1、 Curing method

1. Temperature: the cold resistance of chaocai is better. As long as the temperature is above zero, it will grow. When the sowing temperature is about 10 degrees, the seedlings will grow. It is not resistant to high temperature. If the temperature exceeds 30 degrees, the plants will grow slowly

2. Watering: it likes a humid living environment and should keep the soil moist for a long time. The water consumption of branching stage and green pod stage is relatively large, so it needs to be supplemented with water. If the soil is kept dry for a long time, the plant will grow poorly. It needs to be watered every other week

3. Fertilization: in the growth process, it consumes phosphorus rapidly, so the plant is prone to more nitrogen and less phosphorus. In this period, it needs to use phosphorus fertilizer to ensure the balance of nitrogen and phosphorus and promote future yield. Fertilization frequency is once a month

4. Light: it cannot accept strong light irradiation, which will affect its growth. Therefore, astigmatism should be the main way of illumination, and the illumination time should be guaranteed to be four hours a day

2、 Breeding skills

1. Propagation: it can be propagated by sowing. First of all, we need to mix base fertilizer in the soil. Generally, 1500 kg of organic fertilizer is used per mu. The selected seeds are sown into the soil in the way of drill sowing, the row spacing is kept moist for 30 cm, the sowing cover is covered with soil, and it is watered with fecal water once. Generally, the seedlings can emerge in a week

2. Weeding: weeds often grow in the place where it is cultivated. In order to avoid weeds competing with plants for nutrition, weeding should be carried out regularly. When weeding, it should be noted that chemicals cannot be sprayed on the nest vegetables

3、 Problem diagnosis

1. Insect pests: plants are easy to be infected with insects such as caterpillars and bug bugs. If found, insecticides should be sprayed to eliminate insects

2. Disease: after the plant emerges, it should be often sprayed with carbendazim to enhance its disease resistance. It is easy to be infected with powdery mildew and leaf spot. If it is infected, the infected seedlings should be pulled out and destroyed as soon as possible to avoid further infection, and then the plants should be sprayed with chemicals for control

4、 Other issues

1. Edible: it can't be eaten, but it can be used as medicine

2. Toxicity: it is toxic during flowering, so avoid contact with its juice during maintenance. Wear gloves and masks during operation. If you accidentally contact the juice, you need to wash it with clean water and see a doctor as soon as possible
