不同施肥处理对桃容器苗生长及 SPAD 的影响.

[Objective]To understand the effect of different fertilizers and different fertilization amount on the growth and SPAD of container Prunus persica L. and provide optimal fertilization method for high quality peach plants. [Method]Thirteen different fertilization treatments were designed to study the plant height, ground diameter, crown breadth, branch numbers, the length of current-growth branches and SPAD of container Prunus persica during different periods. [Result]Compound fertilizer of balanced type was more suitable for plant growth than humate fertilizer of phosphorus and potassium type. Combination application of balanced compound fertilizer and low concentration EM bacteria was more beneficial for the growth of container Prunus persica single compound fertilizer. [Conclusion]The optimal treatment for the growth of container Prunus persica was to apply nitrogen, phosphorus and potassium balanced compound fertilizer (20 ∶ 20 ∶ 20) with 1 ∶ 1 000-1 ∶ 500 concentration and EM bacteria with 1 ∶ 200 concentration during growing period.
