[Method] Effects of dairy cattle ma- nure and chemical fertilizer on fertility of soils grown with Cichorium intybus were in- vestigated through a pot experiment. [Result] After manure of dairy cattle was ap- plied, it can be concluded that organic matter, total N, total P, alkali-hydrolyzable ni- trogen, available P, activities of urease and invertase in soils increased by 0.14-1.28 times, 43.8%-79.7%, 17.4%-30.8%, 147%-188%, 7 times, 17.2%-38.5%, and 1.36%- 3.34%, respectively. Furthermore, organic matter, total N. urease and invertase activi- ties in group of M7F3 increased most; total P and available P achieved the best in group of M3F7. These indicated that the applied manures of dairy cattle would maintain and improve soil fertility, providing better soils for Cichorium intybus. [Conclusion] The research provides reference for recycling of cattle manures and construction of ecological cyclical pattern of ＂grass planting-cattle breeding-methane fermentation-returning of manures into fields＂.展开更多

Furthermore, contents and changes of soil nutrients were analyzed, and countermeasures for improving soil quality were proposed in order to protect and improve land comprehensive productivity and promote land resource sustainable use and agricultural sustainable development.展开更多
