In order to study the effect of different application modes of phosphorus-solubilizing bacterial fertilizer (PSB fertilizer) on seedling phosphorus nutrition of Pinus massoniana, a pot inoculation experiment with local and evenly application of PSB fertilizer was set up. We studied the responses of P uptake and root growth of different P. massoniana families under different PSB fertilizer treatments through using WinRHIZO Pro STD1600+ root image analysis software and Molybdenum antimony colorimetric method. The results were as follows: (1)Inoculating PSB fertilizer had a significant effect on growth of P. massoniana seedlings. The main growth indexes, such as seedling height, ground diameter, root dry matter weight, root/shoot and whole plant dry matter weight, significantly increased under local treatment. (2)Local treatment significantly increased the root length, root surface area, root volume and root tip number of seedlings. The root length of 0 |
