Cultivation Techniques of Lotus Root

1. Planting environment

Lotus root is a kind of aquatic plant, so we should first aim at paddy field, and there is no shortage of water in the whole planting cycle of lotus root. The lotus root likes temperature, and its temperature should be kept above 15 degrees. And the shade tolerance of lotus root is relatively poor, so it is necessary to ensure that the planting land has sufficient light. Its planting soil should have sufficient nutrition and rich humus, which can promote the growth of lotus root. Finally, there should be certain windbreak plants around the planting site to prevent excessive wind volume from breaking the stems and leaves of lotus root. According to the requirements of the planting environment of lotus root, select the planting soil and then prepare to plant.

2. Planting at the right time

The lotus root is divided into two varieties: shallow water and deep water, the shallow water variety is suitable to grow in the paddy field with a water level of 20 cm, and the mature time is earlier, on the contrary, the deep water quality is suitable to grow in the paddy field of about 1.5 meters, and the mature time is longer. Then the planting time is controlled according to the planting area, which is usually carried out around March in the south. To ensure the integrity of the lotus root, there is an obvious difference in size between the lotus root body and the lotus root node. After sowing, the water level in the paddy field should be kept at least 6 cm to promote the growth of lotus root. Then the water level gradually deepens with the passage of time.

3. Water and fertilizer management

Lotus root grows in water, so water is an essential substance for lotus root planting. We have to control the water level according to the weather changes of the season. In summer, when there is high temperature and drought, the water demand of lotus root will increase greatly. Therefore, the phenomenon of water shortage can not occur, especially in summer. The growth of lotus root has a great demand for nutrition, so we also need to do a good job of fertilization. However, we should pay attention to the dosage, do not apply too much fertilizer at one time, prevent excessive fertilizer from leading to root burning, and apply a small amount of fertilizer as the principle.

4. Pest control

Diseases and pests are the most important things to pay attention to when planting lotus root. Because the harm of diseases and insect pests to lotus root is mild, it will lead to a substantial reduction in production, and heavy will lead to no harvest. Therefore, when we plant, we must do a good job of prevention. Disinfect regularly, control the amount of water and fertilizer, and strengthen the prevention and control work. The common diseases and insect pests of lotus root are Fusarium wilt, virus disease, diamondback moth and so on. We should have some understanding of these common diseases and insect pests to facilitate the timely detection of the disease. After the onset of the disease, we must find out what the specific diseases and insect pests are in time, and then take corresponding measures.
