| 1. | 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 |
| 2. | 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。 |
| 3. | 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。 |
| 4. | 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。 |
| 5. | 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。 |
| 6. | From the standpoint of soil ecology , the direct effects of allelochemicals from crop root exudates on soil biota ( bacteria , fungi , nematode etc . ) were specifically discussed , and the key function of allelochemicals from root exudates in soil was presented
还重点列举了一些作物根分泌的化感物质对土壤生物产生的直接和间接影响，阐明了根分泌的化感物质在土壤中所起的重要化感作用。 |
| 7. | His year just at the end of the harvest , lan jie not only retained a high stubble but she also enclosed the direct seeding area with no - tillage fields with help of the local government to protect the reserved crop stubble on the surface
今年秋收刚过，蓝姐就早早做好了准备，不仅收获时留了高茬，还在当地政府部门的帮助下，对将要实施免耕播种的田块进行了围封，以保护留在地表的作物根茬。 |
| 8. | Degradation dynamics of the herbicide butachlor were investigated in nonrhizosphere soil , and various crops rhizosphere soils with or without inoculation treatment . the population dynamics of the cultureable microorganisms capable of utilizing butachlor as sole c and energy source were estimated with most probable number method in the process of butachlor degradation
本文考察主要作物棉花、小麦、玉米、水稻等作物根际土壤、接种后根际土壤和非根际土壤中除草剂丁草胺的降解速率，同时采用最大可能数( mpn )法测定分析丁草胺降解过程中丁草胺降解菌的变化动态。 |
