| Abstract: | This paper discussed the ability of nutrient supports on soil, plant nutrition diagnosis, fertilization timings, methods, varieties and rates on poplar plantation. The authors suggested that attention should be paid to establishing a nutrient diagnosis standard and making more studies on nutrient requirement characteristics of poplar, and establishing poplar forestry management system based on 3S technique in China as soon as possible. In near future, more studies on the effect of long term poplar planting on soil fertility and environment should be contacted. |
