黄壤

Basically red yellow podzolic soils are rich in iron and soil submergence easily promote iron toxicity in lowland rice.

一般而言，灰化红黄壤中铁含量较高，淹水条件很易促发低地稻田铁的毒害。

Result shows that the weathering rates were very low (usually lower than 1.0 keq × ha-1× a-1) for allite (including red earth, lateritic red earth, red earth, yellow earth, and yellow-brown earth) in south China and silalsol (consisting of dark brown forest soil, black soil, and podzolic soil) in northeast China, but very high for xerosol and alpine soil in northwest China.

总的说来，中国南方富铝土区域（包括砖红壤带、赤红壤带、红壤黄壤带和黄棕壤带）以及东北的硅铝土区域（包括暗棕壤黑土带和漂灰土带）的土壤风化速率较低（通常低于1.0 keq × ha-1× a-1），而西北地区干旱土和高山土的风化速率则较高。

This research was based on mechanism that organic material has reconditions action on soil pollution. We chose yellow soil and calcareous soil in Guizhou province, peat coal and gentle breeze coal were added into simulated high fluorine polluted soil to study the effect of organic material on soil soluble fluorine content using the qualified design.

试验选用典型贵州黄壤和石灰土，运用有机质进行土壤污染修复的机理，通过向模拟高氟污染土壤中添加有机物料泥炭和风化煤，采用两因素最优设计，研究两种有机物料对土壤中水溶性氟含量的影响。

This paper presents charge characteristics of some red and yellow soils in Zhejiang province.

本文对浙江省红壤和黄壤的电荷特性作了初步研究。

This indicates that these HA have similar compositions, but different structures and properties.Results from analysing E465/E665 are the same as those obtained by analysing molecule structure using colour index coefficientΔ~ K.Compassion study of HA in NaOH and NaHCO_3 solutions show that the absorption peaks shift towards the direction of longer wavelength.

这几个吸收带的变化证明了以紫色潮土HA、石灰性黄壤HA、中性紫色HA、酸性紫色HA、腐殖土HA为序的腐殖酸的芳构化度降低、缩合程度下降的观象，说明腐殖土HA其分子在苯环C骨架的聚合程度、芳构化度和分子复杂程度等上均最小，与紫外光谱分析结果一致。

In a word, heavenly bamboo grew host in black limestone soil but worst in yellow soil.

各项测定指标的总体情况是黄壤＜紫色土＜黑色石灰土。

The results showed that these two rinds of carbon pools in the red and yellow soils of Zhejiang province varied greatly and were affected by land use.

结果表明，浙江省红壤和黄壤中这两类碳库有很大的变化，并与土地利用方式存在联系。

COMPARISON OF CLAY MINERAL IN TWO PAIRS OF YELLOW EARTHS AND RED EARTHS IN GUANGDONG PROVINCE

广东两对黄壤和红壤的粘粒矿物比较

The results are:(1) The higher of altitude,the less of soil acidity in soil C horizon at Dinghushan;(2) There are more NH4-N,total K,available K, exchangeable K,exchangeable Na,exchangeable Mg and the content of exchangeable cations in lateritic red soil at low altitude than those in yellow soil at high altitude;(3) With increasing altitude,the contents of sio2 and Mn decrease,and the concentrations of this two minerals in lateritic red soil are higher than those in yellow soil.

结果为：（1）鼎湖山土壤剖面C层随着海拔梯度的上升，土壤酸度降低。（2）鼎湖山位于海拔低的赤红壤的NH4-N，全钾，速效钾，交换性Na，交换性钾，交换性Mg和阳离子含量比位于海拔高的黄壤的对应养分含量要高。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
