Through above-mentioned simulated weightlessness methods for the treatment of seed and device do three-dimensional spin breeding handle (handling) hereinafter to be referred as three-dimensional spin breeding 40 surplus the seed of a kind growing seedlings the stage and after whole growth grow, the feature of growing seedlings with vegetative period than conventional breeding in the maturing stage has evident difference.Most seeds show the remarkable advantage of germination rate height, growth cycle weak point, well developed root system, output raising in the course of cultivation.Its reason is:
1, the seed inside of sprouting period is in state very active in its growth cycle; physics to external world, the change of chemical environment are very responsive; the marked change of environmental condition (referring to the variation of physical environment here) will cause the marked change or even the sudden change of the inner biological motion rule of seed.
2, make the seed of sprouting period be in the suspended state of quick spin, when spinning fast (the tens of commentaries on classics of per minute), seed can't produce " memory " to specific gravity direction and light source direction, that is to say: the seed of budding period is before the direction of experiencing gravity and source stimulating, the direction of gravitational field and light source field changes, with unidirectional multidirectional of becoming biologically of normal presence.At this moment, the root system of budding period seed can't be followed along the rule of specific gravity direction growth, the bud seedling also can't be followed along the rule of light source direction growth, and they all are in the open growing environment of no fixed-direction, and this environment helps to grow more strong, plentiful coring and bud seedling.
When 3, the seed of sprouting period spins under the effect of solution, there is rubbing action between the epidermis of seed and the seed-soaking liquid, epidermis to seed is massaged, the massage effect of this fluid makes that the inner more growth enzyme of seed is activated rapidly, thereby improved germination rate, accelerated the speed of growing of rudiment.
When 4, the seed under being in the embryonic stage was in the suspended state of quick spin, the direction of the centrifugal force that produces in the spin process was consistent with the biological force direction of bud seedling growth, so it helps the growth of bud seedling and root system.
5, the experiment of experimental group and control group shows: simulated weightlessness methods for the treatment of seed and device can impel embryo organ more morning, growth quickly.The thick base of polarity and root or leaf early appearred in two days in experimental group than control group, even the plantlet blade that produces also can earlier form chlorophyll in the illuminance of experimental group under only for half condition of the illuminance of control group, experimental group has longer, more plentiful coring and higher output than control group simultaneously.
A series of breadboard grow seedlings and warm canopy cultivation contrast experiment proves: to being in the seed of sprouting period, (seed is subjected to gravity and hydrokinetic effect in the rotation incubator because of the change of physical environment, seed is suspended in the dynamic equilibrium district do free motion in the solution and does not float or sedimentation), to seed sprouting with the growth of ensuing crop obvious facilitation is arranged.
Basic principle of the present invention is:
1, seed utilizes the motion that moves both vertically and swing that produces with joint efforts of circular motion, gravity and the buoyancy of fluid dynamic generation, make seed dynamically be suspended among the solution, seed is constantly done three-dimensional spin motion at random in solution, concerning the histoorgan of seed inside, gravity direction is at random, on all directions of seed, the integration of gravity and time goes to zero.Seed dynamically is suspended among the solution, and key is the control to the container rotary speed, and it is different and different with size, the proportion of processing seed.
2, the announcement of stress-growth relationship is the most important discovery of 20th century biomethanics.Animal and plant all is suitable for.In three-dimensional spin breeding treating apparatus, there is relative motion between seed and the solution, the shear stress that flows will change the growth conditions of seed in the surface of the seed of sprouting.
Change the basic understanding that crop breeding is influenced according to above-mentioned physical environment, utilize simulated weightlessness methods for the treatment of seed of the present invention and device, divide three phases that all kinds of plant seeds of more than 40 kinds are carried out three-dimensional spin breeding processing experiment, research has obtained beat all gedanken experiment result.

2. " Ai Decheng " grass
Bigger than the control group variation with the experimental group of " Ai Decheng " seed of 48 hours of 100 rev/mins of processing through three-dimensional spin breeding under 25 ℃ of conditions, germination rate improves more than 40% than control group, and bud seedling growing way is faster.
Above-mentioned grass seeds experimental data proves: the percentage of seedgermination height of experimental group, well developed root system, fast growth.The exploitation of this technology and use and will afforestation vegetation, the protection ecological balance in the western provinces area of drought and water shortage be had great importance.Because its germination rate, survival rate height, fast growth can improve the plantation efficient in effective planting season.And the more important thing is that its well developed root system has directly improved drought resisting, the wind resistance of itself and fixed the sand ability.
3. the three-dimensional spin breeding that seeds such as mung bean, Chinese cabbage are carried out is handled, and has produced equal effect.
Other has experiment to show, the seed of same kind will show the notable difference on the statistical significance of having of physiological property to the notable difference of three-dimensional spin breeding action time.
