Environmental Geochemical Characteristics of Some Elements in the Yellow Brown Soil of Middle and Lower Reaches of Yangtze River 长江中下游黄棕壤中若干元素的环境地球化学特征
The results are as follows : The TLC of soil showed that mobility of metalaxyl was hardly level in black soil, but the mobilities in sandy soil and brown soil were middle level. 结果表明,甲霜灵在黑土中属不易移动、在褐土和粉砂土中属于中等移动。
The brown clouds in the middle are a mixture of ammonia and hydrogen sulfide. 中间的褐色云是氢和硫化物的混合体。
