Eco-geochemical Characteristics of Muskmelon Root Soil in Planting Region of Hetao Irrigation Area of Inner Mongolia
摘要
Abstract
Objective] To evaluate the eco-geochemical characteristics and geochemistry conditions of root soil in muskmelon planting area, to evaluate the soil environment quality in Hetao Irrigation Area, and to provide scientific basis for the muskmelon planting in this area.[Method] root system soil sample and plow pan sample were collected from the main muskmelon planting area in Hetao Irrigation Area , so as to analyze the contents of heavy metal elements.By comparing with the Soil Environmental Quality Standard (GB15618 -1995), we determined whether the heavy metal elements in root system accorded with national standard.[Result] Heavy metal elements in root system soil had the maximum con-tent in recession flow area of Yellow River, followed with saline soil.The content of heavy metal elements in chestnut-brown soil was the mini-mum.Harmful elements As, Cd, Hg, F and Pb in anthropogenic-alluvial soil of upper and middle reaches of Hetao Irrigation Area showed en-richment characteristics in earth surface, with a certain zonation in vertical direction.Trace elements Cu and Zn and beneficial elements P, K2 O, CaO, MgO and Se showed depletion.In anthropogenic-alluvial soil of Ulansuhai Nu recession flow area of Yellow River, harmful elements As and Cd showed significant enrichment in root system soil of earth surface; while other elements showed depletion or was nearly background value.In soil of plow pan, both beneficial component and harmful component showed enrichment characteristics.[Conclusion] Hetao Irrigation Area has idea geochemical conditions; and the heavy metal elements in muskmelon planted in this area accord with the standard of national food and health standard.关键词
