摘要
为丰富福建沿海造林树种,引进台湾海岸防护林树种海檬果的种子,在惠安赤湖林场开展种子育苗和扦插繁殖试验,结果表明,海檬果种子苗的形成需要两个半月的时间,苗木在8月上旬到10月上旬高生长较快,而地径生长平缓。海檬果穗条扦插受生根剂种类和浓度、木质化程度及其在母树上部位影响,选择母树上部半木质化的穗条经过质量分数为100×10-6的吲哚丁酸或质量分数为25×10-6的萘乙酸溶液处理后扦插,穗条生根率可以得到明显提高。
The seeds of Cerbera manghas from Taiwan were introduced to Fujian ＆ experiments of seedling cuhure were carfled out in Chihu stated-owned protection forest farm in Huian county in order to rich tree species in Fujian coastal zone. Result shows that the forming of seedling of Cerbera manghasby seed breeding need two ＆ half months, height growth of seedlings from early August to early October is fast while the growth of ground diameter is slow. The rooting rate of the branch cutting of Cerbera manghas is affected by the type ＆ concentration of the growth regulators, the lignification degree of the cutting ＆ the position of the cutting in the mother tree. It can be improved obviously after using concentration of 100 ×10^-6 IBA or 25×10^-6 NAA to deal the above cutting in the mother tree.
