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。
Allelochemicals are the predominant constituents identified from root exudates , which have physiological and biochemical functions and take effect on soil biota 摘要植物根系分泌物包含多种功能次生物质，其中化感物质是具有重要生理生化功能的一类物质，这些化感物质释放到根际，能够对土壤生物产生影响。
The effects of oxygen supply in the rhizosphere on the eh ( oxidation reduction potential ) of soil and rice yield in planting troughs were studied , with the hybrid rice combination you 7954 as the material 摘要以杂交稻组合优7954为材料，研究根际供氧对稻田土壤的氧化还原电位及水稻产量和物质生产的影响。
The data showed that degradation of butachlor could be enhanced greatly by the vegetations of various crop . however , enhancement varied with crop species in the turn of cotton , rice , wheat , corn 表明由于根际效应的存在，作物的种植对丁草胺的降解具有明显的促进作用，其促进效果依次是棉花>水稻>小麦>玉米。
