capillary water capacity
解釋
毛管容水量-
Field capacity the point at which the soil contains all the water it can hold by capillary and chemical attraction
田間持水量：土壤通過毛細作用和化學吸力可維持的全部水量。 -
2. the structure of purple soil is meliorated by sabaigrass. when contrast to bare land treatment and natural wild grassland treatment we knew that sabaigrass treatment and grass tree solid plating treatment reduced soil bulk density, enhanced soil capillary porosity, non - capillary porosity and porosity ratio, decreased soil sand grain content, enhanced soil clay grain and silt grain content so as to reduced the dispersal degree of soil, improved the aggregate capacity of soil, increased the amount of soil aggregate structure, meliorated the water permeability of soil, accelerated the form of good soil structure
龍須草能改善紫色土的土壤結構龍須草純種植被和林草立體種植植被能不同程度地降低土壤容重，減少土壤砂粒含量，增加土壤的毛管孔隙度、非毛管孔隙度和孔隙比，以及增加粉粒含量，從而降低土壤分散度，提高土壤團聚性，增加土壤團粒結構數量，改善土壤的透水性，促進良好土壤結構的形成，最終提高土壤的蓄水保肥性能，增強土壤的抗蝕性和抗沖性。 -
And the major results and some new viewpoints were presented as follow : 1 ) sediment content of cn tillage system in runoff process is substantially low compared to st under rainfall with high intensity, showing cn bear the efficient capacity of control soil loss. nevertheless, when soil is saturated, the runoff intensity of both tillage systems is near, implicating cn has the limited function of reducing runoff. 2 ) based on the case analysis of observed all rainfall - runoff generation processes, a ) the initiation time hysteresis of surface runoff generation is notable when rainfall fall upon the unsaturated purple soils, which is attributed to the property of rapid water sorption and much non - capillary porosity
經近幾年的觀測和理論分析，取得了以下結果和創新的認識： 1 ）在降雨強度較大的情況下，保護性耕作制? ?聚土免耕的產沙強度明顯較常規耕作制? ?順坡耕作的小，說明聚土免耕耕作制防治土壤流失是有效的；但當土壤達到飽和后，聚土免耕的徑流強度與常規耕作的差異較小，產沙強度也增大，因此，聚土免耕防治水土流失的能力是有限的。 -
( 6 ) in agroforestry and contour hedgerow treatments, soil structure and soil texture is improved with soil bulk density decreasing and soil porosity and capillary pore increasing. finally, water - holding capacity is improved. ( 7 ) soil loss in small plots of comprehensive management treatments is significantly lower than that in control
… ）實施農林復合經營和生物籬埂技術可明顯的改善土壤結構，降低土壤容重，增加上壤總孔隙度和毛管孔隙度，從而提高土壤的保水持水性能。 -
Soil saturated capacity, capillary capacity, total porosity and capillary porosity showed the trend of the " u " during the successional course of artificial forest, namely, they reduced on the early successional stages, after picea reached mature forest, soil porosity recovered slowly. the content of natural water was mainly affected by capillary porosity. from soil chemical properties analysis, the content of soil organic, humus, ha, fa and ha / fa of topsoil was more than that of bottom layer
即人工雲杉幼林向成熟林演替階段，土壤飽和持水量、毛管持水量及總孔隙和毛管孔隙則減少，在40年生雲杉林達最低值，之後隨著雲杉自疏，微生態改善，林地凋落物分解加快，土壤飽和持水量、毛管持水量及總孔隙和毛管孔有上升的趨勢，毛管持水量是決定林地自然含水量的主要因子。 -
After yearly burning, soil moisture content, porosity, separate coefficient, capillary and field moisture capacity increased, however, soil saturated water retaining capacity and unit weight decreased
連年火燒使土壤含水率、孔隙度、分散系數、毛管持水量和田間持水量升高，而使土壤飽和持水量、容重下降。
