2. How to plant lotus roots

1. Choose a suitable lotus root field

(1) Soil: choose acidic or soil Neutral soil should be rich in organic matter and clay, and alkaline soil should not be selected.

(2) Growth elements: Nitrogen, phosphorus, and potassium are necessary elements for the growth of lotus roots, and the contents of the three elements will change according to different varieties of lotus roots. For example, lotus roots of the seed lotus type need More nitrogen and phosphorus, while lotus root type requires more nitrogen and potassium.

(3) Soil cultivation: The soil cultivation in the lotus root field should be selected according to the variety of lotus roots.

(4) Soil preparation and fertilization: The soil should be plowed deeply and finely, and usually the depth of the plow layer should be more than 35cm.

2. Choose a suitable lotus root pond

Choose a lotus root pond with suitable size and depth. If the lotus root pond is too large, it will be inconvenient for planting, management and pest protection; If the lotus root is too small, the lotus root cannot be derived and grown; if the lotus root pond is too deep, it is not convenient to dig mature lotus roots; if the lotus root pond is too shallow, it is not conducive to water replenishment and heat preservation in winter.

3. Select lotus root seeds

(1) Choose pure lotus root seeds with obvious characteristics.

(2) When planting lotus root buds, choose varieties with new buds in the lotus holes in the lotus nodes. It would be better if the new buds already have roots. This type of lotus root has a higher survival rate.

4. Dig a pit to bury the buds

(1) Dig a pit in the lotus root field. The size and depth of the pit need to be determined according to the size of the selected lotus root species.

(2) When planting lotus root seeds, you first need to bury the lotus root seeds tilted downward to protect the lotus root buds, and then leave the tail of the lotus root outside the soil.

(3) The spacing between rows is generally 200-200cm, and there are 500-600 buds per acre.

5. Watering lotus root buds

(1) Do not water newly planted lotus root seeds. You need to wait until the muddy water is slightly dry before watering properly. Add a little water, and make sure there is leakage at both ends when adding water.

(2) When watering, the principles of shallow in the early stage, deep in the mid-term, and shallow in the late stage should be followed. Lotus root fields should not be dry in winter to prevent lotus roots from freezing.

(3) When the lotus root grows to a certain length, water can be added. The water surface should be higher than the mud surface, but the tail part of the lotus root should not be submerged, otherwise water will enter the lotus root body and cause rot.

6. Maintain light

(1) Lotus roots like warmth, so ensure sufficient temperature and light when planting.

(2) Generally, lotus roots are planted in the north in early May, while in areas south of the Yangtze River, because the temperature returns quickly, they can be planted in early March to April.

7. Reasonable fertilization

(1) Fertilization period

① The basic fertilizer is generally 3000kg of decomposed farmyard manure per mu.

②After the lotus seeds and silt grow together, add a small amount of chemical fertilizer or natural fertilizer.

③ During the growth period of lotus root, weeds should be removed and human urine fertilizer added 2-3 times.

④ When the lotus root leaves grow 5 leaves, apply about 1000kg of urine fertilizer per mu of lotus root field.

⑤ When the lotus roots no longer grow leaves and start to form lotus roots, add the third fertilizer. In addition to applying more human urine fertilizer, you should also add appropriate cake fertilizer.

(2) Fertilization techniques and time

① Apply fertilizer in the morning or evening on a sunny and windless day.

② Before fertilizing, the water in the lotus root field needs to be drained. After the fertilization is completed, water can be poured into the lotus root field to the original water level.

③ When topdressing deep-water lotus root ponds, liquid fertilizer cannot be used directly. Solid fertilizer needs to be used and buried in the soil.

④ Before applying fertilizer, mix the chemical fertilizer and river mud evenly and make a fertilizer mud ball before applying it to the lotus root pond. The effect will be better.

⑤ When fertilizing, be careful to avoid burning the lotus root leaves.

8. Precautions

(1) The lotus root head should be facing down when planting.

(2) Weeding work must be carried out before the closure.

(3) When planting lotus roots, turn the lotus root heads so that the lotus roots are evenly distributed.

(4) After the flowering period, the flowers should be folded and the lotus pods should be opened in time.

(5) Prevent and control rot diseases, aphids, Spodoptera litura and other pests and diseases.

(6) Green lotus roots can usually be harvested in late July, and dry lotus roots can be harvested in late August.
