查询词典 soils

The placement of 11 taxa, formerly sorted on the subgroup level of the Chinese Soil Genetic Classification System, in CST was elucidated in the paper. All these soils studieds are classified into 5 CST Orders: Anthrosols, Ferrosols, Argosols, Cambosols and Primosols, 5 CST Suborders: Stagnic Anthrosols, Udic Ferrosols, Udic Argosols, Udic Cambosols and Orthic Primosols, 15 CST Group and 23 CST Subgroups.

岩溶山区表土中7Be、137Cs、226Ra和228Ra地球化学相分配的实验研究表明，4种核素绝大部分（85％以上）存在于FeMn氧化物、有机质及残渣相中。

1 Water stored in soils. 2 One of the most important elements involved in pedological processes and plant growth. There are three basic form-: water adhering in thin films by molecular attraction to the surface of soil particles and not available for plants is termed hygroscopic water. b Water forming thicker films and occupying the smaller pore spaces is termed capillary water.

储藏在土壤中的水分，2）在土壤过程和植物生长中最重要的元素之一，有三种基本形态-：（s：a 藉分子间引力以薄膜形式附著在土壤颗粒表面的水分，不能被植物利用，称为吸湿性水， b形成厚的水膜填充在较小土壤气孔中，称为毛细管水。

The main pollutants from this chemical plant is perchloroethane, pentachloroethane, hexachlorobutadiene and HCB, and such pollutants are present in the soil with high densities, some as high as 1%- 95%, of which the perchloroethane is near the purity of the corresponding product, and especially this part of the soil contains comparatively high-density persistent organic pollutant HCB, which makes it suitable to be disposed of together with other soils. Therefore it is suggest that this part of soil should be separately dug out and transported outside of the site.

化工厂的主要污染物质是六氯乙烷、五氯乙烷、六氯丁二烯和六氯苯，土壤中上述污染物的浓度非常高，有些达到1%至95%，其中六氯乙烷接近相应的产品的纯度，特别是这一部分含有较高浓度的持久性有机污染物六氯苯，不利于与其它土壤混合处理，建议将这一部分单独开挖出来并运出场外。

Soils under Phyllostachys praecox stands with different cultivation histories are selected to study their content changes in chemical proprties and heavy metal elements.

为了解集约化经营雷竹栽培过程中土壤化学、生物化学性质和重金属含量的变化，分析了不同栽培历史的雷竹林土壤。

Al becomes a major factor limiting crop growth and yield when solubilized in acid soils to phytotoxic species Al3+, but the mechanism underlying the Al toxicity remains largely unknown.

铝毒是酸性土壤中植物生长发育的主要限制因子，但目前关于铝毒的生理学机制并不很清楚；另外，关于园林花卉的铝毒害研究尚未见报道。

Farm. In the past (until app. 25 years ago) pistachiodiversity was maintained high in the field through a number of cultivation practices, s.a. use of male varieties derived from seed, use of wild Pistacia species to boost pollination and hence the fruit setting, use of natural populations of wild Pistacia (P. atlantica) as rootstock due to their well known resistance to stony and calcareous soils.

最近在农场栽培无花果技术的改变更加导致作物的多样性减少。25年前，无花果多样性通过多种栽培保持在很高的水平（源于种子的雄性物种采用，野生开心果物种改善授粉的采用，自然野生开心果作为根茎的采用——因为他们已知很好的抵抗多石和石灰性土壤的能力，等等

It is revealed in the study that the heavy metal concentration of Pb,Cu,Zn in the leaves of urban trees (Sabina chinesis,Platycladus orientalis,Euonymus japonicus,Platanus acerifolia, Prunus cerasifera) is significantly related with the relative heavy metal contents in atmospheres of different urban regions of Yantai city, while no such relationship is found in heavy metal Cd, and that the heavy metal amounts of Pb,Cd,Cu,Zn in urban soils had no direct impacts on the heavy metal concentrations in leaves of urban trees.

通过对烟台市区不同大气污染区域绿化植物叶片中重金属Pb，Cd，Cu，Zn富积量和大气与土壤中相应重金属的含量研究分析发现，植物叶片中重金属Pb，Cu和Zn的富积量与大气中Pb，Cu和Zn的相对含量呈显著的正相关，而植物叶片中Cd的富积量与大气中重金属的相对含量相关不显著。
