1. Root: the rhizome is relatively thick and fat, and there are ventilation channels inside, which are buried in the underwater sludge, and white after cleaning. Edible, also known as lotus root.
2. Leaves: the leaves are round and shield shaped, with a diameter of 1 meter. The color is dark green, the surface has wax white powder, the edge is wavy.
3. Flowers: usually bloom from June to September. Flowers solitary at the top of the pedicel, raised above the water. There are many kinds of petals, such as single petal, double petal and double petal, most of which are white, pink, lavender and so on.
4. Fruit: the fruit is inverted cone-shaped, with hard peel and seeds. Seeds white, oval or ovate, edible and medicinal value.
1. Water quality: as an aquatic plant, lotus has strict requirements on water quality. It's better to take river water for aquaculture. Tap water needs to be dried for two days. In addition, the high temperature in summer leads to the rapid evaporation of water, to regularly add water to the basin.
2. Fertilization: most of the lotus fertilization is phosphorus and potassium, and the nitrogen fertilizer is a little less. If the soil at the bottom is more fertile, there is no need to apply fertilizer. If the leaves are yellow and thin, you can use urea and mud to rub them into small balls and put them in the basin for one week to recover.
3. Overwintering: the upper part of the plant withers in winter, but the rhizome is still alive and needs to be buried in the frozen soil. It can be watered properly to keep moisture. If the temperature is low, it needs to be covered with plastic wrap.
