Conservation of Taxus cuspidata in Northern Coastal Areas
[Objective]This study aimed to analyze the ex situ growth pattern of Taxus cuspidata in the northern coastal areas to provide support for ex situ conservation.[Method]In this study,four different site conditions were set under the coastal shelterbelt system of Yantai,and the afforestation experiment of northeast taxus native place conservation was carried out,in which the basic phenological rules,preservation rate and morphological indexes were analyzed.[Result]Seven-year-old Taxus cuspidata can blossom and bear fruit,and the average survival rate of afforestation is more than 80%,and the transition area of plain coastal defense forest is the highest,more than 94%.In terms of comprehensive seedling quality,Muping District tavern Village and Yetou Village in Laishan District have the best performance,followed by Kunyu mountain,and the coastal base forest was the worst.The high growth law of Taxus cuspidata varies significantly under different site conditions,among which the hilly area performed the best,with the annual growth of more than 10 cm,and the coastal base dry forest belt showed the worst performance,with negative growth.[Conclusion]Seven-year-old Taxus cuspidata can complete the whole plant life history in Yantai and successfully protect it locally.The adaptability is significantly different under different site conditions,and the migration effect of Taxus cuspidata in the transition area and hilly area of plain and coastal forest is better.The quality of seedlings is related with the site conditions of afforestation,and the quality of seedlings is positively correlated with soil physical and chemical properties.Taxus cuspidata to drought and waterlogging,and wind erosion in coastal zone seriously affects the growth of Taxus cuspidata.
