施用草甘膦对桉树人工林土壤理化性质的影响

开展化学除草与人工近自然抚育技术试验，研究不同植被控制技术对生长量、植被以及土壤的影响，为合理使用化学控制植被技术提供参考。从研究结果看，近自然抚育对保留植被和生态效益可能会好，但对桉树生长没有优势；化学除草剂对土壤理化性状的影响。

A controlled field experiment was conducted to evaluate two vegetation control technologies: chemical weed control and artificial near-natural tending. The experiment aimed to investigate the effects of different vegetation control measures on tree growth increment, vegetation communities and soil properties, so as to provide scientific references for the rational application of chemical vegetation control technologies. The results show that near-natural tending may yield better outcomes for retained vegetation and ecological benefits, but provides no advantages to the growth of Eucalyptus; the impacts of chemical herbicides on soil physical and chemical properties were also analyzed.
