Flowering and fruiting of bamboo in Guizhou

From April 2009, the leaves of "Zhu Qian" (locally called firecrackers) in Banzhai, Maolan National Nature Reserve, Guizhou Province gradually withered, and by June 65438+ 10, the green bamboo forest turned yellow. If it is eaten by insects, all bamboo forests with a total area of more than 1000 mu for several kilometers in Fiona Fang will be spared. This phenomenon has attracted the attention of the Authority. 1in mid-October, Wei, deputy director and senior engineer of the reserve management bureau, led researchers into the forest area for field investigation.

According to the investigation, the large area of bamboo forest is not caused by insect pests, but by the rare physiological phenomenon of bamboo flowering. According to the memories of local people over 70 years old, the last large-scale fireworks bloom in Banzhai area was in 1953, about one year ago. Even middle-aged and elderly people born and raised in the local area rarely see such a scene with their own eyes.

At present, the flowering period of Guizhou bamboos in this area has passed, and the seeds of a few bamboos have basically matured, and the seeds of wheat grain size are oval or oval and milky white.
