摘要
Abstract
97 sampling sites were set in the tobacco-growing area of Cili county by GPS techniques,and the contents of main nutrients in the top 20 cm of plowing layer of soil were determined,and then the characteristics of soil nutrients and its relationship with soil texture were analyzed by classic statics method.The results showed that the pH of tobacco-grow-ing area of Cili county was suitable,and mainly showed subacidity and neutral.The content of organic matter was appropri-ate,and the suitable proportion reached 55％,while there was greater change among towns.The contents of hydrolyzable ni-trogen,total N,total K,available K and available P were at appropriate level,while content of total P was lower.The soil texture was closely related to the pH,hydrolyzable nitrogen and macro-element,and the suitability ranking among different soil textures showed loamy clay>silty clay loam soil>silty clay>clay loam.关键词
