异形玉叶金花实生苗移植栽培生长节律研究

Study on the Growth Rhythm of Transplanted Seedlings of Mussaeda anomala

[目的]研究异形玉叶金花实生苗移栽生长节律。[方法]对异形玉叶金花1年生实生苗进行移栽试验,进行为期1年的生长节律观测及病虫害观察研究。[结果]异形玉叶金花移栽成活率高达100%,移植1年苗高有2次生长高峰,平均苗高68.20 cm,平均苗高生长量54.28 cm;地径生长有3次生长高峰,平均地径0.642 cm,地径年生长量为0.409 cm;虫害主要为食叶害虫,分别为污灯蛾、金毛虫、鬼脸天蛾3种。[结论]该研究可为异形玉叶金花人工促繁和保护提供科学依据。

[ Objective ] To study the growth rhythm of transplanted seedlings of Mussaeda anomala. [ Method ] One-year old seedlings of M. anomala were transplanted, the growth rhythm, plant diseases and insect pests were observed for one year. [ Result ] M. anomala transplanting survival rate reached 100%. There were 2 growth peaks in the height growth of transplanted seedlings for 1 year, the average seedling heigbt was 68.20 cm, and the annual increment was 54.28 cm ; There were 3 peaks in ground diameter growth, the average ground diameter was 0.642 cm, the annual increment was 0. 409 cm; Three kinds of defoliator were found including Spilarctia lutea, Prothesiasimiiesxanthocampa, Acherontia lachesis. [ Conclusion] The study can provide scientific basis for artificial promoting propagation and protection of M. anomala.
