1、 Breeding environment

1. Light: Wanlian likes sunshine. It needs more than 7 hours of light every day. Sufficient sunshine is very beneficial to its growth. If it is cultured indoors, it should be moved to a place exposed to the sun, otherwise it will affect its growth

2. Water: different growth stages need different water. In the early stage of growth, too much water should be added, otherwise rotten roots will appear. With the continuous growth of other plants, appropriately increase the amount of watering, and pay attention to the cleanness of water quality, otherwise it is easy to cause infection and affect their growth

3. Fertilization: during cultivation, rotten soybean cake can be added as base fertilizer, and potassium fertilizer can be added when standing leaves to promote the formation of flower buds. The amount of fertilization should not be too large

4. Temperature: the temperature should be kept at 20 ℃ in order to grow and bloom normally. If it is lower than 15 ℃, it will be difficult to bloom

2、 Breeding method

Open the round end of the lotus seed with a tool so that water can seep into the seed. The seeds with broken shells are soaked in warm water for 2-7 days. After germination, they are hydroponically cultured. After a period of time, the second leaf can be planted after the root system grows

3、 Common diseases and insect pests

1. Aphids: they usually appear in the seedling stage. They can be caught manually in the early stage and sprayed with chemicals when they are serious

2. Diseases: common diseases include spot blight and corruption. After discovery, the diseased leaves shall be removed in time to reduce the source of infection, and then the leaves shall be sprayed with carbendazim. At ordinary times, they shall be ventilated frequently to ensure air quality
