摘　　要：2016~2017年,在西双版纳普文试验林场以印度紫檀为供试树种,采用随机区组试验设计方法,进行羊粪、蔗渣、复合肥和赤红壤心土配比对印度紫檀容器苗生长差异的研究。结果表明:基质中羊粪、蔗渣的质量占比≥30%,基质中的赤红壤心土则占比少,其粘合性和持水性差,影响到容器苗的生长。羊粪、蔗渣与赤红壤心土质量比15%∶84.5%+0.5%的复合肥配成的基质,疏松性、通气性、持水性和粘合性好,肥效期长,营养均衡,对印度紫檀苗木生长的影响较好,14个月龄苗高为70.71cm,为对照的129.98%,地径为6.20mm,为对照的128.36%。该基质配方在印度紫檀容器苗培育过程中不需要进行追肥即可达到苗木出圃的质量要求,对工厂化育苗具有指导意义和实际应用价值。In the Puwen Experimental Forest Farm in Xishuangbanna,the growth difference of container seedlings of Pterocarpus indicus under different proportions of several substrates including sheep manure,bagasse,compound fertilizer and red soil was studied by random district group experiment design method from 2016 to 2017.The results showed that the mass proportion of sheep manure and bagasse in the substrate would affected the growth of container seedlings because of its poor adhesion and water holding capacity when it was more than 30%,while the proportion of red soil in the substrate was less.The substrate composed of 15%manure and bagasse:84.5%red soil:0.5%compound fertilizer had good porosity,aeration,water holding capacity and adhesion,long fertilizer efficiency period and balanced nutrition,which also had a good effect on the growth of Pterocarpus indicus seedlings.The height of 14 month old seedlings was 70.71cm,which was 129.98%of the control,and the ground diameter was 6.20mm,which was 128.36%of the control.The substrate formulation could meet the quality requirements of seedling out of nursery without topdressing in the process of container seedling cultivation of Pterocarpus indicus,which had guiding significance and practical application value for industrialized seedling cultivation.
