摘要
[目的]在吉林省中部地区玉米种植模式中实施精准农业,实现变量施肥。[方法]采用步进电机作为小型变量施肥机变量施肥系统动力,用4种代表性肥料作为试验材料,研究排肥轮长度、排肥轮转速和排肥量等因素。[结果]采取控制排肥轮转速和排肥轮长度的方式能够有效控制排肥量。[结论]该方式能够实现精准农业意义上的变量施肥,保证变量施肥系统的稳定性及精密播种准确性。
[Objective] Precision seeding was conducted to achieve precision agriculture in corn planting mode in central Jilin Province.[Method] Using step per motor as a fertilizer variable system,with four kinds of representative fertilizer as materials,length and rotate speed of fertilizer distributor and fertilizer amount were studied.[Result] The fertilizer amount could be controlled by the technique of controlling the length and rotate speed of fertilizer distributor.[Conclusion]The technique could achieve variable fertilization in the sense of precision agriculture,and ensure the stability of variable system and the accuracy of precision application.
