1: Pot soil
The planting technology of lotus roots requires flexible control of the soil conditions. Lotus roots do not have high requirements for soil quality, but the pot soil generally needs to be added to 2/5 or 1/2 of the spray basin body. If the lotus roots are thick, you can add more pot soil, and vice versa. If the soil is soft and the density is small, you can add more pot soil. For some, after adding the pot soil, fill the pot with water and soak it for about a week. If the pot water is dark green and has a large number of yellow-green bubbles, it means the pot soil is too fertile. You can rinse it with clean water until the pot water is light green and clear. The bottom can be planted.
Two: Fertilization
Potted lotus roots are less resistant to fertilizer than edible lotus roots. The volume of the pot is limited, the lotus roots have small space to stretch underground, and the root system is dense, so potted lotus roots cannot be planted blindly. of excessive fertilization. The general fertilization principle is to fertilize less during the floating leaf stage, fertilize frequently during the standing leaf stage, but not too much, and fertilize more during the flowering and fruiting stage. When fertilizing, the fertilizer should not come into contact with the lotus leaves and should be placed directly in the center of the pot. in the water.
Three: Watering
Summer is its peak growth season. Do not add water during the dormant period in winter. Add water once a week when it is growing vigorously. There are no requirements for water quality and it is pollution-free. Just use lotus pond water.
Four: Insect Pests
As long as it is placed in a ventilated and sunny place, there is basically no disease. Only aphids may be infected in early spring. Dilute it with washing powder and water 600 times. Can be sprayed. Moss or duckweed may grow in the south, which can be fished out manually.
Five: Overwintering management
After frost, petioles, pedicels, and dead leaves should be cut off. Fill the pot with water, and adopt different methods according to different regions. South of the Yangtze River, you can overwinter directly in the open air. In the Huanghuai region, cover it with a double layer of film. In the northeast and northwest regions, cover the pot with a layer of plastic film and the film. Add some soil and then cover with film.
