Abstract

The invention discloses a method for breaking the dormancy of nitraria tangutorum bobr seeds, relates to a treating method of seeds, and belongs to the technical field of agriculture. The method is characterized by comprising the following steps of: firstly, soaking the nitraria tangutorum bobr seeds by warm water, soaking the seeds for 30-60min by potassium permanganate solution with the concentration being 0.5-2%, and washing by clean water for 2-3 times; and treating the seeds washed by clean water by 10-15ppm of gibberellin diluent and moss leach liquor respectively, and sowing. The method has the beneficial effects that after the method is used, the seeds are soaked by the warm water, and the seeds are soaked by the potassium permanganate solution, so that the skins of the seeds are thinned, the germination rate of the seeds can be increased, and the potassium permanganate has the actions of sterilization, badness eliminating and the like; the seeds are treated by the gibberellin diluent and moss leach liquor, so that the treating time of the nitraria tangutorum bobr seeds can be shortened, and the time cost can be reduced; a natural plant seed germination promoter is used, so that the effective constituents of the nitraria tangutorum bobr can be improved, and the use requirement can be met; and the method is ordered in emergence rate, and a plant is high in external adaption performance.

Description

A kind of seed dormant method of white thorn of breaking

Technical field

The present invention relates to a kind of processing method of seed, belong to agricultural technology field, specifically a kind of seed dormant method of white thorn of breaking.

Background technology

White thorn ( Nitraria tangutorum Bobr.) be zygophyllaceae ( Zygophyllaceae) Nitraria (Nitraria L.) plant, the aerial growth of often crawling, plant height 30～50cm, multi-branched, the small part branch is upright, and bark is faint yellow, the sprig canescence, most advanced and sophisticated thorn-like, branch is stingless or few thorn.Its adaptability is extremely strong, and drought-enduring, saline and alkaline, cold-resistant, the wind resistance, high temperature resistant, barren-resistant of happiness is Desert Area and desert Plain typical plant, is the saline soil indicator plant in the cold temperature of China, mild climate district.Its fruit has the blood sugar of adjusting, blood fat, and is hypotensive, improves effects such as body immunity, antifatigue, cold resistance, enhancement sleep, also have Appetizing spleen-tonifying, prevention and treatment cardiovascular and cerebrovascular disease, anti-ageing, nourishing and body-strengthening, multiple efficacies such as protection against chemical liver damage.White thorn is nitrogen fixedly, increases soil nutrient, improves the soil nutrient situation, is the important ecological vegetable in NORTHWEST CHINA area, and white thorn distributes extensively in western husky district, forms big and small white thorn heap; Have very strong weather-proof sand fixation, can also create conditions for the existence of other species in the plant community.But, be at present that husky drought in imminent danger is given birth to the single-minded host plant of traditional Chinese medicine cynomorium songaricum in recent years because western eco-environment is destroyed, and the distribution area of white thorn dwindles day by day.

The berry of white thorn is a kind of special wild fruit resource of desert area, because of its color and taste, shape and big or small similar cherry, so the good reputation of " desert cherry " is arranged, contain rich saccharide in pulp and the fruit juice and account for dry weight 26%, the trace element 24 in and 18 seed amino acids, wherein the content of 12 seed amino acids is higher than sea-buckthorn, and 5 kinds exceed 2～10 times; Vitamin C is abundant, contains 31.12mg in every 100g fruit.White thorn has diseases such as treatment is weakness of the spleen and the stomach, indigestion, neurasthenia, flu, and directly edible white thorn fresh fruit has very high nutrition and medical value.And Nitraria has male abortion phenomenon more, the probability of interspecific cross is high and variation is big, ecotype is numerous and jumbled, but along with arid area population increase and modern agricultural development, ecotope suffers unprecedented destruction, groundwater resources a series of environmental problems such as exhaustion, vegetation degeneration, the soil salinization, desertization day by day occurred.White thornbush is because the deterioration in succession of its habitat sand hill moisture condition, and soil moisture content is far below its coefficient that here withers, and the serious degradation phenomenon occurs.Seminal propagation is the white important stage that stings the history of life, and therefore, research white thorn seed sprouting rule and countermeasure help the screening of white thorn large tracts of land artificial cultivation popularization and excellent strain thereof.White thorn seed has very strong hibernation feature, and the kind skin is hard, and it is bigger normally to sprout difficulty, and is difficult without the seed sprouting of any processing, need carry out certain processing to improve germination rate to seed.

Summary of the invention

The object of the present invention is to provide a kind of seed dormant method of white thorn of breaking, solved the present situation of traditional white thorn seed germination difficulty,, improve white thorn seed germination rate, shorten white thorn breeding time for production practices provide effective ways.

For achieving the above object, a kind of seed dormant method of white thorn of breaking of the present invention is characterized in that:

One, adopts the high-quality white thorn seed of results last year,, with 0.5～2% liquor potassic permanganate, the 30～60min that soaks seed, wash 2～3 times with clear water more then prior to seeding earlier with flush away pulp behind 40～60 ℃ of emerge in worm water 20～40h;

Two, the seed that clear water was washed is handled 20～40h with the gibberellin dilution of 10～15ppm, pulls seed out, seed is placed moss leaching liquor continuous culture 2～4 days in 20～28 ℃ of insulating boxs again, can sow.

The preparation method of described gibberellin dilution is for earlier dissolving gibberellin with alcohol, and meltage is 0.2～0.3g/ml, and then it being converted water, will to become gibberellin concentration be 10～15ppm;

The preparation method of described moss leaching liquor is that the moss of gathering is used flushing with clean water, remove the impurity that is clipped in wherein, clean with distilled water flushing again, dry in the shade to be placed in 20～30 ℃ of insulating boxs and dry, pulverize prepares leaching liquor, and described moss water extract concentration is 0.01～0.03g/ml.

Described gibberellin can improve white thorn seed vigor, can remove seed dormancy because of it on the one hand, and it can regulate seed body internal hormone balance on the other hand; Low concentration gibberellin can improve the germination characteristic of white thorn seed, and excessive concentrations gibberellin then suppresses to sting in vain seed sprouting.

Described moss is that a group is small-sized, green, the higher plant of many cells, the differentiation of no vascular bundle, is the natural product resources bank of preciousness, not only can filter out the compound of higher pharmacologically active, can also filter out to promote crop seed to sprout and growth.

A kind of seed dormant method of white thorn of breaking of the present invention, its beneficial effect is: gibberellin has the effect of removing seed dormancy and regulating seed body internal hormone balance, contains the endogenous hormones that promotes seed germination in the moss leaching liquor; The present invention soaks the seed lukewarm water, with the liquor potassic permanganate seed soaking, makes kind of a skin attenuation then, increases the seed germination probability, and potassium permanganate has effects such as sterilization, deinsectization evil; Again seed is handled through gibberellin, moss leaching liquor, made that the white thorn seed time of processing is short, reduce time cost; And owing to use more natural plant seed germination promoter, improved white thorn active ingredient, satisfied its instructions for use; And emergence rate is neat, and it is strong that plant adapts to extraneous ability.
