Description
Technical field
The present invention relates to the planting technology of a kind of agricultural or livestock breeding, the present invention relates to exactly abolish the strong method of seed in the leguminous plant plantation.
Background technology
Strongly extensively be present in the leguminous plant.Because densification kind skin or pericarp that seed has have suppressed seed germination thereby can hinder moisture absorption.Having that seed is strong is beneficial to the soil seed bank, soil seed pool preservation, population continues and the storage of germ plasm resource, but then, strong to agricultural production practice bring seedling planting difficulty, the problem such as irregular of emerging, seed is carried out the important measures that presowing treatment is strong to abolish, breaking dormancy is agricultural production.
Have multiple hard crust of legume seeds to abolish method in the prior art, its main way is to utilize the means of physics or chemistry to strengthen kind of the saturating property of skin, impels the seed suction, thereby breaks seed dormancy.Physical method is to abolish strong effective method the most at present, its common way is to damage the purpose that kind of skin reaches enhancing kind of the saturating property of skin by mechanical treatment, but the time-consuming consumption power of the method, in the only suitable laboratory small quantities of seed is handled, can not satisfy the extensive needs of handling seed in the production practices, the seed less for some volumes then easily damages, and can't use mechanical means to handle basically.Chemical method such as acid etching or alkaline etching also are strong one of the processing means the most commonly used of abolishing, and its main method is that seed is immersed in certain density acid or the alkali, after processing a period of time, with the unnecessary acid solution of a large amount of flushing with clean water, dries.Although the method can be carried out batch process to seed, need a large amount of soda acids, processing cost is higher; It two will adopt a large amount of water to wash after handling, and can cause certain pollution to environment on the one hand, and the imbibition that seed in this course can be in various degree causes the imbibition injury on the other hand, and seed moisture content is increased, and is unfavorable for storage; In addition, the surface of the seed after acid or alkaline treatment still can residual a spot of acid or alkali lye, directly has influence on the emergence rate or the growth of seedlings of seed.Many methods of existing report are breaking hard crust of legume seeds effectively, but only limits to mostly use in the laboratory, is not suitable for large-scale production practices needs.
Chinese invention patent application 200810017529.9 discloses a kind of method of stopping clover seeds dormancy in hard seeds, this method adopts inoculation mould, aspergillus oryzae or Trichoderma viride, the perhaps combined treatment alfalfa seed of above-mentioned bacterial classification, solved the problem of stopping clover seeds dormancy in hard seeds, but this method is handled some kind skins or harder or closely knit its effect of seed of pericarp quality is non-constant.Therefore, seek a kind of economic and practical, non-environmental-pollution, can abolish the strong method of seed on a large scale and have great importance for the cultivation utilization of pulse family germ plasm resource.
Summary of the invention
The invention provides and a kind ofly can overcome the prior art deficiency, can abolish effectively seed strong, can at utmost protect seed not come to harm simultaneously, make it that strong method of seeds of leguminous plant of abolishing of higher emergence rate be arranged.
Method of the present invention is earlier the pending seed and the concentrated sulfuric acid to be mixed thoroughly, place after 30～180 minutes acid solution with seed water flush away surface, again seed is put into alkaline salt or abundant stirring of aqueous alkali that mass ratio is 5% concentration and carried out neutralisation treatment, non-foam produces in water, pull the seed cleaning of blunging out, pull out and dry, cleaning process and neutralisation treatment process should be finished in 10～20 seconds.During the invention process: seed and concentrated acid liquid are mixed the time length of placing the back thoroughly and are determined according to seed strong thickness and compactness extent, its basic requirement be make strong fully by the acid effect, be not subjected to sour effect and be in strong interior material, as handled Bai Sanye seed in the embodiment of the invention, it is 30～60 minutes that seed is mixed the time of placing the back thoroughly with acid; Water-washing process after acid treatment and alkali N-process require only to make the acid in strong to be washed out and neutralize, and do not make the material suction in strong or have an effect with alkali.
With Bai Sanye is example, and preferred the employing mixed the per kilogram seed thoroughly in the method for the present invention with 50 milliliters concentrated sulfuric acid acid; Preferred simultaneously use potassium hydroxide or potash carry out neutralisation treatment.
The present invention has following advantage:
1) because the present invention adopts bronsted lowry acids and bases bronsted lowry to unite seed is handled, can avoid in the prior art single employing acid or alkali to handle, cause seed by the deficiency of acid or alkali injury.
2) because immersion treatment in the acid solution is simply immersed seed in the present invention, but only the seed and the concentrated sulfuric acid are mixed thoroughly, made acid only act on the epidermis of seed, this has just further lowered the detrimental effect of concentrated acid to seed.
3) seed treatment time of determining of the present invention, because the time compole that seed contacts with water is short, thereby seldom imbibition of seed, its water content can be controlled at minimum level, this has just overcome the imbibition infringement that seed causes owing to suction in the prior art processing procedure, or cause its water content to increase, be unfavorable for the deficiency of seed storage.
4) the present invention is owing to fully neutralize through alkali lye, and seed is not having adhesion between individuality after the cleaning, is convenient to sowing, and no prior art is handled the serious deficiency of back seed adhesion.
5) the present invention is preferably with potassium hydroxide or potash, not only can be effectively in and concentrated acid, and residual potassium can also help plant growth as potash fertilizer.
In addition, show that adopt method of the present invention to handle seed, its emergence rate is higher than the emergence rate after prior art is handled same seed through relevant test.
Description of drawings
Accompanying drawing is that distinct methods is handled back seed germination rate, blind seed rate and hard seed rate figure, abscissa is a method for treating seeds among the figure, wherein: " control group " is strong for not adopting any measure to handle, and " soda acid composite algorithm " carries out strong processing for adopting method of the present invention; Ordinate is a seed percentage.
Embodiment
A specific embodiment is provided below the present invention:
The seed that present embodiment is handled is a leguminous plant Bai Sanye seed.
This plant species of Bai Sanye can be abolished the Bai Sanye seed dormancy preferably with mechanical treatment, but, mechanical means such as cut by frosted or cutter and easily embryo is caused damage, as the frosted overlong time because the Bai Sanye seed is less, or cutter to cut the position inaccurate, thereby cause that blind seed digital display work increases; Mechanical treatment is wasted time and energy on the other hand, is difficult to use in the mass disposal seed, thereby has limited its application in production practices.If by prior art, it is the germination rate that can significantly improve the Bai Sanye seed after processing a period of time that the Bai Sanye seed is immersed concentrated sulfuric acid solution, but because the Bai Sanye seed is less, plant skin-deep to thinner, can cause part seed blackout after general the processing and cause death, the blind seed rate is up to 26% in the Comparative Examples of present embodiment; In addition, handle the back seed and need use a large amount of flushing with clean water, on the one hand environment is polluted, also cause quite a few seed in this process imbibition on the other hand, cause the imbibition infringement, or cause its water content to increase, be unfavorable for seed storage, and the seed behind the Hui Gan sticks to each other together, although can obtain better result in the laboratory, operability is relatively poor aborning.
Processing method of the present invention is as follows:
At first use acid etching, press the amount of the per kilogram seed 50ml concentrated sulfuric acid (98%), seed is fully mixed thoroughly, the Bai Sanye seed generally stirs and got final product in 30-60 minute.
Cleaning treatment is prepared two big basins, contains clear water, and seed is placed clear water, promptly pulls out after doing stirring slightly, seed is placed second clear water basin to stir again.Whole process will be finished fast, about 10 second time, detect the pH value of water in the basin in the test at any time, and its pH value remains on more than 2.
The alkali neutralisation treatment, prepare a big basin, fill 5% potash (also can use potassium hydroxide) solution, seed behind the mistake water is placed alkali lye, fully stir, produce until non-foam, this process should not surpass 10 second time, the same pH value that detects alkali lye in the basin in process of the test of the present invention, its pH value is greater than 8.
Last cleaning treatment is prepared a big basin, contains proper amount of clear water, after will being placed in one through the seed of neutralization reaction, mixes slightly, pulls out to dry to get final product, and keeps water transparent, to guarantee seed quality is preferably arranged.
Through seeds treated germination rate of the present invention is 86%, and the blind seed rate is 3%, and hard seed rate is 11%; And it returns dried 24h through nature or with after the drying plant oven dry, seed moisture content is 6%.The contrast of the present invention and prior art is handled germination rate, blind seed rate and hard seed rate figure behind the seed referring to what Fig. 1 provided with distinct methods.
By accompanying drawing as seen, after method of the present invention was handled, the Bai Sanye seed can make its germination rate be brought up to more than 86% by 40% before handling, and it is neat to emerge, and does not cause that the blind seed number obviously rises.Simultaneously, because the time compole that contacts with water owing to seed in the processing procedure of the present invention is short, thereby seldom imbibition of seed, handle with seed pelleting Pelleting oven dry process equipment (Nanjing Tianyu Machinery Co., Ltd.'s manufacturing) again through seeds treated of the present invention, its water content is 6%, and visible seeds treated of the present invention is less to the influence of storage.Owing to fully neutralize through alkali lye, seed is not having adhesion between individuality after the cleaning in addition, is convenient to sowing.Adopt method of the present invention successfully to handle the Bai Sanye seed of 24 tons of high dormancy rates, can determine that thus the present invention has the value of applying aborning.
