摘要

Using spring wheat as tested materials, by pot experiments and three fertilization modes (seed soaking mode, irrigated fertilization mode and mixed using mode), the effects of sodium humate on the wheat seedlings growth and mineral elements (Cu, Zn, Fe, Mn) absorption were studied. The results indicated that, all three modes showed obviously resistance performance to Cd stress, promoted the wheat seedlings growth and the dry matter accumulation, and the third mode had the best effects. In the background soil, sodium humate treatments could obviously inhibit the Cd elements absorption; promote the mineral elements absorption and accumulation. Along with the Cd stress degree aggravating, the inhibition effects reduced. At the same time, different fertilization modes had different effects on mineral elements absorption and accumulation. The research also puts forward that humic acid fertilizer is an ecological fertilizer and soil conditioner with alleviate heavy metals pollution and enhance plant stress resistance function.
