Abstract
The invention discloses a method for promoting germination of oriental oak seeds. The method is characterized by comprising the following working procedures: seed collection, seed pretreatment, sand storage germination acceleration and breeding management. The collected ripen oriental oak seeds are subjected to selection, disinfection, immersion and auxin treatment, and then sand storage germination acceleration is performed; germinated seeds can be obtained by breeding management. According to the method for promoting germination of the oriental oak seeds, seed dormancy can be effectively broken through only by immersion in plant hormone with a proper concentration and sand storage treatment; therefore, germination of the seeds can be accelerated, and the germination rate can be improved; the technical operation is simple, the cost is low, the operation is convenient, and the method is suitable for being popularized, and has higher economical, social and ecological benefits.
Description
Technical field
The present invention relates to the germination accelerating method of seed, specifically a kind of method promoting cork oak seed germination.
Background technology
Cork oak (
quercusvariabilisBl) have another name called cork oak, tertia Qinggang, hemp oak, be that Fagaceae (Fagaceae) oak belongs to arbor, tree crown is extensively avette, and trunk is many, taupe, dark lobe, and cork layer spy is thick.Sprig is filbert, and male inflorescence is born in annual shoot bottom, and female flower list is raw or twin with annual shoot axil.May at florescence; The fruit 9-10 month in next year is ripe.Chinese important commerical tree species.Cork oak happiness light, be often born in mountain region tailo, but treelet is there to be lateral shelter as well.To weather, the strong adaptability of soil.The low temperature of ability-20 DEG C, in the acidity of pH4-8, all has growth in neutral and limy soil, also drought-resistant, barren and with deep, fertile, suitably moistening and well-drained loam and sandy loam optimum, not resistance to ponding.Produce the provinces and regions such as Liaoning, Hebei, Shanxi, Shaanxi, Gansu, Shandong, Jiangsu, Anhui, Zhejiang, Jiangxi, Fujian, Taiwan, Henan, Hubei, Hunan, Guangdong, Guangxi, Sichuan, Guizhou, Yunnan.North China is born in the tailo of height above sea level less than 800 meters usually, and southwest can reach height above sea level 2000-3000 rice.
At present, the planting type that cork oak is common is afforestation seeding.Because cork oak seed belongs to hardseed, have several factors to cause seed germination success rate low in natural germination process, the reduction of resource is not supported in the sprouting naturally of seed far away.And often only have about 50% without the cork oak percentage of seedgermination of any hormone agents process in traditional mode of production, and germinating time evening, emerge irregular, limit the large-scale planting of cork oak.
Summary of the invention
Object of the present invention is the deficiency overcoming existing cork oak Seed germination techniques, provides a kind of germination rate and the quickening germination physiology that can improve cork oak seed, workable, practical simplicity, the method for the promotion cork oak seed germination that cost is low.
Technical scheme of the present invention is as follows:
A kind of method promoting cork oak seed germination, comprise the operation that seed collection, Seeds preprocess, husky Tibetan vernalization and breeding are managed and protected, by gathering ripe cork oak seed, carry out choosing seeds, sterilize, soak seed and implement after gibberellin process sand and hide vernalization, managed and protected the seed obtaining germinateing by breeding, main operational steps is as follows:
(1) seed collection: autumn gathers ripe cork oak seed, is placed in airtight container 2 ~ 3 days;
(2) Seeds preprocess:
1. choose seeds: by the cork oak seed clean water after encapsulation process, then spread ventilating, without the indoor of direct sunlight, the impurity such as artificial removal's acorn-cup, sprig, blade, and removing have worm channel, form not just, have and damage and seed that form is too small;
2. sterilize: the liquor potassic permanganate clean cork oak seed being put into volumetric concentration 0.3% soaks 40 ~ 50min, then pulls out, dries in the shade after rinsing well with clear water;
3. soak seed: the clear water of the cork oak seed after sterilization is soaked 2 ~ 3d, makes its abundant imbibition; In clear water, fully stir cork oak seed again, then leave standstill, remove the floater or ghost seed that swim on the water surface, finally repeatedly wash remaining seed by rubbing with the hands, after cleaning, cork oak seed is pulled out and drain;
4. gibberellin process: the Gibberellins solution cork oak seed after seed soaking being put into 300 ~ 500mg/L soaks 1 ~ 3d;
(3) husky Tibetan vernalization: the baking oven first river sand cleaned up being placed in 100 ~ 140 DEG C is dried, naturally cool to room temperature, then sand is loaded in flowerpot, with the moistening sand of clear water, cork oak seed is shared equally on sand, flowerpot is placed in nursery, covers clean fine sand thin layer, and use covered rearing with plastic film moisturizing;
(4) breeding is managed and protected: to flowerpot periodically sprinkle bactericide during seed sand Tibetan, and according to moisture evaporation situation in sand, sprays a small amount of clear water in good time, keep sand to be suitable for humidity.
Preferably, the cork oak seed in above step (3) and sand are share equally after the ratio of 1:5 is puddled by volume.
Preferably, the even stand thickness described in above step (3) is no more than 20cm; The thickness of the clean fine sand of described covering is 2 ~ 3cm.
Preferably, the periodically sprinkle bactericide described in above step (4) be with volumetric concentration be 1 ‰ Baijunling solution to sterilization in the flowerpot of breeding bed, every 8 ~ 10d spray once; Every day to spray water in the flowerpot of breeding bed once, sprays once husky bed every 10d; Described suitable humidity is that agglomerating, the humidity of scattering of loosing one's grip held by sand.
The present invention relative to prior art, the advantage had and good effect as follows:
1, the method for promotion cork oak seed germination of the present invention, do not need to divide the not easy-operating modes such as cotyledon through mechanical damage removal base portion seed coat, removal unit, only need soak and Sand culture by the Gibberellins solution of suitable concentration, accelerate seed germination and improve germination rate, sprout nearly 20 days than in traditional mode of production in advance without the cork oak seed of any hormone agents process, germination rate improves more than 30%.
2, the method for promotion cork oak seed germination of the present invention, cork oak seed is through gibberellin process and bury vernalization with fine sand, and sprout and shorten perdurabgility, germination peak period Relatively centralized, bud seedling high-quality, whole structure is good.
3, the present invention is placed in nursery by being equipped with the husky flowerpot hiding seed, and with covered rearing with plastic film, and moisturizing is carried out in timing watering, allows seed sprout in its natural state, is applicable to producing.
4, the present invention's potassium permanganate carries out disinfection to seed, and with the mode process sand of high-temperature sterilization, effectively prevents cork oak seed to produce and go mouldy, improve the germination rate of cork oak seed
5, the method for promotion cork oak seed germination of the present invention, technological operation is simple, with low cost, handled easily, is applicable to promoting, and has good economic benefit, social benefit and ecological benefits.
