通过对新河高速公路沿线乡土护坡植物调查研究,对沿线出现频度较高的护坡植物:滇桐、葛藤、黄金间碧竹进行培育和驯化。经扦插试验结果表明,滇桐在ABT浓度为100 ppm时,成活率最高为87%;葛藤在ABT浓度为50 ppm时,成活率最高为90.5%;黄金间碧竹在ABT浓度为50 ppm时,成活率最高为88.5%。且滇桐的抗旱性最强,其次为葛藤,最差的为黄金间碧竹。生长特性试验表明,3种扦插植物在2006年生苗期内和2007年边坡种植试验中,生长曲线均呈“S”形,滇桐、葛藤、黄金间碧竹的生长高峰期分别在7月、8月和9月。与苗圃内相比,边坡上种植植物的生长曲线较平缓,生长速度明显变慢,主要是边坡生长条件较差的缘故。
Through the investigation and study of native slope protection plants along the Xinhe Expressway, cultivated and domesticated Bambusa orientalis, kudzu and golden bamboos, which occur frequently along the line. The results showed that the highest survival rate was 87% when the ABT concentration was 100 ppm, the highest survival rate was 90.5% when the ABT concentration was 50 ppm and the highest when the ABT concentration was 50 ppm , The highest survival rate of 88.5%. And Diantong the strongest drought resistance, followed by kudzu, the worst for the yellow bamboo between the gold. The growth characteristics test showed that the growth curves of the three kinds of cutting plants showed “S” shape during the seedling stage in 2006 and in the slope planting experiment in 2007, and the growth curves of the four cutting plants were “S” July, August and September. Compared with the nursery, plant growth on the slopes of the slope of the growth curve is relatively slow, significantly slower growth rate, mainly because of poor slope growth conditions.
