Method for grow cabbage:
1, seed selection. There are many varieties of cabbage, each of which adapts to different environments, so you can choose the most suitable variety according to your region. For example, Hunan province is more suitable for planting water spinach, and the Yangtze River basin is more suitable for planting Chinese cabbage. The specific seed selection needs to be selected according to the specific situation.
2. Soil preparation. Chinese cabbage has strong adaptability to the environment and does not need specific soil and soil quality. However, when choosing land, we should pay attention not to choose continuous cropping land, which is prone to plague. You need to clean up the debris in the ground, then dig deep and prepare for drainage in advance. Finally, an average of one thousand catties of farmyard manure and fifty catties of plant ash were sown on each mu, waiting for sowing.
3. sow. There are two ways to grow cabbage. Lazy planting is to sow seeds at a certain distance, and then cover the seeds until the seeds emerge. Another method is to raise seedlings on the seedbed first and then transplant them.
4. management. The first thing after transplanting is to water every three to five days. When the seedlings formally survive, they need to be fertilized for the first time, accompanied by intertillage weeding, and the average fertilization per mu needs urea 100 kg.
The second fertilization is when the cabbage leaves begin to roll up slowly. An average acre of land needs 1000 kg of farm manure, 50 kg of potash fertilizer, 50 kg of compound fertilizer, 30 kg of phosphate fertilizer, and at the same time, it needs to be watered enough. If there is a lot of rain in the season, you should go to the fields to dredge ditches and discharge excess water.
5. Disease prevention. The common diseases of Chinese cabbage are downy mildew and black root disease. The way to prevent downy mildew is to spray chlorothalonil once every five or six days, just two or three times. Black root disease mainly harms the roots and needs to be prevented in advance. When preparing soil, disinfect the land with quicklime or spray chlorothalonil before planting.
