Early maturing autumn cabbage has a short growth period, early time to market, and high planting efficiency. The following describes the high-yield cultivation techniques of early-maturing autumn cabbage.
1. Choose the best species. Early-ripening autumn cabbage should choose varieties with good early maturity, heat resistance, strong disease resistance and high yield.
2. Sowing at the right time. The growth period of early-ripening autumn cabbage is generally 50-60 days, and it is necessary to catch up with the mid-late ripe autumn cabbage in the large-scale planting area. Premature sowing is easy to induce pests and diseases, and the sowing date is too late, which will delay the listing period and lose the meaning of early maturing cultivation. The suitable sowing date is generally 7 days before the beginning of the autumn, and the listing period must be before the National Day.
3. Balance fertilization. This Chinese cabbage has a large demand for fertilizer, and it is combined with 5,000 kg of high-quality farmyard manure and 40 kg of ternary compound fertilizer. It is best to use a plot of cruciferous vegetables that has not been planted. For example, if the plot is planted for many years, it is necessary to apply 2 to 3 kg of biological fertilizer per acre to improve soil conditions and enhance the ability of cabbage to resist pests and diseases.
4. Field management. High ridge cultivation can be used in production to ensure that the dry water can be protected and the water can be drained. It is advisable to use on-demand, and put 3 to 4 seeds per hole, and the seedlings are twice. After the seedlings are strictly controlled, the seedlings will be controlled for about 10 days. After entering the rosette period, the key fertilizer and water management will be strengthened. In the initial stage of the rosette, 20 kg of urea or nitrogen and potassium fertilizer will be applied in combination with watering, and 20 kg of urea will be applied during the peak period. During the ball-forming period, the soil is dry and wet, ensuring sufficient water supply and increasing production.
