When is the best time to plant lotus root? High-yield lotus root cultivation techniques
Lotus root tastes crisp and sweet, and it is a vegetable loved by many people. It can not only be stir-fried, but also served cold or eaten raw. Many people are curious about its planting time and how to cultivate it to achieve high yields. Let's take a look together.
1. Planting time
Lotus root is generally planted in March to April, because its optimal growing temperature is between 20 and 30 degrees, so to plant lotus root, the lowest temperature must be at least 15 degrees, otherwise it is extremely difficult for it to survive. In addition, because the temperature difference between the north and the south is relatively large, in the south it is more suitable to plant in February to March, while in the north it is suitable to plant in April to May.
2. Seed selection
Seed selection for lotus root is also an extremely critical point. Be sure to carefully observe whether there are new tender buds emerging from the lower part of the lotus root, and then check whether there are also some rhizomes growing out again around it. If there are, such seedlings can be taken and planted directly. Second, when selecting seeds, choose lotus roots with a length and number of segments of at least three or more nodes and with no damage for planting. The most important thing is that they are free of viruses, so that the lotus roots grown will be larger and better.
3. Sowing
After selecting lotus root seeds, do not leave them for too long; plant them immediately. However, before planting, some treatment should be carried out on the lotus root seeds. After evenly mixing targeted medicines, take them for planting. Only in this way can the effects of pathogenic bacteria and viruses encountered by the lotus root seeds during the growing period be effectively reduced. When planting, plant deeply, so that the lotus root seeds can grow better. As for planting density, choose 30-50 cm per plant when planting.
4. Field management
One month after planting the lotus root seeds, lotus leaves and lotus flowers will grow out. At this time, we need to remove the flower buds and leaves to prevent them from affecting the growth of the lotus root. If they are not removed in time, they will continue to absorb nutrients, which will cause the lotus root to grow poorly. When the lotus leaves grow to 5-6 leaves, we need to topdress once, and when the pond is full of lotus leaves, fertilize once again. Because many tender lotus roots have begun to grow and need a large amount of nutrients, when the leaves no longer grow after the last fertilization, it means the lotus root has begun to grow, and at this time the nutrient demand is even greater. In addition, at this time the water level should be controlled at about 10-15 cm.
