  bulk density
The influence of woodland soil bulk density on the growth and distribution of fine root system of main planting tree species in the Weibei Loess Plateau was investigated by means of pot culture and field survey.
      
Results indicated that in the woodland of Pinus tabulaeformis, soil bulk density increased with the depth at different sites, while in the woodland of Robinia pseudoacacia, soil bulk density was higher than that in P.
      
Further analysis implied that there existed negative correlations between soil bulk density and fine root length in the woodland of P.
      
Bulk density of pot culture media had clear effects on the growth and development of P.
      
The porosity and percentage of tiny sand (diameter 0.05-0.1 mm) and clay particle (diameter >amp;lt; 0.05 mm) increased, bulk density in surface soil decreased, and saturated water-holding capacity improved.
