Cultivation methods and precautions of water chestnut

1. Maintenance methods

1. Light management: During the maintenance process, the young water chestnut seedlings should be kept away from direct sunlight as much as possible. As it grows slowly, increase its light exposure time. An average of 4.5-5.5 hours of light per day is appropriate, which is beneficial to its growth.

2. Water quality selection: Water chestnut is a perennial submerged herb, so it usually appears in ponds, rice fields, ditches and rivers. Therefore, it requires a lot of nutrients from the bottom mud, and the pH of the water is generally slightly acidic to neutral, which is conducive to growth.

3. Nutrient management: In the process of cultivating water chestnuts, sufficient nutrients should be provided, and the bottom mud and water quality need to have sufficient nutrient salts.

4. Temperature management: The optimum growth temperature is around 15-20 degrees Celsius. If the temperature is suitable, it will bloom in April and May, and will wither and rot in June.

2. Breeding techniques

1. Cuttings: Plant cuttings in the bottom mud. The nutrient salts in the bottom mud and water should be sufficient. Increase the water level in time and pay attention to avoid strong sunlight exposure for the seedlings. Generally speaking, the time for cuttings can be in spring.

2. Sowing: Because it starts to bloom in April and May, the most suitable time for sowing is autumn. It starts to germinate in autumn, and winter and spring are its growing seasons.

3. Problem diagnosis and treatment

1. Yellowing leaves: If yellowing leaves occur, it is most likely due to an imbalance in the pH of the water. Excessive acidity, alkalinity, or excess nutrients in the water can easily cause the leaves to turn yellow. The pH value should be adjusted in time to maintain nutritional balance.

2. Root rot: If water chestnuts have root rot, it is most likely caused by insufficient oxygen in the water. Oxygen and light should be increased in time.

IV. Other issues

1. Is it toxic? Water chestnut is a perennial submerged herb. It is non-toxic and has sufficient nutrients. It is a good vitamin supplement.

2. Pruning and maintenance: As it is an aquatic plant, it reproduces very quickly and can spread throughout the entire lake in a short time under suitable conditions. Therefore, it needs to be pruned weekly to avoid excessive density.
