Effects of Phosphatic Fertilizer on the Growth Dynamics of Pinus massoniana Seedling
Fertilizer was applied on one-year Pinus massoniana seedling.Three amounts of P fertilizer applications and control were designed with complete random.The status of height,diameter and root of seedling were determined at every months after fertilizer application.Results showed that the height and fine root under P fertilizer treatment was higher than that of the contrast.There was an affinity between the growth of the height and diameter and the weather.The fine root growed inconspicuously in the prior period.From Sept.the fine root showed slower growth.With the amount of P fertilization increasing,the height,root length,root surface area,root volume and biomass increased.This change was conspicuous from Aug.to Dec..With the increase of the P,the biomass increased,the fine root morrphology decreased in the Feb..The morrphology of fine root was the best under the treatment P2.
