1. Planting time: Cabbage is also known as cabbage and cabbage. It is named after its leaves that are tightly wrapped together. It has strong disease resistance and high processing ability. It is one of the main vegetables in my country. There are extremely high planting prices. Cabbage is extremely adaptable and resistant to both heat and cold, so it can be grown in the open field in spring, summer and autumn across the country. In cold northern areas, seedlings are sown in spring, planted in summer and harvested in autumn. In the warmer areas of the south, planting can be mainly done in spring and autumn, or multiple crops can be planted.

2. Seed treatment: In order to ensure the germination rate, the seeds are usually exposed to the sun for about 3 days before planting. After exposure, the seeds are soaked in diluted potassium permanganate solution for 4-5 hours. , which can kill the germs carried by the seeds. After soaking, remove the seeds and wash them, wrap them in a wet towel, put them in a container for germination, keep the temperature between 20-25 degrees, wash them with warm water once a day, and the seeds will germinate successfully in about three days.

3. Sowing and raising seedlings: Sow the germinated seeds on the seedbed. Sow 5-6 grams per seedbed. Water the seedbed once before sowing. After the water has completely penetrated, cover it. A shallow layer of soil. Then you can sow. The seeds should be sown evenly so that they will be dense and uniform after they emerge. After sowing, cover them with a shallow layer of soil of about 0.5cm. After the seeds emerge, they will grow two or three true leaves and have a core. Can be planted.

4. Planting management: The temperature for planting should be warm and cool. The best distance between planting rows and plants is 40×36cm. Water once after planting to promote root growth. Cabbage has a relatively high demand for fertilizer and water. During the period from planting to cabbage core, it needs to be watered frequently, but it should not be too much each time, which is beneficial to stabilizing the seedlings. When the heart leaves begin to grow, watering can be combined with cultivating. The amount of watering should be greater than the water used to stabilize the seedlings in the early stage. This is used to slow down the seedlings. When the leaf ball has grown, the third watering should be greater than the water used to slow down the seedlings. In addition, when it enters the menstrual bulb stage, it is necessary to fertilize in time to supplement nutrients and promote growth.
