Description
Technical field
The present invention relates to the production method of a kind of woody (arboreous) plant establishment cutting (cutting).Taking root for transplanting a cutting is meant the seedling that the scion of collection on breeding plant trunk forms, and is used for purposes such as large-scale afforestation.
Background technology
Be disclosed by on plant leaf surface, scattering the technology that the moisture-activated photosynthesis of plants be dissolved with carbonic acid gas improves plant products, for example, examine Japanese patent application 61-18131 number and the 08-84530 document in open.
Plant roughly is divided into woody stems the is arranged woody plant of (trunk (bark)) and the pliable and tough many slurries of acrial part but does not present the herbaceous plant of lignitoid.As everyone knows, usually, in the commercial nursery of woody plant, generally have by seedling that comes from seed germination formation and the clone nursery stock that obtains by cuttage, grafting or cell culture.Specifically, cuttage is a kind of most convenient and the technology that obtains clone nursery stock economically, for example in South America, ground such as Europe, Southeast Asia and South Africa use this technology to produce a large amount of eucalyptus to belong to the cutting of taking root of (Eucalyptus) and Acacia (Acacia) and be used for large-scale afforestation.
The prior art write up of the cuttage of taking root that belongs to about eucalyptus is in " eucalyptus domestication and breeding " (" Eucalypt Domestication and Breeding ") (K.G.Eldridge, J.Davidson and C.Harwood, 1993, New York:Oxford University Press Inc., 237-246.)
According to the instruction of the document, cut off 1-4 joint from the branch of elite stand, 2-8 sheet leaf, and blade-section removed with the preparation scion.This scion (Scion) is soaked in germicidal solution (as benomyl (Benlate)), and its base portion is coated with the hormone pulvis, (as the indolebutyric acid of root-inducing promoter) or soak in hormone solution, inserts then in the jack of cuttage medium.As the cuttage medium, the mixture of two or more in bark, sand, sawdust, bog moss, vermiculite, perlite, charcoal or these materials can use.Usually, the cuttage medium is placed on such as seedling-growing container or inserts in the container of dish (plug tray) etc.
Any material with suitable permeability and water retention capacity all can be used as the cuttage medium.The balance of permeability and water retention capacity is successfully taken root to scion and is played key effect.And, rotting in order to prevent scion, the cuttage medium should not comprise organic substance, and preferably will sterilize.Usually, although do not need fertilising, slow release graininess fertilizer can be sneaked into medium, or can add liquid fertilizer when irrigating.Because taking root, scion needs suitable temperature, high humidity and the air of circulation, therefore can be in conjunction with adopting spraying, atomizing, cover polyethylene film, shading and the technology of bottom heating.In order to bring better effect, the sunshine time that needed in every month is approximately 400 hours.
Yet, even use describe in the document of front through the cutting method of approval highly because multiple condition, as use the weather of this scion method country, so be difficult to usually guarantee that scion takes root.In addition, scion rootability is different with seeds.Even these seeds have strong rootability, because the various physiological factors of elite stand, scion also is difficult to take root.And, even prune elite stand and do scion, be difficult to also usually guarantee that scion takes root with the branch that its germinates.
Therefore, the rootability of scion depends on the meteorological factor of Production Regional or the hereditary factor or the physiological factor of scion to a great extent.Therefore,, be difficult to guarantee that scion has consistent rootability according to traditional scion method, thus the extremely difficult cutting of effectively taking root.
As a result, under many circumstances, the production that can only abandon taking root and transplant a cutting, this is the loss on the industry.Thereby, need a kind of scion production method that can effectively improve the scion rootability and keep the rootability unanimity.Especially the technology that needs a kind of effectively production large tracts of land afforestation to take root and transplant a cutting with eucalyptus genus seeds and Acacia seeds.
Japanese unexamined patent publication No. publication number 2001-186814 discloses a kind of method, comprise step: " preparation one usefulness the liquid medium moistening bed of taking root in insulating box; the medium cultivation is inserted in scion; and control the concentration of carbon dioxide in the insulating box ", and described, use this technology can improve the rootability of scion.
Yet, under the situation of afforestation,, also need the amount of growing seedlings (nursery stock) of 1000-10000 strain even under the situation of test, form industry, need the amount of growing seedlings of ten thousand strains more than 100.
Separating a large amount of like this scion in insulating box or culturing room, keep that simultaneously mobile carbonic acid gas is arranged in insulating box or the culturing room, is very difficult.
Purpose of the present invention just provides the method that a kind of production is taken root and transplanted a cutting, and this method can make scion take root high possibility, can be used for large-scale afforestation.Specifically, the invention provides the method for taking root and transplanting a cutting of a kind of woody plant of effectively production rootability difference.

The preparation method of the oxygen solution that in like manner, uses among the present invention is also without any qualification.First example of preparation oxygen solution methods is to produce O with contacting with water
2Material, for example peromag or calper calcium peroxide contact with water.Second example is to make O by little footpath perforated membrane or atresia Breathable films
2Thereby gas contacts with water making O
2Gas is dissolved in the water.And the 3rd example is that brine electrolysis produces O
2Gas also makes described O
2Dissolving.
According to the present invention, at least use a kind of taking root to promote the acrial part of the scion of liquid in being inserted in medium to spray off and on, the spraying number of times changes because of seeds and environmental condition, and this solution is selected from carbonic acid gas solution, oxygen solution, carbanion solution and bicarbonate ion solution.Therefore, use spraying without limits.Yet, as an example, can be from once selecting by per 10 minutes once a day.
The spray time that promotes liquid of taking root is set at by the described water that sticks on the scion blade face and begins to fall the required time, and the spray intervals of every kind of solution preferably sets the described required time of water evaporation on the plant surface of sticking to of serving as reasons.Spray time, common scope are 5-180 seconds.
And, promote the spray pattern of liquid not have particular determination to taking root.Yet, preferred usually spraying element such as the nozzle of using, spraying nebulizes.The average grain diameter that nebulizes is preferably in the scope of 10-100 micron.Thereby for example, carbonic acid gas solution can be evenly distributed on the blade face, and adheres to the form of fine drop, disperses to enter scion because of concentration gradient makes carbonic acid gas, promotes scion to take root.
Not concrete qualification of amount that scion is taken root and promoted liquid.But spray amount is preferably established at each single spraying element per minute 50-300cc.
In order to irrigate, this solution can be applied in the scion medium continuously, perhaps arrive several times once a day.That is, medium can be suitably moistening, perhaps above the medium some water can be arranged.
Describe the method that production of the present invention is taken root and transplanted a cutting in conjunction with following accompanying drawing with embodiment more specifically, wherein use membrane process to make carbonic acid gas solution and oxygen solution, offer scion, they are taken root.
Fig. 1 has shown an embodiment of the inventive method, and wherein, carbonic acid gas is dissolved in the former water to predetermined concentration, intermittently sprays to scion then.Fig. 1 shows the carbonic acid gas solution generator, and it is made up of the control valve SV2 of raw water vessel WT, booster P, filter F, membrane module MO, dioxide bottle 1 and upstream side, and the overall operation of generator is controlled by unshowned controller.
Raw water vessel WT is the container that holds former water, is used to produce carbonic acid gas solution.Although about not concrete qualification of kind of former water, it is economical that water is preferably wanted.
Booster P is used for providing above-mentioned former water to membrane module MO.Flow and flow velocity depend on the discharge capacity of this booster.In the present embodiment, the flow that provides is a per minute 1-1.5 liter.
Filter F is contained in the dirty of booster P, if necessary, is used for removing the contained particle of former water from booster P discharging.
Membrane module MO makes the former current that transmit from the upstream prepare carbonic acid gas solution through it as the membrane module that discharges air by supplying carbon dioxide simultaneously.Membrane module MO produces barometric gradient inside and outside film, can easily be generated the carbonic acid gas solution of predetermined concentration like this by former water.
And if when a part of water of handling in membrane module MO is got back to the entrance side of booster JN, this treated water can easily produce the carbonic acid gas solution with predetermined concentration by circulating.
By the carbonic acid gas solution that equipment shown in Figure 1 produces, compare CO with the carbonic acid gas solution that other method produces
2Concentration higher.For example, CO under 20 ℃ atmospheric pressure
2Solvability approximately be 1.78 (g/l water), this CO
2Concentration is the upper limit under the atmospheric pressure.On the other hand, according to equipment shown in Figure 1, by apply air pressure (1.1-5.0kgf/cm to membrane module
2), can make CO
2Be dissolved to the corresponding saturated concentration of this air pressure.
And equipment shown in Figure 1 not only can be used for preparing carbonic acid gas solution, also can be used for preparing oxygen solution, with the O that under atmospheric pressure is dissolved in the water
2Gas concentration is compared, and the oxygen solution for preparing by this equipment has higher O
2Concentration.For example, the O under 20 ℃ atmospheric pressure
2Solvability approximately be 44.3 (mg/l water), and this O
2Concentration is the upper limit under the atmospheric pressure.On the other hand, according to equipment shown in Figure 1, with top CO
2Solvability similar, O
2Can in running water (service water), be dissolved to and the corresponding saturated concentration of this air pressure.
In Fig. 1, the outlet of membrane module MO is connected with sprayer 6.In the normal operation, carbonic acid gas solution or oxygen flow of solution arrive sprayer 6 through the outlet of membrane module MO, spray to scion by the spraying element 61 that is installed on the sprayer 6.Sprayer 6 does not specifically limit with the distance of scion.As shown in Figure 1, sprayer can be installed in the top of scion and spray downwards, and is perhaps as described below, and it is installed in the below of scion, irrigates to scion.
As mentioned above, according to equipment shown in Figure 1, can in the extremely short time, produce the carbonic acid gas solution that under pressure, is dissolved in the predetermined concentration in the former water or the oxygen solution of any aequum continuously, and offer scion.
Among the present invention, the process that promotes scion to take root by above-mentioned carbonic acid gas solution (comprising bicarbonate ion solution and carbanion solution) is as follows: at first, and CO soluble in water
2Part becomes carbonic acid (H
2CO
3), carbonic acid ionization produces bicarbonate ion (HCO
3 -) and hydrogen ion (H
+).When carbonic acid gas solution offers scion, interior diffusion of unit interval and the CO that is absorbed by scion
2Increase with the amount of bicarbonate ion.Secondly, the bicarbonate ion that is dissolved in the scion is converted into CO rapidly under the catalytic action that extensively is present in the carbonic acid gas dehydration enzyme (carbonic anhydrase) in the plant
2As a result, the gas concentration lwevel in the chloroplast stroma and uprise as the substrate concentration of the ribulose diphosphate carboxylic acid of carbon dioxide fixation enzyme stimulates photosynthesis, thereby has improved the rootability of scion.
In addition, the mechanism of action that oxygen solution promotes scion to take root among the present invention is as follows: at first, when oxygen solution offered scion, oxygen concentration will be higher than in the atmospheric pressure oxygen concentration soluble in water under the partial pressure of oxygen.Then, form concentration gradient in and plant corpus periphery inner by the plant corpus of cellularity, oxygen diffusion as a result also enters scion.Scion obtains oxygen thus as earning a bare living energy needed.That is to say that NADH and FADH2 produce electronics, for example, glycolysis, fatty acid oxidation, or citrate cycle are given oxygen by the series electronic carrier transfer, generate ATP.Need the reaction of biopolymer biosynthesis or other energy to be achieved by combining with this ATP hydrolysis.The supply of oxygen has improved the synthetic of various biopolymers or has quickened other metabolism, thereby has improved the rootability of scion.
As for the photorespiration in the plant leaf blade, oxygen and carbonic acid gas are competed the matrix as the ribulose diphosphate carboxylic acid of carbon dioxide fixation enzyme, and suppress the reaction of other matrix mutually.That is, plant obtains light under the gaseous environment of high-concentration oxygen, and the photorespiration of plant can improve, and it becomes according to a floristic factor that reduces plant products owing to photorespiration.Thereby, to scion spraying oxygen solution,, or adopt method of irrigating oxygen solution to scion described below preferably in the dark period of illumination darkness.
Fig. 2 illustrates the example of irrigation method, and oxygen gas is dissolved in former water and reaches set concentration, obtains oxygen solution, intermittently irrigates to the scion medium.Although oxygen solution can offer the acrial part of scion, preferably offer the base portion cross section of scion.Example as shown in Figure 2, for implementing this method, oxygen solution is irrigated on supporting dielectric, like this, just can absorb oxygen solution from the base portion cross section of scion.That is, irrigation rig 7 is installed in the below of scion among Fig. 2.
