Abstract:

Reasonably guiding farmers to adopt technologies that can improve the quality of cultivated land is very important to increase soil fertility, improve soil health, and promote high yield and efficiency of crops. This study analyzed the factors influencing the improvement of cultivated land quality, reviewed the improving technologies, including straw returning, green manure planting, deep ploughing and subsoiling, organic fertilizer applying, formula fertilization by soil testing, lateral deep fertilization for rice, soil conditioner applying and water-fertilizer integrating, and summarized the advantages and disadvantages of these technologies and their applied measures. At present, the research mainly focuses on the integrated application of the technologies for improving cultivated land quality, the differences of farmers’ adoption of various technologies, and the industrial application of modern information technology platform and equipment. It is proposed that we should improve the formulation of standards for multi-function technologies, strengthen the information technology such as high-scoring remote sensing to monitor and evaluate the quality of cultivated land, boost the utilization efficiency of cultivated land resources and perfect the ecological compensation mechanism for farmers.
