Abstract
An experiment of using humic acid and its series of products was carried out to the main planting species of north-east of China, such as Pinus koraiensis,Pinus sylvestris var. mongolica, Larix gmelinii, Fraxinus mandshurica. The results show that using the compound fertilizer of humic acid could gain remarkable success for the growth of Pinus koraiensis, Pinus sylvestris var. mongolica, Fraxinus mandshurica, but it was not suitable to Larix gmenlinii.
