Detailed Explanation of Lotus Root Planting Techniques and Field Management Key Points
1. Planting Environment
Lotus root is an aquatic plant, so first of all, paddy fields should be the target, and water must not be lacking throughout the entire lotus root planting cycle. Lotus root prefers warmth, and the temperature should be maintained above 15 degrees. Moreover, lotus root has relatively poor shade tolerance, so it is also necessary to ensure that the planting site has sufficient sunlight. The planting soil should have sufficient nutrients and be rich in humus, which can promote the growth of lotus root. Finally, there should be certain windbreak plants around the planting site to prevent excessive wind from breaking the lotus root stems and leaves. After selecting the planting soil according to the requirements of lotus root for the planting environment, prepare for planting.
2. Timely Planting
Lotus root is divided into two varieties: shallow-water and deep-water. Shallow-water varieties are suitable for growing in paddy fields with a water level of 20 cm and mature earlier. Conversely, deep-water varieties are suitable for growing in paddy fields with a water level of about 1.5 m and take longer to mature. Then control the planting time according to the planting region. In the south, it is generally done around March. It is necessary to ensure that the seed lotus root is intact and that there is an obvious size difference between the lotus root body and the lotus root nodes. After sowing, the water level in the paddy field should be maintained at at least about 6 cm to promote the growth of the seed lotus root. Then, as the growth time progresses, gradually deepen the water level.
3. Water and Fertilizer Management
Lotus root grows in water, so water is an essential substance for lotus root cultivation. We should control the water level according to seasonal weather changes. In summer, with high temperatures and drought, the demand of lotus root for water will also increase greatly at this time. Therefore, especially in summer, water shortage must not occur. The growth of lotus root also has a relatively large demand for nutrients, so we should also do a good job in fertilization. However, pay attention to the amount. Do not apply too much fertilizer at one time to prevent excessive fertilizer from burning the roots. When fertilizing, follow the principle of applying more frequently but in small amounts.
4. Pest and Disease Control
Pests and diseases are what require the most attention when planting lotus root. This is because the harm caused by pests and diseases to lotus root can range from a large reduction in yield in mild cases to a total loss in severe cases. Therefore, when planting, we must do a good job in prevention. Disinfect regularly, control the amount of water and fertilizer, and strengthen prevention and control work. Common pests and diseases of lotus root include fusarium wilt, viral disease, and slug moths, etc. We should have some understanding of these common pests and diseases so that we can promptly detect outbreaks. After the disease occurs, it is necessary to promptly identify exactly what pest or disease it is, and then take corresponding measures.
