Description
Technical field
The present invention relates to the method for plant propagation, relate in particular to a kind of open fast seedling-cultivating method of light autotrophy of little seeds of a tung oil tree special use.
Background technology
How improved seeds and the clone seedling of all kinds of plants of fast breeding are the problems that people of all times extremely pay close attention to always.From traditional seminal propagation, division propagation, cottage propagation, propagation by layering, propagation by grafiting, to abt root-inducing powder, domestic and international various root-growing agents, clever root induction or the like the whole bag of tricks of taking root of plant test tube tissue culture, Wang Tao academician invention, human always at the biological breeding technique of Modern High-Tech of all kinds of plant improved seeds of innovation and development and clone seedling constantly.
At present, propagation methods such as test tube tissue-culturing quick-propagation, cottage propagation and propagation by grafiting are generally adopted in the vegetative propagation of the little seeds of a tung oil tree, these methods all have the common advantage of clonal reproduction: the better quality that can keep plant, but all there is shortcoming in these propagation techniques, the equipment investment of test tube tissue cultivating and seedling is too big, production cost is too high, is difficult to be applied.The plugged ear that cottage propagation needs is too big, becomes the seedling time oversize, and is seasonal strong, artificial poor controllability.Propagation by grafiting has the limitation in season, and when taking a lot of work, the production speed of emergence is slow, and is technical strong, can not batch production production etc. shortcoming.
What current little seeds of a tung oil tree industry generally adopted is seed seedling-raising, because little seeds of a tung oil tree seedling belongs to sexual propagation, must just exist the kind hereditary variability big, the fine-variety breeding of excellent strain is very difficult, output is very low, quality does not have guarantee, and the expection of bearing fruit and getting bumper crops is not had shortcomings such as artificial controllability.Maximum difficult point is because little seeds of a tung oil tree plant is half carnification Euphorbiaceae woody plant, its root, stem, bar, branch, leaf, bud all contains a large amount of protein type milk, the bacteria breed breeding is exceedingly fast, the in-vitro propagate material that causes the little seeds of a tung oil tree very easily wound rots, cause the inefficacy of taking root of the callus of little seeds of a tung oil tree in-vitro propagate material or plugged ear, survival rate is very low, so the Plant Tissue Breeding of the little seeds of a tung oil tree or other non-test tube clone fast seedling growing difficulty are very big, both at home and abroad basically can't the little seeds of a tung oil tree clone of large-scale production breeding seedling.The above is exactly the real before this situation of little seeds of a tung oil tree industry.
Summary of the invention
The present invention is too big for the seed seedling-raising hereditary variability that solves the little seeds of a tung oil tree, and quality does not have guarantee; Other clonal reproduction again complicated operation or breeding difficulty, be subjected to seasonal effect big, production cost height and speed of production wait technical problem slowly, have proposed the open fast seedling-cultivating method of light autotrophy of the little seeds of a tung oil tree special use of a kind of efficient, practicality, low cost, high benefit, high-speed, high-quality, easy batch production production.
The open fast seedling-cultivating method of light autotrophy of the little seeds of a tung oil tree special use that the present invention proposes, its step is as follows:
Step 1, by clip plant plant material on the maternal plant;
Step 2, plant plant material is trimmed to plugged ear;
The soup of step 3, plugged ear is handled;
Step 4, plugged ear is inserted the seedbed;
Step 5, plugged ear is carried out moisture spray;
Step 6, plugged ear is carried out disinfection;
Step 7, plugged ear is imposed rich water;
Step 8, outplanting are transplanted.
Why vegetative propagation can be successful, is because each living cells of plant all comprises the necessary full gene that grows, totipotency that plant cell shows in inheritance that Here it is.That is to say: the cell division of higher plant, can both keep any one potential ability in their heredity, make the stripped part of the plant with labyrinth, produce through the breeding of cell multiple division and be same as maternal each several part tissue and organ.This provides strong proof for the plant cuttage breeding.Test tube tissue-culturing quick-propagation, cottage propagation and propagation by grafiting and even the technology of the present invention (the open fast seedling growing technology of light autotrophy) commonly used at present all are to have used above-mentioned principle.
The open fast seedling growing technology of light autotrophy is developed rapidly aspect growing seedlings in little seeds of a tung oil tree clone, utilize this theory exactly, the spray plugged ear of little seeds of a tung oil tree plant is cultivated and the identical Jatropha curcas plant of maternal inheritance information under aseptic and conditions such as the material that helps to take root, illumination, temperature, moisture, air.
The open fast seedling-cultivating method of little seeds of a tung oil tree light autotrophy is with the similar test tube stem of a leaf one bud section of the little seeds of a tung oil tree, the micropropogation material unit of Shoot Tip Culture, directly be seeded in after with growth substance " leaf one bud " material cut being handled and auxiliaryly have the husky bed in land for growing field crops of simple and easy condition to go up (can be modern facilities agricultural grow seedlings or use the Seedling bag container nursery), under aseptic and conditions such as the material that helps to take root, illumination, temperature, humidity, moisture, air, make the stripped material of the little seeds of a tung oil tree cultivate and the identical Jatropha curcas plant of maternal inheritance information.After the second generation, just can obtain the complete Jatropha curcas plant of regenerating in 7-20 days, and survival rate is up to 80% to 100%.Every 20-60 days breeding generation can be by the geometric progression high efficiency quick breeding.Reproduction coefficient reaches more than the 2-15, faster numerous coefficient height than in vitro.Under the simple and easy condition of leaving plant test tube tissue culture fully, realized the high efficiency quick breeding that this plant species of the little seeds of a tung oil tree just may reach under the test tube condition.
The open fast seedling growing technology of little seeds of a tung oil tree light autotrophy is through throughout the country as various climatic zones, continuous 6 years research, test, exploitation, production, the popularizations of various soil such as Hainan, Yunnan, Sichuan, Guizhou, Guangdong, Guangxi, having formed a complete technical system, is a very ripe plant efficient clone quick reproduction technique technology.Owing to thousands upon thousands ordinary persons through technical training are directly implemented in the field, strengthened the easy biography and the popularity of little seeds of a tung oil tree fast breeding technique; Strengthened actual comprehensive fast numerous efficient, (one-time investment is lower tens times than tissue culture rapid propagating technology to have reduced the production cost of little seeds of a tung oil tree factorial seedling growth to greatest extent, perfect whole shortcomings that overcome little seeds of a tung oil tree test tube tissue-culturing rapid propagation and little seeds of a tung oil tree conventional seedbed system technology dexterously, and keep and the whole advantages of the two of having brought into play them).Production returns of investment ratio can reach 1: 3--1: more than 8.It saves little seeds of a tung oil tree plant germplasm material very much, only begin breeding with the miniature material of little seeds of a tung oil tree plant one leaf, one bud, to 100 strain Jatropha curcas plants if from first month, take 2 propagating materialss in every month and produced 12 months continuously, just can breed 312 * 100=53144100 strain even the purebred seedling of more than one hundred million strain in 1 year
The technology of the present invention is compared with traditional seedling growing process with plant test tube tissue-culturing rapid propagation, has following advance and novelty:
1, reduced investment.The small-scale production of year breeding 500,000 seedlings, the facility of investing about thousands of units just can start.
2, survival rate height.With the stripped material of a leaf one bud plant is the breeding unit materials, directly is seeded in booth seedbed or the nutritious bag, and once-seedling forming is produced until supply, does not need any moving.Container seedling is a trend of implementing the International standardization cultivation, and container seedling has been broken the season limit of nursery stock sale, transplanting: can sell at any time, can be transported to the destination at any time at a distance and transplant.
3, take root soon, become seedling fast.The speed of taking root into seedling surpasses the training of test tube group, takes root, can become seedling in 20 days in many plant 7-10 days.
4, be not subject to seasonal restrictions, 365 days any time all available these fast breeding techniques start production in 1 year, have expanded time and space that technology is used.As long as just can grow seedlings at little seeds of a tung oil tree vegetative season, with good conditionsily can use heat preservation greenhouse, 1 year 4 season can emerge.
5, numerous seedling coefficient height.The sum of little seeds of a tung oil tree nursery stock becomes geometric progression constantly to double.Most little seeds of a tung oil tree plants after the second generation, each little seeds of a tung oil tree regeneration plant breeding in every 30-60 days generation, per generation growth coefficient be 2-15 doubly (on the little seeds of a tung oil tree plant of original seed quantity radix by the geometric progression high efficiently multiplying).This point is had a competition, and to cultivate fast numerous advantage also outstanding for tubing.To the algebraically of back, the germ plasm resource material of breeding is many more more, and the speed of breeding is fast more.
6, extensive applicability.Study up to the present, except that the little seeds of a tung oil tree, this technology can make most of plant establishments, and some adopt the still irreproducible plant of test tube groups training, but can breed well with the technology of the present invention; Many plants can not be adopted conventional cottage propagation, and the technology of the present invention is fast numerous to make the good rooting propagation of most of plants and adopt.This technology can be widely used in industries such as flowers, nursery stock, fruit tree, vegetables.
7, production cost is low, and technical step is few.The used time is short, has greatly saved comprehensive production cost and has improved personnel's production efficiency.Begin breeding from miniature material, can directly cultivate the plant of growth under field conditions (factors), do not need any transplanting.The cultivation that most plants are only needed 15-60 days promptly can be used for producing cultivation, and plant all shows and yield positive results early, and yielding ability is good.
8, threshold is low, need not the professional.Common peasant need not professional knowledge and also can learn operation, and grasp speed is fast, and the technology processing ease is promoted.Can inoculate 3000--10000 unit materials through training qualified unskilled labour power every day (8 hours) after a while.The long-term popularization facts have proved: the one, and less demanding to the production technology peopleware, the technical training phase is short, adaptability is extremely wide, is easy to promote; The 2nd, individual service speed is all faster than tissue culture quick breeding and conventional seedbed system, proper as organization and administration, under the situation that other conditions satisfy, every day, each base can inoculate 200,000 fast--1,000,000 unit propagating materialss, technology is easy to large tracts of land and promotes, and this is that the tube rapid propagation technology is incomparable.
9, the ordinary person through one section of planned training can participate in fast numerous operation element, inoculation speed is exceedingly fast and (surpasses several times of test tube tissue-culturing rapid propagation inoculation speed, both surpass the conventional seedbed system service speed from the most plants of the second generation, also surpassed the service speed of tube rapid propagation.Greatly saved the labour expenses and improved efficiency).
10, but each is through one section every month production management 5-30 ten thousand young plant wood of skilled worker that training is qualified, and each backbone adds that the underworker of some can produce 3,000,000 strain seedling every half a year at least, and the wound economic benefit is high.

12, the technology of the present invention can be used for most once using fast numerous plant and the fertile plant of normal cutting propagation seedling growing process of plant tissue culture stem apex, or above-mentioned two technology all are unsuitable for the plant that breeds; Can be used for hybrid vigor fixing in the plant breeding work; Can be used for extraordinary genetically modified plants grow seedlings fast numerous popularization and protection, forest seedling growth, seed engineering and the Seed Industrialization of engineering, space breeding new plant, various new germ plasm materials or economic plants in imminent danger; Can be used for the clonal selection purifying of spontaneous mutation plant, fine individual plant and polyploid dominant strain and a large amount of production utilization; The isolation that can be used for virus-free former seedling is expanded numerous; Can be used for domestic and international new varieties and introduce a fine variety diffusion, crossbreeding or the like.The optimality that possesses skills of this patented technology and the extensity in market in these areas.
Embodiment
Be the open fast seedling-cultivating method of light autotrophy that embodiment describes the little seeds of a tung oil tree special use of the present invention's proposition in detail with the little seeds of a tung oil tree below, its step is as follows:
Step 1: by clip plant plant material on the maternal plant of the medium and small seeds of a tung oil tree in material garden (maternal plant garden).
(1) if maternal plant needs to cultivate into certain tree type simultaneously, tries not to influence the cultivation of tree type during clip;
(2) if maternal plant just for propagating materials is provided, then when beta pruning, to stay at least one more than the axillalry bud to allow maternal plant can continue germinating growth;
(3) some plant needs that are difficult to take root is handled maternal plant in advance;
(4) the material garden can not be too far away far from the distance in seedbed, fresh easy more the taking root of the material of growing seedlings;
(5) material of the plant plant of clip will be noted preserving moisture, and is placed in the plastic sack or bucket of sealing as far as possible, and avoids strong illumination.If remote transportation will prevent material heating or air-dry dehydration.Note fresh-keeping, preserve moisture and be incubated.
Step 2: the plant plant material of the little seeds of a tung oil tree is trimmed to plugged ear
(1) plugged ear of general plant is as long as a leaf one bud (leaf and an axillalry bud) saves the best down stem section that 3～5cm is arranged so that cuttage.If plant plant material is less, can be split into 2,4 with joint is vertical with blade for some plants, in addition more a plurality of as plugged ear.Tissues such as blade of some plants or root system can be used as plugged ear, also can take root into seedling in this seedling system;
(2) short for the plant internode, can be cut into the long many leaf stem sections of 2～3cm, keep 1～2 blade in top, cut off lower blade and petiole;
(3) for the blades of some plants can a clip part as plugged ear;
(4) plugged ear that shears can not be air-dry, should in time enter next step processing or water spray keeps moistening while cutting.
Step 3: the soup of plugged ear is handled, and can adopt following two kinds of methods:
Method 1
7.5～12.5 kilograms of the carbendazim aqueous solution that preparation earlier is 700 times are about in the water that 25 gram carbendazim add 12.5 kilograms; Take by weighing 2.5～5.5 gram growth promoters again and add absolute ethyl alcohol 100～250 grams, add 1～2.5 kilogram in water after dissolving, fully pour the carbendazim aqueous solution into after the dissolving and fully stir into admixing medical solutions.Also can be earlier melt described growth promoter, use behind the dilute with water again with 40 ℃ of warm water of 1～2 kilogram.
At last plugged ear is poured into and soaked in the described admixing medical solutions 10～60 minutes.Evergreen plant was soaked 60 minutes, and deciduous plant was soaked 10-30 minute.
Perhaps
Method 2
The powerful growth stimulator of preparation 100 grams with pruning good plugged ear two otch, dips in toward powerful growth stimulator middling speed respectively earlier, the plugged ear otch is adhered to evenly get final product.
Prepare the growth promoter of 1000 grams again.The lower end otch that dips in the plugged ear of powerful growth stimulator is dipped in standby getting final product toward the growth promoter middling speed.
Growth promoter is formulated by following pulvis component: D-arabo-ascorbic acid one 130 grams, acetylsalicylic acid 130 grams, phenacetin 125 grams, sulfamethoxazole 200 grams, Trimethoprim 40 grams, heteroauxin 250 grams, Nafusaku 250 grams.Above pulvis is all sneaked in the special container, fully stir with artificial or machinery, attention must be stirred very evenly, and the finished product that stirs after finishing is growth promoter.This growth promoter is insoluble to the normal temperature clear water, is soluble in absolute ethyl alcohol or acetone.The working concentration that little seeds of a tung oil tree plugged ear speed is dipped in method is 2000PPM, promptly takes by weighing this growth promoter 2 grams, in the absolute ethyl alcohol or acetone of going into 100 grams, after stirring abundant dissolving, adds 900 gram clear water again and stirs, and then can begin the cuttage step of little seeds of a tung oil tree plugged ear.
Described powerful growth stimulator is the powerful growth stimulator of the little seeds of a tung oil tree micropropagation plugged ear special use that is mixed with of the pure Chinese medicine of a kind of usefulness.Because little seeds of a tung oil tree seeds are half carnification Euphorbiaceae woody plant, its stem, bar, branch, leaf, bud all contains a large amount of protein type milk, the bacteria breed breeding is exceedingly fast, the in-vitro propagate material that causes the little seeds of a tung oil tree very easily wound rots, and causes the inefficacy of taking root of the callus of little seeds of a tung oil tree in-vitro propagate material or plugged ear, so the Plant Tissue Breeding of the little seeds of a tung oil tree or other non-test tube clone fast seedling growing difficulty are very big, survival rate is very low, both at home and abroad basically can't the little seeds of a tung oil tree clone of large-scale production breeding seedling.Normal cutting propagation exist again take root slow, survival rate is low.Conventional grafting exists technology numerous and diverse again, and professional skilled worker is few, and the improved variety scion rareness causes the nursery stock of this kind using seminal propagation always, and offspring's character variation is very big, and the product fruit of the Jatropha curcas plant of growing up is very low, and per mu yield is super so far only more than 200 kilograms.The above-mentioned various technical barriers that the technology of the present invention is grown seedlings at little seeds of a tung oil tree breeding, innovation goes out a kind of powerful growth stimulator of little seeds of a tung oil tree micropropagation plugged ear special use of pure traditional Chinese medicine ingredients, result of use good (survival rate of little seeds of a tung oil tree plugged ear reaches more than 95%), use cost low (the agent in about 1 minute of the little seeds of a tung oil tree seedling of every strain), use instant effect (little seeds of a tung oil tree plugged ear with agent then under the booth condition, got final product healing and taking root in 7-15 days), use most convenient (little seeds of a tung oil tree plugged ear otch dip in get final product) with the agent middling speed.So, the technology of the present invention with regard to successfully solved at present both at home and abroad basically can't the little seeds of a tung oil tree clone of large-scale production breeding seedling the technical bottleneck problem.
Step 4: plugged ear is inserted the seedbed
The plugged ear of handling through soup is picked up, insert successively and prepare in the appropriate medium of seedling bed (as peat, grass meal, perlite, vermiculite, fine sand, yellow soil etc.), blade size according to plugged ear, but general every square metre of cuttage 300～1500 strain plugged ears, even more, be not advisable so that the blade of plugged ear is overlapped.Medium of seedling bed just plays the effect of immobilization material in this seedling system, so the plugged ear insertion need not too dark.
If the plugged ear quantity of a cuttage is bigger, the time of cuttage is longer, on one side then cuttage is on one side sprayed water, here does not wither to keep blade.
Step 5: plugged ear is carried out moisture spray
Plugged ear organize do not take root before, do not have root system to absorb the transpiration that moisture replenishes blade, should increase the balance that blade face moisture and air humidity make the cell maintenance moisture in the blade this moment by foliar spray.
Can adopt following several method respectively:
(1) artificial spray-on process.According to external environment, use sprayer that the plugged ear tissue is sprayed in good time.once grow seedlings below 60,000 strains or labour's cheap situation relatively more than needed under can use this method.
(2) the electronics instrument auto spraying method of growing seedlings.According to the gear that chooses, the electronics instrument of growing seedlings was automatically controlled 2～30 minutes auto sprayings in every interval about 5～30 seconds, need not the manual control switch.
(3) intelligent computer auto spraying method.By computer, equipment such as controller and hygrosensor carry out the intellectuality spraying.
Step 6: plugged ear is carried out disinfection
Before plugged ear formed callus, otch might in order to stop bacterial infection, generally every 4～5 a days spray carbendazim aqueous solution (800 times), or be imposed other specific aim bactericide by bacterial infection, treats to stop to spray medicine after the plugged ear tissue begins to take root.The time of spraying liquid should stop to allow plant tissue fully absorb on the blade so that soup adheres to after the water spray between the lights.
Step 7: plugged ear is imposed rich water
Before the cuttage rooting, every one time 0.2% potassium dihydrogen phosphate aqueous solution of spray in 5～7 days, aqueous solution of urea or composite fertilizer's aqueous solution of spray in per 5～7 days a time 0.2～0.5% behind the cuttage rooting.
Step 8: the little seeds of a tung oil tree outplanting that will grow up to is transplanted
Transplanting be grow seedlings a most critical in the link and the technology of easy ignorance.Having grasped transplantation technique can make the survival rate of nursery stock near 100%.
The technical key point of transplanting method; At first must grasp the core rule of a plant transplantation, it is vital all must keeping the measure of good coring moisture behind any plant transplantation; Next is that the coring fracture wound that impels plant to cause in the transplanting process of being unearthed heals rapidly, and continuous as early as possible long new root also is the key of transplant survival.Transplanting method has the following steps:
1, before 3 days after the decision little seeds of a tung oil tree outplanting that will grow up to is transplanted, no matter be plant seedling or container seedling, all should be careful water one time permeable, transplant the same day once with the growth agent solution foliage-spray of 100PPM, just can begin lifting.
2, behind the lifting,, also can transport for long-distance and transplant to the destination if the mug that can cuvette changes of container seedling continues cultivation on the spot.But if plant the bareroot seedling that the seedbed trips out, just must the root system that each little seeds of a tung oil tree are exposed soak uniformly and wrap one deck yellow mud, shipment is sent to the destination again, this is a vital ring to the high-servival rate that guarantees little seeds of a tung oil tree large tracts of land afforestation.
3, plant seedling or container seedling the above-mentioned little seeds of a tung oil tree, after shipment is sent to the destination, must soak into a yellow mud pulp-water (container seedling is promptly soaked i.e. kind after need taking off cup) uniformly again by immediately that each little seeds of a tung oil tree are exposed root system, open the hole according to little seeds of a tung oil tree afforestation standard and plant just passable.
4, finish by rules plantations after, creating conditions as far as possible irrigates normal root water, so little seeds of a tung oil tree transplantation of seedlings survival rate generally can be near absolutely.
5, the preparation of yellow mud, in the growing area hole of about one meter of digging diameter on the spot, take as far as possible stickiness preferably yellow soil put into the hole, add water and stir into mud, can also flow after stirring evenly is as the criterion; The per 10 kilograms of growth promoters that contain 1 gram of the water that adds, this growth promoter dissolves fully with 1～2 kilogram of clear water earlier, again in after the described ratio preparation to going in the mud, stir fully, can begin the little seeds of a tung oil tree and soak root and wrap up in the slurry operation.Finish the little seeds of a tung oil tree coring of each strain successively and soak the operation of wrapping up in mud, plant successively again in the plantation of having opened up wasteland hole and get final product.
The clone of the little seeds of a tung oil tree is grown seedlings and is selected container cup to grow seedlings as far as possible, because container seedling is a trend of implementing the International standardization cultivation, container seedling has been broken the season limit of nursery stock sale, transplanting, can sell at any time, can be transported to the destination at any time at a distance and transplant.The technology of the present invention is applicable to growing seedlings of plants such as all flowers, nursery stock, fruit tree and vegetables.
