摘　　要：以吉林长春地区主栽越橘品种"北陆"、"蓝丰"、"美登"为试材,对其株高、冠幅、延长枝、基生枝等各项指标进行测定,研究其年周期变化规律,得出关于长春地区主栽越橘品种的生长动态规律,以期对栽培管理和肥水管理起到指导作用。结果表明:株高快速生长阶段是在整个8月份,冠幅的快速增长的阶段是在7月末至8月末,与株高快速增长阶段相一致;果实采收期是在7月末至8月初。可见越橘树体空间增长是在果实成熟以后开始的,此时要注意肥水管理,以便提供充足的水分养料,来供给树体的快速增长;延长枝从7月初到8月末一直保持着快速生长状态,基生枝的快速生长也是集中在7月初到8月中旬。从7月初至9月末,新梢的整体生长速度趋势呈现出"快-慢"趋势,树体营养生长与生殖生长同时进行,所以,在此期间要加强肥水管理,来保持越橘营养的正常供应,为翌年的高产做好准备。With the main varieties of ＇Northland＇, ＇Bluecrop＇, ＇Blomidon＇ as test materials in Jilin Changchun area,the plant height,canopy diameter, extended branch, base born branch were determined, and the years of change rule were studied,growth dynamic regulation were got about Ghangchun area cranberries, in order to provide a guiding roie in cultivation management and fertilizer management. The results showed that fast： growth stage of plant height was in the whole August,rapid growth stage of crown width was in late July to late August, accordance with plant height rapid growth stage,fruit harvest time was in late July to early August, the body space growth was later than fruits mature time,at this time,water and fertilizer management should be pay attention to,in order to provide sufficient fertilizer,to supply the rapid growth of the tree body ; extended branch maintained a rapid growth from early July to late August,and base born branch rapid growth was concentrated in early July to middle August too. From early July to late September,the newbranch growth rate present a ＇quick-slow＇ trend,the vegetative growth and reproductive growth at the same time, in this period should be appropriate for water management,to keep the nutrition normal supply,for next year;s high yield.
