How deep soil is needed for planting lotus roots, and what are the requirements for water quality?

1, soil depth: the thickness of the soil for planting lotus roots is generally about 35-50cm, which should not be too shallow, because the lotus roots need a thicker soil layer for fixation, expansion, random extension and absorption from the soil. 2. Other requirements: it should be planted in fertile clay loam with shelter from the wind and the sun, good water retention, deep soil layer, rich humus, ph value of 6-8.5 and organic matter content of 1.5% or more.

1. How deep soil does it take to grow lotus roots?

1, soil depth

Due to the fixation of lotus root stem, the expansion of lotus root, the random extension of lotus root whip and the nutrient absorption of lotus root, a thick soil layer is needed. If the soil layer is too shallow, it can't meet the normal growth of lotus root. Generally speaking, the thickness of soil is about 35-50 cm.

2. Other requirements

(1) In general, lotus roots should be planted on fertile clay loam with shelter from the wind and the sun, good water retention, deep soil layer, rich humus and organic matter content above 1.5%.

(2) The ph value of the soil planted with lotus root should be between 6 and 8.5. The soil acidity is too high, and the soil hardening is serious, which is not conducive to the growth of lotus root, while the soil is too loose, which will shorten the internodes of lotus root, make the pulp thick and hard, and have poor quality.

2. What are the water quality requirements for lotus root planting?

1, lotus root does not require high water quality, as long as it is not water containing too many acidic or alkaline substances, but it does require water level.

2. At the initial stage of planting, it is advisable to keep the water level in lotus field at about 3-5cm. When floating leaves appear, the water level deepens to about 6-7 cm. When 2-3 vertical leaves grow, the water level deepens to about 10cm. With the gradual increase of temperature and the continuous growth of lotus root, the water level will gradually deepen to about 15-20cm, and it can reach about 30cm when it is deep, but the highest water level should not exceed 50cm.

3. When the drooping leaves are full of lotus fields and leaves begin to appear, the water level should drop to about 10cm. If the original water level is deep, the water level can be reduced to about 15cm, but the highest water level shall not exceed 20cm.

4. Drainage during the day, and irrigation at night when the lotus root is knotted and swollen. The specific method is to lower the water level to about 3-5cm during the day and raise the water level to about 10- 15cm at night.
