1、 Curing method

1. Temperature: it can also be seen from its main distribution area that it likes higher temperature, and it is more suitable at 20 to 30 degrees. It is not very cold resistant, so it is not planted much in the north. If you want to breed as an ornamental plant, you need to pay attention to cold protection

2. Light: it likes light very much. If it is kept in a dark environment for a long time, its growth will be very slow, and it is also prone to some diseases. Therefore, whether it is growing up or overwintering, we should try our best to provide sufficient light

3. Watering: it is a wet variety. Especially when it's flowering. Its flowering period is generally about 30 days. At this stage, watering must be timely. In the pod stage, it needs to be irrigated once or twice

4. Fertilization: the main method is topdressing outside the root. First, it's at flowering. At regular intervals, it is necessary to spray some fertilizer and water containing trace elements. In addition, the leaf surface also needs calcium superphosphate

2、 Breeding skills

1. Reproduction: sowing is often used. Because its seeds are relatively small and not easy to germinate, it is necessary to select high-quality substrates and pay special attention to the regulation of the surrounding environment after sowing, so that they can germinate more easily. The row spacing can be controlled at 20 cm. After sowing, the thickness of the covered soil can be about one centimeter. Then, it's better to control the temperature at 18 to 20 degrees

2. Changing pots: rape flowers can also be placed at home as potted plants, so you need to pay attention to changing pots at ordinary times. When selecting soil, we should pay special attention to two factors: one is the degree of fertility, that is, whether there is much nutrition, and whether it is loose

3、 Problem diagnosis and treatment

1. Disease: there may be "Sclerotinia Disease", which mostly occurs in flowering and fruiting period, and can be controlled by carbendazim. There may also be "viral disease", which can be prevented and treated with dimethoate emulsion

2. Pests: the main type of pests is "aphids". They can not only cause harm themselves, but also spread diseases. Omethoate can be used to deal with them

4、 Other issues

1. Toxicity: rape flower is not poisonous and will not cause harm to people

2. Whether it can be raised at home: Yes. It is not only a kind of cash crop, but also ornamental and can be made into potted plants
