不同有机物料与外源锌对土壤锌形态及生物有效性的影响
Effects of Different Organic Materials and Exogenous Zn on Zn Distribution in Soil
摘要
Abstract
A pot experiment with a complete combinatorial design of two factors was conducted to study the effects of different organic mate-rials and different concentrations of exogenous zinc on the soil total zinc, available zinc, zinc forms and zinc content distribution of pak-choi. The results showed that the total zinc, available zinc, and different forms of zinc contents in soil all increased as the concentration of exoge-nous zinc increased. Both lawn grass and maize straw decreased the total zinc, increased the available zinc and no-residual zinc in soil effec-tively, and promoted the accumulation of zinc in pak-choi. Chicken manure, pig manure, and cattle manure improved the total zinc, available zinc and no-residual zinc in soil significantly, and enhanced the activity of zinc in soil, and promoted the accumulation of zinc in pak-choi significantly. Peat and weathered coal both increased the organic zinc and residual zinc in soil effectively, decreased the total zinc and avail-able zinc, showing the passivating effect to zinc of soil, and failed to promote the accumulation of zinc in pak-choi. The concentration of zinc in pak-choi root increased as the concentration of exogenous zinc increased.关键词
