摘要
采用层次分析法和综合指数法,对新疆棉区9个典型棉田进行土壤质量评价研究。结果表明,全氮、碱解氮、速效磷、有机质是影响新疆棉田土壤质量的主要因素,速效磷是其中的限制因子。高产和中产棉田土壤利用强度大,可加强土壤施肥管理,提高土壤生产力。
Xinjiang is one of the Chinese cotton production regions. Two basic questions, namely, how the soil quality is and how the cotton field can be sustainable utilized are the key of the oasis area agricultural development. In the present study, analytic hierarchy process and the compre- hensive exponential methods were adopted to study 9 typical cotton field samples. The result in- dicated that total nitrogen, Available nitrogen, Available-phosphorus, the organic matter are the primary influence factors of the oasis cotton field quality, Available-phosphorus is the main limit factor. The intensity of soil use for higher and middle production cotton field is bigger, and it is necessary to apply the fertilizer management measure to strengthen the soil use and to enhance the productivity of cotton field.
