clay porosity

用法例句

By analysis of sampled soil physical properties,compared that with bare area,the results show that: there is no certain change pattern between soil bulk density and soil porosity;the bulk of soil bulk density gets larger and the soil gets deeper,while the soil bulk density gets smaller at certain depth and the capability of sluice falls.

以徐州市三环路内4个城区的公园绿地土壤为研究对象,通过对其土壤的物理性状取样分析,同时与无植被覆盖的裸地进行对比,结果表明:该城区公园绿地土壤容重与孔隙度随时间无确定的变化规律;该土壤容重开始随土壤深度增加而减小,某一深度以后逐渐增加,而土壤孔隙度随土壤深度增加而增加,某一深度以后逐渐减小,土壤蓄水保水能力降低。

Plastic mulching or intercropping combined with pruning and fertilization not only increased the biomass yield of Japanese honesuckle ( Lonicera japonica Thumb) but also improved its water- and soil-conserving effect, for such management technologies decreased soil bulk density, increased soil porosity and enhanced the water-holding capacity of the soil.

对金银花采取地膜覆盖、间作的种植模式,结合修剪、施肥的管理技术,可有效降低土壤容重,增加土壤孔隙度,提高土壤贮水量,不仅增加了金银花的生物学产量,而且提高金银花的水土保持效益。

The results showed the evident existences of the vertical spatial variability of porosity in soils on mm-scale; the variability of the cultivated soil originated from a prairie soil was higher than that originated from a forest soil, and the variability has a negative relation with the soil porosity but a positive relation with the soil depth with the tillage horizon; however, the variabi.

结果表明,土壤孔隙度在 mm尺度上存在较为明显的变异;不同的土壤变异性存在一定的差异;变异性与土壤孔隙度呈反向关系,与土壤深度呈正向关系;在耕作期,变异性随时间呈现一定的波动趋势。

To study the main microbial processes contributed to N2O emission,enrichment technique was used to isolate autotrophic nitrifiers,heterotrophic nitrifiers/aerobic denitrifiers and anaerobic denitrifiers from vegetable soil,and two re-inoculating soils autoclaved were incubated at 30 ℃ under 30%,50%,100% WFPS(Water-f.

本研究主要是通过微生物分离手段加富培养菜园土中的硝化菌、厌氧反硝化菌和异养硝化/好氧反硝化菌,并在30%、50%和100%3种土壤充水孔隙度(指土壤体积含水量与总孔隙度的百分比,V/V)水分条件下进行无菌菜园土反接种培养实验,研究了不同水分条件下、不同土壤微生物类群的产N2O量。
