0引言随着我国蔬菜生产的发展，设施蔬菜栽培面积不断扩大，由于设施栽培的特点是采用人工控制，使设施内部形成了一个特殊的生态环境，且多年连作和大量施用化肥，忽视有机肥使用等，使蔬菜生产出现了各种障碍问题，其严重影响了蔬菜生产和农民收益，并成为制约蔬菜生产可持续发展的瓶颈问题。

The result indicated that, although microorganism from paddy soil could directly reduce Cr, the reduecing rate and efficiency were limited; the higher Cr concentration was, the less reducing ability the microbial showed; the microbe from different paddy soils had different effects on Cr reducing abilities; The reducing ability of the microbe from Sichuan paddy soil was higher than that from Jiangxi paddy soil. Cr added could be rapidly reduced in paddy soil under anaerobic incubation, moreover, the process of dissimilatory iron reduction of soil could obviously promote the Cr reduction. The existent of Cr could delay the appearance of Fe; the higher Cr concentration was, the later Fe appeared. The delayed time of Fe appearance was in accordance with the ending time of Cr reduction.

结果表明，由水稻土中提取的微生物虽然能够直接还原Cr，但其还原速率和还原程度有限，且Cr浓度越高，微生物的还原能力越差；不同来源的上壤微生物对Cr的还原能力有所差异，其中四川水稻土中微生物对Cr的还原能力均大于江西水稻土；在厌氧培养的水稻土中，添加的Cr可以较迅速地还原，其中土壤氧化铁的微生物还原过程对Cr还原具有明显的促进作用；Cr的存在导致Fe生成的时间出现滞后，目Cr浓度越大生成Fe的滞后时间越长；Fe产生滞后的时间与Cr还原结束的时间具有一致性。

The result showed that 6 kinds of soil enzyme activities and soil microorganism quantity under the canopy of Tamarix spp.

Chapter three is the degradation of Abamectin in soils. The results show:(1) The decomposition of Abamectin is fastest in Aquic Cambosols while slowest in Udic Cambosols in five kinds of different soils.(2) Organic matter content in soil is the most important factor which influences the degradation half-life of Abamectin in soil, and their relative coefficient arrives at 0.9323, but pH value, total nitrogen, CEC and field maximum moisture capacity correlate little.(3) Soil organic matter, soil temperature and pesticide concentration can obviously affect Abamectin degradation in soil, in addition, the degradation half-life of Abamectin in sterilized soil is far more than that in non-sterilized soil, which maybe contributes to microorganism in soil. Chapter four is the microbial degradation of Abamectin.

第三章研究了阿维菌素在土壤中的降解，结果表明：(1)五种不同类型土壤中，阿维菌素在潮湿雏形土中降解最快，而在湿润雏形土中降解最慢；(2)土壤有机质含量与阿维菌素半衰期相关性较强，相关系数为0.9323，而土壤酸碱度、总氮含量、阳离子交换量和田间最大持水量等因子与阿维菌素半衰期相关性较小，说明影响阿维菌素在土壤中降解的最主要因子为有机质含量；(3)土壤有机质、土壤温度和农药浓度等因素对阿维菌素在土壤中的降解有较大影响，此外灭菌条件下其降解半衰期远大于未灭菌时的半衰期，这表明阿维菌素在土壤中的降解可能和土壤微生物有关。

As shown in the experimental results: as the conductor of petroleum biological degradation, the quantity of microorganism is the important factor of petroleum degradation efficiency, the huge natural capacity of microorganism in soil is its foundation of bioremediation; petroleum density in certain scope do not affect for the degradation efficiency of petroleum, and in the density of 5%, its initial degradation efficiency is higher, however after training 40 days, this kind of advantage change weak gradually, the reason may be the petroleum of high density probably having certain poison role for microorganism; the best ecological condition of petroleum contaminated soil bioremediation is that nutrition material C: N = 60, electron receives body HiOi joining quantity amount to 12 mg/g, water content is 50%, surface activator is anion surface activator of 12 Wan base benzene sulphur sour sodium; the relation of primary and secondary of factor is water content, surface activator, nutrition material and electron receiver.

试验研究结果表明：作为石油生物降解的执行者，微生物的数量是影响石油降解效率的重要因素，土壤中微生物的巨大的自然容量是其生物修复的基础；石油浓度在一定范围内对石油的降解效率并没有影响，并且在5％浓度时，其起始降解效率较高，但是到了培养40天以后，这种优势渐渐变弱，可能还是高浓度的石油对微生物有一定的毒害作用；石油污染土壤生物修复的最佳生态条件为：营养物质C：N为60，电子受体H_2O_2的累计加入量为12mg/g，含水量为50％，表面活性剂为阴离子表面活性剂十二烷基苯磺酸钠；因素的主次关系为：含水量、表面活性剂、营养物质和电子受体。
