Study on Adsorbing Traits and Availability of Soil NutrientElements in Kuitun Cotton Field,Xinjiang
摘要
Abstract
[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 systematically in main cotton soil types. [Result] The potassium,phosphorus,copper,manganese,zinc fitting curves was significant in three types of cotton soil,and the capability of adsorption K and P were MS > GS > AS. The increases amount wasn't salience used K, N and P which were lack in the cotton field. The amount of adsorption K of OPT was more than that of CK, and fertilizer use efficiency of CK was lower than that of OPT. [ Conclusion ] The content of soil potassium were higher in Xinjiang cotton field, so potassium couldn' t be used in theory. Some iron could be used in MS,and some zinc could be used in GS and AS. The application of NPK and trace elements could significantly improve the utilization efficiency of the potassium.关键词
