摘　　要：以檀香不同伴生植物为研究对象,对其土壤主要理化性质进行测定,并采用灰色关联分析方法对其土壤肥力进行综合评价。结果表明:6种植物的土壤均为酸性;不同伴生植物的土壤有效Ca和有效Mg含量为极度缺乏;有机质土和碱解N含量属于中度偏低水平;有效Zn和有效Cu(除假蒿和柱花草为丰富水平)含量处于中度水平;各种伴生植物的土壤有效P和速效K含量整体处于丰富水平;土壤有效Mn(除洋金凤为中度水平)含量比较丰富;所有伴生植物中土壤有效Fe含量为极度丰富状态。综合土壤肥力评价结果为:假蒿>柱花草>山毛豆>洋金凤>降香黄檀>白木香,土壤肥力极差的的有2种伴生植物、差的有2种伴生植物、良好的有1种伴生植物、最优的有1种伴生植物,假蒿对于檀香生长的土壤肥力影响最好。Taking the different companion plants of Santalum as the research object,the main pHysical and chemical properties of the soil were determined,and the soil fertility was evaluated comprehensively by the method of gray relational analysis.The results showed that the soil of all six plants was acidic and the contents of available Ca and available Mg in soil were extremely low.The contents of soil organic matter and alkali hydrolyzate were moderately low.The available Zn and available Cu Artemisia ordosica and Stylosanthes graminearum)were moderate;however,the contents of available P and available K in all the companion plants were rich at all,and the contents of soil available Mn(except for Caesalpinia pulcherrima)were relatively abundant.However,The soil available Fe content in all accompanying plants is extremely rich.The evaluation results of comprehensive soil fertility were Kuhnia rosmarnifolia Vent.>Stylosanthes>TepHrosia candida>Caesalpinia pulcherrima>Dalbergia odorifera>Aquilaria sinensis,two kinds of concomitant plants with extremely poor soil fertility and two kinds of poor plants with good 1 kinds of accompanying plants,the best of a kind of accompanying plants,Kuhnia rosmarnifolia Vent.for the growth of Santalum soil fertility done well.
