板栗土壤中微量营养元素地球化学特征
Geochemical Characteristics of Medium and Trance Nutrient Elements in Soils of Chestnut Forest
摘要
Abstract
The Ca,Mg,Fe,Zn,Cu,Mn concentration in 0 — 20 cm and 20— 40 cm soil layers in soils of chestnut forest in Yan mountain were determined by the available form and BCR three-step sequential chemical extraction experiment. The activity, characteristics of nutrient elements forms distribution and transfer ability were analyzed. Results showed that the intercrop of chestnut and grain went against chestnut's absorption of trace nutrient elements. The activity of elements had no evident difference in intercrop soils, but Cu and Zn activity was higher in 0 — 20 cm pure chestnut soil layers than in 20 — 40 cm. Two soil subtypes and different growth pattern had little influence on the distribution characteristics of trace nutrient elements forms. The main form of Cu,Zn,Fe in soils was residual. Mn was mainly associated with the deoxidized and residual forms, and the acetic acid extractable form of Mn was higher than other elements. The transfer ability of elements in chestnut soils was Ca>Mg>Mn>Cu>Zn>Fe.关键词
