1) yield of root
根收量
2) specific arsenic uptake
单位根干重砷吸收量
3) root biomass
根量
1.
There is about 85 percent of root biomass which distributes between 0-60 cm in the Yellow River bank protection forest.
结果表明:护岸林约有85%的根量分布在0~60 cm的范围内,是无林地即芦苇地根量的2~3倍;护岸林林地0~60cm范围内的土壤密度远远小于芦苇地的土壤密度,土壤饱和导水率较对照区有所提高;林地根量的增加,使土壤变的更加疏松、透气、透水,降低了土壤pH值,增加了土壤养分的来源,提高了土壤有机质和多种营养元素的含量,增强了土壤抵抗水土流失的能力。
