摘要
通过模拟野外条件下落叶松根系增加分泌的草酸和柠檬酸数量,向落叶松苗木外源添加系列浓度有机酸溶液,研究了不同浓度草酸和柠檬酸对暗棕壤中Fe活性及落叶松幼苗吸收运输铁的影响。
According to the simulation of oxalate and citric acid quantity excretived by Larch root in field condition, organic acid solution with series consistence were added to Larch seedling to study the effect of oxalate and citric acid with different consistence on ferrum activation in dark brown earth and larch seedling ferrum absorbing and transporting.
