Planting of peanut seedlings

Peanut seedlings we can usually see in large vegetable markets or supermarkets, belonging to relatively fresh and high nutritional value of food. So is the planting of peanut seedlings clear to everyone? Let's have a look today.

I. planting of peanut seedlings

Peanut seedlings should be planted in the same year, and diseased grains, shrunken grains and broken grains should be removed when the seeds are shelled. Soak the seeds in 20 ℃ warm water for 12 to 20 hours. Then in the appropriate temperature for two germination work, seedling plates stacked, each 5 plates for a pile; put an empty plate at the top, the empty plate covered with wet sacks or black film moisturizing, usually pay attention to shading.

2. Budding management of peanut seedlings

1. Peanut kernels could not germinate at 10 ℃, the optimum germination temperature was 25: 30 ℃, and the germination rate reached 95% after 3-4 days. Use flat-bottomed shallow plastic mesh containers or plastic seedling trays when sprouting. The thickness of the seeds does not exceed 4cm. Water should be drenched 2 or 3 times a day, each time to avoid overheating and rotten seeds.

2. After the first germination for 2-3 days, the germinated seeds were selected once, the ungerminated seeds were removed, and the germinated seeds were germinated for the second time, and the suitable temperature was 20-25 ℃. The temperature is too high, although the growth is fast, but the bud is thin and weak, easy to aging; if the temperature is too low, the growth is slow, the time is long, the bud or cotyledon opens and leaves, and the quality is poor.

3. Seedling plates are stacked, every 5 plates is a pile, with an empty plate on top, covered with wet sacks or black film to moisturize. Pour water 3 or 4 times a day, make sure that the seeds in the seedling plate are watered thoroughly, in order to take away the breathing heat, ensure the water and oxygen needed for peanut germination, and pour the plate at the same time. Do not accumulate water in the plate to avoid rotten seeds. It can be harvested in 7 days.

Peanut buds always keep dark during growth, fold the seedling plates after sowing, cover them with black film to block the light, and press a layer of wood on the buds to give some pressure to the buds, which can make the buds grow fat.
