1. When planting lotus roots, it is necessary to build a pool with concrete in a sunny and open environment, and then lay a layer of oxygen-proof and impermeable film on the pool. After film mulching, a layer of red clay or black clay can be spread on the bottom of potted plants, and the covering thickness should be kept at 15 ~ 18 cm.

2. When planting lotus root, it is necessary to add base fertilizer in the pond to improve the fertilizer content of the soil. First, the decomposed farmyard manure is mixed into the clay, and then 30 kilograms of cake fertilizer or 50 kilograms of compound fertilizer is applied. After adding the base fertilizer, the soil and fertilizer should be fully mixed with a wooden stick.

3. After fertilization, lotus seeds can be planted in the soil, and April is the best time to plant lotus seeds every year. Before planting, lotus seeds should be directly buried in the soil, with the tip of lotus root facing down and not exposed outside the soil. In the process of planting, the spacing should be controlled at least one to five meters, and the row spacing should be controlled at least two meters.
