Improvement measures include four aspects: the original sowing date change “” “autumn” for the “summer”; planting methods to change the line width and width; planting density to thinning (165,000 ~ 210,000 plants · hm ~ (-2)) was suitable for close planting (330,000 plants · hm -2). The planting depth was changed to deep planting (25-30 cm deep) for shallow planting (15 cm deep furrow).
