团聚体 aggregate(567) aggregates(579)   aggregate     Soil waterstable aggregate contents and chemical properties of bamboo(Phyllostachys heterocycla) and broadleaved mixed forest stands were studied in Jiangxi province. Researched stands can be divided into Type A(bamboo stands),Type B(5%～15% broadleaf trees),Type C(15%～25% broadleaf trees),Type D(25%～35% broadleaf trees) and Type E(35%～45% broadleaf trees).     选取代表性竹阔混交林,根据阔叶树所占比例分成5种类型,即类型A(毛竹纯林)、类型B(阔叶树比例5%-15%)、类型C(阔叶树比例占15%-25%)、类型D(阔叶树比例占25%-35%)、类型E(阔叶树比例占35%-45%),分别测定林分土壤水稳性团聚体及化学性质。 短句来源     The results revealed that Type A had the lowest soil waterstable aggregate content,but highest soil structure destroy rate(average 37.27%),Type C had the lowest soil structure destroy rate(average 12.33%).     结果表明:A类型林地土壤大于0.25 mm水稳性团聚体数量最少,土壤结构破坏率最高,平均达37.27%,类型C的土壤破坏率最低,平均为12.33%; 短句来源     Mass of >0.25 mm water-stable aggregate is 23.8%-45.4%. Percentage of aggregate destruction(PAD) ranges from 52.4% to 66.8%,showing a poor aggregate stability. Ari-Sandic Primosols have the highest PAD.     >0.25mm的水稳性团聚体变动在23.8%～45.4%,团聚体破坏率(PAD)为52.4%～66.8%,团聚体组成和特征有利于抵抗土壤风蚀,但稳定性差,灌溉后易于分散、沉实板结、通透性差。 短句来源     Advance in Soil Aggregate Study     土壤团聚体研究进展 短句来源     Stable mechanisms of soil aggregate and effects of human activities.     土壤团聚体的稳定机制及人类活动的影响 短句来源 更多          aggregates     Soil bulk density,soil organic matter content,the >0.25 mm water stable aggregates and soil porosity are the main causes for the increased infiltration rate.     这主要与流域实施水土保持综合治理后土壤容重、有机质、>0.25 mm水稳性团聚体含量、孔隙度等影响土壤入渗的因素发生了明显改变有关,梯田等工程措施对土壤稳渗速率的改善作用不明显。 短句来源     POC was found to accumulate in water-stable aggregates larger than 2mm in size and to decrease sharply with the decreasing size.     >2mm水稳性大团聚体中的POC对施肥的响应较为敏感,以化肥与秸秆配施下该粒径水稳性团聚体中POC的积累效果最为明显。 短句来源     Furthermore,POC in >2mm water-stable aggregates was significantly higher under chemical fertilization plus straw return,while POC in those of 2-0.25mm and 0.25-0.053mm in size slightly higher under chemical fertilization plus pig manure,indicating a higher sensitivity of POC in larger aggregates to fertilization practices.     而化肥与猪粪配施则显著增加了2~0.25mm和0.25~0.053mm水稳性团聚体中的POC含量。 短句来源     Regression coefficients showed a possible source of POC in water-stable aggregates from increased crop biomass in topsoil(0-5cm) and organic matter applied in sub-surface layer(5-15cm).     土壤不同层次水稳性团聚体中POC的来源不同,在0~5 cm表层可能主要来源于作物根茬生物量,而在5~15 cm土层则可能跟施入的外源有机物有关。 短句来源     The percentage of >0.25 mm dry aggregates ranges from 65.2% in Ari-Sandic Primosols to 94.6% in Ustic Cambosols,while large dry aggregates(>5 mm) are dominant in all soils. Mean weightdiameter of dry aggregates(DMWD) ranges from 3.2 mm to5.5 mm.     不同土类>0.25mm的干团聚体平均变动在65.2%～94.6%,干团聚体组成以>5mm的大块状团聚体(土块)为主,平均重量粒径(DMWD)变动在3.2～5.5mm; 短句来源 更多          “团聚体”译为未确定词的双语例句     COMPARED STUDY ON SOIL PARTICLE CONSTITUENT AND MICROAGGREGATE OF ALBISOL, BLACK SOIL AND MEADOW SOIL     白浆土、黑土、草甸土土壤颗粒组成及微团聚体比较研究 短句来源     Application of Path Analysis in Study of Soid Microaggregate     通径分析在土壤微团聚体研究中的应用 短句来源     Vegetation Restoration and Improvement Process of Soil Anti-scourability in Loess Plateau──Ⅲ.
