不同施肥量对黑木相思生长特性影响研究

Study on the Effects of Different Fertilization Rates on the Growth Characteristics of Acacia nigra

本研究旨在探究不同施肥量对黑木相思的生长特性的影响。通过对黑木相思的株高、胸径、枯梢植株比例、枯梢长度等指标进行观察和测定,并采用统计分析方法,研究了施肥量与这些生长特性之间的关系。实验结果显示,施肥量对黑木相思的生长特性有着显著的影响。随着施肥量的增加,株高和胸径呈逐渐增加的趋势,枯梢植株比例和枯梢长度则呈逐渐减少的趋势。此外,不同施肥量还对黑木相思叶片的营养元素含量产生了影响。

The aim of this study is to investigate the effects of different fertilization rates on the growth characteristics of black wood acacia.By observing and measuring the plant height,diameter at breast height,proportion of dead shoot plants,and length of dead shoot of Acacia nigra,and using statistical analysis methods,the relationship between fertilization amount and these growth characteristics was studied.The experimental results showed that the amount of fertilization had a significant impact on the growth characteristics of black wood acacia.As the amount of fertilization increases,the plant height and diameter at breast height gradually increase,while the proportion of dead shoot plants and the length of dead shoot gradually decrease.In addition,different fertilization rates also had an impact on the nutrient content of black wood acacia leaves.
