Effect of root system on metal fractionation in rhizosphere of contaminated soil 不同作物根际环境对土壤重金属形态的影响
The tested strains are classified into 11 species of 4 genera , and their distribution in the rhizosphere is analyzed 对各菌种在作物根际的分布情况进行了分析。
5 . translocation and distribution pattern of ions in the rhizosphere soil of crops were different remarkably with respect to different re treatments and culture condition 5因不同处理及旱作和淹水条件的差异,作物根际离子的迁移方式有较大不同。
Biomasses of the microorganisms in crops rhizosphere soils were significantly higher than that in the nonrhizosphere soil , and depended significantly on the characteristics of plant species 根际土壤中丁草胺降解菌的生物量高于非根际土壤,各种作物根际土壤中降解菌的生物量依赖于植物种的特性。
The planting of crops amend the root - zone environment and augmented the depletion of butachlor in various crops rhizosphere soils and crops rhizosphere soils with inoculation conduced to enhance degradation of butachlor in soil . it could be dr 试验结果表明,植物根际是实现农药快速降解的微环境,在作物根际土壤接种降解菌可以强化农药的降解作用,是实现污染治理的一种有效途径。
