| 1. | Soil at field capacity has a high water potential 土壤处于田间持水量时通常有很高的水位。 |
| 2. | Field moisture capacity foeld capacity 田间持水量 |
| 3. | Field capacity field moisture capacity 田间持水量 |
| 4. | Any more water added to soil at field capacity would drain away by gravity 超过田间持水量的所有添加的水分的都会由于重力作用而流失。 |
| 5. | Field capacity the point at which the soil contains all the water it can hold by capillary and chemical attraction 田间持水量:土壤通过毛细作用和化学吸力可维持的全部水量。 |
| 6. | The threshold value of soil water contents for photosynthesis and stomatal resistance is about 14 ( 0g ) , i . e . , 60 65 of field capacity 棉花的光合速率和气孔阻力随土壤含水量变化的阈值约在14土壤含水量水平,该阈值相当于田间持水量的60 65 。 |
| 7. | In conclusion , the variable degree of the soil water properties and bulk density in different layers is water content > wilting point > field capacity > saturation > bulk density 总的来看,各水分特性在剖面各层的变异情况为:含水量>萎蔫含水量>田间持水量>饱和含水量>容重。 |
| 8. | Bulk density in 0 ~ 20cm , 20 - 40cm and field capacity in 20 ~ 40cm can be simulated with pure nugget effect model , and they are not spatially correlated in sampling scope . 4 O ~加cm 、 20一40cm土壤容重和2 } 40cm田间持水量符合纯块金效应模型,说明在采样范围内它们的空间相关性不存在。 |
| 9. | The field capacity and porosity increase gradually and bulk density decrease gradually . the significance linear regression between the field capacity and soil organic matter is discovered as well as porosity and bulk density 此外,随植被演替, 0 5cm土层田间持水量和孔隙度逐渐增加, 0 5cm土层容重逐渐降低,且均与有机质含量呈显著线性正相关。 |
| 10. | According to physiognomy , the bulk density changed as the following order : upland > hills > hillslopes > gully slopes , the saturated soil moisture arranged as : hillslopes > hills > gully slopes > upland , while field capacity and wilting moisture are as follows : gully slopes > hills > hillslopes > upland 在地貌上,土壤容重呈现出塬面梁顶沟坡梁坡,饱和含水量呈现出塬面沟坡梁顶梁坡,田间持水量和萎蔫湿度均呈现出沟坡梁顶塬面梁坡的趋势。 |
