corn cultivation.
