Description
Technical field
The invention belongs to Rice Cropping seedling-raising technique fields, and in particular to a kind of processing side promoting rice seed germination
Method.
Background technology
In order to improve germination percentage and reduction seed incidence of insect disease after rice growing, have much to kind by research
The processing method of son, traditional processing method includes basking seeds, sterilizing the processes such as liquid disinfectant, seed soaking, vernalization, wherein that soaks seed is main
Purpose is that seed is made to suction moisture, accelerates seed and sprouts, promotes the consistency of rice seed germination, in rice paddy seed seed soaking process
The middle medicament that is added kills the germ carried in seed rice, and conventional seed-soaking method is to add water by the air-locked container in seed house
By 2-6 days submerged in water of seed, need during soaking it is diligent change water, stir more, increase oxygen content in water, it is higher in temperature
Under conditions of, it changes water not in time, be easy to cause seed microbial growth, cause seed smelly, percentage of seedgermination declines, and seed is urged
Bud needs 11 water, air and heat condition, and anoxic can cause seed alcoholism, germination percentage to reduce during presprouting of seeds, not only
Seed costs can be increased, can also be delayed production season, seed soaking agent will usually be outwelled in traditional seed-soaking method, if replaced too late
When will appear harmful microorganism grow, seed soaking failure the problems such as, therefore, it is necessary to a kind of processing methods of seed to solve above ask
Topic, and improve the germination percentage of seed and promote rice seed germination.
Invention content
The purpose of the present invention is for existing problem, provide a kind of processing method promoting rice seed germination.
The present invention is achieved by the following technical solutions：A kind of processing method promoting rice seed germination, including with
Lower content：

The seed soaking device includes inlet and liquid outlet, need the rice paddy seed of seed soaking by gauze bag sealed envelope after
It hangs in seed soaking device, the feed speed of the seed-soaking liquid is identical as liquid speed degree is gone out, and is 0.1-0.2m3/s；
The seed-soaking liquid equipped with rice paddy seed gauze bag can be flooded by being equipped in the seed soaking device, and the seed-soaking liquid is by following parts by weight
Raw material be made：26-30 parts of rice straw, 8-12 parts of Drilgrass, 1-2 parts of mandarin oil, 0.2-0.8 parts of salicylic acid；
（2）It is 18-22 DEG C, handled 3-5 hours under the dark condition equipped with circulated air in temperature after the completion of seed soaking, is put into after the completion
Vernalization in culture dish.
As further improvement of these options, the preparation method of the seed-soaking liquid is：By rice straw, Drilgrass with
Absolute ethyl alcohol mix, temperature be 135-145 DEG C, 1.2-1.4MPa under conditions of keep 20-40 minutes, filter and receive after the completion
Collect filtrate, product liquid is obtained by distilling, standing, the water dilution for being equivalent to 2-3 times of its weight is added, salicylic acid is then added
It stirs evenly, after being kept for 8-12 minutes, pH adjusting agent is added, adjusts pH value 6.8, mandarin oil is then added and stirs evenly to obtain the final product.
As further improvement of these options, the rice straw and Drilgrass are being 3- using preceding moisture content
5wt% is crushed to grain size before use and is not more than 2mm.
As further improvement of these options, the pH adjusting agent is the sodium hydroxide that mass concentration is 6-8%.
As further improvement of these options, the seed-soaking liquid derived from liquid outlet flows through filter device filtering
Afterwards, it is used for Rice Cropping.
As further improvement of these options, the seed-soaking liquid is added after base manure application, addition 60-
80kg/ mus.
The present invention has the following advantages compared with prior art：Seed soaking agent is added after base manure application in the present invention, Neng Gouti
The absorption of high plant pair base manure improves utilization rate of fertilizer, contributes to the potential quality for playing kind high yield, under identical breeding condition
3-7% can be increased production；The processing method of seed in the present invention can effectively prevent oxygen content in seed-soaking liquid relatively low, while also can be to making
Seed-soaking liquid after is effectively treated, and avoids the degradation of starch in seed, promotes the raising of seed starches enzymatic activity, coordinates dark item
It is handled under part, the protective enzyme activity in seed can be excited, the sprouting ability of seed is improved, improve seed germination rate, according to
After conventional method plantation, Rice Panicle shape is made to increase, well developed root system, yield effectively improves.
