摘要
[目的]调查西藏林芝地区光核桃的蕴藏量,为合理开发利资源提供理论依据。[方法]采用观测法、访问法和样地调查法研究西藏林芝地区光核桃结果规律与产量。[结果]挂果数量在前60d呈急剧下降趋势,60～135d数量相对稳定,135～165d又急剧下降。果实发育略呈S型曲线,前50d,幼果迅速发育,体积、重量增长较快;60～105d,体积、重量的增长速度最快;105～150d为成熟期,体积、重量的增大均不明显。产量与冠幅具有极好的相关性。林芝地区光核桃总蕴藏量按丰年计算为5300000～6900000kg。[结论]西藏林芝地区光核桃产量丰富,适宜规模化开发利用。
[Objective] The aim of the study was to find out the fruit growth rhythm and output of Prunus mira,and to afford theoretical basis for resource exploitation.[Method] Common view,interviewsurvey and sample plot survey was used to study fruit growth rhythm and output of Prunus mira in Nyingchi Prefecture of Tibet.[Result] The number of fruits on branch was sudden drop in the premier 60 dand the later period in 135-165 d,and was steady in 60-135 d.The process of fruits growth showed S-type line.In the premier 50 d,volume and weight grew rapidly,and were fastest in 60-105 d,not obvious in 105-150 d.The output of fruit was strong negative related with the grown width.The fruit total output was 5 300 000-6 900 000 kg in abundant year.[Conclusion] The fruit total output was abundant and suitable to scale exploitation.
