Comprehensive Evaluation of Farmland Soil Fertility in Yanji City
摘要
Abstract
[Objective] Farmland soil fertility was studied to provide references for rational fertilization of farmland soil in Yanji City. [Methods] Collected 82 soils, including 57 corn farmland, 25 rice farmland, chemical analysis related to soil fertility was carried out,and then principal component analysis method was adopted to study classification of soil fertility and gave comprehensive evaluation in the region. [Result] The soil fertility index of farmland in Yanji City can be classified into 82 major components of the 4 evaluation factors, the corn samples values of IFI score was in the range of -1. 6432-1. 7320 by cluster analysis method, the rice sample value of IFI score was in the range of -1. 6731-1. 7129. [ Conclusion] This research can reflect the soil fertility standard of soil in a certain extent and can make a relatively correct evaluation of soil nu-trient supply capacity and abundance.关键词
