Abstract
The invention belongs to the field of rice cultivation and discloses a seed ventilated soaking method in rice seed accelerating germination. The method comprises the following steps: soaking rice seeds in a seed soaking solution, introducing gases into the soaked rice seeds every 10 minutes for 5-10 minutes for ventilating, controlling the temperature to be 25 DEG C within 24-72 hours before the seed soaking and accelerating germination process, regulating the temperature to be 32 DEG C within the subsequent 24-48 hours, soaking the seeds under the condition of constant temperature until the seeds are broken and exposed, regulating the temperature to be 26 DEG C within the subsequent 24 hours for accelerating germination. According to the method, air is introduced into the bottom of the seed soaking solution in the seed soaking process, the oxygen content in the air in the soaking solution is guaranteed, and the problem that the water lacks of oxygen in the seed soaking process is solved. According to the method, the germination rate of rice seeds is 83.4 percent and is improved by 27 percent compared with the ventilation-free seed-soaking accelerating germination rate of 65.7, and the germination rate of the seeds is obviously improved. Moreover, the germination rate of the seeds is improved, the cost of the seeds can be saved, particularly the cost of hybrid rice seeds is saved, and the rice production is stabilized.
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 to kill the germ that seed rice carries.Conventional seed-soaking method is that seed is placed in fluid-tight container, adds water seed is immersed in and in water, does not soak 2～6 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 that seed is 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 not high seed consumption and the seed costs of not only increasing of its germination rate also incured loss through delay and produced season.
The shortcoming of traditional seed-soaking method is that while changing water, seed soaking agent is also outwelled, the DeGrain of seed soaking agent, and seed soaking amount is little.Seed soaking amount in big farming household and farm is larger at present, adopt conventional seed-soaking method because grain weight causes greatly workload large, need to often change water, if change water, will cause anoxic in water not in time, and harmful microorganism grows, and soaks seed unsuccessfully.And in the vernalization process of a large amount of seeds, because oxygen supply is not enough, easily cause heating, the problem such as rotten kind, burns seedling, and 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 while 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 in conventional rice presoaking and germinating process, run into 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 to immersion seed rice in by every 10 minutes ventilation within 5-10 minute, ventilate, presoaking and germinating is crossed under 25 ℃ of conditions of temperature control in Cheng Qian 24-72 hour and is soaked seed, 24-48 hour subsequently temperature is adjusted to vernalization under the condition of 32 ℃ of constant temperature, until the broken chest of seed shows money or valuables one carries unintentionally, within 24 hours subsequently, temperature is adjusted to 26 ℃ of vernalization, until reach sowing requirement.
Further: described ventilation is to pass into from the bottom of seed rice.
Further: described ventilation is to utilize aeration equipment to paddy rice seed rice bottom ventilation.
Further: described aeration equipment is air pump.
Further: described seed soaking solution is to contain the aqueous solution of killing seed rice germ.
Useful technique effect of the present invention is:
(1) the inventive method is in seed soaking process, to seed soaking solution bottom, pass into air, guarantee the oxygen content of air in soaking solution, solved in seed soaking process the problem of anoxic in water, reduced the trouble of artificial changing water, can guarantee the effect of killing pathogenic bacteria medicament in seed soaking solution simultaneously, avoid harmful microorganism to grow, guarantee the standardization of presoaking and germinating process, the regularity that improves 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%, than stuffiness presoaking and germinating germination rate 65.7%, improves 27%, significantly improves the germination rate of seed; 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, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
