What are the planting methods of peanut buds?

Peanut seeds can be eaten as sprouts after germination, which is called peanut buds. After peanut germination, its protein has been decomposed into amino acids, the fat content is low, the vitamin content is increased in an all-round way, and various nutrients are more easily absorbed by the human body. So what are the planting methods of peanut buds?

1. Variety selection

There are many varieties of peanuts, and it is best to use small-grain varieties to produce sprouts. With seedling plate production, each plate with seeds (dry weight) about 500 grams, generally peanut bud length is 2 times the seed body length, each plate can produce 1.2 kg peanut buds.

The seeds are required to be full, uniform in size, intact and with a germination rate of more than 95%. Before production, peanut species are selected manually, broken grains and shrunken grains are removed, and those of similar size are selected together for separate production.

2. Seed soaking treatment

Then wash the selected seeds with clean water and soak for 10 hours for 12 hours to make the seeds fully absorb water and expand (the maximum water absorption of the seeds is required to reach 51%-55% of the seed weight). Finally, rinse the seeds with clean water for 2 or 3 times. Do not use iron utensils when soaking seeds.

3. Sowing and sprouting

Remove the seeds from the water, drain the surface water, and put them into a clean container free of oil, salt, acid and alkali to germinate. The bottom of the container should be well drained. More oxygen is needed in the process of peanut bud growth, and the thickness of seeds in the container should not exceed 4 cm. Before sprouting, cover with a thick towel, control the temperature between 23-26 ℃, and sprinkle water 2-3 times a day to avoid overheating the seeds. After sprouting, pick out the seeds that can not germinate and the residual seeds, and continue to sprout.

If you prefer long peanut buds, you can also spread a layer in a sterilized seedling plate (rinse with bleach or potassium permanganate solution and rinse with clean water), usually 500 grams per plate. Every 8-10 plates of a pile, the implementation of stacked plates to promote sprouting.

4. Daily temperature and humidity control

The lowest temperature for accelerating germination growth of peanut is 15 ℃, the optimum temperature is 20-25 ℃, and the highest temperature is 30 ℃. Humidity should be kept humid and cultured in shade in a well-ventilated environment. If the temperature is low in winter, it should be cultivated under the condition of heat preservation and shading in middle shed or greenhouse. Each production cycle is 8-10 days.

5. Timely harvest

When the peanut bud is 1-2 cm long, the seed coat is intact, and the cotyledons (peanut petals) are not unfolded, they should be harvested in time. If the cotyledon unfolds and the bud is exposed, it is easy to be afforested and the quality is reduced.

Note: peanut buds must not be visible in the process of cultivation, in order to prevent greening. Iron products are prohibited in the containers for the production of peanut buds, otherwise the seed coat is prone to rust color and affect the quality. The water used must be clean, sterile tap water or iron-free deep well water, and the water temperature must reach the greenhouse standard (above 20 ℃), otherwise it will affect the normal growth of peanut buds.
