1、 Curing method

1. Temperature: it requires high temperature during the growth period. It can grow only when it is above 20 degrees. However, the temperature required for seed germination is relatively low. Generally, it can be sown when the temperature reaches above zero eight degrees Celsius

2. Watering: it is necessary to control the water before seedling emergence in order to promote the growth of root strips. When flowering, it is necessary to appropriately increase the watering and pricking water, because this time is its growth period, and the demand for water is relatively large. After the seeds are harvested, there is no need to water

3. Fertilization: when laying the base fertilizer, human and animal manure can be used. In addition, according to its growth, it also needs topdressing. The first time is in May, human and animal manure can still be used. The second time is when the seedlings grow to 30 cm, urea topdressing is needed; The third topdressing is in late July. At this time, its plant height should be about 60cm. The fertilizer should use fertilizer cake and potassium superphosphate

4. Light: because it is a plant with long sunshine, the light must be sufficient, and the light time every day cannot be less than eight hours

2、 Breeding skills

1. Propagation: it can propagate by sowing. First, it needs to select seeds and remove the shriveled and moldy seeds, so as to reduce diseases. Then, put the seeds into warm water for three hours, cover them with cloth for twelve hours, and finally sprinkle the seeds into the prepared cultivation base. When the seeds grow three real leaves, they can be transplanted and planted

2. Pruning: under normal circumstances, it does not need pruning. It only needs to dispose of the dry and rotten branches and leaves at ordinary times

3、 Problem diagnosis

1. Powdery mildew: if there are white powdery spots on both sides of the plant through the leaves, it indicates that the plant is infected with powdery mildew and needs to be sprayed with 25% Triadimefon solution for treatment

2. Disease: the yellowing of branches and leaves of plants is mostly caused by improper watering. Watering needs to be properly controlled to ensure the frequency of two to three times a week

4、 Other issues

1. Edible: it cannot be eaten directly, but its whole plant can be used as medicine

2. Toxicity: when taking medicine, it needs to be appropriate. If the dosage is too much, it will lead to the increase of blood pressure, especially for people with a history of hypertension
