Key techniques of transforming low-yield forest of Camellia oleifera
To improve the yield of low-yield forest of Camellia oleifera and promote the high-quality development of Camellia oleifera industry.Based on the reconstruction practice of low-yield forest of Camellia oleifera,three key techniques of care and reform,grafting and crown change,and renewal and transformation were summarized,which were suitable for the reconstruction of different types of low-yield forest Camellia oleifera.In terms of nurturing and transformation technology,it include reasonable control of density through thinning,pruning,and replanting,scientific pruning,removal of weak and excessively long branches,selection of deep excavation methods based on forest conditions,reasonable fertilization,bee pollination,and timely harvesting according to local climate conditions and planting varieties;the techniques of grafting and crown change include selection of appropriate grafting time and spike,tight grafting dressing and moisture after grafting,etc.There are two kinds of regeneration technology:dry cutting regeneration and afforestation regeneration,dry cutting regeneration is to cut off the main stem of the old and weak Camellia oleifera tree at a distance of 10-20 cm from the ground,keeping the cutting edge flat;afforestation regeneration includes land preparation,good seed and seedling strengthening,planting management and tending management.This article provides technical references for the reconstruction of low-yield forest of Camellia oleifera and related forest.
