带状采伐下孕笋期土壤温湿度变化及发笋的影响因子分析
Analysis of influencing factors of soil temperature and humidity change and bamboo shoot growth under strip cutting
[目的]带状采伐被用来解决传统经营中择伐费时费力的问题,而采伐对土壤扰动较大,带状采伐后孕笋期的土壤温湿度变化规律以及其对出笋数的影响尚不明确。[方法]本文监测 3 个带状采伐样地(采伐带宽分别为 3m、8m、15m)与未采伐样地(ck)各个土层(0-10cm、10-20cm、20-30cm、30-50cm)六月至十二月的土壤温湿度变化情况,探究温湿度变化规律。在采伐样地和参考样地采集 0-10cm、10-20cm、20-30cm、30-50cm…查看全部>>
[Objective]Strip cutting is used to solve the problem of time and effort of selective cutting in traditional management.However,the change of soil temperature and humidity in the bamboo shoot stage after strip cutting and its influence on the number of bamboo shoots are still unclear.[Methods]In this paper,soil temperature and humidity changes in each soil layer(0-10cm,10-20cm,20-30cm,30-50cm)were monitored from June to December in 3 ribbon-cut plots(logging…查看全部>>
