Latest Technical Methods and Tutorial for Field Management of Baby Cabbage
Baby cabbage has a relatively short growth cycle; it usually matures 45-55 days after planting, and since it can be planted all year round, it can be brought to market in large quantities within a very short time. So how should baby cabbage be managed after sowing? Let's take a look at the detailed introduction.
1. Temperature management
Generally, seedlings emerge 4-5 days after sowing. After emergence, mulch should be applied in time to ensure sufficient temperature for growth. If planting in a greenhouse, there is no need to apply mulch. However, pay attention to the day-night temperature difference, which should preferably not exceed 13 degrees. During the day, strengthen ventilation to lower the temperature inside the shed and reduce fertilization, thereby reducing the occurrence of diseases. When planting in a small arched shed, as the temperature rises, increase the ventilation openings. When the low temperature reaches the teens, the film can be removed, and combined with intertillage and weeding, this raises the soil temperature and promotes root growth.
2. Water management
Baby cabbage has an underdeveloped root system and a relatively small rhizome, so during planting the soil must be kept sufficiently moist to ensure normal growth and development. When baby cabbage enters the heading stage, this is the period of its greatest water demand, and it is also a period of excessively high temperatures; high temperature and high humidity can easily breed diseases. Therefore, when watering, control the amount well to avoid excessive humidity at the roots inducing rotten hearts. If it rains, drain water promptly to reduce humidity.
3. Fertilizer management
Because baby cabbage has a relatively short growth cycle, the soil must be ensured to have sufficient fertility to support its growth. During planting, apply base fertilizer in combination with land preparation, mainly organic fertilizer. In cases where the base fertilizer is insufficient, to avoid the plants stopping growth due to lack of fertilizer, a small amount of manure water fertilizer can be applied at this time. In addition, topdressing should be carried out during the three periods of baby cabbage: the rosette stage, the early heading stage, and the mid-heading stage, so as to ensure the normal growth of baby cabbage.
4. Intertillage and weeding
Weeding work is carried out during land preparation, but weeds cannot be completely eliminated. As baby cabbage grows, a large number of weeds will grow again in the field. These weeds compete with baby cabbage for water and fertilizer, and also provide a good habitat for pests and diseases, resulting in poor ventilation and air permeability in the field and making pest and disease damage more likely. Therefore, weed frequently. Manual pulling of weeds is recommended. If the planting area is too large, pay attention to the concentration and application method when using pesticides, so as to avoid phytotoxicity to baby cabbage.
