How do you grow baby napa cabbage to increase yield?
Baby napa cabbage is a vegetable people love, available in every season, and for growers, only through the yield of baby napa cabbage can they earn higher returns. So how do you increase baby napa cabbage yield? Let's take a look at the detailed introduction below.
1. Suitable variety
Although baby napa cabbage can be grown in every season, its varieties differ, and different varieties suit different seasons. For example, if planting in spring, when temperatures are still rising but the average temperature is still fairly low, you should choose cold-tolerant varieties; if planting in summer, when temperatures are high, you will certainly need to choose heat-tolerant varieties; while autumn has a mild climate, so the variety requirements are not strict. In addition, when planting, no matter which variety, you should give priority to local market preferences, and also consider whether the variety's growth characteristics suit local growing conditions.
2. Suitable temperature
Temperature is extremely important when growing baby napa cabbage; it must not be too low, because if the temperature falls below 5°C, it cannot germinate normally. Each growth stage also has slightly different temperature requirements: at germination the suitable temperature is 25°C, while during leaf growth the suitable temperature is 15-20°C. If the temperature is between 10-15°C, its growth will be extremely slow; if it is below 5°C, the plants may die from freezing; but if it exceeds 25°C, pests and diseases are very likely to develop. So when growing, the suitable temperature is 5-25°C; at low temperatures take good insulation measures, and at high temperatures take good cooling and pest and disease control measures.
3. Land preparation and fertilisation
Before planting baby napa cabbage, you must first choose a suitable plot to plant in. First understand the soil type baby napa cabbage prefers: sandy soil is best, and clay loam can also be used, but no matter what soil, it must be loose, fertile and well drained. After choosing the plot, first deep plough it, then apply base fertiliser; generally apply 15 kg of compound fertiliser per mu, and if the soil is alkaline, add another 20 kg of superphosphate to improve the soil and help it grow better.
4. Sufficient watering
Throughout the entire growing period of baby napa cabbage, besides fertilising to provide nutrients, there must also be sufficient watering. At the seedling stage, if the soil is dry, the seedlings will grow slowly or stop growing, but you should not water too much at once; it is better to water a little frequently. The rosette stage is when water is most needed, and here too you should not water too much at once; it is better to water a little frequently. At the same time, avoid excessive humidity, which causes disease; generally, stop watering one week before harvest.
