"上阔下竹"模式对毛竹林林地土壤及毛竹林生长的影响
The Effect of Mountaintop Broad-leaved Trees on the Field Soil and Growth of Moso Bamboo
摘要
Abstract
Moso bamboo ( Phyllostachys edulis) is one of the most important forest resources in southern China .Intensive manage-ment is an effective way to improve the economic benefits of bamboo forest .However , with the extension the intensive operation time , the ecological negative effect is becoming more and more prominent .In order to realize the sustainable development of bamboo forest , we put forward the model of compound management .We selected a mountain with same slope and similar management in Yong 'an City Tied-ingshi Village to verify the effectiveness of the model .According to the mixed proportion , the forest is marked as type I ( mixed ratio is 32%) , type II ( mixed ratio is 28%) , type II ( mixed ratio is 25%) and type IV ( mixed ratio is 0%) .The effect of mountaintop broad-leaved trees on the field soil and growth of Moso bamboo is analyzed .Results show that there was no significant difference be-tween the 4 mixed forest types of total nitrogen , phosphorus and potassium in Moso bamboo forest (Phyllostachys edulis).The hydrolyza-ble nitrogen, available phosphorus and potassium of the broad -leaved forest at the mountain top were lower than that of the bamboo for-est at the foot of the mountain .There was no significant difference either between the 4 mixed forest types of hydrolyzable nitrogen , a-vailable phosphorus and potassium at the same slope position .When mixed ratio was 28%, the average DBH of bamboo in all parts of the mountain was the largest .Compared with other mixed forest , the average DBH could be increased by 5%~12%.关键词
