How to grow lotus root

Lotus lotus root is slightly sweet and crisp, it can be eaten raw or cooked, and its medicinal value is quite high. Its roots, leaves, flowers and fruits are all treasures and can be nourished and used as medicine. So, how to grow lotus root?

First, how to grow lotus root?

The lotus root field chooses slightly acidic clayey soil with deep soil and rich organic matter. The species of lotus root should choose the mother lotus root or fully mature mother lotus root with plump head, complete neck bud, enlarged lotus root, small lotus root node, fat and sturdy back and bright color. When sowing, do as you dig, choose and plant. Keep 5-6cm shallow water in the early stage, promote germination and leafing, water depth 15-16cm in the middle stage, and shallow water in the later stage to facilitate lotus root formation. The petiole should not be broken during harvest, so as not to cause plant rot caused by water.

Second, what do you need to pay attention to when planting lotus root?

1. Temperature

The lotus root likes warmth. The seeds of lotus root above 15 ℃ can germinate, and the peak growth period requires a temperature of 20-30 ℃ and a water temperature of 21-25 ℃. The initial stage of lotus root formation requires a higher temperature to facilitate the expansion of the lotus root, while in the later stage, it requires a large temperature difference between day and night, about 25 ℃ in the day and 15 ℃ at night, in order to facilitate the accumulation of nutrients and the enrichment of the lotus root. During the dormant period, it is required to keep more than 5 ℃ and less than 5 ℃, so the lotus root is easy to be frozen.

two。 Light

Lotus root is a light-loving plant, not shade-tolerant, sufficient light is required during the growth period, and the requirement of sunshine length is not strict. Sufficient light in the early stage is beneficial to the growth of stems and leaves. Sufficient light in the later stage is beneficial to flowering, fruiting and enriching the lotus root.

3. Moisture content

There is no shortage of water during the whole growth period of lotus root. The sprouting stage requires shallow water, and the water level is 5-10cm. As the plant enters the vigorous growth stage, the water level is required to gradually deepen to 30-50cm. Later, with the flowering, fruiting and lotus root, the water level should gradually fall shallow, until the lotus root dormancy overwintering, as long as the soil is fully moist or keep shallow water. If the water level is too deep, it is easy to cause lotus root delay and thin lotus root body. When the water level rises sharply and the lotus leaves are submerged for more than 1 day, it is easy to cause the death of the leaves.

4. Soil nutrition

Loam and clay loam, which are rich in organic matter, are the most suitable for lotus root growth. the content of soil organic matter should be at least 1.5%. The soil pH is between 5.67.5 and 6.5is the most suitable. Lotus root requires equal emphasis on nitrogen, phosphorus and potassium, and there are some differences among varieties. The variety of seed lotus type needs more nitrogen and phosphorus, while the lotus lotus type needs more nitrogen and potassium.

Lotus has high ornamental value and high consumption of lotus root, so it seems that every place of lotus root is a treasure, and planting can bring good economic benefits.
