Grade of soil nutrients and their correlation with organic matter in apple orchards in Luochuan
摘要
Abstract
In Luochuan County ,Shaanxi province where was a suitable growing area of apple ,different orchards were chosen to analyze the grade of soil organic matter ,total N ,total P ,total K ,available nutrients and trace elements . The results showed that the levels of soil organic matter ,total N and available N were low ;the coefficient of variation (CV ) of soil available P was high ,and it was accumulated in some orhards ;the content of soil available K was high . The content of trace elements such as Fe ,Mn ,Cu and Zn was low ,in which the shoratge of Zn was most remarkable , and the CV of soil available Cu was relatively high .The soil organic matter was very significantly correlated with total N , available N and available P ,and was significantly correlated with available Fe and Zn ,but was not significantly correlat-ed with available Cu and Mn .The yield of orchards increased with the increase of soil organic matter content .关键词
