套种绿肥是促进桉树林生长的主要方法之一,为量化林间套种不同绿肥对桉树生长的影响,在广西国有大桂山林场开展了相关试验.结果表明:套种白灰毛豆和田菁的处理能显著提高土壤中的有机质、速效氮、速效磷和速效钾含量;2种绿肥处理也能显著增加桉树的树高、胸径和蓄积量.通过熵权法基于3种评价体系进行综合评价,均表明白灰毛豆处理对桉树生长的促进效果最好,田菁处理次之,而对照组效果最差.建议在桉树林生产实践中推广林下套种白灰毛豆.
Effects on the Growth Impact of Interplanting Green Manure in Eucalyptus Forests of the State-Owned Daguishan Forest Farm in Guangxi
Interplanting green manure is one of the main methods to promote the growth of Eucalyptus forests.To quantify the impact of interplanting different green manure on Eucalyptus growth,this study conducted experi-ments on Eucalyptus forests in Daguishan State-owned Forest Farm,Guangxi.The results showed that the treat-ment of interplanting Tephrosia candida DC.and Sesbania cannabina significantly increased the content of organic matter,available nitrogen,available phosphorus,and available potassium in the soil;Two types of green manure treatments can also significantly increase the height,diameter at breast height,and volume of Eucalyptus trees.Based on the entropy weight method and three evaluation systems,a comprehensive evaluation was conducted,all of which showed that the Tephrosia candida DC.treatment had the best promoting effect on the growth of Eu-calyptus trees,followed by the field Sesbania cannabina treatment,while the control group had the worst effect.It is recommended to promote interplanting of Tephrosia candida DC.under the forest in the production practice of Eucalyptus forests.
