Cultivation methods and precautions of water shield

Cultivation methods and precautions of water shield

1. Maintenance methods

1. Fertilizer: If there is sufficient base fertilizer for growing water shield, there is generally no need to apply top dressing. If you find that the leaves of the plant are small or yellow, you need to apply appropriate topdressing. The second thing is to apply decomposed cake fertilizer before it sprouts in spring every year.

2. Temperature: The most suitable environmental temperature for its growth is between 20-30℃. If it exceeds 40℃ in summer, it will grow slowly. When the environmental temperature is below 15℃ in winter, it will stop growing.

3. Soil: Water shield generally grows in paddy fields, and the water depth of the paddy fields needs to be 20-60CM. The requirements for water quality are relatively high. It is best to breed it in a place with clean water and the soil should be rich in nutrients.

4. Light: When growing water shield, it is best to grow it in a location with better light. Its growth is highly dependent on light, and it needs sufficient sunlight to carry out photosynthesis so that it can grow better.

2. Breeding techniques

1. Reproduction: Water shield is generally propagated by cuttings, because its seeds are not easy to germinate, in order to have a better harvest. The most commonly used method is cuttings, which is best done in March or April in spring.

2. Transplantation: Water shield can be transplanted all year round, but the survival rate is higher in spring, and it is better from late March to mid-April.

3. Problem diagnosis and treatment

1. Pests: Because it is farmed in water, snails are its common natural enemies. They usually start in the water and feed on the stems and leaves of the plants. In the early stages of discovery, you need to spray them with 800 times diluted 90% crystalline dichlorvos.

2. Disease: The most common disease is leaf rot, which is quite harmful to water shield. This is usually caused by poor water quality or uncomposted organic fertilizer. Just clean or change the water in time.

IV. Other issues

1. Is it edible? Water shield can be eaten. It is widely planted in many areas of my country and can be commonly found.

2. Is it poisonous? Water shield is not toxic at all. Since it is edible and has certain economic value, it is widely cultivated.
