江淮一带，机条播在大面积生产上推开后，由于土壤类型复杂，秋播阶段连阴雨天机率高，以及各地三麦生产水平差异等因素的影响，机条播的单机工作效率偏低的问题也明显暴露出来条播机的利用率低，台机作业面积小（秋播多雨年份部分机搁置未用）已影响到机条播麦的进一步推广。
JAC area, the machine sowing on a large area to open the open, due to the complexity of the soil type, the autumn stage with cloudy and rainy rainy season, as well as the different levels of production capacity of three wheat and other factors, machine sowing the low efficiency of stand-alone work Obviously exposed the low utilization of seed drill, table machine small area of work (rainy autumn part of the machine shelved unused) has affected the further promotion of the machine broadcast wheat.
