How to Increase the Yield of Baby Napa Cabbage? Latest Planting Tips Shared
Baby napa cabbage is a vegetable that people love, and it can be eaten in every season. For growers, only through the yield of baby napa cabbage can they obtain higher returns. So how can the yield of baby napa cabbage be increased? Let's take a look at the detailed introduction.
1. Suitable varieties
Although baby napa cabbage can be planted in every season, its varieties differ, and different varieties adapt to different seasons. For example, if planting in spring, although the temperature is rising at this time, the average temperature is still relatively low, so cold-tolerant varieties should be chosen; if planting in summer, when the temperature is high, then heat-tolerant varieties must certainly be chosen; while the autumn climate is mild, so the requirements for varieties are not high. In addition, when planting, no matter what variety, priority should be given to the local market preference, and at the same time the growth characteristics of the variety should also be considered to see whether it is suitable for local planting.
2. Suitable temperature
When planting baby napa cabbage, temperature is extremely important. The temperature cannot be too low. If the temperature is below 5 degrees, it cannot germinate normally. And each growth stage has slightly different temperature requirements. During germination, the suitable temperature is 25 degrees, while during leaf growth the suitable temperature is 15-20 degrees. If the temperature is between 10-15 degrees, its growth will be extremely slow. If it is below 5 degrees, the plant may die from freezing, but if it exceeds 25 degrees, it is very easy to breed pests and diseases. Therefore, when planting, the suitable temperature is 5-25 degrees. At low temperatures, good insulation measures should be taken, and at high temperatures, cooling and pest and disease control measures should be taken.
3. Land preparation and fertilization
Before planting baby napa cabbage, first choose a suitable plot for planting. First, understand the suitable soil quality for baby napa cabbage. The best is sandy soil, and clay loam can also be used for planting. No matter what kind of soil, it must be ensured that it is loose, fertile and well-drained. After choosing the plot, first carry out deep plowing, then apply base fertilizer. Generally, 15 kg of compound fertilizer is applied per mu. If the soil is alkaline, an additional 20 kg of superphosphate should be applied to improve the soil and allow it to grow better.
4. Sufficient irrigation
Throughout the entire growth period of baby napa cabbage, in addition to fertilizing to provide nutrients for the whole process, there must also be sufficient irrigation. During the seedling stage, if the soil is dry, the seedlings will grow slowly or stop growing, but watering should not be done too much at one time; it is better to water a small amount frequently. The rosette stage is when water is most needed. At this time as well, it is not suitable to water too much at one time; it is better to water a small amount frequently. At the same time, avoid excessive humidity, which can lead to disease occurrence. Generally, watering should be stopped one week before harvest.
