Examples
- Microfloral activity in worm may have an important effect on soil crumb structure .
蚯蚓类中微生物群落活性对土壤团粒结构可起重要作用。 - Because these factors make change more often , soil time space variability is more bigger . the relationship of single factor between soil water infiltration capacities and certain influencing factor could be established quantitatively by means of soil water infiltration tests in indoor , there is negative correlation relation between soil water infiltration capacities and soil structure . there is negative correlation relation in high grit content and low physical clay content soil , and second - degree polynomial relation in high physical clay content junk structural soil between soil water infiltration capacities and soil moisture
由于这些因素在时刻发生变化，使得土壤的时空变异性较大，只能用室内土壤水分入渗试验来定量确定土壤水分入渗能力与某些影响因素之间的单因子相关关系，土壤水分入渗能力与土壤结构之间呈负相关关系，土壤水分入渗能力与土壤含水量之间在土壤砂粒含量高，物理性粘粒含量低的无结构土壤中呈负相关关系，在物理性粘粒含量高的团粒结构土壤中呈二次多项式关系。 - The results are summarized below : 1 ) study on soil science indicates that soil granular structure is the focus adjuster for soil fertility and it affects the space , water - grasp , aeration and anti - erosion of soil . and the percentage of aggregate is one of the key index that decides the speed and extent of soil erosion , hardening and degeneration because the soil degeneration will first lead to the disappearance of crumb - structure . so it is very important that the physical course and character of soil in different land use pattern are realized
现将主要结果摘要如下： l 、士壤学研究表明，团粒结构是土壤肥力的中心调节器，影响着土壤的空隙性、持水性、通透性和抗蚀性；任何土壤的退化首先将表现出团粒结构的消失；团聚体百分比是决定土壤侵蚀、板结等物理过程速度和幅度的关键指标之一，了解不同土地利用和土壤管理方式的物理过程和性质相当重要。 - According to climate and geography character in high - cold area , by indoor trial , the paper researches the material component impact on the physical and chemical property and presents reasonable component mixture ratio of the ecological material and analyses the aggregates , drought resistance and fertilizer effect of the material
针对川西高寒地区的气候特征、地理地质环境特点，通过室内试验的方法，研究了生态基材组分构成及其配比对生态基材物理化学性质的影响，重点分析了生态基材的团粒结构、抗旱性、肥效及其和草种藕合生长关系。 - 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。
