a fine-grained fertile soil deposited by water flowing over flood plains or in river beds

so the yellow river alluvial soil expresses some engineering characteristics, such as, difficultly to be compacted and stabilized with inorganic binder, and large foundation depression.

由于以上特点，黄河沖淤积土表现出难以压实、无机结合料稳定困难，地基沉降量大等工程特点。

myricaria laxiflora, on the other hand, prefers the alluvial soil with sand and gravel in subtropics climate. the soil is of weak alkalinity, has low content of nutrient but moderate salt.

疏花水柏枝适宜于亚热带气候下弱堿性、养分含量低的沖积性砂砾质初育土，能耐一定程度的盐分。

results show that response at surface points of the alluvial soil deposit are amplified significantly for given conditions of shape, dimension and material properties of the soil and the canyon.

计算结果表明：在给定河谷形态、尺寸和材料性质条件下，沉积层表面各点的响应显着放大。

the result of pot test showed the yield of the crops increased if applying boron in 4 soils with the exception of the alluvial soil in which hwsb was higher than that in other soils.

盆栽试验结果表明，除hwsb较高的潮土外，其余4种土壤施硼均有不同程度的增产效果。盆栽试验和培养实验都证明热水不能完全提取当季施入土壤中的硼，而这些硼在后季作物生长中继续发挥效果。

alluvial soil a type of soil formed on river floodplains and deltas, where new sediment is deposited on the land during floods.

在河流漫滩和三角洲地带由洪水沖刷泥沙沉积而形成的土壤类型。

downstream water flow slow, siltation of the alluvial soil more and more, forming a great many of the delta islands.

下游水流缓慢，淤积的沖积土愈来愈多，形成一个有许多岛屿的巨大三角洲。
