摘要

2000年2、4、6月進行地被植物之調查、蒐集計有馬蹄金、黃花蜜菜、天胡荽、銅錘玉帶草等20個種類，經栽植繁殖後定植於田區，以建立種原圃。另以蛇莓、薄荷、乞食碗、雷公根等8個種類進行篩選試驗，初步結果，成活率除乞食碗之93%外，其餘7個種類均達100%，即完全成活。株高或蔓長，初次調查即種植2星期後，以薄荷之27公分及雷公根之22公分，生長為最高，而後每2星期再調查一次，結果均以黃花蜜菜之生長最為快速。生長勢之調查亦同，第一次調查以薄荷、雷公根之生長勢為最強，而後以黃花蜜菜之生長勢為最強。披覆率於種植第3星期後，仍然以黃花蜜菜及雷公根兩個種類之披覆率達到100%，而乞食碗僅為47%，生長較為遲緩。

The vegetation plants investigated and collected on February, April and June in 2000 Were Dumbell Dichondra, Chinese Wedelia, Coin Penngwont, Pratia etc. 20 kinds which were planted after propagation for setting up protoplasm nursery. The survival rate of Dumbell Dichondra, Torcke indiam strawbers, Coin Penmywort, Menthae Folium, Pratia, Asiatic centella, Chinese Wedelia was 100% but only Beggar bowl 93%. At first investigation 2 weeks after planting, Menthae and Asiatiu centella were the highest to 27 cm and 22 cm, respectively, but afterward every third week investigation, Chinese wedelca was the best and the fast growth in each time. The vegetation rate 3 weeks after planting was 100% for Chimese Wedelia and Asiatic centella, but Beggar bowl was only 47% with lag growth.
