Study on Cultivated Land Quality Monitoring and Changein Molidawa Daur Autonomous Banner

Objective] To understand the changes of cultivated land quality monitoring indicators in Molidawa Daur Autonomous Banner black land project area. Methods] Soil samples from 106 cultivated land quality investigation points in the project area were collected for three consecutive years from 2018 to 2020, and six main indexes such as soil organic matter, total nitrogen, available phosphorus, available potassium, bulk density and pH were detected and analyzed. Results] The research shows that the six main indicators of Molidawa Daur Autonomous Banner black land project area in 2020 are higher than those in 2018. Conclusion] The northeast black land comprehensive protection model of "black land nurturing and fattening" has achieved good implementation results and improved the quality of cultivated land in the project area.
