油茶低产林改造技术研究

Research on Transformation Technology of Low YieldCamellia oleifera Forest

油茶林生长时间长,出现老化、大面积荒芜等是造成低产的重要原因。本文结合广东省肇庆地区油茶林种植的实际情况,对当地老化型低产油茶林和荒芜型低产油茶林的改造技术进行分析。因地、因林进行选择性技术改造是提高油茶产量的基本措施,是突破油茶产业做大做强瓶颈的关键所在。对于老化型低产林,在改造过程中,主要采用密林疏伐、稀林大苗补植以及更新改造等技术。对于荒芜型低产林,需要加强管理,做好除草松土、施肥保水、整型修剪以及果实采收。

Camellia oleifera forests have a long growth time,aging,and large-scale desertification are important reasons for low yield.This article analyzes the transformation technology of aged and barren low yield Camellia oleifera forests based on the actual situation of Camellia oleifera forest cultivation in Zhaoqing,Guangdong Province.Selective technological transformation based on local and forest conditions is a basic measure to increase the yield of Camellia oleifera and a key to breaking through the bottleneck of the Camellia oleifera industry's growth and strength.For aging low yield forests,techniques such as thinning of dense forests,replanting of large seedlings in sparse forests,and regeneration and transformation are mainly used during the transformation process.For barren low yield forests,it is necessary to strengthen management,including weeding and soil loosening,fertilization and water conservation,shaping and pruning,and fruit harvesting.
