雷竹生长气象因子的相关分析

Interrelationship between Meteorological Factors and Growth of Lei Bamboo

本文论述雷竹出土生长、秆形生长、枝叶生长、竹鞭生长的规律及其与气象因子的相关关系，并提出了雷竹生长各阶段的适生温度和雨量．出笋起点温度９～１０℃，适宜温度１１～１３℃；秆形高生长适宜温度１７～１９℃，月降雨量不少于１３０ｍｍ，相对湿度达８５％以上；枝条生长的适温为２２～２５℃，在此期间降雨量不少于７０ｍｍ；竹叶生长的适温为１８～２５℃，日降雨量不能超过２７ｍｍ；竹鞭生长活跃期开始至停止的月均温为１３～１６℃，在月均温达３０℃，月降雨１４０～１６０ｍｍ时竹鞭生长最快．

This paper gives the good meterorological conditions for growth of Lei bamtoo.Bamboo shoots emerge from the earth at 9～10℃,and the air temperature of good for growth is 11～13℃.The height growth of bamboo trunk stem is normal at 17～19℃ with above 130mm monthly rainfall and 85% relative humidity.Bamboo branch develops suitably at 22～25℃ with above 700mm rainfall.The growth of bamboo leaves is vigor at 18～25℃,with under 27mm daily .Lei bamboo rhizome is active in growth at 13～16℃ average monthly temperature and is faster in growth speed at 30℃ average monthly temperature with 140～160mm rainfall.
