通过土柱试验发现，硅酸盐细菌NBT菌株还具有保钾功能，供试土壤接菌处理后的土壤滤液中流失的钾比对照减少35.5-56.5％，经方差分析，差异达显著水平；另外，硅酸盐细菌NBT菌株与农药的相容性试验表明，无论在大田农药施用浓度和残留浓度内的丁草胺、绿黄隆、三唑酮粉、多菌灵、马拉硫磷等农药对NBT菌株没有抑制作用；乐果、甲基1605在大田施用浓度下，对NBT菌株有一定抑制作用，而在残留浓度下，对NBT菌株无明显抑制作用。

Chapter 3 and 4 researches soil depuratingfunction and rule to rainwater by soil columniation penetrating examination on the basis of the two former chapters.

确定了雨水中主要污染物的种类及其浓度变化范围，以及汇水面性质、气温、降雨强度、降雨量和降雨时间间隔等因素对雨水径流水质的影响。

The contrast experiment of adding the acclimated activated sludge in the soil stuffing columniation or not, indicates the soil sludge with acclimated activated sludge can get a better effect than that without it. That means it's a practical way to use the acclimated activated sludge consolidating microbial function.

在土壤填料柱添加驯化污泥与不添加驯化污泥的对比实验，实验结果显示添加驯化污泥的土壤柱在CODcr、BOD5的处理效果都高于不添加驯化污泥的，证实了利用驯化污泥强化土壤填料中微生物的作用是可行的。

Under certain conditions, the activation and migration of soil Cd were accelerated by the interaction of Pb and Cd and increased Cd uptake by wetland rice. The organic-bound Cd in rizhosphere decreased by 90%. These phenomena illustrates that the interaction is very important for the transformation of soil Cd fractions. Meanwhile, the interaction distinctly affected the composition of roots secretion and their coordination abilities with heavy metals, causing clear variation to Cd amount in root cortex and middle columniation.

在一定的实验条件下，Pb和Cd的交互作用促进了Cd的活化与迁移，增加了水稻地上部分对Cd的吸收，使根际土有机结合态Cd下降了90%左右，表明交互作用对Cd形态的转化是一个重要的控制因素；同时交互作用对根系分泌物的组成及其与重金属的配位能力有着明显的影响，使Pb、Cd在根系皮层和中柱中Cd的含量有明显变化。

There is a little pollutant except very little comedo. Because of using this production, the soil has been increased organic matter, cultivated soil and decreased losing of nutritions, increased the yield of crop. Augment the fixation of CO_2 and restore the environment.

与其他产品相比，一体化营养基在生产和使用过程中对环境的影响相对比较轻微，污染物排放量除了少量粉尘没有废渣、废水和废气排出：由于产品使用后增加了土壤有机质，培肥地力，减少了营养物质流失，提高了作物产量，增加了大气二氧化碳固定量，具有较大的环境修复效应。

The analyses of soil samples indicate that there are high values of physical clay fraction in arbor-bush-grass complex forest and apple orchard, which means strong capability to resist soil wind erosion.

3不同农地表层土壤机械组成分析表明，乔灌草地和苹果园地表层土壤物理性粘粒含量含量较高，说明其抗风蚀能力较强；葡萄园地和灌木林地表层土壤物理性粘粒含量较低，说明其抗风蚀能力较弱。

The research of the composite index number of soil quality in different soillocations suggests that, the soil quality index increases as the altitude of mountain slope location decreases.

不同坡位下土壤质量综合指数研究表明：土壤质量指数随山体坡面位置相对海拔高度的降低而增高。

The soil and water loss parts is extracted from this area by the difference of spectrum feature of soil and water loss area and other ground object, the conditional expression and the simple model.

利用水土流失区光谱特征与其它地物的差异性，建立条件表达式，并建立简单模型，即可把该区的水土流失区提取出来。

The results showed that there were significant Conics relations between nitrogen application rate and wheat yield in high and middle soil fertility level, but it was a linear correlation under low fertility soil.
