Evaluation of the nutrient content and fertility suitability on tobacco-growing soil in Baoshan city of Yunnan province
摘要
Abstract
Eight indices from 497 representative soil samples were collected to evaluate the nutrient and fertility suitability of tobacco soil in the Baoshan city,they are,pH,organic matter,alkali-hydrolyzable N,water soluble Cl,available P,available K,available B,available Zn.Member function and principal component analysis were firstly employed to process these data and define the weights of soil nutrients respectively,According to SFI,the city's soil fertility is divided into five levels (grade Ⅰ:SFI≥-0.70; grade Ⅱ:0.55 ＜SFI ＜0.70; grade Ⅲ:0.40 ＜SFI≤0.55; grade Ⅳ:0.25 ＜SFI≤0.40; gradeⅤ:SFI≤0.25),The results indicated that ① The pH,water soluble Cl,available P,available K content were at an appropriate level in Baoshan,while organic matter and hydrolytic nitrogen content were high in Tengchong,and available B,available Zn content was low in Longling; ② The pH,organic matter,alkali-hydrolyzable N,available P,available K,available B had little variation in space,while water soluble Cl in Longyang and Changning changed greatly,available Zn in Shidian changed greatly as well.③ The SFI had little change among counties,they varied from 0.51 to 0.62,with mean of 0.57 and with CV (coefficient of variation) of 25.02％.④The proportion of soil fertility grades (Ⅰ-Ⅴ) in Baoshan were 18.51％,36.42％,32.19％,11.87％,32.19％ respectively,where Ⅱ,Ⅲ accounted for the vast majority (68.61％),Ⅴ proportion is very small (1.01％).关键词
