Description

Corn seed obtaining method

Technical Field

The invention relates to the technical field of corn planting, in particular to a method for obtaining corn seeds.

Background

The corn can be made into corn porridge and can also be eaten as fruits, vegetables or coarse food grains, and the like, and is generally popular among people due to high nutritive value and various eating methods.

The traditional corn planting mode is that seeds are directly scattered in soil, and the corn naturally grows through operations of fertilization, irrigation, pesticide spraying and the like. The seeds selected by the corns are usually directly purchased, and the directly purchased corn seeds are dry seeds, so that the method is mainly suitable for directly scattering the seeds in the soil for planting. Although the seeds purchased are soaked for indoor cultivation and germination, the seeds have uneven quality and are soaked for a long time, usually 1 to 2 hours, so that the efficiency is greatly reduced, and the seeds are usually directly dried in the air after being soaked and then cultivated indoors, so that the seeds cannot be kept continuously imbibed and swell, and the germination rate is influenced.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide the method for obtaining the corn seeds, which has short seed soaking time, high germination rate and high germination speed.

The technical scheme of the invention is as follows: a method for obtaining corn seeds comprises the following steps:

s1: seed selection: selecting the section with the most plump corn as a seed;

s2: and (3) storage: applying an insect-proof drug to the seeds, then airing, storing and sealing;

s3: seed soaking: and after the seedling raising time comes, soaking the seeds in water for 25-40 min, taking out, wrapping the seeds with bags, and naturally airing the seeds while keeping the seeds to have certain moisture.

Further, in S1, the section with the fullest middle part of the corn was selected as the corn seed.

Further, in S1, the selected corn is old corn.

Further, in S2, the moisture content of the air-dried seeds is less than 3%.

Further, in S2, the moisture content of the seeds after air drying is zero.

Further, in S3, the seeds are soaked in water for 2-3 months in the next year.

Further, in S3, in late 2 months of the next year, the seeds are soaked in water.

Further, in S3, the soaked seeds are wrapped in a wet bag.

Further, in S3, the water content of the naturally dried seeds is 3% -20%.

Further, in S3, the water content of the naturally dried seeds is 5% -10%.

The invention has the beneficial effects that: the plump section of the corn is selected as the seed, so that the best germination rate can be ensured, the sent seedling is the strongest, and the seed soaking time is short due to high quality; by applying the insect-proof medicine to the seeds before storage, the seeds can be protected from being gnawed by moths; by airing the seeds, on one hand, the seeds can be promoted to mature, the temperature of the seeds can be increased, and the activity of enzyme can be enhanced, and on the other hand, the seeds can be prevented from mildewing during storage; by soaking the seeds for 25-40 min, the seeds can be guaranteed to be imbibed and germinated, and the germination rate of the seeds is improved; through natural airing after seed soaking and keeping certain moisture, the seeds can be always kept in an imbibition state, so that the seeds can sprout quickly, and the germination speed is improved.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

A method for obtaining corn seeds comprises the following steps:

s101: seed selection: the fullest section of corn was selected as the seed.

Specifically, seeds from old corn were selected because old corn was more plump and gave stronger seedlings than young corn. The section with the fullest middle part of the corn is selected as the corn seed, because the section is full, the germination rate is the best, the seedling is stronger, and the corn grain is large and much; and the seed soaking time is short due to high quality.

S102: and (3) storage: the seeds are applied with an insect repellent and then dried to air for storage and sealing.

Specifically, the seeds are coated or sprayed with insect-proof medicines to prevent the seeds from being bitten by insects during storage, thereby affecting the germination rate. The seeds contain less than 3% moisture after air drying, and more preferably the seeds do not contain any moisture after air drying. In the embodiment, the seeds are required to be dried in the sun without moisture, so that the seeds are not easy to be wet and further do not go moldy in the storage process; and by sunning, the seed maturity can be promoted, the seed temperature can be increased, the activity of enzyme can be enhanced, and the life vitality and the germination rate of the seeds can be enhanced.

S103: seed soaking: and after the seedling raising time comes, soaking the seeds in water for 25-40 min, taking out, wrapping the seeds with bags, and naturally airing the seeds while keeping the seeds to have certain moisture.

Specifically, the optimum time for seed seedling culture is 2-3 months in the second year. Soaking the seeds in water for 30 min. If the soaking time is too short, the seeds are not easy to absorb water and swell, and the germination is too slow and even can not be germinated; if the soaking time is too long, it is meaningless and the seeds are easily soaked soft. The soaked seeds are preferably wrapped in wet bags to ensure that the seeds contain a certain amount of moisture and cannot be dried too much, and the moisture content of the aired seeds is preferably 3-20%, and more preferably 5-10%. If the seeds are too dry, the imbibition of the seeds is influenced, the germination is slow, and the germination rate is low; if the moisture content is too high, the temperature at germination is affected, and the germination rate is low.

The following is a preferred embodiment of the present invention:

s1: seed selection: selecting the plump section of old corn as seed;

s2: and (3) storage: smearing the insect-proof medicine on the seeds, then airing, and storing and sealing after moisture is avoided;

s3: seed soaking: and (3) soaking the seeds in water for 30min in the middle ten days of 2 months in the next year, taking out, wrapping the seeds with wet bags, naturally airing the seeds, and carrying out heat preservation seedling culture after the seeds are ensured to contain 5% of water.

In conclusion, the plump section of the corn is selected as the seed, so that the best germination rate can be ensured, the emitted seedling is the strongest, and the seed soaking time is short due to high quality; by applying the insect-proof medicine to the seeds before storage, the seeds can be protected from being gnawed by moths; by airing the seeds, on one hand, the seeds can be promoted to mature, the temperature of the seeds can be increased, and the activity of enzyme can be enhanced, and on the other hand, the seeds can be prevented from mildewing during storage; by soaking the seeds for 25-40 min, the seeds can be guaranteed to be imbibed and germinated, and the germination rate of the seeds is improved; through natural airing after seed soaking and keeping certain moisture, the seeds can be always kept in an imbibition state, so that the seeds can sprout quickly, and the germination speed is improved.
