Abstract

A rice seed germination method relates to the technical field of rice germination. The technical scheme of the method is as follows: placing a moderate amount of rice seeds in a container containing a 0.2% KCl and 150mg/L gibberellic acid (GA) treatment solution; immersing the rice seeds at 28 DEG C for 8 hours and then taking out the seeds; packaging the rice seeds with a wet towel or a piece of gauze and then placing the packaged rice seeds in a germination box at a temperature of 28 DEG C for 5-7 days. The rice seed germination method can achieve the remarkable improvement on the germination ratio, germination momentum and seedling freshness quality of the rice seeds.

Description

A kind of germination method of rice paddy seed

Technical field

The present invention relates to Seed Germination of Rice technical field, particularly relate to a kind of germination method of rice paddy seed.

Background technology

The research of the domestic Germination Technique for rice paddy seed is also relatively on the low side at present, general just adopt or the Stratification technique of rice paddy seed in the industry, Main is: at clean container, load 50 ~ 55 DEG C of warm water, the water yield is 5 times of seed volume, seed is immersed in warm water and also constantly stir, stop stirring when water temperature drop to 30 DEG C, soak 8 ~ 12 hours again, seed is made to suction moisture, then water outlet, drain away the water, bind up with gauze, outside wraps the piece of sack or towel that soak again, put in basin alms bowl and carry out vernalization, this method is called hots water treatment of seeds, this is germination accelerating method the most frequently used at present, this method is simple and convenient, but also there are problems: seed sprouting is slow, bud gesture is weak, emerge irregular, large seedling phenomenon is serious, as seed dormancy, speed of emergence is slower, and bud rate is low.Paddy rice is a kind of very popular crops, and production occupies critical role, but rice seed germination is slow and irregular, in storage process, easy naturally-aged causes vigor to reduce, and therefore how to accelerate seed germination and promotes that seed sprouting seems very important.

Summary of the invention

The object of this invention is to provide a kind of germination method of rice paddy seed, it can significantly improve the germination rate of rice paddy seed, germination vigor and the fresh and alive quality of bud seedling.

In order to solve problem existing in background technology, the present invention is by the following technical solutions:

First get in the container that suitable quantity of water rice is put in containing 0.2%KC1 and 150mg/L gibberellin (GA) treatment fluid;

Soak seed 8 hours under 28 degree celsius temperature, then seed is taken out;

With the seed germination box putting into 28 degrees Celsius after wet towel or gauze parcel, through 5-7 days.

Compared with the conventional method, the inventive method beneficial effect following points:

1, with batch rice paddy seed, by the seed of this method process, the bud rate of bud rate 5%-8% can be improved;

2, with batch rice paddy seed, by the seed of this method process, germination vigor can emerge 93% in 5 days, improves 4 percentage points;

3, with batch rice paddy seed, by the seed of this method process, bud seedling quality significantly improves, and fresh and alive strong shape is energetic;

4, with batch rice paddy seed, by the seed of this method process, Phase ofsprouting improves, and seedling size is even.

Embodiment

A germination method for rice paddy seed, its embodiment and principle as follows:

Understand the processing method of seed germination, first seed germination is understood: son is sprouted and referred to a series of orderly physiology course of seed from imbitition and morphogenetic process, the sprouting of seed needs suitable temperature, certain moisture, sufficient air, during seed germination, first be water suction, after seed immersion, seed coat expanded, soften, more oxygen visible through the seed coat can be made to enter Interior Seed, carbonic acid gas visible through the seed coat is discharged simultaneously, and the physical state of the inside changes; Next is air, and the vital movement of the series of complex that seed carries out in germination process, only has seed constantly to breathe, obtain energy, normally carrying out of guarantee vital movement; Be finally temperature, temperature is too low, and photosynthesis weakens greatly, and respiration is suppressed, and rate of photosynthesis yield reduces, the decomposition of Interior Seed nutriment and other a series of physiological activity, all needs to carry out at suitable temperature.

The principle that the present invention uses 0.2%KC1+150mg/L gibberellin (GA) to process: gibberellin (GA) is as a kind of plant modifying agent, seed dormancy can be broken, accelerate Starch Hydrolysis in endosperm, promote seed sprouting, potassium is the required monovalent cation of plant part, it is dissolved in water with ionic condition, its major function is relevant with plant metabolism, the present invention is in the impact of mda content in rice seed germination characteristic and bud seedling body, improve the sprouting condition of rice paddy seed, the germination rate of rice paddy seed can be improved fast and effectively, germination vigor, quality fresh and alive with bud seedling.

Concrete operation method: get in the container that suitable quantity of water rice is put in containing 0.2%KC1 and 150mg/L gibberellin (GA) treatment fluid, soak seed 8 hours under 28 degree celsius temperature, then seed is taken out, with the seed germination box putting into 28 degrees Celsius after wet towel or gauze parcel, through 5-7 days, seed will fully be sprouted.
