摘要:

以无性系植物的生理整合作用理论为指导,通过不同密度处理系列试验、采笋与不采笋对比试验等,探讨了密度调节、轮闲制采笋与筇竹林竹笋—幼竹生长的关系。结果表明,将4~5a生老龄母竹全部砍伐的处理对子代分株密度具有显著的影响,其1a生分株数量是全部保留处理的1.92倍。轮闲制采笋的处理则有利于子代分株个体的改良,1a生分株的平均胸径和平均高度是未处理的1.5倍和1.4倍;而连年采笋的筇竹林分,随时间进程子代分株表现出趋矮的迹象。

Abstract:

The effects of density regulation and rotation harvesting shoot on the shoot and young bamboo growth were studied under the different experimental treatments.The results indicated that:①The number of 1 year old daughter ramets in the treatment of 4~5-year-old mother ramets cutting was 1.92 times over that in the no cutting treatment; ②The rotational harvesting shoot improved the growth of daughter ramets, so the growth increments in height and diameter of 1 year old ramets were 1.5 and 1.4 times than those without treatment; ③There was a tend that the daughter ramets become short under the condition of current annual shoot picking.
