Peanut sprout vegetable is a newly developed new type of pollution-free high-grade seedling vegetable. Peanut sprout vegetable can be produced all year round by adopting the new method of foam box soilless culture technology, and there is no need to apply chemical fertilizers and pesticides in the production process, which is pollution-free. Now its production technology is introduced as follows: 1, variety selection: select small peanut varieties, and use new varieties with full grains, uniform size, no damage, strong germination potential and high germination rate. 2. Production site: The production of peanut sprouts requires strict temperature and humidity conditions, and generally does not require light, but requires fresh and smooth air, and can use idle living rooms or waste and idle rooms. Winter cultivation should use places that can be heated, such as greenhouses or plastic greenhouses. 3. Specifications of foam boxes: foam boxes of various specifications are acceptable. Generally, boxes with a length of 60 cm, a width of 40 cm and a height of 25 cm are selected, and the bottom of the box is required to be flat, with drainage vents. 4. Sowing: First, wash the seeds and remove the seeds, seed coats and impurities floating on the water. Then soak it in warm water at 20℃ 12- 17 hours, and wash it with clean water 1 time. Put a layer of newspaper at the bottom of the foam box, spread clean river sand with a thickness of 2 cm, spread the soaked seeds evenly on the sand surface in the box, and then cover the foam box with a layer of black plastic film to keep warm, moisturize and shade. It is advisable to keep the temperature in the box at 23-28℃ and spray water 2-3 times a day. 5. Cultivation management: 2-3 days after sowing, when the seed bud length is 1 cm, all the seeds that will not sprout will be removed. The optimum temperature for the growth of peanut sprouts is 18-25℃, so it is necessary to spray more water to cool down in summer and strengthen heat preservation in winter. Sprinkle water 3-4 times a day during the growth period, preferably with clean well water, and the amount of water to be drenched each time is that the seedlings are all wet and the substrate is soaked. During the cultivation period, the room should be kept dark and invisible, otherwise the peanut bud will turn green, which will affect the appearance and taste.
