Research on Cultivated Land Quality Restriction Factors Based on Cultivated Land Quality Level Evaluation

Cultivated land quality is an essential agricultural resource and production element. To increase cultivated in a targeted way, it crucial to understand the features of regional elements that constrain its quality. In order diagnose restriction factors affecting improvement grades conduct quantitative analysis factors, index model was used this study analyze distribution characteristics East Anhui, China. The results show there are six main area, which effective soil layer thickness, organic matter, acidity alkalinity, plough texture, irrigation capacity, drainage obstacle among first third fourth seventh alkalinity. key ninth tenth classes.
