摘    要:种植密度对农作物尤其对玉米是一个重要的栽培技术指标,密度对倒伏和产量有重要影响。倒折率与倒伏率是玉米生产最主要的灾害因素,近年风伴雨造成的倒伏现象频发,给玉米生产带来绝产、减产或难以机械化收获的问题。因此研究玉米种植密度对倒伏及产量的影响具有重要意义。本研究以生产上3个主要推广的玉米品种为研究对象,通过不同密度种植,调查各品种抗倒特性,设计6个密度进行3次重复种植,旨在分析种植密度对玉米抗倒性状的影响规律,种植密度对玉米产量构成因素的影响规律,以及种植密度对玉米产量影响的大致数量程度,明确试验品种生产应用种植密度,以期为黄淮海地区玉米种植密度区间提供依据。

关 键 词:玉米;品种;种植密度;抗倒特性;生物产量

Abstract:Planting density is an important parameter for crops, especially maize.Density significantly affects lodging and yield. Lodging is a major risk factor in maize production. In recent years, the frequent occurrence of the fall phenomenon caused by wind and rain has led to issues such as crop failure, reduced yields, or challenges in mechanized harvest.Therefore, it is of great significance to study the effect of maize density on lodging and yield.Three main maize varieties in production were used as the research object to investigate the lodging resistance characteristics of each variety through different densities, with six densities applied across three repeated planting cycles.The aim of this study was to analyze the effect of planting density on lodging resistance, the effect of planting density on yield components, and the quantitative degree of the effect of planting density on yield.This analysis aims to provide a foundation for determining the optimal planting density interval of maize in Huang-Huai-Hai area.
Keywords:Maize   Variety   Planting density   Lodging resistance   Yield
