Abstract
The invention relates to a seed sprouting method, and in particular relates to an efficient sprouting method for davidia involucrate. The efficient sprouting method comprises the following steps: 1. from the middle of September to early October, picking up mature davidia involucrate fruits with purple brown surfaces; 2. flatly spreading the mature davidia involucrate fruits on a stone plate, then covering the fruits with another stone plate on the top, and then moving the stone plate back and forth with a great force so that the hard pericarp is damaged due to external force friction; 3. mixing 1000 times caustic soda aqueous solution in a proportion of 10%-50% with fresh human urine to prepare germinating liquid, and then barrelling; 4. completelysubmerging the mature davidia involucrate fruits with damaged pericarp into the germinating liquid, and then capping; and 5. after 30-60 days, fishing out treated seeds, placing the seeds into a bamboo basket, washing the seeds to be clean with clear water, mixing with plant ash and sowing the seeds. The method provided by the invention is simple and efficient, and can effectively break or soften hard pericarp of davidia involucrate and improve the germination rate of davidia involucrate to be above 95%.
Description
Technical field
The present invention relates to seed accelerating germination method, relate in particular to the efficient germination accelerating method of dove tree.
Background technology
Dove tree, Nyssaceae, dove tree belongs to, and claims again pigeon tree, pigeon Hua Shu, water pear etc., is a kind of very beautiful deciduous tree.Between annual four, May, blooming, have two pieces of white bracts that differ in size under its capitulum, be Long Circle or oval, as pigeon, unfold dipteron, is famous in the world ornamental tree species.Dove tree is Relict Plant in the Tertiary Period, and the aspects such as research palaeoflora and systematic growth are had much to scientific value, is country-level focused protection wild plant.
The fruit of dove tree is ellipticity or square shape is avette, pericarp meat, and surface is puce, above has the numerous circular spot of Dark grey.Fruit stone is oblong, and long 3 to 4 centimetres, 1.5 to 2 centimetres of diameters, look, as walnut shell, above has vertical rib, and endocarp sclerotin is very hard, and tool rill inside has 5 to 7, seed.Because endocarp is very hard, it is few that the fruit naturally dropping in woods is sprouted naturally, and wanting artificial propagation dove tree must process fruit.
Summary of the invention
The efficient germination accelerating method that the object of this invention is to provide a kind of dove tree, solution dove tree is hard because of pericarp, is difficult to germinate or the extremely low problem of germination rate under nature.
The present invention is achieved through the following technical solutions: the efficient germination accelerating method of dove tree, its feature comprises the steps:
(1) mid-September to early October is plucked the ripe dove tree fruit that surface is puce;
(2) ripe dove tree fruit is shakeout and is placed on slabstone, then on fruit, add a cover again a slabstone, then firmly move back and forth slabstone, make hard pericarp because of external force friction impaired;
(3) proportion is accounted for to 1000 times of caustic-soda aqueous solutions of 10% to 50% and mix with Freshman urine, make vernalization liquid, then barrelling;
(4) the impaired ripe dove tree fruit of pericarp is put into vernalization liquid, allow liquid all flood fruit, then add a cover;
(5) after 30-60 days, then the seed of processing is pulled out and put in bamboo basket, with clear water, rinse well, can sow after mixing ash.
Method provided by the invention is simply efficient, can effectively to the hard fruit shell of dove tree, carry out fragmentation or softening, and the germination rate of dove tree is reached more than 95%.
Embodiment
With most preferred embodiment, the present invention is elaborated below.
Embodiment: the efficient germination accelerating method of dove tree.
(1) to pluck the ripe dove tree fruit that surface is puce standby mid-September to early October.
(2) ripe dove tree fruit is shakeout and is placed on slabstone, then on fruit, add a cover a slabstone again, slabstone area is 1.5 square metres, and weight is 75kg.Then firmly move back and forth slabstone, make hard pericarp because of slabstone friction impaired.
(3) proportion is accounted for to 1000 times of caustic-soda aqueous solutions of 30% and mix with Freshman urine, make vernalization liquid, then barrelling;
(4) the impaired ripe dove tree fruit of pericarp is put into vernalization liquid, allow liquid all flood fruit, then add a cover, be 40 days standing time.
(5) and then by the seed of processing pull out and put in bamboo basket, with clear water, rinse well, can sow after mixing ash, the germination rate of seed can reach more than 95%.
Claims (3)
1. the efficient germination accelerating method of dove tree, its feature comprises the steps:
(1) mid-September to early October is plucked the ripe dove tree fruit that surface is puce;
(2) ripe dove tree fruit is shakeout and is placed on slabstone, then on fruit, add a cover again a slabstone, then firmly move back and forth slabstone, make hard pericarp because of external force friction impaired;
(3) proportion is accounted for to 1000 times of caustic-soda aqueous solutions of 10% to 50% and mix with Freshman urine, make vernalization liquid, then barrelling;
(4) the impaired ripe dove tree fruit of pericarp is put into vernalization liquid, allow liquid all flood fruit, then add a cover;
(5) through after a period of time, then the seed of processing is pulled out and put in bamboo basket, with clear water, rinse well, can sow after mixing ash.
2. the efficient germination accelerating method of dove tree as claimed in claim 1, is characterized in that the impaired ripe dove tree fruit of pericarp being put into vernalization liquid described in (4) step, and be 30-60 days standing time.
3. the efficient germination accelerating method of dove tree as claimed in claim 1, is characterized in that adding a cover a slabstone above the fruit described in (2) step, and slabstone area is 0.5-1.5 square metre, and weight is 25kg-75kg.
