Abstract
The invention discloses a kind of germination accelerating method in winter of apocarya seed, first seed is carried out the water soaking process in three different water temperature stages, then the chemical liquid process of the concentrated sulfuric acid and potassium nitrate solution and the physical treatment of electromagnetism stationary magnetic field is carried out, the vernalization finally carrying out sealed spacer illumination is cultivated, through these three kinds of processing modes in conjunction with process, the time of sprouting of seed shortens greatly, and emergence rate improves, nursery stock regularity is also directly sowed than non-vernalization and is enhanced, and has very strong practical value.
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 logical straight, material is solid, and texture is careful, high resilience, not easily warping and fracturing, is the excellent material making furniture.And the thin easy stripping of shuck, kernel is plump, and be rich in fat, taste is fragrant and sweet, the raw material eating for dry fruit and extract oil.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 seed such as walnut and apocarya.Apocarya seed spring, Qiu Junke sowing.No matter be sow in spring or autumn sowing, seed is easily gnawed by mouse, bird.Sometimes weather arid, seed dehydration, emergence rate is low.Sow in spring and generally carry out in the last ten-days period in March or the first tenday period of a month in April.But be no matter sow in spring or autumn sowing, annual seedling is difficult to reach can the degree of grafting, generally needs ability grafting after two Growing season.This just needs a kind ofly can make cathay hickory seed in advance in the winter time or the method for germinateing the early spring, to ensure that its vegetative period extends, to realize the grafting carrying out seedling then.
Summary of the invention
Goal of the invention: in order to solve apocarya seed sprouting evening existing in prior art, the problem of seedling grafting cannot be carried out then, the present invention proposes one and can carry out vernalization to cathay hickory seed in the winter time, shorten the seed germination 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: gather healthy full seed after apocarya full maturity, removes broken shrivelled seed;
(2) pretreatment of seed: the water soaking 2-3h by the seed chosen by water temperature being first 0-10 DEG C, then the water soaking 1-2h by water temperature being 15-25 DEG C are finally the water soaking 1-2h of 35-45 DEG C by water temperature;
(3) seed chemical liquid soak: by step (2) process after seed air-dry rear first with 98% the concentrated sulfuric acid immersion 3-5min, air-dry after soaking complete washing, soak 12-36h with the potassium nitrate solution that mass fraction is 0.5%, sterilization is for subsequent use;
(4) physical treatment of seed: the seed after sterilization being completed carries out the process of electromagnetism stationary magnetic field, magnetic field intensity is 0.3-0.5T;
(5) vernalization: loaded in the plastic sack that totally can seal by the seed after having processed, put into constant temperature culture equipment after sealing and carry out vernalization, temperature is adjusted to 35-45 DEG C; Intensity of illumination is 300-600cd; Take 24 h dark to cultivate the interval illumination methods cultivated in conjunction with 24 h light and carry out vernalization cultivation.
Screen quality for improving seed screening effeciency, 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 seed to effective absorption ratio of water soaking, in described step (2), in the process of soaking, change water treatment every the immersion water of 30min to seed;
More preferred, in described step (5), in constant temperature culture equipment, humidity is 60%-80%, ensures that certain humidity contributes to seed fast germination.
Beneficial effect: the germination accelerating method in winter of a kind of apocarya seed provided by the invention, first seed is carried out the water soaking process in three different water temperature stages, then the chemical liquid process of the concentrated sulfuric acid and potassium nitrate solution and the physical treatment of electromagnetism stationary magnetic field is carried out, the vernalization finally carrying out sealed spacer illumination is cultivated, through these three kinds of processing modes in conjunction with process, the time of sprouting of seed shortens greatly, and emergence rate improves, nursery stock regularity is also directly sowed than non-vernalization and is enhanced, and has very strong practical value.
