Description
Technical field
The invention belongs to Rice Cropping field, is the seed ventilation seed-soaking method in accelerating germination of rice seed.
Background technology
Rice paddy seed will be soaked seed and vernalization prior to seeding.The main purpose of seed soaking makes seed suction moisture, accelerates seed germination, promotes seed germination uniformity.In rice paddy seed seed soaking process, add medicament kill the germ that seed rice carries.Conventional seed-soaking method is placed in fluid-tight container by seed, adds water seed to be immersed in water not soak 2 ~ 8 days not etc.In seed-soaking process, need duty to change water, stir more, increase oxygen content in water; Under temperature higher strip part, change water not in time, easily cause seed microbial growth, cause seed smelly, percentage of seedgermination declines.Presprouting of seeds needs suitable water, gas, heat condition, and in presprouting of seeds process, moisture is too many, causes seed anoxic to cause seed alcoholism, loses germination rate.China's hybrid rice accounts for 60% of Monitoring of Paddy Rice Plant Area, and hybrid rice seed price is high, and its germination rate not high needs increases seed consumption, increases the seed costs of unit are.
The shortcoming of traditional seed-soaking method is that when changing water, seed soaking agent is also outwelled, the DeGrain of seed soaking agent, and seed soaking amount is little.Seed soaking amount in current big farming household and farm is larger, and adopt conventional seed-soaking method then because grain weight causes greatly workload large, need often to change water, if change water will cause anoxic in water not in time, harmful microorganism grows, and soaks seed unsuccessfully.And because oxygen supply is not enough in the pregermination procedure of a large amount of seed, easily cause heating, rotten kind, burn seedling, the problems such as bud ratio is low, irregular.So, be badly in need of a kind of new presoaking and germinating method.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition is the problem of anoxic in water when overcoming vernalization in rice paddy seed seed soaking and water, realize the object of rice paddy seed presoaking and germinating in the water environment of temperature control air feed, solve that the rotten kind, the germination rate that run in conventional rice presoaking and germinating process are low, the problem such as irregular of germinateing.
For achieving the above object, the technical solution used in the present invention is: a kind of rice paddy seed ventilation presoaking and germinating method, rice paddy seed ventilation presoaking and germinating method, rice paddy seed is dipped in seed soaking solution, then within 5-10 minute, ventilate by every ventilation in 10 minutes in immersion seed rice, presoaking and germinating is crossed a Cheng Qian 24-72 hour temperature and is controlled 25 DEG C, soaks seed under within 24-48 hour subsequently, temperature is adjusted to the condition of 32 DEG C of constant temperature, show money or valuables one carries unintentionally until seed breaks chest, within 24 hours subsequently, temperature is adjusted to 26 DEG C of vernalization; Described ventilation utilizes aeration equipment to paddy rice seed rice bottom ventilation.
Further: described aeration equipment is air pump.
Further: described seed soaking solution is the aqueous solution containing killing seed rice germ.
Advantageous Effects of the present invention is:
(1) the inventive method is in seed soaking process, air is passed into bottom seed soaking solution, ensure that the oxygen content of air in soaking solution, solve the problem of anoxic in water in seed soaking process, decrease the trouble of artificial changing water, the effect of killing pathogenic bacteria medicament in seed soaking solution can be ensured simultaneously, avoid harmful microorganism to grow, ensure the standardization of presoaking and germinating process, the regularity improving effect of soaking seed and bud ratio and sprout, can reduce and change waterside number, be easy to extensive unified operation.
(2) by the inventive method, Germination Percentage of Rice is 83.4%, improves 27%, significantly improve the germination rate of seed than stuffiness presoaking and germinating germination rate 65.7%; Percentage of seedgermination improves can save seed costs, particularly saves hybrid rice seed cost, and meanwhile, stabilization of rice is produced.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the ventilation effect of soaking seed figure of the embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1
First after basking seeds, selection by winnowing full seed.Then with reference to accompanying drawing 1, air feed equipment is installed, Bubbled stone 3 is put into seed soaking basin bottom part through stratum reticulare 2, connects air pump 5 by sebific duct 4, then seed is laid on seed soaking basin division board, in seed soaking basin, add clear water (adding the agent of seed soaking liquid in clear water), make it cover seed 5cm.
