Abstract:
We studied the effects of different cultivations on soil physical properties and soybean growing index in albic soil in the east of Heilongjiang province. We set four treatments, they were wide ridge(WR), small ridge(SR), plain sowing(PS) and normal ridge(NR). Results showed that effects of different cultivations on soil bulk density and soil rigidity were significantly, soil bulk density of PS increased larger than other treatments, soil rigidity increased with soil depth increasing. Meanwhile, each treatment had different effect on soybean growth index, its influence on number of root nodule was much bigger, BR was the most one, SR was the least. Effects of different cultivations on soybean yield were significantly, BR and NR were much higher. The cultivation of BR could improve soil physical properties and increase the number of root nodule and soybean yield.
