1、 Breeding environment

1. Soil: water hyacinth has high requirements for soil. It is best to use soil with loose texture and good water absorption

2. Light: it cannot be exposed to too strong light. It is a plant with short sunshine. It is best to ensure sufficient light during its growth. It should be properly shaded in summer, or placed in a cool place with scattered light for maintenance

3. Temperature: the growth environment of water supply gourd should be 20-30 ℃. During germination, it is best to control the temperature at 30-35 ℃. The temperature should not be too high or too low. If the temperature is lower than 15 ℃, it will grow slowly, if it is lower than 10 ℃, it will stop growing, and if it is lower than 5 ℃, it will suffer from freezing injury

4. Watering: during the vigorous growth period, we should increase the amount of watering to ensure sufficient water, which is conducive to its growth. We should water less when flower bud differentiation

2、 Breeding method

Ramet propagation: generally, ramets are carried out in spring. The horizontal stolons are cut into several sections and then put into clean water. This method is very convenient to operate and has a high survival rate

3、 Common diseases and insect pests

Diseases are most likely to occur in high temperature and non ventilated environment. Green insect pests will appear in low temperature and non ventilated environment, which will devour the tender leaves of water hyacinth. A small amount of pests can be captured manually. If it is too serious, it can be sprayed with dimethoate emulsifier and ventilation can be strengthened
