The agriculture soils of Baimahu ,Lushan and Zoujiao are the typical cases in the suburbs of Changde. Rice soil and vegetable plot are the two typical agriculture soils, we collected 6 samples according to the scientific method in these three areas. After air dry, contuse, screen and make soil samples, we tested their 9 indexs of PH, organic-substance, total phosphorus, quick-acting phosphorus. Then analysed the fertility condition of these areas. Then apply feasible suggestion of fertilizer after putting forward science and suiting measures to local conditions etc, by Compare with the documents and materials.

白马湖，芦山乡和陬郊的耕作土壤是常德市郊区耕作土壤的典型代表，在这三个地区分别就水稻土和菜地这两个基本的土地耕作类型按科学的方法共采集了6个样品，经过风干，研碎，过筛制成土样后，测定了它们的PH，交换性酸，有机质，全磷，速效磷等9指标，从而对该地区耕作土壤肥力状况进行分析，对比文献资料，总结分析结果，针对不同地区不同的土壤状况，提出了科学施肥，因地制宜等可行性建议，尤其是对TAS—986型原子吸收分光光度计用火焰法测钾的条件作了深入的探讨。

In order to analyze the influence of the center air pipe diameter change on the combustion effect, numerical modeling was applied to numerical calculation on the temperature field of such type of boiler,through which temperature field in five different schemes were obtained. In addition, the influence law of change of the diameter of the center air pipe on the temperature field was analyzed. The temperature of the nearly-back wall region takes on a firstly decreasing and then increasing change with the diametrical decrease of the central wind pipe.

为研究改变中心风管直径后的4层燃烧器对炉膛燃烧的影响，采用数值模拟的方法对该型锅炉炉内的温度场进行数值计算，得到5种不同方案下该型锅炉炉内的温度场分布，并分析了中心风管直径的改变对炉内温度场的影响规律，即后墙近壁区温度随着中心风管直径的减小呈现先降低后升高的趋势。
