土壤空隙度
土壤孔隙度
土壤孔隙率
Examples
- It concluded 56 that ferrisols aggregate breakdown was caused by the pressure produced by the entrapped air in the soil porosity when fast wetting , which indicated that ferrisols erosion was most severe in the sudden heavy rain in the nature
富铁土团聚体的崩解主要是由土壤快速湿润时，挤压孔隙内的闭塞空气而产生的压力，说明富铁土土壤在突降暴雨时侵蚀最严重。 - They decrease soil bulk density , increase soil porosity and soil saturated water content . the result of straw mulch is best , plastic mulch is better . the movement of soil water in gneiss area of tai - hang mountain has following regulation
其中以秸秆覆盖的效果最好，其次为地膜覆盖；太行山片麻岩区土壤水分运动有如下规律，土壤含水量随土壤深度的增加而逐渐降低。 - ( 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
… ）实施农林复合经营和生物篱埂技术可明显的改善土壤结构，降低土壤容重，增加上壤总孔隙度和毛管孔隙度，从而提高土壤的保水持水性能。 - The result indicated that straw mulching could increase soil porosity by 2 . 88 % - 5 . 76 % , reduce soil bulk density by 1 . 86 % - 3 . 73 % and the content of soil water with straw mulching was higher than that with no straw mulching treatment ( ck1 ) at different growth stage , improve water - stable aggregate ; and increase soil organic matter , available n , available p , available k , improve soil perviousness and soil retention of water and fertilizer
研究结果表明，与对照ck1 ，相比，秸秆覆盖可使土壤总孔隙度增加2 . 88 % ~ 5 . 76 % ，土壤容重降低1 . 86 % ~ 3 . 73 % ，并且各生育期覆盖处理的土城含水量均比对照高，并且秸秆覆盖还田对促进土壤团粒结构形成具有较大作用，改善了土坡通透性和保水保肥性；同时秸秆覆盖还田使土壤有机质、全氮、速效氮、速效磷、速效钾得到明显提高，从而培肥地力。 - 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。
