Abstract
The invention discloses a winter germination-accelerating method of apocarya seeds. The winter germination-accelerating method comprises the steps of firstly immersing the seeds in water at three different water temperature ranges; then carrying out chemical solution treatment by using concentrated sulfuric acid and potassium nitrate solutions and physical treatment by using an electromagnetic constant magnetic field; and finally carrying out germination-accelerating culture in sealed illumination at intervals. Through combined treatment of the above three manners, a germination time of the seeds is greatly shortened, rate of germination is increased, and uniformity of seedlings has greater improvement than that in direct sowing without accelerating germination. The winter germination-accelerating method has very high application values.
Description
Technical field
The present invention relates to the planting technology of cathay hickory, especially relate to a kind of germination accelerating method in winter of apocarya seed.
Background technology
Apocarya is world-renowned high-grade dry fruit, oil plant seeds and material fruit dual-purpose fine tree species, originate in the U.S., this seeds economic worth is high, and afforestation landscaping effect is good, and lumber quality is good, its trunk is perfectly straight, material is solid, and texture is careful, high resilience, being difficult for warping and fracturing, is the excellent material of making furniture.And the thin easy stripping of shuck, kernel is plump, is rich in fat, and taste is fragrant and sweet, the raw material of and oil expression edible for dry fruit.In addition, it is wet that it is water-fast, and planting in around applicable river alongshore, lake and flat area " four is other ", can do street tree and shade tree.
The stock of apocarya grafting is the seedling of the seeds such as walnut and apocarya.Apocarya seed spring, Qiu Junke sowing.No matter be to sow in spring or autumn sowing, seed is easily gnawed by mouse, bird.Sometimes weather is arid, seed dehydration, and emergence rate is low.Sow in spring and generally in the last ten-days period in March or the first tenday period of a month in April, carry out.But no matter be to sow in spring or autumn sowing, annual seedling is difficult to reach degree that can grafting, generally need to could grafting after two growth seasons.This just need to a kind ofly can make the method that cathay hickory seed shifts to an earlier date in the winter time or germinate the early spring, to guarantee its prolongation in vegetative period, to realize the grafting of carrying out then seedling.
Summary of the invention
Goal of the invention: in order to solve in prior art existing apocarya seed sprouting evening, cannot carry out then the problem of seedling grafting, the present invention proposes and a kind ofly can to cathay hickory seed, carry out vernalization in the winter time, shorten seed and sprout the cycle, and improve the germination accelerating method in winter of the apocarya seed of seeding ratio.
Technical scheme: to achieve these objectives, the present invention takes following technical scheme: a kind of germination accelerating method in winter of apocarya seed, comprises the following steps:
(1) preparation of seed and screening: after apocarya full maturity, gather healthy full seed, remove broken shrivelled seed;
(2) pretreatment of seed: being first the water soaking 2-3h of 0-10 ℃ by water temperature by the seed of choosing, then being the water soaking 1-2h of 15-25 ℃ by water temperature, is finally the water soaking 1-2h of 35-45 ℃ by water temperature;
(3) chemical liquid of seed soaks: seed after step (2) is processed is air-dry first soaks 3-5min with 98% the concentrated sulfuric acid afterwards, soak after complete washing air-dry, the potassium nitrate solution that is 0.5% with mass fraction immersion 12-36h, sterilization is standby;
(4) physical treatment of seed: the seed after sterilization is completed carries out the processing of electromagnetism stationary magnetic field, magnetic field intensity is 0.3-0.5T;
(5) vernalization: the seed after finishing dealing with is packed in the plastic sack that totally can seal, put into constant temperature culture equipment and carry out vernalization after sealing, temperature is adjusted to 35-45 ℃; Intensity of illumination is 300-600Lx; Take 24 hours dark culturing to carry out vernalization cultivation in conjunction with the interval illumination methods of 24 hours illumination cultivation.
For improving seed screening effeciency, screened quality, in described step (1), the screening of seed can take seed screen box or seed hair-dryer to remove not full particle and other foreign material.
For improving the effective absorption ratio of seed to water soaking, in described step (2), in the process of soaking, every 30min, the immersion water of seed is changed to water treatment;
More preferred, in described step (5), in constant temperature culture equipment, humidity is 60%-80%, guarantees that certain humidity contributes to seed to germinate fast.
Beneficial effect: the germination accelerating method in winter of a kind of apocarya seed provided by the invention, first seed being carried out to the water soaking in three different water temperature stages processes, then carry out the chemical liquid processing of the concentrated sulfuric acid and potassium nitrate solution and the physical treatment of electromagnetism stationary magnetic field, finally carrying out the vernalization of sealed spacer illumination cultivates, combination through these three kinds of processing modes is processed, the time of sprouting of seed shortens greatly, and emergence rate improves, nursery stock regularity also than vernalization not directly sowing be enhanced, there is very strong practical value.
