Description
Technical field
The present invention relates to a kind of Japanese Rhus succedanea seed dewaxing vernalization germinating method, especially relate to a kind of hot-water dewaxing accelerated germination method for Japanese toxicodendron succedaneum seeds.
Background technology
Japan's Rhus succedanea is the long-term improvement of Rhus succedanea process that Japan introduces from China before more than 400 year, and the new varieties that cultivate are a kind of to produce the economic tree of lacquer seed, extraction haze tallow, have characteristics of many uses, that economic benefit is high.The haze tallow that is extracted is called " Japanese haze tallow ", and viscoplasticity is higher, has unexistent fine and smooth quality of general lacquer tree fat and sticking toughness, and melting point is up to 53-54 ℃, and than high nearly 10 ℃ of general lacquer tree fat, acid number only 4.5 is far below 30 of general lacquer tree fat.This haze tallow is present best in the world biological wax, is widely used in numerous areas such as military project, chemical industry, light industry, printing, health care, food, electronics, and the domestic and international market capacity is very big, and comparatively long-term and stable social demand is arranged.
Now, Japanese urbanization industrialization land used increases severely, and Japanese Rhus succedanea kind value area descends.
China is introduced into provinces such as Jiangxi, Hunan during the nearly last ten years and plants experimentally, and has succeeded, lays a good foundation for breaking international " Japanese haze tallow " market of Japan's monopolization.
Japan's Rhus succedanea lacquer seed kind skin has wax, and seed is hard, and is airtight waterproof again, and the seed dormancy that this mechanical obstacles causes is very big to the percentage of seedgermination influence.The lacquer seed is germinateed, must carry out dewaxing treatment to seed prior to seeding, remove the wax of the surface of the seed, seed could absorb moisture, expands to germinate.
At present, Japan and China generally adopt the concentrated sulfuric acid, potassium permanganate and washing powder to dewax, then with clear water seed soaking 30 days, sowing again.Test shows, use these methods, its nursery germination rate is respectively: germination rate only is 5.9% after the washing powder dewaxing treatment, with the concentrated sulfuric acid and potassium permanganate method of chemical treatment the germination of coating with lacquer seed then had obvious facilitation, its nursery germination rate can reach 25.4%-10.0% respectively, and concrete condition sees Table 1.
Table 1 dewaxing treatment is to the influence of percentage of seedgermination
But with concentrated sulfuric acid method dewaxing, very dangerous, operate careless slightlyly, easily human body skin and seed are caused burn.And use permanganimetric method, germination rate is quite unstable, though high germination rate reaches 24.7% sometimes, in most cases about 10.0%.

Embodiment
The invention will be further described below in conjunction with embodiment.
1, hot water dewaxing's roguing embodiment
" Japanese haze tallow " melting point that Japan's Rhus succedanea seed extracts is at 53-54 ℃.The hot water dewaxing then plants with the hot water bubble of 55 ℃-100 ℃ of water temperatures, and the wax of the surface of the seed becomes colloidal liquid by solid, could rub dewax with the hands with alkali; When using hot-water soak, not only high temperature has been killed germ, and owes full seed and can float the hot water surface when soaking, and is eliminated.
This test divides 5 processing by different water temperatures.Percentage of seedgermination is as shown in table 2.
Table 2 different temperatures hot-water soak dewaxing treatment is to the influence of Japanese Rhus succedanea percentage of seedgermination
Remarks: (1) is respectively handled seed weight and is 5kg; Hot water weight is 10kg; (2) after the cooling, seed is poured in the gunnysack, added soda ash 0.5kg and rubbed 30 minutes; 4. clear water seed soaking is changed water every day once; Soak after 16 days and dry; 5. make hotbed with the thick wet cow dung of 2cm, the thick 0.5cm of last lid layer left and right sides straw mulch film is put one deck toilet paper again, squirts, and puts seed again, uses plastic mulching, through 3 days, and when 1% seed sprouting is arranged, sowing immediately.
By table 2 as seen, take off curedly with hot water, can significantly improve Japanese Rhus succedanea percentage of seedgermination.At present, China's Jiangxi Province's growing area and Japan growing area Japan Rhus succedanea percentage of seedgermination are up to 25.4%, and the present invention, and Japanese Rhus succedanea percentage of seedgermination is 35-97%, for the former 1.38-3.82 doubly.
2, difference is rubbed the required time embodiment that rubs of method
Seed 5kg behind the taking-up hot water dewaxing, the gunnysack of packing into adds 0.5kg soda ash, tightens the gunnysack mouth with rope, with the hands catches gunnysack, pushing rubbing on the ground then; In addition heat-obtaining water dewaxing seed 5kg adds soda ash 0.5kg, use the hand rubbing seed on the floor, and the mensuration seed required time that is white in color sees Table 3.
Table 3 difference is rubbed France and Japan's this Rhus succedanea seed required time that is white in color
By table as seen, seed and soda ash are put into gunnysack rub, rub with the hands purely with empty-handed, not only the fast 1-2 of speed times, and both hands skin had protective effect.This is that burlap is coarse because gunnysack directly contacts with seed, and friction is big, wipes the surface of the seed wax easily.
3, different germination accelerating methods are to the embodiment that influences of Japanese Rhus succedanea percentage of seedgermination
Take 90 ℃ of seeds behind the hot water dewaxing, adopt hot poultry manure hotbed germination hastening method, electric blanket hotbed germination hastening method, hot water to drench kind of a germination hastening method, the vernalization of incubator germination hastening method respectively, measure germinating time and germination rate, the result shows: with hot cow dung, the vernalization of chicken manure hotbed, Japan's Rhus succedanea seed germinating time is 3 days, and germination rate is respectively 97%, 96%; The vernalization of electric blanket hotbed, germinating time are 2 days, and germination rate is 98%; Hot water drenches method, and germinating time is 3-5 days, and germination rate is 57%; Incubator vernalization, germinating time are 1 day, germination rate 99%; Details are referring to table 4.
Table 4 germination accelerating method is to the influence of Japanese Rhus succedanea percentage of seedgermination
Remarks: the vernalization fate of (1) " beginning germinating time " for beginning to germinate; (2) the insulation germination rate refers to the germination rate in the incubator; Germination rate after the germination rate of other germination hastening method refers to broadcast; (3) environmental temperature is bigger to the germinating time influence that hot water drenches method, and therefore, the beginning germinating time has 3-5 days fluctuation.
By table 4 as seen, it is the fastest that incubator method seed begins germinating time, only needs 1 day time, and all germinate in 1 day, and germination rate is up to 99%, but this method use has limitation, because of incubator vernalization, only is applicable to the situation that seed amount is less; In the production, the general quantity of vernalization seed is big, uses incubator vernalization, and efficient is too low; And incubator vernalization, though the percentage of seedgermination height, after planting, emergence rate is low.Use so the incubator germination hastening method only is suitable for the laboratory, be unsuitable for promoting aborning.Hot water drenches method, and is simple to operate, runs into fine day after the seed soaking and then germinate comparatively fast, and only need are 3 days, run into microthermal climate, and then germinating time is longer, and germination rate has only about 57%, so method is available in the south subtropics district, should not use in middle subtropical zone, north subtropical area.The electric blanket method, the beginning germinating time only needs 2 days, and clean hygiene, and is simple to operate, can use in place with good conditionsi.Make hotbed with hot brid guanos such as cow dung, chicken manures, the beginning germinating time needs 3 days, and germination rate reaches 96-97%, is very desirable germination accelerating method, is suitable for vast rural area and uses.
