锥栗老低产林改造试验

A Test on Remoulding the Old and Low-yield Forests of Castanea henryi Rehd et Wils

在锥栗主要产区建瓯县龙村乡建立低产林改造试验区,针对不同低产类型相应采取整形修剪、复壮树势、深翻垦复、科学施肥和病虫害防治等综合技术改造措施,低产林改造二年后比对照区增产4—10倍以上。

The test plots of remoulding low-yield forest of Castanea henryi Rehd etWils were established in Longcun Township of Jianou County--the main productionarea of C. henryi. The comprehensive technical remoulding measures, such as pruning,rejuvenation of tree vigor, deep tillage, scientific fertilizer application and pest control,were correspondingly taken for different types of low-yield forests. The notable effectsof increase in yield were gained two years after the remoulding of low-yield forests andthe yield in the remoulding plots increased by over 4--10 times as compared with that inthe check plots.
