Selection of lotus seeds: choose the mother lotus with full lotus head, large lotus canopy and complete neck buds or fully mature lotus seeds as lotus seeds.
Planting method: directly plant the prepared lotus seeds into the soil, add shallow water with a depth of 5-6 cm in the initial stage, increase the water amount in the middle stage of growth, and then put shallow water in the later stage.
Field management: rational topdressing and strengthening pest control.
First, deal with Liantian.
Lotus root is suitable for growing in hot and rainy season. If planted in the south, it is usually planted in March-April. If it is planted in the north, it will be planted in early May. Lotus root belongs to aquatic plants. Choose cohesive soil with deep soil layer, rich in organic matter, slightly acidic to neutral, and add 5-6 cm shallow water to the soil. Lotus root consumes a lot of nutrients in the growth period, so it is necessary to apply decomposed chicken and duck manure as base fertilizer in the soil to improve soil fertility and meet the nutrient requirements of lotus root.
Second, choose lotus seeds.
In the lotus root, we should choose the mother lotus root with full head, full body, complete neck buds, small lotus nodes and bright colors, or we can choose the fully mature son lotus root, so that the survival rate can be guaranteed after planting. It is best to dig, select and plant.
Third, the planting method
The method of planting lotus root is very simple, directly planting the prepared lotus root seeds into the soil and controlling the depth. Pay attention to water level management after planting. At first, just leave 5-6 cm shallow water to promote germination and leaf pumping. It is better to increase the amount of water in the middle stage of growth, control the water depth at 15- 16 cm, and put shallow water in the later stage to promote the formation of lotus roots.
Fourth, on-site management
Lotus root likes fertilizer very much, and the demand for fertilizer is relatively large during its growth. However, too much fertilizer is easy to burn seedlings, so it is necessary to apply thin fertilizer frequently and spray new high-fat film, which can greatly improve the utilization rate of effective components of nutrient fertilizer and is not afraid of sun exposure. The quality of lotus root is high, and it needs to be sprayed with Diguozhuangdiling to make the nutrient transportation pipeline of underground fruit thicker, make the lotus root fatter, the meat crisp and tender, and the quality and yield are high. In addition, we should also pay attention to the prevention and control of pests and diseases, and use drugs in time once found.
