Peanut sprout vegetable is a new type of pollution-free high-grade sprout vegetable developed recently. Peanut sprout vegetable can be produced all the year round by adopting the new foam box soilless cultivation technology, without the use of chemical fertilizers and pesticides in the production process and without pollution. The production technology is now introduced as follows:

Cultivation of Peanut Sprout in foam Box

1. Variety selection.

When choosing small peanut varieties, it is necessary to use new varieties that are full, uniform in size, undamaged, have strong germination potential, and have a high germination rate.

2. Production site.

The production of peanut sprouts and vegetables has strict requirements for temperature and humidity conditions. Generally, light is not required, but fresh and smooth air is required. Idle living rooms or abandoned idle rooms can be used. Winter cultivation should be carried out in places such as greenhouses or plastic greenhouses that can be heated.

3. Specification of foam box.

All kinds of foam boxes can be used. Generally, 60 cm long, 40 cm wide and 25 cm high boxes are selected. The bottom of the box is required to be flat with drainage vents.

4. Sowing.

First, wash the seeds and remove any debris, seed coat, and impurities that float on the water surface. Then soak in warm water at 20 ℃ for 12-17 hours, and rinse with clean water once in the middle. Put a layer of newspaper at the bottom of the foam box, spread 2cm thick clean river sand, evenly sprinkle the soaked seeds on the sand surface of the box, and then cover a layer of black plastic film on the foam box to keep warm, moist and dark. It is advisable to maintain the temperature inside the box at 23-28 ℃ and spray water 2-3 times a day.

5. Cultivation management.

After 2-3 days of sowing, when the seed bud is 1 centimeter long, remove all the non sprouting kernels. The optimal temperature for the growth of peanut sprouts and vegetables is 18-25 ℃. In summer, more water should be sprayed to cool down, and in winter, insulation should be strengthened. During the growth period, water should be sprayed 3-4 times a day, preferably with clean well water. The amount of water sprayed each time should be sufficient to ensure that the sprouts are fully wetted and the substrate is moist. During the cultivation period, the indoor area should be kept dark and invisible to light, otherwise it will cause the peanut buds to turn green, affecting the appearance and taste.

6. Harvesting.

In a normal cultivation environment, from sowing to harvesting, it takes 7-8 days in summer and autumn, and 8-10 days in winter and spring. Harvesting can be carried out when the sprouts are 12-15 centimeters long, the top petals are unfolded without any exposed cotyledons, rotten stems, odors, or fibrous roots.
