Corn Nutrition Analysis and Characteristics of the Migration of Black Soil Arable Land with Soil Erosion in Songnen Plain
Corn has a very high value of use, rich in nutrients, such as fat, protein, carbohydrate and other nutrients;
calcium, iron, zinc and other minerals. In recent years, corn must be widely favored. Its total phenols,
anthocyanins, flavonoids and antioxidants can regulate blood pressure, blood lipids, and play an antioxidant role.
This paper analyzes the corn nutrition and characteristics of the migration of black soil arable land with soil
erosion in songnen plain. The black soil area of the songnen plain is an important food production base in our
province. Using remote sensing and geographic information technology, the characteristics of black soil
cultivated land in Heilongjiang Province from 2000 to 2019 were investigated. The area change amount, change
path and change level were comprehensively analyzed, which provided technical support for guiding the
protection of black soil arable land and the prevention and control of soil erosion.
