Vegetables in peanut bud are newly developed new pollution-free and high-grade sprouts. Peanut bud cuisine can be produced all year round by adopting the new method of soilless culture technology in foam box, and there is no need to apply chemical fertilizers and pesticides in the production process, so there is no pollution. The production process is introduced as follows: 1. Variety selection: select small peanut varieties, and select new varieties with full seeds, uniform size, no damage, strong germination potential and high germination rate. 2. Production site: The production in peanut bud needs strict temperature and humidity conditions, and generally does not need illumination, but the air is fresh and smooth, so you can use the idle living room or abandoned idle room. Winter cultivation should use places that can keep warm, such as greenhouses or plastic greenhouses. 3. Foam box specifications: all kinds of foam boxes can be used. 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 in warm water at 20℃ 12- 17 hours, and rinse with clean water 1 time. Spread a layer of newspaper on 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, which plays the role of heat preservation, moisture preservation and sun protection. 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 bud length is 1 cm, all the seeds that will not germinate will be removed. The suitable temperature for the growth of peanut bud is 18-25℃, and more water should be sprayed in summer to cool down, and heat preservation should be strengthened in winter. Sprinkle water 3-4 times a day during the growth period, preferably with clean well water, and the amount of water sprayed each time shall be subject to the fact that the seedlings are all wet and the substrate is soaked. During cultivation, the room should be kept dark and invisible, otherwise the peanut bud will turn green, which will affect the appearance and taste. 6. Harvest: Under normal cultivation environment, it takes 7-8 days in summer and autumn and 8- 10 days in winter and spring. When the new bud grows to 12- 15 cm, the top petal unfolds without cotyledons, rotten stems, peculiar smell and roots, and it can be harvested. First, the definition of sprouts: sprouts are dozens of edible varieties such as pine willow, sprouts chicory, buckwheat sprouts, alfalfa sprouts, pepper sprouts, black sprouts, peanut bud, silkworm sprouts and so on. Second, the significance of developing sprouts In recent years, Japan, the United States, the European Union, Singapore, Thailand, Southeast Asia and Hong Kong and Macao have conducted extensive research on the nutritional and medicinal value of sprouts. It is generally believed that sprouts have many functions such as anti-aging, anti-cancer, weight loss and beauty. It is better not to eat meat than to eat vegetables. With the improvement of people's living standards, people have to pay more attention to the appearance, quality and food safety of vegetables. As a kind of nutritious, high-quality and pollution-free green health food, sprouts are favored by consumers. Therefore, sprouts are a promising new vegetable industry.
