A Detailed Guide to the Latest Field Management Key Points for Baby Napa Cabbage
Baby napa cabbage is very popular in our daily lives, and this vegetable has extremely rich nutritional value. However, many people think that baby napa cabbage is just napa cabbage, which is actually wrong. Baby napa cabbage has a crisper and smoother texture compared to napa cabbage. And its shape is also a bit different. The leaves of baby napa cabbage are yellow, and it is cooked after just a brief blanching. Nowadays, more and more people are growing baby napa cabbage, so how should it be managed during cultivation? Let's take a look below!
1. Intertillage and Weeding
About 10 days after baby napa cabbage emerges, one round of intertillage and weeding is needed. When intertilling, it is different from other vegetables. Because baby napa cabbage has relatively shallow roots, going too deep can easily damage the roots, so you only need to gently loosen the soil surface, which can effectively promote the development of baby napa cabbage roots. Also because of the shallow roots, we should carry out intertillage together with weeding to prevent weeds from competing for baby napa cabbage nutrients and affecting its growth. Regularly observe the growth of weeds in the field, and when there are too many weeds, carry out weeding separately.
2. Temperature Control
From after sowing until emergence, appropriately raise the temperature around baby napa cabbage to promote seed germination and emergence. However, after emergence, pay attention to ventilation and cooling. The daytime temperature must not exceed 25 degrees, and the nighttime temperature should be kept at around 11 degrees. Also, the amount of ventilation should gradually increase as the temperature rises. When the lowest daily temperature is 15 degrees, the greenhouse film can be removed directly. After removal, intertill and weed to raise the surface soil temperature and promote baby napa cabbage root growth. Also, carry out thinning according to the growth of the seedlings to increase baby napa cabbage yield.
3. Water and Fertilizer Management
Baby napa cabbage has moderate water and fertilizer requirements, with different levels of demand at each growth stage. For example, during the rosette stage, water and fertilizer application should be appropriately controlled. Do not use large amounts of water and fertilizer, as this is not conducive to rosette formation. During the heading stage, the demand for water is high, but when watering, small amounts and frequent watering should be the main approach to prevent excessive water from causing leggy growth in baby napa cabbage. After leggy growth, the density increases, raising the relative humidity in the air and triggering pests and diseases. Throughout the entire growth period of baby napa cabbage, there must be no fewer than two topdressings. The first is during the rosette stage, and then another topdressing during the heading stage.
4. Pest and Disease Control
Actually, the disease incidence rate of baby napa cabbage is relatively low, because baby napa cabbage has a short growth period and itself has strong disease resistance. However, we still must not let our guard down, because baby napa cabbage is still threatened by some insect pests. For example, diamondback moth and others. The incidence rate of diamondback moth is highest after sowing in early spring, so at this stage we must pay attention to pesticide control, and abamectin emulsifiable concentrate and similar products can be used. If other pests and diseases are found, you can refer to the control methods for napa cabbage, as their diseases are quite similar.
The above is the editor's brief introduction to the key management points for baby napa cabbage. Growing baby napa cabbage is actually very simple, but everyone still needs to manage it carefully. Only then can the quality and yield of baby napa cabbage be ensured and your own economic benefits from cultivation be further improved. That is all for today's introduction.
