摘要
对野葛 ( Pueraria lobata)的吸尘能力、茎抗力强度及繁殖能力进行了研究 ,结果表明 :野葛吸尘能力为2 .3 96g/50 g鲜叶 ,为对照植物冬青叶的 6.75倍、牡荆叶的 2 .62倍 ;茎节间抗力为 2 4 50 0 N/m2 ,节上抗力为980 0 N/m2 ,加上根系的固土能力 ,其抗滑坡能力可达 3 92 0 0 N/m2 ;其野生繁殖能力也很强 ,且生长迅速 .野葛可以作为净化空气、保持水土和抗滑坡的优良植物 ,并有较高的经济价值和药用价值 .
This paper deals with the study on the dust absorbing ability,stem′s resistance and reproduction capacity of Pueraria lobata. Results showed that the dust absorbing ability of leaves of Pueraria lobata is 2.396 g /50 g fresh leaves,6.75 times as much as that of Ilex chinesis ,2.62 times as much as that of Vitex negunto var. cannabifolia ;the resistance of stems is 24 500 N/m\+2,the resistance of nodes is 9 800 N/m\+2,add the force of roots which fix soil,the whole resistance which resist landslide will be 39 200 N/m\+2,the reproduction capacity is very strong and its growth is very fast.So it can be a good plant for purifing air ,conserving water and soil and resisting landslide,and has higher economic value and medical value.
