摘要
通过对互花米草切割试验,以及在互花米草切割迹地上进行红树恢复试验研究,结果表明:切割对互花米草的萌生株数影响不明显;腋芽数随活根生物量的增加而增加;在互花米草迹地立地条件下造林,1年生木榄裸根苗比1年生的秋茄、桐花树裸根苗更适合;秋茄1年生裸根苗造林最适密度为100 cm×100 cm;秋茄胚轴造林最佳密度为50 cm×50 cm,其次为75 cm×75 cm。
Restoration experiments of mangroves in Spartina alterniflora cutting area and cutting trial of Spartina alterniflora were conducted. The results show that cutting is not effective to the resprouts number of Spartina alterniflora , and the axillary buds number increases with living roots biomass addition. Restoration effects of mangroves in Spartina alterniflora cutting areca were analyzed. The results show that bare-root seedlings of 1-year-old Bruguiera gyrnnorrhiza grow better than 1-year-old bare-root seedlings of Kandelia candel and Aeglceras corniculatum in these sites. The optimal planting density of bare-root seedlings of Kandelia candel is 100 cm × 100 cm. The optimal hypocotyis planting density of Kandelia candel is 50 cm × 50 cm and then 75 cm × 75 cm.
