Key Points of Cabbage Planting Techniques and Detailed Field Management Methods

Cabbage is the collective term for vegetables in the genus Brassica of the cruciferous family. Common types include head cabbage, red cabbage, kale, Brussels sprouts and kohlrabi. It prefers a cool climate, has strong adaptability, and stores and transports well, making it one of the major vegetables widely cultivated across northern and southern China.

Cabbage is generally grown by raising seedlings first and then transplanting them. The seedling bed should be a loose, fertile plot; water it thoroughly before sowing, and after emergence pay attention to ventilation and temperature control to prevent the seedlings from growing leggy. Once the seedlings are growing vigorously and have a suitable number of leaves, they can be planted out. The planting field should have convenient drainage and irrigation, and as far as possible avoid plots whose previous crop was a cruciferous crop of the same kind, so as to reduce continuous-cropping obstacles.

In terms of field management, cabbage has relatively large fertilizer and water needs. During the rosette stage, nitrogen fertilizer should be the main type to promote full growth of the outer leaves; after entering the head-forming stage, more phosphorus and potassium fertilizer should be applied, which helps the head form tightly. Watering should be balanced and steady; during the head-forming stage keep the soil moist but avoid flood irrigation, and appropriately reduce watering before harvest, which can noticeably reduce head splitting.

Common diseases of cabbage include downy mildew, soft rot and black rot, while pests are mainly cabbage caterpillars, aphids and diamondback moths. In production, comprehensive control should combine measures such as crop rotation, cleaning the field, and reasonable close planting, and any signs of disease should be dealt with promptly. Once the heads are full and firm, they can be harvested in batches; harvesting too late makes them prone to splitting, affecting commercial quality and storage results.
