Alfalfa Preserving Corn Seedlings

In recent days, the Shanhe Sub-district Office held an on-site precipitating seed meeting in the Yangpeng Village Group 2. The meeting was attended by Li Jianhua, Secretary of the Subcommittee of the Sub-district Office, Baocun Office of the Sub-district Office, Head of the Agricultural Bureau, Secretary of the Village Branch, and Regional Agricultural Technology Promotion. Station technicians, etc. Secretary Li made an important speech. The speech pointed out that now the township and the plains of the whole town have been planted and the stubble land cannot be planted. Since the sowing date has been postponed and postponed, it is necessary to adopt this kind of technical measures to ensure the safe planting of corn. , security emerged, safe and mature. Farmers used old-fashioned artificial eye-catching devices (artificially feeding a single seed and plunging into a seed in the soil) to conduct a seeding demonstration of corn germination seeds, and achieved good results. Farmers have stated that it is still not possible to plough the land in order to settle the land. At the meeting, technicians distributed technical information on germination. And for everyone to explain the corn germination technology and precautions.

The specific technology is:

1, drying seeds: pre-emergence drying 1-2 days. Improve seed coat permeability, enhance water absorption capacity; stimulate seed vigor, increase seed germination potential and germination rate.

2, soaking: The seeds into the container of water, the water more than seeds 8-10 cm, soaking with cold water 8-10 hours, soaking in warm water for 5-6 hours, the seed soaking time should not be too long.

3. Pregermination: Spread a layer of plastic cloth on the fire or on the wooden board; lay a layer of straw about 10 cm thick on the plastic cloth; then spread the sack or waste cloth on the straw; then use the soaked seeds. 30 °C warm water to wash it again, the purpose is to raise the temperature of the seed, wash the temperature of the seed to control the water; on a laid sack or cloth, the seed thickness does not exceed 10 cm; finally covered with warm water on the seed top The sacks or cloths are used for heat preservation and germination. Put the thermometer in the germination seed, control the temperature between 30-32°C, check the temperature of the seed every 3-4 hours, turn it up and down once, prevent the temperature from burning too high, and wash with 30°C warm water for 10-12 hours. Continue to germinate, usually 36-48 hours can be budding. When the seeds have just spit, they are dried in the shade.

4, should pay attention to the problem of germination:

(1) Seeds coated with a seed coating agent should be washed with a seed coating agent before germination, so as not to affect the germination rate.

(2) For corn seeds that have been primed, tebuconazole (trimethoxazole), triadimefon, and thiram can be used as seed dressings to prevent and control corn head smut. It is not advisable to mix the seeds of buds with a seed coating agent containing triadimefon and dilute oxazole to prevent phytotoxicity. Do not arbitrarily increase the amount of medication to prevent phytotoxicity.

(3) Use phoxim or chlorpyrifos, carbofuran granules mixed in the bottom fertilizer or seed fertilizer to control underground pests.

5, sowing

(1) Take 2 mm with the buds of the plow belt or planed pods to air dry the seeds.

(2) Seed sowing and planting are used. Seed buds are given a little longer. Generally, the length of shoots is about 4 mm. The buds of seeds are chopped off and air-dried and then sown, so as not to affect the seed quality. The first thing that grows from corn seed germination is the root. Drying or cutting off will not affect the seed growth.
