摘　　要：云南省热区是我国甘蔗的主产区之一,存在大量的甘蔗渣,为寻求其无害化、资源化高效利用,采用不同堆肥方式及不同物料配比等因素设计基质配方,开展了适合云南热区速生阔叶树种团花育苗基质的试验研究。结果表明,甘蔗渣堆肥化处理用作育苗基质,甘蔗渣的配比高达90%,基质中养分如速效磷、速效钾、交换性钙的含量均能满足团花苗木营养需求。在甘蔗渣堆肥化处理过程中,C/N呈下降趋势,基质中总N含量有明显的下降阶段,而其他养分速效磷、速效钾、交换性钙含量呈增加趋势。在基质育苗试验中,试验中期时不同基质对团花苗高、地径、根幅、主根长、侧根数、地上部干物质积累、地下部干物质积累的影响不显著。试验末期,不同基质对团花的苗高、根幅的影响显著,对地径、侧根数的影响达到极显著水平。13#基质是培育热区珍贵速生阔叶树种团花的理想基质,其次是6#基质。Sugar cane bagasse is disused in most of sugar factories. It will be a good way if it is applied in aspect of nursing substrate. The ex- periment was carried out to select the most suitable nursing substrate forAnthocephalus chinensis according to advanced substrate composting technology of Fenland in different composting mode and different ratio of material. The result obtained by analysing the characteristics of C/N of different prescription of composted sugar cane bagasse and variation of physical and chemical properties according to the standard all of the world. The result showed that the sugar cane bassage was about 90% in the all material in the suitable nursing substrate for Anthocephalus chinensis. All of the substrates had enough nutrients for seedling. The value of C/N tended to decrease, and total nitrogen（TN ）decreased distinctly during the composting. The contents of nutrient tended to increase such as phosphorus, potassium, exchangable calcium. The effect of different sabstrates on height of seedling, basal diameter, number of lateral root of seedling, dry weight of shoot, dry weight of root was not dis- tinctive in the middle of experiment. The height of seedling, root width had a distinctive difference in the different substrates by the end of experiment. Moreover the basal diameter, number of lateral root got to be difference distinctively by the end of experiment. 13# and 6# substrates could increase markedly dry weight of shoot and root, which could promote the nutrient absorb. 13# substrate was the best substrate for Anthocephalus chinensis, in the tropical region of Yunnan in the condition of the experiment. 6# substrate was the next.
