Study on Adsorbing Traits and Availability of Soil NutrientElements in Kuitun Cotton Field,Xinjiang
[目的]研究新疆奎屯垦区棉田土壤养分吸附与有效性,为该地区合理施肥提供理论依据.[方法]应用土壤养分状况系统研究法,通过土壤分析、吸附试验和盆栽试验,系统地研究奎屯垦区棉田土壤的养分状况、土壤对主要养分的吸附固定能力和生物有效性.[结果]3种类型棉田土壤K、P、Cu、Mn、Zn拟合曲线均达到0.05显著水平,其固钾和固磷能力依次为草甸土＞风沙土＞灰漠土；钾肥的增产作用并不是很显著,3种棉田土壤中较为缺乏的元素是N和P,3种土壤的OPT处理每盆吸钾…查看全部>>
[Objective] The kinetic of the potassium adsorbing traits and the availability of soil nutrient elements of the cotton field soil in Kuitun was studied to provide the basis for the utilization of the fertilizer. [ Method ] ASI systematic approach was applied with the soil analysis, adsorption experiment and pot experiment. The adsorbing ability of the soil to nutrient elements and the bio-availability of nutrient elements were studied by systematic approach …查看全部>>
