Embodiment Construction

[0074] The sexual reproduction and breeding technology of dragon bamboo mainly includes the following steps: seed collection and screening, seed storage, sowing seedlings, preparation before planting of bagged seedlings, planting, tending, management and protection, selection of bamboo seedlings, control of diseases and insect pests, selection, and growth of bamboo investigation.

[0075] The seed collection and screening are as follows: when the seeds are collected, first cut down the bamboo plants, take off the branches with ears and dry them in the sun, then pick the seeds, and obtain pure seeds after winnowing and sorting. Elimination is carried out to ensure the quality of the seeds. The retained seeds after winnowing can be transported and stored by mixing with insecticides. When transporting, use a well-ventilated sack or sandbag.

[0076] Seeds with good quality can also be obtained by artificial methods. First, the bamboo clumps that are about to bloom are transplant...

Description

technical field [0001] The invention relates to a technology for sexual reproduction and breeding of dragon bamboo. Background technique [0002] Dragon Bamboo (D.yunnanicus Hsueg et D.Z.Li), is a genus of Bambusa genus in the Poaceae Bamboo subfamily, also known as Vietnamese Giant Bamboo (Guangxi), Dazhuo Bamboo, and Dazhu. It is native to Vietnam, Yunnan, China and other places. Bamboo species that love temperature and are afraid of cold, with annual rainfall of 1000-1800mm, annual average temperature of 17-21°C, minimum temperature of -2°C, frost-free period of 320 days, annual average relative humidity of more than 75%, loose, fertile, and PH value of 4.5-7.5 Grows well on moist soil. Stems up to 18-25m, diameter at breast height 11-22cm, tips drooping; internodes 40-60cm long, covered with small white bristles and slightly white powder when young; 1-3 main branches developed. Culm sheaths fall early, slightly shorter than internodes, leathery to thick leathery, light...
