Cabbage, also known as rapeseed or non-heading cabbage, is a fast-growing vegetable that can quickly boost the supply of fresh produce in the market. It's a popular choice for farmers due to its resilience and high yield potential. To ensure a successful harvest, proper cultivation techniques are essential.
First, it's important to select the right variety based on local climate and soil conditions. Different varieties may thrive under different environments, so choosing the appropriate one is key to maximizing growth and quality.
There are two main sowing methods: direct seeding and transplanting. For direct sowing, apply 4-5 tons of well-decomposed organic fertilizer before planting. Level the field, drill the seeds, and maintain a spacing of 20 cm between rows. After the seedlings emerge, thin them out when they have 4-5 leaves, adjusting the spacing to 15-20 cm. The seed rate should be around 0.5-0.8 kg per mu.
For transplanting, prepare a seedbed with loose, nutrient-rich soil. Apply 1.5-2.0 tons of organic fertilizer per acre as base fertilizer, and use 1.5-2.0 kg of seeds per mu. You can transplant seedlings from 5-8 acres. After sowing, water the area or press the soil with your feet to ensure good contact. Thin the seedlings 2-3 times after they emerge, keeping a distance of about 4 cm between them. Once the seedlings have 5-6 true leaves, they are ready to be transplanted. Before transplanting, follow similar fertilization and spacing guidelines as with direct sowing.
Proper fertilizer and water management is crucial for healthy growth. Apply urea as a top dressing once or twice before harvest, at a rate of 5-10 kg per acre. Stop applying any additional fertilizer 10 days before harvesting. Watering should be done in conjunction with fertilization. Water immediately after planting to help the roots establish.
Pest control is another important aspect of cabbage farming. Aphids are one of the main pests to watch out for. You can spray the plants with 40% Dimethoate EC diluted to 1000-2000 times or use 5% malathion powder. If possible, use insect nets with a mesh size of 25 or larger for full coverage to prevent infestation.
Harvesting can be done at various stages depending on weather conditions and local consumption preferences. Cabbage can be harvested from the four- to five-leaf stage up to fully matured plants. Early harvesting ensures tender leaves, while later harvesting allows for larger, more robust heads.
By following these steps, farmers can effectively grow high-quality cabbage that meets market demands and ensures a profitable harvest. With careful planning and attention to detail, cabbage cultivation can be both efficient and rewarding.
