鼎湖山金线兰人工栽培技术研究

目的]对鼎湖山金线兰的人工栽培技术进行研究。方法]以组培幼苗为材料,比较自然栽种条件下5种基质处理对植株生长的影响,研究鼎湖山金线兰人工种植的适生条件。结果]泥炭土-珍珠岩(4∶1,V/V)或泥炭土-沙子-木屑(3∶1∶1,V/V/V)混合基质适宜于金线兰的生长,幼苗成活率达到97.6%～94.3%,植株高度、单株叶片数和叶质量状况良好。结合试验地小环境自然气候变化情况,初步得出鼎湖山金线兰栽培适温为23～28℃,相对湿度在90%左右,适生pH约为4.75,栽培时设置遮阳网,基质不宜过湿。结论]该试验对鼎湖山金线兰的人工栽培技术进行研究,为鼎湖山金线兰的进一步开发利用提供了依据。

Preliminary Report on Artificial Cultivation Techniques of Anoectochilus roxburghii on Dinghushan Mountain

Objective] To study the artificial cultivation techniques of Anoectochilus roxburghii on Dinghu Mountain.Method] With the tissue culture seedlings as materials,the effects of 5 kinds of matrixes on the plant growth under natural conditions were compared to obtain the optimal conditions.Result] The results showed that the mixed matrix ＂peat soil∶pearlite=4∶1（V/V）＂ or ＂peat soil∶sand∶sawdust=3∶1∶1（V/V/V）＂ was suitable to growth of A.roxburghii,which survival rate of seedlings reached 97.6%-94.3%,plant height and leaf number and leaf quality were in good condition.Combined with the natural climate of small environment around experimental field,the preliminary conclusions were obtained that the temperature was 23 ℃ to 28 ℃,the pH was 4.75,relative humidity was about 90% for optimal growth of A.roxburghii.Sunshade net should be set and humidity of the matrix should not be high on the cultivation.Conclusion] The study provides basis for further development and utilization of A.roxburghii from Dinghushan Mountain.
