Abstract
Taking rice variety Huaidao 5 as the research object,effects of different amount of straw returning on rice yield and soil nutrient were studied.Results showed that:compared with half-amount straw returning,the rice yield was increased under total-amount straw returning,but the difference was not significant;the content of soil organic matter,alkali-hydro nitrogen,available phosphorus were increased under the two amounts of straw returning,but the effect of total-amount straw returning was better,the content of organic matter and available phosphorus increased more than10%,enriching the soil fertility effectively.
