      abstract = {The data of cultivated land quality monitoring sites, and  the current situations and evolution trend of soil organic  matter in cultivated land in Northeast China were analyzed.  Then, the causes for low organic matter content were  discussed. Finally, it came up with pertinent soil  improvement recommendations, including actively promoting  the quality protection technology model of cultivated land  such as straw returning in accordance with local  conditions, expanding organic fertilizer sources and  increasing application of organic fertilizers, implementing  reasonable crop rotation, planting green manure crops such  as legumes, and realizing the combination of land use and  land cultivation, establishing a reasonable fertilization  system, combining organic and inorganic fertilizers with  scientific fertilization, increasing fertilizer efficiency  and reducing the application of chemical fertilizers,  increasing financial investment and promoting the  integration of funds related to cultivated land  protection.},
