1、 Curing method

1. Temperature: it is heat-resistant but not cold resistant, so it is not suitable for planting in the north. Most of its distribution is in the southwest. If the maintenance temperature is above 20 degrees, it can grow normally

2. Watering: it likes humidity, especially during the development period. It needs a lot of water. When the temperature is relatively high, it needs to be watered once every two days, and when the temperature is relatively low, it needs to be watered twice or three times a week. As a result, watering should be controlled in the future in order to promote the growth of fruits and pods

3. Fertilization: it consumes nutrients quickly, especially in the growth period. In addition to the base fertilizer used in the soil before planting, it also needs to be fertilized three to four times in the whole growth period. Fertilizer seeds should use fertilizer seeds with comprehensive fertilizer efficiency, and human and animal manure can also be used. When fertilizing, it should be noted that the fertilizer cannot directly contact the plant, otherwise the plant will be burned

4. Light: it is a plant with long sunshine. It has a great demand for light and can accept all day sunshine. If it is a potted plant, it is best to put it in a sunny place for maintenance, and the lighting time every day is guaranteed to be more than six hours

2、 Breeding skills

1. Propagation: rape can be propagated by sowing. Because the germination rate is relatively low due to the comparison of seeds, it is necessary to select a high-quality culture medium and adjust the maintenance environment, so as to improve the germination rate. If sowing in the open field, the row spacing should be controlled at about 20 cm. After sowing, it is necessary to cover it with a cm thick fine soil and water it once, so that it can germinate in about a week

2. Change basin: if the family is maintaining, the basin needs to be changed every year. When changing the basin, the rotten and dry root strips should be trimmed off, and the soil should use soil with good drainage and sufficient nutrients

3、 Problem diagnosis

1. Insect pests: rape is easy to be infected with aphids. Aphids will attach to the top of each branch and eat the young leaves of the plant, which will affect the health of the plant. At this time, Omethoate needs to be sprayed on it

2. Disease: rape is easy to be infected with sclerotinia disease in flowering and fruit stage. After infection, the leaves of the plant will turn yellow, which will directly affect the yield. During normal maintenance, prevention and control should be done well, and dimethoate emulsion can be used to soak and spray for prevention

4、 Other issues

1. Edible: it is edible and rapeseed can be pressed for oil

2. Toxicity: non toxic
