1. Temperature: the cold resistance of chaocai is good, as long as the temperature is above zero, it will grow. Sowing temperature in about 10 degrees, seedlings will be unearthed growth, it is not high temperature, temperature more than 30 degrees, the plant will grow slowly.
2. Watering: it likes the humid living environment and needs to keep the soil moist for a long time. The water consumption in branching stage and podding 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 suffer from poor growth. Every other week, we need to water it.
3. Fertilization: in the growth process, it consumes phosphorus rapidly, so the plant is prone to the situation of more nitrogen and less phosphorus. In this period, it needs to use phosphorus fertilizer to ensure the balance of nitrogen and phosphorus, and also can promote the future yield. Fertilization frequency is once a month.
4. Light: it can't receive strong light, which will affect the growth, so the way of light should be mainly based on astigmatism, and the time of light should be four hours a day.
1. Reproduction: it can be propagated by sowing. First of all, we need to mix the base fertilizer in the soil. Generally, 1500 kg organic fertilizer is used per mu. The selected seeds will be sown into the soil in the way of strip sowing, with a row spacing of 30cm. After sowing, cover the soil with the back cover, and water it with fecal water once. Generally, the seedlings will emerge in a week.
2. Weeding: there are always weeds growing 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 the agent cannot be sprayed on the chaocai.
1. Insect damage: plants are easy to infect insects such as caterpillars and bug bugs. If found, insecticides should be used for spraying.
2. Disease: spray carbendazim regularly to the plant after emergence to enhance its disease resistance. It is easy to be infected with powdery mildew and leaf spot. If it is infected, it is necessary to pull out and destroy the infected seedlings as soon as possible to avoid further infection, and then spray the plants with chemicals for prevention and control.
1. Edible: it can not be eaten, but 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 the juice is accidentally touched, clean it with water, and then see a doctor as soon as possible.
