1. Lotus has no strict requirements on soil quality and can grow in a wide range. It grows best in clay soils rich in organic matter, with deep soil layers and strong water storage capacity.

2. Lotus roots love light. During the growth period of lotus roots, sufficient light must be maintained to help the growth of lotus roots. Lack of light will cause lotus roots to grow slowly, have poor fruit quality, and lose commercial value.

3. Lotus roots mainly use organic fertilizer as the base fertilizer, and the fertilizer must be fully decomposed. Top dressing is required during the growth period, and attention should be paid to the combined application of nitrogen and phosphate fertilizers. Silicon fertilizers and boron fertilizers can also be added.

4. Lotus root is a temperature-loving plant. The initial temperature for lotus germination is around 15°C, and the optimal temperature for growth is 28-30°C. The large temperature difference between day and night is conducive to the expansion and formation of lotus roots.
