水分

In order to improve the water use efficiency under conservation tillage, the effects of subsoiling on soil moisture under no-tillage 2 years later was studied.

研究两年免耕后深松对土壤水分的影响，提高保护性耕作条件下对土壤水分的利用效率。

Based on the data of continuous field plot experiments for five years in Luoyang, the influence of four different tillage practices, namely reduced tillage, no-tillage, subsoiling and conventional tillage on the soil moisture, water use efficiency and crop yields of winter wheat was studied.

采用连续5a的田间定位试验资料，研究了洛阳地区休闲期4种不同耕作方式对冬小麦农田土壤水分变化、水分利用效率及作物产量的影响。

In 0-100cm soil depth, the soil moisture in 50-100 cm depth under subsoiling were higher compared with no-tillage, which increased when it was dry and scarce in rain and decreased when it was rainy with soil depth increasing.

在0~100cm的土层剖面上，50~100cm土壤水分含量深松显著高于对照，干旱少雨时，土壤水分含量随土层深度增加而增加；降雨集中时，随土层深度增加而减少。

The study shows that the bulk subsoil can increase the rate of infiltration greatly and improve the physical structure of soil and decrease the amount of water distribution along the slope again. Further more, the growth of Caragana in area that was subsoiled increased 50.15% compare to contrast region. This paper suggests that the technology of bulk subsoil should be spread in arid region and semi-arid region as well as bess plateau.

结果表明，全方位深松技术可以明显的提高土壤入渗性能，改善土壤物理结构，减少水分沿坡面的二次分配，间接起到消减坡度的作用；经过全方位深松处理的柠条林地的土壤入渗效果也有明显的提高，改善了林地的水分条件，从而促进了柠条的生长，试验期间内对照区柠条最大生长量为12cm，平均增长量为5.17cm，深松区最大生长量也为12cm，但平均增长量8.28cm，比对照区要高50.15％。

Water, even present, can be made less available by adding solutes such sugar and salt.

即使有水分存在，也可以通过添加溶质如糖和盐，来使水分具有更小的可利用性。

Soil water characteristic curve is one of important parameters for modeling waterflow and solutes transport.

0引言土壤水分特征曲线(soil water characteristic curve，SWCC)是表示土壤水吸力和土壤含水量之间关系的曲线，是模拟土壤水分运动和溶质迁移的重要参数之一。

Moisture content at all the soil depths was significantly higher (p≤0.05) in orange orchard than in forest on both the slopes.

两种坡地桔园3个深度的土壤水分含量均显著高于灌木林地相同深度的土壤水分。

After a significant rain event, the changes of the sills and ranges with depth became more complicated.

土壤水分的空间结构特征及其季节变化能从土地利用、地形、降雨量和土壤物理性质等因子在不同季节影响土壤水分的相对作用大小得到解释。

The quadrats of the shrub layer and herbage layer were both coordinated into four ecological types in the space of the DCA ordination. The foremost environmental factors in the DCA ordination of shrub layer is illumination and moisture, while for the herbage layer it is moisture.

DCA排序将不同林分下的灌木层和草本层都分为了4个生态类型，其中，灌木层生态类型的区分环境因子是光照和水分，而草本层生态类型的区分环境因子则是水分。

In arid regions, moisture supply is the main factor to control plant growing and survival, and the available moisture of plant shows extreme variability.

在干旱地区，水分供应是控制植物生长和生存的主要因素，植被可获得的水分具有极大的变化性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
