1、 Curing method

1. Substrate selection: sunflower doesn't have too many strict requirements for soil, so you don't have to pay too much attention to the selection of soil, but the best is the loam with good drainage and fertile soil

2. Light management: sunflower likes a warm environment and requires sufficient light. It likes the ventilated plot of Chaoyang, has strict requirements for light, and doesn't like the cool environment

3. Temperature management: it likes warmth and is afraid of cold. The most suitable temperature for sunflower is 25-30 ℃. The temperature below 15 ℃ will affect the flowering and fruiting. When the temperature is below 14 ℃, the growth will become very slow. Therefore, the breeding temperature must be controlled

4. Water management: it likes dry and humid environment, but it doesn't like waterlogging. Too dry will easily lead to weak plant growth, too wet will lead to bacterial wilt, so you should keep the soil moist

2、 Breeding skills

If the outdoor temperature is difficult to reach in winter, it should be transferred indoors. Do not water too much at this time, otherwise it is easy to form waterlogging, which is not conducive to its winter
