Change of moisture retention in sandy soil after planting mixed forest of Populus spp.and Robinia pseudoacacia

Abstract

Abstract: The change of soil moisture retention after planting mixed forest of Populus spp.and Robinia pseudoacacia was studied by comparative method. The results showed that soil moisture retention, spatial distribution of soil pore, and soil water capacity were improved and increased in sandy soil after Populus spp. and Robinia pseudoacacia being planted, and the improvement in the mixed forest of Populus spp. and R. pseudoacacia was greater than that in the pure forest of Populus spp.or R. pseudoacacia.The basic reason of soil moisture retention being improved was the increment of soil organic matter,which improved soil pore condition.

Key words: Sandy soil, Populus spp., Robinia pseudoacacia, Mixed forest, Moisture retention
