寄主植物生长情况及配置距离对檀香幼林生长的影响

通过在造林时混合配置8种寄主植物,研究在一年生、三年生、四年生檀香(Santalum album L.)人工林中寄主植物配置距离、植株高度、胸径、生长状况等对檀香幼树高径生长的影响。结果显示,木麻黄(Casuarina equisetifolia L.)的树高与檀香树高呈显著的负相关,飞机草(Eupatorium odoratum L.)株高与檀香株高和胸径呈极显著的负相关;在一定配置距离范围内,假蒿(Kuhnia rosmarnifolia Vent.)、山毛豆(Tephrosia candida DC.)、相思(Acacia confuse Merr.)的配置距离与檀香幼树生长呈显著的正相关;从寄主植物根系寄生的檀香吸盘发生情况来看,山毛豆是最佳寄主,木麻黄、苏木(Caesalpinia sappanL.)、麻楝(Chukrasia tabularis A.Juss)次之,假蒿吸盘多但较小;飞机草最差。整体上看,寄主植物山毛豆和降香黄檀(Dalbergia odorifera T.Chen)对檀香的生长极为有利,是较佳的寄主;假蒿、苏木、相思、木麻黄、麻楝其次,飞机草较差。

Influences of Growth and Arrangement Distance of Host Plants on the Growth of Santalum album Artificial Young Plantation

The influences of growth and arrangement of 8 host plants in mixed artificial plantation on height,diameter of Santalum album L were studied.The results were as follows,there was significant negative correlation between the height of Casuarina equisetifolia L.and the height of sandalwood,very significant negative correlation between the height of Eupatorium odoratum L.and height and DBH of sandalwood,significant positive correlations among the arrangement distance of Kuhnia rosmarnifolia Vent.,Tephrosia can...
