【摘要】：采用土壤盆栽試驗(yàn),研究了2種土壤調(diào)控劑(A:主要成分為硫磺;B:主要成分為風(fēng)化煤硝基腐殖酸)對高累積鎘油菜品種對污染土壤中鎘的植物提取效率。高用量的風(fēng)化煤硝基腐殖酸顯著降低了土壤的pH值,比對照處理降低了0.21~0.26個pH單位,相應(yīng)的油菜地上部鎘含量增加了20.4%~33.7%。土壤調(diào)控劑A和B對第一茬油菜收獲后土壤鎘的提取效率為0.9%~1.1%,比對照高10.5%~31.4%;A和B對第二茬油菜收獲后的土壤鎘的提取效率為8.1%~10.2%,比對照分別高4.9%~32.6%。高用量的硫肥和風(fēng)化煤硝基腐殖酸顯著提高了兩茬油菜對土壤中鎘的提取效率。
[Abstract]:A pot experiment was conducted to study the extraction efficiency of two kinds of soil regulators: sulfur B and weathered coal nitro humic acid on high accumulation of cadmium in rapeseed (Brassica napus L.). The soil pH value was significantly decreased by nitrohumic acid with high amount of weathered coal, 0.21 ~ 0.26 pH units lower than that of the control, and the cadmium content in the upper part of rape field was increased by 20.4% ~ 33.7%. The extraction efficiency of soil regulators A and B for soil cadmium in the first rape harvest was 0.9 and 1.1, which was higher than that of the control. The extraction efficiency of cadmium in the second rape harvest was 8.1% and 10.2% higher than that of the control, 4.9% and 32.6% higher than that of the control, respectively. High sulfur fertilizer and weathered coal nitrohumic acid significantly improved the extraction efficiency of cadmium from soil by two crops of rape.
