| 1. | Field capacity is a property of a unit volume of soil . 野外容水率是单位土体的一种特性。 |
| 2. | 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。 |
| 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. | Water content at field capacity is usually expressed as a percentage of the weight or volume of oven - dry soil 土壤含水量一般用干土壤的重量或体积百分比来表示,它受土壤质地的影响。 |
| 7. | 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 。 |
| 8. | 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。 |
| 9. | 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。 |
| 10. | The coefficient of variation of saturated water content decreased with the depth of profile . the coefficient of variation of bulk density and field capacity fluctuate with depth of soil 饱和含水量的变异系数都随深度的增加逐渐降低,含水量、容重和田闷持水量的变异系数随深度的呈波动变化。 |
