Effects of Fertilization on Fine Root Morphology of Larix kaempferi
Effects of two-year fertilization on fine root morphology, such as length, diameter, specific root length and surface area, were studied in Japanese larch (Larix kaempferi) plantation. Results showed that fertilizer treatments have different effects on root length, diameter, specific root length, and surface area of fine roots of the first-order to fifth-order. N fertilization could reduce root length and surface area, but expand root diameter and specific root length. However, P fertilization could enlarge root length, while reduce root diameter, specific root length, and surface area. N+P fertilization could reduce root length and specific root length, but enlarge root diameter and surface area. However, all of the differences were not significant.
