摘要
玉米从播种到成熟,经历若干个生育阶段和生育时期,在每个生育时期对养分的需求不同,总体呈先增长后下降的趋势,在大喇叭口期达到最大。根据玉米不同生长阶段的需肥特点,有针对性地施加追肥,是玉米高产与稳产的重要保障。本文对我国玉米追肥机械的研究现状进行梳理和总结,对不同种类追肥机械的工作原理和结构特点进行分析,并列出各类机型中具有代表性的机具和生产厂家。对我国玉米追肥机械的发展前景进行展望。
From sowing to mature, corn experienced a number of fertility and reproductive period. The demandfor nutrients of corn, which is totally different in each growth period, shows a downtrend after rising at the maximumin the period which corn grow exuberantly. According to corn characteristics of fertilizer requirement at differentgrowth stages, it is important to apply fertilizer pertinently with the aim to guarantee a high and stable yield of corn.The current research status of Chinese topdressing machinery of corn was generalized and summarized in this paper,besides the whole type Chinese corn fertilizer machines had been elaborated respectively from two aspects of rooffertilizer and top dressing. Therefore the development prospects of mechanical fertilizer were discussed.
