紅砂壤
英文
arenosol-
The soils ( paleudults ) consist predominantly of light brown fine loamy sand to fine sandy loam changing with depth into a brown sandy clay loam and sandy clay with red mottles
土壤(強發育濕潤老成土)主要為淡棕色細壤質砂土到細砂質壤土,隨著深度增加,土壤變為棕色砂質粘壤土和帶有紅色斑點的砂質粘土。Some soil microbial activity parameters and heavy metals contents were analyzed by principal component method. the results showed that the critical levels of cadmium and lead in red clayed soil and red sandy soil were 15 mg. kg - 1 and 0 - 15. mg. kg - 1, 200 mg. kg - 1and 200 - 400 mg. kg - 1, respectively. soil microbial populations and functional diversities of microbial community have changed to some extent under the stress of cadmium and lead pollution
在本文中我們將供試紅壤的上述微生物活性指標和2種重金屬含量進行主成分因子分析,其結果得出,紅黃泥和紅砂泥的土壤微生物活性鎘脅迫的臨界承載量分別為15mg ? kg ~ 1和0 15 ? mg ? kg ~ 1 ;鉛脅迫的臨界承載量分別為200mg ? kg ~ ( - 1 )和200 400mg ? kg ~ ( - 1 ) 。The concentrations of copper, lead and zinc in the shoot of e. splendens were affected by chemical and physical properties, such as full contents of heavy metals in soils, soil ph and organic carbon content, etc. the shoot can accumulate copper more on the red sandy paddy soil collected from dongxiang country, jiangxi province, than on silt paddy soil from fuyang country, zhejiang province. e. splendens took up much less copper from fuyang soils, the concentrations of zinc and lead in shoot were not also quite low
在酸性紅砂土上植物對銅的吸收和富集隨土壤銅含量的增加而顯著升高;而在銅、鋅、鉛復合污染的中性泥沙土上海州香薷體內銅含量和積累量不高,處于正常植物生長范圍內,植物體內鋅、鉛含量及其積累量也不高,海州香薷對重金屬的吸收和富集能力有限。Moreover, the effect of heavy metal pollution on soil microbial indexes was significant in red sandy soils
兩種土壤比較,以上微生物活性指標對重金屬脅迫的響應程度在紅砂泥上表現更為明顯。Two incubation experiments were conducted to evaluate the effect of cadmium and lead applied singly on soil microbial activities and functional diversity of microbial community in red clayey soil and red sandy soil
以紅黃泥和紅砂泥兩個土屬作為供試紅壤,採用室內培養方法對外加鎘、鉛污染紅壤的微生物活性及群落結構進行了研究。Additionally, through the use of clustering analysis, principal factor analysis and the correlation analysis, we found that the genetic structure of natural population reawnuria soongorica was related to the ecological factors ( soil factors mainly ) of the oasis - desert transitional zone
而其它土壤生態因子則與紅砂的遺傳多樣性指數的相關性均不顯著( p 0 . 05 ) 。表明紅砂個體的分佈可能與過渡帶土壤的某些易溶性鹽分相關。As for h2 and h3 derived from quaternary deposits, the textures of soils would become heavy because of soil erosion, whereas t2 and t3 of red soil of granite became sandification
土壤侵蝕會引起土壤機械組成的改變。對于第四紀粘土發育的紅壤,土壤質地粘重,而花崗巖紅壤,侵蝕使其趨向砂質化。分享友人
