Peanuts should be selected from the same year. When shelling, the diseased, shriveled and broken seeds should be removed, leaving seeds with large, full, bright color, smooth skin and consistent shape.

(2) seed soaking

Peanut seeds can germinate only when they absorb more than 40% of their own weight. The soaking time should not be too long. Soak the seeds in warm water at 20℃ 12 ~ 20 hours. After the seeds are soaked, rinse 1 ~ 2 times with clear water.

(3) accelerating germination

Peanut kernel can't germinate at 10℃, the optimum germination temperature is 25 ~ 30℃, and the germination rate can reach 95% after 3 ~ 4 days. When accelerating germination, use a flat plastic net container or a plastic seedling tray. The thickness of seeds should not exceed 4cm, and water should be sprayed 2 ~ 3 times a day, and it should be drenched every time to avoid overheating and rot of seeds.

(4) secondary germination

2 ~ 3 days after the first germination, select the germinated seeds once, remove the non-germinated seeds, and germinate the germinated seeds for the second time. The suitable temperature is 20 ~ 25℃. When the temperature is too high, the buds grow fast, but they are thin and easy to age. The temperature is too low, the growth is slow, the buds rot or the cotyledons open away from the petals for a long time, and the quality is poor.

(5) Harvest

During germination, the radicle first elongates and breaks through the seed coat, and the hypocotyl also elongates and thickens upward. Edible standard: root length 0. 1 ~ 1.5 cm, milky white, rootless. Hypocotyl is milky white, about 1.5 cm long and 0.4 ~ 0.5 cm thick. The seed coat did not fall off. When the seed coat was peeled off, the hypertrophy cotyledons were milky white with light brown flower stripes. Under normal circumstances, 3 kg of fruit buds can be produced per 1 kg of seeds.

The benefits of peanut bud:

The content of resveratrol in peanut bud is five times higher than that in peanuts, which is equivalent to that in wine. Resveratrol has the effects of inhibiting cancer cells, reducing blood lipid, preventing and treating cardiovascular diseases, and delaying aging. And has high health care value.

Peanut bud can also hydrolyze the protein in peanuts into amino acids, which are easily absorbed by the human body; Oil is converted into heat, and the fat content is greatly reduced. People who are afraid of obesity suggest taking it for a long time and improving the utilization rate of various trace elements necessary for the human body.
