作为国家一级保护动物的大熊猫,其生活食品历来引起人们的重视。作为主要食源的竹子生长则是人的关注焦点。竹子是禾本科多年生植物,由种子萌发产生地下的茎和地上茎,经过几十年的营养生长,最后开花结果而死亡,完成一个生活周期进入下一生活周期。竹子的生活周期可分为下种更新、成林生长、开花结果三个阶段。在下种更新竹还未长起,大熊猫食物贫乏。如果有一部分竹子的生活周期与另一部分竹子的生活周期错开或者说不同步,一部分竹子开花结果死亡,另一部分竹子还处在生和阶段,保证大熊猫长有期
As a national animal protection giant panda, its food has always been of great importance. As the main source of bamboo growth is the focus of attention. Bamboo is a perennial gramineous plant that produces underground stems and shoots from seeds, which die after decades of vegetative growth and finally bloom to complete one life cycle and enter the next life cycle. Bamboo’s life cycle can be divided into the next update, forest growth, flowering three stages. In the next update, the bamboo has not grown yet, and the pandas lack food. If some bamboo life cycle and the other part of the life cycle of bamboo staggered or unsynchronized, part of the bamboo flowering result of death, the other part of the bamboo is still alive and stage, to ensure that the giant panda has a long period
