Abstract:
With the theory of crop’s effective nutrient area,an experiment was conducted to identify whether effective plant and row spacing(EPRS) was suitable for soybean production.The results showed that EPRS of soybean was 47.0~63.4 cm in the central of Heilongjiang province.Therefore the 67~70 cm of ridge width in the present farming system has exceeded EPRS,which could waste soil resources.It was suggested that 55 cm of the row width of soybean should be benefit for the increase of population yield,especially in the central and south of Heilongjiang province.This theory provided a scientific evidence for the increasing area of narrow ridge farming system in the north of Heilongjiang province
