摘要
实生繁殖、经营管理粗放是造成板栗产量低、品质差的重要因素 .通过采取良种高接换冠 ,结合树体修剪、抚育施肥、栗粮间作、病虫害防治等综合技术措施 ,对 1 0～ 1 2年生低产栗园实施改造 ,产量由改造前的 1 0 8.6kg /hm2 提高到 1 2 6 0 .45kg/hm2 ;2年生幼树经过嫁接改造提早 2～ 3a结实 .
Seeding propagation and extensive management were important factors that resulted in low yield and poor quality.By canopy replacement by high grafting elite breed and integrated measures such as pruning,tending,fertilization,intecropping with grain crops and pest and disease control,low-yield Castanea mollissima of 10-12 years were transformed and their yield was improved from 108.6 kg/hm 2 to 1 260.45 kg/hm 2.The grafted young trees of 2 years fruited 2-3 years ahead of due time.
