In order to clarify the relationship between the different types of paddy subsoil characteristics and yield,a pot experiment was used to study the effects of the subsoil from albic paddy soil，black paddy soil，meadow paddy soil of impact on rice growth characteristics and yield.The results showed that:For the chlorophyll content of rice,there were differences in tillering stage and heading stage,but no significant difference in mature stage,the order was meadow soil>black soil>albic soil,and the chlorophyll with subsoil treatment was signicantly higher than no subsoil.The plant height in different types of soil with subsoil treatment was higher than those without subsoil,but the difference was not significant.The dry matter in mature stage of the black soil,the meadow soil,albic soil were 245.66,239.13,182.77 g/pot,respectively,and the subsoil treatment was higher than no subsoil.There were significant difference in different soil types for rice vertical root length，the order was black soil>meadow soil>albic soil,and the subsoil treatment was higher than no subsoil.The root dry weight in subsoil treatments was higher than those without subsoil.There were significant differences in rice yield,the yields for black soil,albic soil and meadow soil were 143.84,136.56 and 131.56 g/pot,respectively,and the yields in suboil treatments were higher than no subsoil.The black soil subsoil yield contribution rate was the hightest,which was 24.8%,and in meadow soil and albic soil were 9.6% and 5.9%,respectively.
