培养过程中，水分和温度的有利条件促进了土壤微生物的活动，加强了微生物对无机磷的固定。
In the incubation process, the advantageous moisture content and the temperature condition promoted soil microorganism's activity, and strengthened inorganic phosphorus fixation by microorganisms.
所以茶园土壤中的磷始终处于有固定又有释放，有释放又有固定的动态变化中。
So, the phosphorus in tea soil is situated in the condition of dynamic changes which include the form of fixation and release.
林木根系生长能在一定程度上降低土壤磷的固定作用，因此土壤磷的固定量和固定率从小到大依次为根际土、根区土、非根区土。
Root growth in soil can decrease phosphorus immobilization, as both the immobilization amount and its rate appear low in rhizosphere and high in unrooted bulk soil.
