Abstract: Bean-rice-vegetable cropping system plays an important part in Southern China, but the effect of straw returnuing on crops yield and soil fertility under which is unknown. A long-term field experiment was conducted for seven years (2009—2015) to investigate the effects of rice straw returning on soil fertility and crop yield in bean-rice-vegetable continuous cropping system on rice soil of Zhejiang province. The results showed that straw returning has a great effect on crop yield, rice and vegetable yield increased more than 10% every year compared with chemical fertilizer. Straw returning also had a great effect on soil fertility: improved soil organic matter, total nitrogen and available phosphorus and available potassium contents, and also soil pH. In addition, total nitrogen and available phosphorus and available potassium contents under straw returning area increased gradually every year. In conclusion, straw returning can improve crops yield and soil fertility in multiple cropping area and can be used for for a long time in agricultural practice.
