Key points of artificial cultivation technology
1? Selection of site, soil quality and water source: rural and urban vegetable gardens, fertile rice fields, shallow ponds and swamp mud can be cultivated. It needs to keep water all the year round, and the water depth is above 10 ~ 20 cm. Dry land saline-alkali land cannot be planted. Greenhouse planting can spray water in shallow water all year round.
2? Cultivation methods and planting season arrangement: ivory vegetables can be planted in a wide range, with the temperature above 5℃ and the optimum temperature of 25 ~ 28℃, and can be introduced and cultivated all year round. Before planting, the land should be leveled, soaked in water, and then fully raked once or twice to put enough base fertilizer. When planting, the roots of seedlings are inserted into the mud, with a depth of about 15cm, and the plant spacing requirements are: 1m× 1m, with 660 plants per mu. After planting once per mu, it can be harvested continuously for 5 ~ 6 years. If we expand the sale of seedlings, we can grow them at will, and then we can collect them in batches and transport them to various places for sale.
3? Fertilization: Ivory vegetable has strong fertilizer tolerance, and nitrogen, phosphorus and potassium fertilizer are generally suitable. However, in order to maintain its natural green quality, organic manure should be used mainly, and pig, cow, human and horse manure should be fully fermented before application, with a dosage of 2000 ~ 3000 kg per mu. Topdressing once every 10 ~ 15 days after harvesting to ensure its vigorous growth.
4? Harvesting and processing: under suitable temperature conditions, harvesting can be started about 15 ~ 20 days after planting, once every 5 ~ 10 days in spring and summer, and once every 15 ~ 20 days in winter. Ivory vegetables are harvested and eaten by the tuber of lotus root. They crisscross and grow in the mud. When harvesting, people should be very careful not to trample on rotten or broken buds. They should slowly grope for the harvest from the inside out and from top to bottom along the roots. The harvested ivory vegetables should be washed with water first, and then sold in different grades. If it can't be sold out on the same day, it can be packaged and delivered in fresh-keeping bags. Under the condition of 4 ~ 5℃, it will not deteriorate after storage for 5 ~ 10 days. If it can be packed in vacuum, its preservation period can reach 20 ~ 30 days. In addition, ivory vegetables can be further processed into high-grade canned food, sweet and sour preserved fruit and dried vegetables, which are sold at home and abroad to increase foreign exchange income.
