以章丘大葱产区生态地球化学调查为基础,采集了表层土壤、大葱、根系土及出露的代表性岩石样品,实测了大量和微量营养元素的含量,查明了研究区土壤地球化学背景。通过计算大葱对土壤营养元素的吸收率及大葱品质与营养元素的相关性分析,查明了大葱生长的特征营养元素为N,K2 O,Zn,B,P,Cu,Mn。在岩石土壤大葱这一生态体系中,营养元素在土壤中保持一定的储备和积累,为大葱的生长提供了有利的农业地球化学环境。
以章丘大蔥產區生態地毬化學調查為基礎,採集瞭錶層土壤、大蔥、根繫土及齣露的代錶性巖石樣品,實測瞭大量和微量營養元素的含量,查明瞭研究區土壤地毬化學揹景。通過計算大蔥對土壤營養元素的吸收率及大蔥品質與營養元素的相關性分析,查明瞭大蔥生長的特徵營養元素為N,K2 O,Zn,B,P,Cu,Mn。在巖石土壤大蔥這一生態體繫中,營養元素在土壤中保持一定的儲備和積纍,為大蔥的生長提供瞭有利的農業地毬化學環境。

Based on agricultural geochemistry survey of green onions plantation field in Zhangqiu area, collecting the samples of topsoil, green onions, root soil and representative outcropped rocks, contents of major elements and nutrients have been tested, and geochemical background of soil in studying area has been identified. Through cal-culation of absorption coefficient and correlation analysis between green onion varieties and nutrients, it is showed that N, K2 O, Zn, B, P, Cu, Mn are the specific nutrient elements. Through analyzing the migration and mass bal-ance of nutrient elements in rock-soil-green onion ecologic system, it is found that certain reserve and accumula-tion of nutrient elements in soil will provide beneficial geochemical environment for the growth of green onion.
