laterization

Study on granular structure in laterite vn soil has already been reported in different land use pattern but it is little about soil fertility in karst environment . the better the soil structure , the higher the content of water - stable soil aggregate so there is an osculation correlation between aggregate and structure of soil 不同利用模式下紅壤團粒結構的特征研究己有報道,但關于巖溶環境中土壤變化的研究則很少。土壤團聚體與土壤的結構密切相關,團聚體含量高,則說明土壤結構好。

The authors studied the characteristics of element geochemistry , mineral assemblage and microtexture of the white reticulate clay in the quaternary laterite of the dongting basin with some experimental analysis methods , such as chemical analysis , x - ray diffraction analysis , ir and sem analysis . the genesis of the vermiculate reticulate clay and the rhizomatic reticulate clay in the quaternary laterite of the dongting basin are discussed . the formation of crannies or holes in the soil and the transference of soil elements are absolutely necessary conditions to form the white reticulate clay in laterite 在野外考察的基礎上,運用化學全量分析x射線衍射分析紅外光譜分析和掃描電鏡微形貌分析等實驗方法和手段,對洞庭盆地第四系紅土地層中網紋的元素地球化學礦物組合特征和微形貌特征進行了系統研究,對洞庭盆地紅土地層中2種主要的網紋類型蠕蟲狀網紋和根狀網紋的成因進行了探討。

The intense eluviation and weathering of soil with groundwater and run - off result in the enhancing of capacity of transference of some elements , such as si , al , fe , mn . the chemical reactions of the colloid particles in the soil water make those crannies or holes filled by some epigenetic clay minerals and quartz . then a great deal of white reticulate clay comes into being in the quaternary laterite of the dongting basin 地下水和地表水強烈的淋溶作用使土壤中硅鋁鐵錳等元素的遷移能力增強,土壤膠體粒子之間的化學反應,使得這些孔隙空間在后期逐漸被次生黏土礦物和石英所充填,最終,在洞庭盆地第四系紅土地層中形成大量的蠕蟲狀和根狀白色網紋。

During the visiting to the earth building , both foreigners and domestic travelers can feel straightforwardness , alacrity and hospitality of the hakkas who are as simple and unsophisticated as laterite 去“土樓”旅游,無論是外國人,還是國內的人都能感受到土樓客家人的粗獷豪爽,熱情好客,他們就像紅土地一般厚實、淳樸。

However for p supply , dap was found superior source and rock phosphate tended to be equally effective source of p in acid laterite soil 不過對于磷素供應來說,磷酸二銨是最好的來源,磷礦粉在酸性紅壤土上同樣有效。

Laterite a hard crust that may form on the surface of the soil in tropical regions with alternating wet and dry seasons 紅土:在熱帶地區,土壤表面由于干濕交替而行成的具有堅硬外殼的一種土壤。
