定西市安定区为典型的黄土高原丘陵沟壑区,境内沟壑纵横,梁峁起伏,土壤发育程度弱,水土流失严重,土壤瘠薄,土壤产出率低,产品质量不高。随着城市化的发展、道路的建设、农业结构调整、灾害损失等,造成耕地面积逐年减少。在种植面积扩张有限的情况下,进一步提高土地产出率,提升产品品质,壮大农业产业发展后劲,土壤改良势在必行。
Anding District, Dingxi City, is a typical hilly and gully area in the Loess Plateau. There are ravines and rifts in the territory, undulating hills, weak soil development, serious water and soil loss, infertile soils, low soil yield and poor product quality. With the development of urbanization, the construction of roads, the adjustment of agricultural structure and the loss of disasters, the cultivated area has been reduced year by year. Under the circumstance of limited expansion of planting area, it is imperative to further improve land productivity, improve product quality and increase stamina in the development of agricultural industry.
