[Abstract]
Based on cultivated land evaluation of the Tiaoshan farm, the types of medium-low-yield field and types of classification, the result shows that the medium-low-yield field area is 73.2% of the total area of farm land, the middle and low production, respectively, 49.0%、 24.2% of the total area of farm land; Middle field is mainly distributed in central and southern region, medium-low-yield field mainly distributed in a mountain in northern regions; The medium-low-yield field types are drought and barren fertilizer irrigation, and according to types of improvement measures are put forward.
