- 摘要:
- 培地茅在台湾为新兴的水土保持植物，本研究室自1997年起积极进行引种及观察研究的工作，先后引进的种原包括野生型种原15种与栽培型种原22种。经现地试验结果发现野生型培地茅可正常生育并产生种子，其产生的种子数量庞大且有效，极具有转变为杂草的可能性，应严格限制在台湾的应用，以免破坏台湾的生物多样性；栽培型培地茅，则可在台湾海拔1000m以下地区正常生长，2000m以上地区除非有足够日照与适当的种植期配合，否则不易成长。海拔1000～2000m的地区，原则上可以利用，但是如果日照明显不足，其生长将明显变缓。在滨海盐分地及泥岩地区等特殊恶劣的立地环境下，培地茅可正常生育成长。
- Abstract:
- Vetiver (Vetiveriz zizanioides) is a newly introduced giant grass for erosion control.The introduction of germplasm and study of vetiver were initiated since 1997.There are 15 wild seedy vetiver germplasm and 22 cultivated vetiver clones been introduced into Taiwan up to year 2001.The field study showed that the seedy vetiver can grow and produce seed without limitation in Taiwan, the amount of the seed is enormous and in good quality.Thus, the application of seedy vetiver must be prohibited in the perspective of its weedy potential.According the field study throughout the island, the cultivated vetiver can adapt well under the altitude of 1000 m, while over 2000 m the vetiver will grow well only with the good sunlight and proper planting date.The region between 1000 and 2000 m can grow vetiver well unless the severely shaded condition is encountered then the growth might be retarded.In the coastal area where the winter erosion prevalent, vetiver can adapt and show good growth.In the mudstone area, where post the greatest challenge to plant, vetiver can thrive as well.
