Description
Technical field
The invention belongs to agricultural plantation technology fields, and in particular to a kind of Structure of Seed of Davidia Involucrata method for culturing seedlings of high-survival rate.
Background technique
Dove tree is deciduous tree.15 ~ 25 meters of height can be grown into, leaf is extensively oval, and there is sawtooth at edge.Graminaceous plant only has one
Belong to two kinds, two kinds similar, and only a kind of blade face hairiness, another davidia involucrata var. vilmoriniana are smooth surfaces.The odd beauty of dyeing defect is new before 10,000,000 years
The raw Relict Plant left for the Tertiary Period, in quaternary glacier period, the dove tree of most area becomes extinct in succession, only in China
Southern some areas survive." living fossil " for becoming plant kingdom's today, because its flower-shape exactly like the pigeon spread its wings to fly,
Its capitulum and is named as " Chinese pigeon tree " by west botanist as the head of pigeon, also known as " pigeon flower tree ", wild
Kind is only grown in Southwest China Sichuan Province, Yunnan Province and middle part Hubei Province and surrounding area.Dove tree has the title of " plant living fossil ",
The treasure in national 8 kinds of level-one national key protected plants, since the felling of forest destroys and excavates wild seedling (tree) planting, quantity compared with
Few, distribution also increasingly reduces, if not taking safeguard measure, there is the danger substituted by other deciduous species.
Although dove tree has researched and developed decades, due to seed growing problem.It does not all train largely all parts of the country
It educates, plant, substantially invisible on the major nursery stock markets in the whole nation, price is high.Such as 5 centimeters of rice diameter, 300 yuan of dove tree price
Left and right, and the rare tree price of other 5 centimeters of various rice diameters is all at 50 yuan or so.It can be seen that if not solving Structure of Seed of Davidia Involucrata breeding
Problem, dove tree cannot develop in batch at all, plant.Since Structure of Seed of Davidia Involucrata shell is hard, ripening time is long, and seed will next year
