Description
Technical field
The invention belongs to planting technology field, be specifically related to a kind of method improving gingko seeds germination percentage.
Background technology
Semen Ginkgo is Ginkgoaceae, Ginkgo deciduous tree, and gymnosperm has another name called maidenhair tree, Gong Sunshu etc..Semen Ginkgo occurs in
Before 2.7 hundred million years, it is to carry over the most ancient few survivors seeds after quaternary glacier moves, have the title of " living fossil ".Semen Ginkgo has
High economic worth, medical value and Landscape Application is had to be worth.Abundant flavonoid is all contained such as Folium Ginkgo and seed
The special effective ingredient such as compound, terpene lactone, has regulation opposing immunity, prevention effect such as senile dementia and diabetes.
The modes of reproduction of Semen Ginkgo mainly has the methods such as seed propagation, tillering propagation, cottage propagation and propagation by grafiting.Wherein, sow numerous
Grow most widely used general, typically use field seeding.Because gingko seeds seed coat is thicker, typically require before seeding and seedling raising and locate
The most more reason, to improve its bud ratio, use the methods such as husky Tibetan, water logging, HORMONE TREATMENT, though certain effect can be played, but still reach
Less than it is intended that level.
Summary of the invention
It is desirable to provide a kind of method improving gingko seeds germination percentage.
The present invention is achieved through the following technical solutions:
A kind of method improving gingko seeds germination percentage, comprises the steps:
(1) seed selection:
Choose full grains, bright in color, ripe gingko seeds without pest and disease damage, standby after sieving and washing removing impurity；
(2) seed treatment:
The seed that step (1) is chosen is put into immersion treatment 40 ~ 50min in the potassium permanganate solution that volumetric concentration is 0.3 ~ 0.4%
After, taking-up clear water is rinsed well, then puts it in seed-soaking liquid immersion 3 ~ 4h, is finally drawn off rinsing well with clear water standby
With；The material that described seed-soaking liquid by following percentage by weight is forms: potassium nitrate 0.2 ~ 0.4%, sodium chloride 0.3 ~ 0.5%, amine are fresh
Ester 200 ~ 300ppm, lead tetrachloride 0.01 ~ 0.03%, compound vitamin 0.5 ~ 1%, sucrose 0.5 ~ 1%, magnesium sulfate 0.2 ~ 0.5%, remaining
Amount is water；With potassium, sodium, lead, magnesium elements, gingko seeds is coerced, the activity of seed can be improved, promote that it is sprouted, complex amine
The action effect of fresh ester is more preferably；
(3) accelerating germination processes:
A. the gingko seeds after step (2) being processed is put in glass jar, fills alkaline water in glass jar；Solution acid-basicity is
Affecting a key factor of seed germination, people typically seek optimal pH value and carry out immersion treatment, but in actual applications
Find, although weak acid (pH value is 6.0 ~ 7.0) and weak base (pH value is 7.0 ~ 8.0) are for the sprouting of ginkgo seed immersion treatment
Facilitation effect is higher, but cannot be further continued for after reaching certain bottleneck promoting, and selects alkaline of a relatively high alkaline water, coordinates tool
There is the microwave treatment of stronger seed modifying function, there is good synergy, and weak acid (pH value is 6.0 ~ 7.0) or weak base
(pH value is 7.0 ~ 8.0) solution does not but reach this effect, may is that it is for Interior Seed material influence degree and effect
Mechanism is different, and the of a relatively high alkaline water of alkalescence improves the activity of the moieties that the above two cannot promote, and for majority
The inhibitory action of material has carried out making up, improving by microwave, and then overcomes the bottleneck problem of lifting；
B. putting in germinating box by the glass jar of operation a gained, the temperature controlled in germinating box is 27 ~ 32 DEG C；
C. in germinating box, gingko seeds is applied microwave treatment simultaneously；Microwave can improve the work of the materials such as seed majority enzyme
Property, promoting it sprouts, and coordinates the use of alkaline water, and effect is the most excellent；
D. seed is taken out and can sow after processing 6 ~ 8h by common accelerating germination.
Further, containing vitamin A, vitamin B1, FA, dimension in the compound vitamin described in step (2)
Raw element C, vitamin D and vitamin K.
Further, the alkaline water described in step (3) operation a is that distilled water is adjusted to pH value is 8.5 ~ 9.5 to form,
It puts into the mass ratio in glass jar with gingko seeds is 4 ~ 5:1.
Further, the power of the microwave treatment described in step (3) operation c is 400 ~ 500W.
There is advantages that
The seed-soaking liquid that the present invention is prepared by uniqueness, and special accelerating germination process, can well improve ginkgo seed
Characteristic, has broken its dormancy, promotes it and sprouts, and removes base portion seed coat, the most husky Tibetan being made without mechanical damage
The mode of operation that process etc. takes time and effort, just can accelerate the sprouting of seed, and germination percentage is promoted to more than 96%, compares existing
Methodical germination percentage improves more than 15%, and germinating time correspondence shortens about 5 days.Additionally, in the comprehensive cooperation of each step
Under, the characteristic of seed is improved, and raised an infant Seedling body constitution also obtains corresponding change, seedling drought-enduring, Salt And Alkali Tolerance performance is relatively strong, carry
The high survival rate of seedling replanting, the plantation having expanded ginkgo is cultivated scope, is had good promotional value.
