Abstract
A field experiment was carried out to study how nitrogen accumulation and yield of rice straw were affected by the measure of rice straw return to field under the application of nitrogen and biological decomposing agents.The results showed that rice straw could improve nitrogen accumulation of rice ear obviously.Compared with CK,both the total nitrogen accumulation and grain nitrogen accumulation were higher in the treatment of 2-year rice straw return.Different treatment levels also obviously impacted the rice yield: 2-year of straw return was significantly higher than 1-year of straw return,high-N treatment was significantly higher than the low one,and treatments with biological decomposing agents were better than those without.Of all the above treatments,the rice yield was highest in the treatment of 2-year straw return + high nitrogen + biological decomposing agents.Therefore,we concluded that this treatment was the best measure for rice straw return to field in northeastern China.
