Abstract


In this experiment the litters of each five species of neadle-leaf trees and broad-leaf trees were laid on each pot soils, which had same soil conditions, is the green house and the soil fertility of each pots were determined after four years.
Chemical properties among each pot soils under litters of needle-leaf trees showed remarkable different values in the pH, base exchange capacity, total exchangeable base, base saturation, organic matter, available phosphorus, exchangeable potassium and calcuim, and that of broad-leaf trees showed respectively significant difference.
The content of chemical compenents, such as total exchangeable base, organic matter, total nitrogen, available phosphorus and exchangeable potassium, between pot soils under litters of the needle-leaf trees and the broad-leaf trees were significant at the 0.01 and 0.05 levels of the statistical probability.
The fertility of soil under the influence of decayed fallen leaves is the highest value in the pots of broad-leaves and next to the pots of needle-leaves and the control pots the lowest.
The pH value of the soil with various kinds of fallen leaves showed little difference among themselves, but it especially approached in the broad leaves plots gradually to neutral and the non-treated plot showed acidity.
Lsepedeza bicolar and Castanea crenata are supposed to contribute to the fertility of soil.
Pinus rigida showed excellent exchanged properties of soil.
The leaves of Robinia paseudoacacia and Pinus koraiensis did not contribute much to the promotion of fertility of soil.
