- Salinity refers to the total concentration of salts present in the soil solution. 含盐量是指土壤溶液中所存在的盐类的总浓度。
- The mineral elements from the soil that are usable by the plant must be dissolved in the soil solution before they call be taken into the root. 土壤中可被植物利用的矿物质必须溶于土壤液中,然后才能被根部吸收。
- The mineral elements from the soil that are usable by the plant must be dissolved in the soil solution before they can be taken into the root. 土壤中可供植物利用的矿物成分,必须溶解在土壤中才能被根部吸收。
- This is also true for P and K in which supplementing the soil solution during peak demand periods is helping to avoid mid-season deficiencies. 对P和K也一样，在作物需求高峰期，增加土壤溶液的磷、钾浓度有助于避免在作物生长中期的养分缺乏。
- Basing on the albic soil in Mingguang area of Anhui province, this paper deals with the element composition and motivation property of soil solution. 以安徽省明光地区白浆化土壤为例,分析土壤溶液元素的组成与迁移特征。
- Soil solution samples were obtained by centrifuging fresh soil samples.Results show that the concentration of DOC in soil solution was signi... 土壤溶液与土壤固相间保持动态平衡,且能反映土壤的最新动态。
- The newly developed. in which soil solution was pressured out from orlginal soil using the homemade squeezer, imposed good stability and reliability. 试验结果表明，采用自行研制的电动土壤水压榨取样仪进行土壤水压榨取样，样品的重复性良好。
- To take the soil water potential of 3.0 bar as a critical value, the availability of nutrients in soil solution was higher at levels below 3.0 bar than over 3.0 bar. 以3.;0巴作为一个临界线;当土水势小于3
- A second more modern strategy to CRN involves use of soil enzyme inhibitors as a means of reducing large one-time releases of soluble nitrogen to the soil solution. 另一种比控释氮肥（CRN）更先进的方法是用土壤酶抑制剂来降低可溶性氮肥一次性大量释放到土壤溶液中。
- In effect, free-living nitrogen-fixing organisms are in situ green manures since most N derived from BNF is released to the soil solution only after cell death. 它们固定的氮素只有在细胞死亡后才能释放出来。因此，在事实上它们是原位绿肥。
- Yield will also be enhanced at the other extreme, when N in the soil solution is maintained at levels high enough throughout crop growth to nearly eliminate BNF. 另一种极端情况是当土壤溶液中的氮素在作物整个生长过程中保持在足够高的水平而几乎抑制了生物固氮时，产量也将会提高。
- Drainage water analyses may not indicate the composition of soil solutions accurately. 排水分析不能正确地反映土壤溶液的组成。
- SummaryThe characteristic of NO3--N accumulation in the soil layer of 40~220 cm with different amounts of nitrogen application was studied by analysis of NO3--N in soil solution collected in a cinnamon soil of the Piedmont Plain of Mt. Taihang. 通过采集土壤溶液并测定其硝态氮(NO3--N),对不同施N处理下40-220cm土层的NO--N累积特征进行了研究。
- After 90d mixing with soil, with treatment of Pb(NO3)2 and PbO, the proportion occupied by Pb2+ could be high reaching 75.23%, and related with lowering of pH value and DOC content of the soil solution. 与土壤混合90d后;Pb(NO3)2和PbO处理下Pb2+所占比例可高达75.;23%25;这可能与土壤溶液pH值和DOC含量降低有关
- Soil solute transport as affected by irrigation is, at present, an important research area in soil physics, environmental sciences, and geohydrology. 灌溉对土壤养分运移理论的研究是目前土壤物理学、境科学和农田灌溉学研究的一个重要方面。
- Some plants push their roots deep into the soil. 一些植物的根深深长入土中。
- Such crops won't grow in limy soil. 这类作物不能在石灰质的土壤中生长。
- What shall we grow in this alkaline soil? 我们应该在碱性土壤里种什么？
- There are a lot of worms in the soil. 泥土中有许多蠕虫。
- Water has permeated (through) the soil. 水已渗遍那片土壤。
