摘要
引种台湾青枣 5个品种至辽宁省朝阳市 ,为适应棚内栽植 ,进行了主干更新试验以确定各品种的最佳截干高度。试验结果表明 :(1)主干更新是棚栽台湾青枣必不可少的一项重要栽培措施 ;(2 )截干高度以 30cm为佳 ;(3)主干更新高度在各品种间差异不显著。
Five varieties of Ziziphus mauritiana have been introduced beyond its native northern range to Chaoyang City,Liaoning Province.In order to confirm the suitable stumped height and control the height of the trees,coppice management of the five varieties trees at different height was taken in March,2003.The following conclusions were drawn on investigation of growth and fructification.(1) Coppice management was one of the most important cultivation technologies,especially in horticultural greenhouse;(2)30?cm was the most suitable height of coppice management;(3) The suitable height of coppice management was the same with the five varieties.
