Abstract:
      With simulating of indoor bonsai test,this study investigated soil phosphorus leaching in different measure and ways with the plant growing.The result indicator that: ① the concentration of TP will increase while the phosphorus application increases,the proportion of MRP to TP will increase,the proportion of DOP to TP will decrease;② in different application of phosphorus fertilizer,the character of phosphorus leaching is also different,the concentrate fertilization can induce phosphorus leaching,while mixed the fertilizer with soil will increase the quantity of phosphorus leaching,especially dissolved phosphorus.③ the time of phosphorus leaching also effect the leaching,PP is the first leaching from the soil,the second is DOP,the mostly leaching from soil is MRP.④ DOP can leaching easily,while the content of phosphorus in soil is low,while the content of phosphorus in soil is high MRP is the mostly form of leaching.
