比较了不同调控措施对岷江上游辽东栎萌生灌丛生长与结实的影响.结果表明,人为调控对辽东栎萌生灌丛本生长阶段的高生长与有性繁殖有着显著影响.各调控措施对辽东栎灌丛萌生株的基径增长未产生明显影响;保留2支和3支萌生株的丛高生长优势明显.调控丛的新生枝数量、总长度、总生物量较未调控前有较大增加,保留2支萌生株的丛类型增加得尤为显著;叶片数量、叶片总生物量与未调控前相比增加明显,叶片面积按保留萌生株数量由多到少逐渐变小.调控后,每丛保留3支萌生株的丛产生的种子最多,但自然状态丛种子单粒重最大.
The effects of different control measures on the growth and fruiting of Quercus liaotungensis in the upper reaches of the Minjiang River were compared.The results showed that anthropogenic regulation had a significant effect on the growth and sexual reproduction of Quercus liaotungensis in the growth phase.The control measures of Quercus liaotungensis The basic growth of shrubs did not have a significant effect on the growth of shrubs, while the growth of 2 and 3 sprouts retained obvious superiority. The number of new branches, total length and total biomass of control shrubs increased greatly compared with that before unregulated, The plexus types of two sprouting strains increased more obviously, and the number of leaves and the total biomass of leaves increased obviously compared with that before non-regulation, and the number of leaf area decreased gradually from more to less. The clusters of three adventitious plants produced the most seeds, but the seeds of the highest density were found in the natural state.
