| 摘 要： | 为探索桐花树的淡水化人工培育技术以及筛选适宜的基质,以塘泥、黄心土、河沙和椰糠为试验材料,通过不同的配比组合成10种混配基质,并进行育苗试验,对桐花树的成苗率以及生长情况进行研究。结果发现,不同的混配基质对桐花树的成苗率、苗高、地径、根系生长、鲜重和干重等指标有明显的影响,其中以基质F（30%塘泥+50%黄心土+10%河沙+10%椰糠）综合得分最高,其平均苗高、地径、主根长、一级侧根数、全株生物量、成苗率分别比综合得分最低的基质高24.3%、11.1%、6.3%、6.5%、37.5%、2.0%。

| Abstract: | To explore the artificial cultivation technology of Aegiceras corniculatum in freshwater and to select suitable substrates for seedling culture, using pond mud, yellow soil, river sand and coconut bran as experimental materials, 10 kinds of mixed substrates were combined by different ratios, and the seedling culture was carried out. The results showed that different mixed substrates had obvious effects on seedling rate, seedling height, ground diameter, root growth, fresh weight and dry weight. Among them, the total score of substrate F (30% pond mud+ 50% yellow soil+ 10% river sand+ 10% coconut bran) was the highest. Cultured by this substrate, the average seedling height, ground diameter, main root length, number of the first-order lateral roots, whole plant biomass, and seedling rate of Aegiceras corniculatum was higher than those of the mixed substrate with the lowest score by 24.3%, 11.1%, 6.3%, 6.5%, 37.5%, and 2.0%, respectively. |
