摘要：印楝幼树生长 1a抽 3次梢 ,即春梢 (2　 4月 )、夏梢 (6　 8月 )和秋梢 (10月 )。幼林树高、地径的连年生长量在栽后第 1a最大 ,第 2a最小 ,以后各年较一致。 1a中印楝季节性生长分为 3个时期 ,即滞生期 (1　 3月和 11　 12月 ) ,生长量较小或生长停缓 ;生长期 (4　 10月 ) ,生长量明显 ;快速生长期 (5　 8月 ) ,树高的生长高峰出现在 7、8两月 ,占全年生长量的 6 2 1% ,地径的生长高峰开始比树高生长高峰早 ,结束得晚。月平均温度对当月树高、地径生长量的相关关系均达显著程度 ;月平均降水对当月树高生长量的影响也达显著程度 ,但对当月地径生长量的影响不显著。月平均温度对树高和地径生长的影响较月平均降水量的大。造林保存率较高 ;定植后第 2a结果株率为 5 3 3% ,到第4a为 93 1%。
Annual growth rhythm, growth pattern of height and caliper of young trees of Azadirachta indica were studied. The results indicates that the annual sprouting period can be divided into 3 stage: spring phase (from February to April), summer phase (from June to August) and autumn phase (October). According to the growth dynamic of height and caliper, the young trees grows rapidly in the first year after being planted, growing slowly in the second year, and then growing evenly in the third to seventh year. The annual growth patterns of height and caliper showe that the growing period is 6 months (from April to October), and begin to grow rapidly from May to October. The height growth in two months (July and August) reaches 62.1% of the year's total. Correlativity of the monthly mean temperature to the growth of height and caliper, and rainfall to the growth of height are striking. The temperature has more important effect on the height growth than the rainfall. The survival percentage of young neem plantation is very high. 53.3% of trees fruited among 2 years plantation and 93.1% of them fruited in 4 years plantation.
