Theoretical analysis of black soil quality for the development of modern agriculture
Abstract
[Objective] Black soil is the material basis for modern agriculture development in Northeast China, and the advancement of modern agriculture has created a new demand for the quality of black soil land. By understanding the connotation, composition, and characteristics of black soil land quality for modern agriculture, we can objectively evaluate and monitor black soil land quality, which is the foundation for the promotion of high-quality black soil land. [Methods] This study was based on an analysis of the composition and function of black soil land, combined with the situation and demand analysis of modern agricultural development in black soil areas, and discussion on the composition of the cultivated land quality system, black soil land characteristics. The study aimed to establish a new research model of regional cultivated land quality and enrich the theoretical basis of cultivated land quality research. [Results] (1) The black soil land is a composite natural-artificial cultivated land system with black soil as the core element, which is composed of the black soil subsystem, the site subsystem, the facility subsystem, and the ownership subsystem. (2) Because the black soil land is multifunctional, its quality system consists of the basic fertility quality, facility guarantee quality, spatial form quality, and ecological environment quality, which jointly meet the needs of the high-quality development of modern agriculture. (3) Black soil land quality has the characteristics of multi-level system composition, multi-types of influencing factors, and multi-scale spatial differentiation. [Conclusion] The monitoring and evaluation of black soil land quality should fully consider its quality characteristics, and adopt the corresponding methods and means.
