- Abstract:
-
To analyze the effects of aerial seeding Pinus massoniana stands understory vegetation in south of Jiangxi Province on soil quality, 16 indices of topsoil (0—10 cm) physical and chemical properties of three types of understory vegetation (> 70%, 30%~70%, < 30%) were studied. Soil bulk density, field water holding capacity, soil organic matter, available phosphorus and pH value were selected as soil quality indicators. The soil quality levels of different understory vegetation were evaluated by the soil physical and chemical comprehensive index. The results showed that different understory vegetation displayed significant difference in the soil bulk density, soil water content, saturated moisture capacity, capillary water holding capacity, field water holding capacity, capillary porosity, total porosity and pH value (P < 0.05), and no significant difference was found with respect to the non-capillary porosity, soil organic matter, total nitrogen, total phosphorus, total potassium, available nitrogen and available phosphorus and available potassium (P > 0.05). The different understory vegetation displayed significant difference in the soil physical and chemical comprehensive indexes (P < 0.01). The soil quality was improved with the increase of understory vegetation.
