Effects of Sand Burial Depth on Seedling Growth of Caragana microphylla

Abstract:

Caragana microphylla is a pioneer leguminous shrub species, and plays an important role in sand fixing and desertification control in the Horqin Sandy Land of Northern China. In this study, seedlings were buried by sand to depths of 0 (control), 1/3, 2/3, 1 and 4/3 of their mean height, and the effects of sand burial depth on seedling growth of Caragana microphylla were tested. Results show that with increasing burial depth, biomass allocation to leaves decrease, while stem biomass allocation increase, and both shoot and root growth of C. microphylla are stimulated and seedling biomass is the highest when burial depth is 2/3 of seedling height. Therefore, moderate burial could facilitate seedlings growth of C. microphylla
