毛管持水量 meaning in Chinese
capillary moisture capacity
Examples
- 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
连年火烧使土壤含水率、孔隙度、分散系数、毛管持水量和田间持水量升高，而使土壤饱和持水量、容重下降。 - With increase of artificial forest age , the content of soil organic matter decreased sharply . and soil physical , chemical and biological properties of forest became worsen . from soil physical properties analysis , soil silt , clay , physical clay , aggregate degree and structure coefficient in topsoil increased with increase of artificial forest age and soil sand deceased
在土壤物理性质方面，随着人工云杉林龄的增加，土壤表层粉粒、粘粒、物理性粘粒、团聚度和结构系数降低，砂粒含量增高，土壤饱和持水量、毛管持水量及总孔隙和毛管孔隙在人工云杉演替过程中表现出“ u ”型变化。 - 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
即人工云杉幼林向成熟林演替阶段，土壤饱和持水量、毛管持水量及总孔隙和毛管孔隙则减少，在40年生云杉林达最低值，之后随着云杉自疏，微生态改善，林地凋落物分解加快，土壤饱和持水量、毛管持水量及总孔隙和毛管孔有上升的趋势，毛管持水量是决定林地自然含水量的主要因子。 - At the same time , the quality of different - state water was studied . the results show : the soil bulk density of the fir wildwood heightens with the increase of soil depth , specifically 0 . 74 > 0 . 94 andl . 34g / cm3 , the saturated , canaliculus and field moisture contents decrease gradually in layer a , b and c , accordingly the soil total foveola decreases gradually , and the moisture - hold capacity of the soil lessens gradually with the increase of the soil depth ; there is small difference of the soil bulk density between layer a and b in the outer space , which are respectively 0 . 92 and 0 . 99g / cm3 , and the other laws are the same as the in ner in the main ; reverse success often occurs in the low position of the thoroughly - fell trace and plateau marsh is formed
结果表明：冷杉原始森林土壤容重随土层深度的增加而增大，分别为0 . 74 、 0 . 94 、 1 . 34g cm ~ 3 ，饱和持水量、毛管持水量、田间持水量a层、 b层、 c层逐渐减小，十壤总孔隙度也逐渐减小，土壤的持水能力随深度的增加逐渐减弱；林外空地a层、 b层十壤容重相差不人，分别为0 . 92和0 . 99g cm ~ 3 ，其它规律与林内人体相同：皆伐迹地的低洼地段容易发生逆行演替，形成高原沼泽地。
