种植模式的研究,在着重于产量效益的前提下,还应考虑到抗旱性、作业易难程度、省工省时等诸多因素,高水肥阴湿区和干旱半干旱区种植模式不能一通过该项试验,掌握在采用种植模式,马铃薯的产量变化情况,筛选出产量高,效益好的最佳模式,从而为大田推广提供理论依据 Under the precondition of focusing on yield benefit, the study on cropping pattern should take into account many factors such as drought resistance, ease of operation, labor-saving and time-saving, etc., and the planting patterns of wet and dry areas with high water, fertilizer and arid and semi-arid areas can not pass through Test, grasp the use of planting patterns, the output of potatoes, screening out the best model of high yield, good efficiency, so as to provide a theoretical basis for the promotion of the field
