My understanding of lotus root from an early age tells me that lotus root is very suitable for growing in mud. The thinner the mud and the darker the color, the more suitable it is for lotus root growth. The lotus root grown in this environment tastes good and is big, but the only drawback is that it is difficult to dig. However, a small number of fields in the sludge have become "sludge" due to domestic sewage and industrial wastewater, and the soil contains more iron, manganese, zinc and lead.
Many people in the landlord's hometown plant lotus roots in ponds or rivers. Lotus root plants are huge, extremely tolerant of fertilizer and like soft and fertile cohesive soil. Generally, these lotus roots are planted in fertile ponds with deep silt and convenient irrigation. Lotus root grows well in silt and can promote the growth of lotus root. It is not convenient to dig when it is cooked. You need to feel it with your feet or go deep into the mud in the water to take it out.
Deep-water lotus root: suitable water surface should be selected for planting, and shallow lakes and river bends should be selected for deep-water lotus root, with gentle water flow and stable fluctuation, and the thickness of underwater silt layer is above 20 cm. The highest water level in summer flood season shall not exceed 120cm. From the first vertical leaf to the bud. Generally, the middle and lower reaches of the Yangtze River begin to grow and enter the seedling stage in mid-May. The typical characteristics of this period are accelerated plant growth, increased number of leaves, increased total leaf area and enhanced photosynthetic efficiency.
