杨树人工林营养及施肥研究进展

Advances in the Study of Fertilization on Poplar Plantation

本文对杨树人工林的土壤养分供应能力、杨树对养分的需求规律、树体的营养诊断、肥料的施用时期、方法、种类及用量等进行了简要探讨 ,建议在我国加强杨树养分需求规律研究 ,尽快建立杨树植物营养诊断标准体系 ,构建基于 3S技术的杨树人工林营养管理系统 ,加强长期种植杨树人工林对土壤属性、环境等方面影响的研究。

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.
