Abstract

Fine tree roots are important organs that absorb water and nutrients from the soil；their growth，death，and decomposition processes play a major role in forest ecosystem recycling. Root absorption of one factor （water or nutrients） can influence the other，and soil moisture and nutrient availability can affect fine root growth and development. Seasonal dynamics of fine root growth coincide with seasonal dynamics of soil moisture distribution. When soil moisture increases，fine root biomass also increases. Nevertheless，the effect of soil nutrients on fine root growth is complicated；for example，an increase in nutrients can produce：a） an increase or decrease in fine root biomass，b） generally an increase in root length and diameter of the lower root，and c） a decrease in specific root length. Repeated applications of water and fertilizer greatly improved fine root biomass with notable seasonal changes，such as an increase in length density of fine roots and fine root longevity more short or long temporarily. After considering growth laws and reasons for changes in fine roots for different species and different site conditions，we suggest that future research with fine roots should focus on the combined effects of water and nutrients.［Ch，56 ref.］
