Background technique
Their Seed Germinating Period is the important stage of Ontogeny of plant, and good degree directly affects the late growth hair of plant
It educates and yield composition.Water is the necessary condition that seed is sprouted, and seed water suction is sprouted, and sufficient oxygen contact is to guarantee that seed can
Aerobic respiration is gone on smoothly, the premise of energy needed for sprouting is generated.It is generally believed that water oxygen level improve, be avoided that seed because
Anoxic anaerobic respiration and generate the phenomenon that harmful intermediate material leads to " rotten kind, rotten bud ".
The purpose of seed soaking is to absorb enough moisture before broadcasting for seed, makes enzyme activation in seed, is able to decompose endosperm
Interior nutrition, and then be transported to embryo portion enables radicle and plumule to sprout growth.Seed needs to suction itself during seed soaking
25% moisture is weighed, embryo can just sprout.The absorption speed of seed is decided by temperature, i.e. water temperature is high, and water suction is fast；Water temperature is low, inhales
Water is slow.
For traditional mode because of the environmental factor during being difficult to control seed presoaking and germinating, general seed rice suctions itself weight
25% moisture needs 100 DEG C~110 DEG C of accumulated temperature.Vernalization controls process of the seed in germination under the conditions of 28 DEG C~32 DEG C of temperature
In oneself generate a large amount of carbon dioxide, increase temperature naturally, slightly will appear burning bud situation without paying attention to.Seed usually occurs
Germination slowly, emergence rate it is relatively low and phenomena such as burn bud, occur the reason of these problems have alcoholism phenomenon, " burn bud " phenomenon,
The tacky phenomenon of seed-grain.It is ruptured when operation causes kind of skin, increases susceptible gene, reduces output ratio；Technique process of soaking seed is complicated, grasps
Make rigorous, large labor intensity, the quality for quality of soaking seed directly affects yield and quality.
Utility model content
The purpose of this utility model be for " burning bud " phenomenon, seed-grain existing for existing seed soaking technique it is tacky, malicious hurt embryo,

Under preferable case, it is provided with drying fan in room of soaking seed, for drying up the moisture of soaked the surface of the seed.
The micro-nano air-bubble seed soaking equipment of the utility model and common seed soaking equipment have unique difference, mainly by six
Aspect composition:
(1) charging property of micro-nano bubble and air bearing effect remove chlorine residue in raw water body, remove removing heavy metals and chemicals
Deng can purify water.
(2) micro-bubble explosion.Bubble explosion sterilization process can be divided into attraction and kill two processes.With adding for bubble
Compress it is small damage rupture by pressure, can inspire a large amount of free radical around bubble, rupture caused by superhigh-temperature and-pressure, can be suction
Attached bacterium kills.This process is a complete physical killing process, there is the area of essence with conventional disinfection and sterilization method
Not.It is recycled by the microbubble water of 10min, the bacterium and microorganism of 80% or more removal, bactericidal effect is significant, and pure physics kills
Bacterium, safety are without side-effects.
(3) oxygenation nanobubble water has certain facilitation to promotion seed germination effects.Micro-nano air-bubble by
In with very high permeability, it is thus possible to penetrate covering of a seed, accelerate seed germination；Seed is avoided to lead because of anoxic simultaneously
" the rotten kind, rotten bud " phenomenon caused improves percentage of seedgermination, shortens the germination period.It can accelerate the rate of seed growth, peroxide
It is higher to change adnosine deaminase activity, shows that its physiological activity is more preferable.
(4) micro-nano aeration process is used, makes oxygen/ozone high-efficiency dissolution in water, generates the oxygen/ozone of high concentration
Micro-nano air-bubble, at the same generate micro-nano bubble have slow release effect, can extend oxygen/ozone in water when retaining
