What vegetables are suitable for planting in February? You need to master these planting precautions
Every February is a good season for farmers to begin full-scale spring plowing, as spring warms and flowers bloom and all things revive. So what vegetables are suitable for planting in February? What precautions need to be mastered? Let's take a look together!
What vegetables are suitable for planting in February?
1. Cucumber
Cucumber likes warmth and cannot tolerate cold. Its suitable growing temperature is 10-32°C. Generally, it grows best at 25-32°C during the day and 15-18°C at night; the most suitable soil temperature is 20-25°C, with a minimum of around 15°C. The most suitable day-night temperature difference is 10-15°C. At a high temperature of 35°C, cucumber photosynthesis is poor; at 45°C, high-temperature damage occurs; at a low temperature of -2-0°C, it freezes to death; if hardened at low temperature, it can withstand a low temperature of 3°C.
2. Spinach
Spinach can be eaten all year round, and it is relatively easy to grow. Just apply enough base fertilizer before sowing, then thin the spinach seedlings after true leaves grow out, and at the same time combine this with weeding. When 3-4 true leaves have grown, water once with diluted human urine and manure as a top dressing.
3. Carrot
Carrots are not limited to spring cultivation; autumn is also possible. Carrots are suitable for growing in soil with relatively high terrain and good drainage, and are even more suitable in soil rich in humus. Before planting, thoroughly plow the soil, and at the same time apply 3000 kg of decomposed farmyard manure plus 14 kg of potassium sulfate fertilizer per mu mixed together. Generally, for large-scale planting, they are grown on ridges in beds.
4. Chinese Cabbage
Chinese cabbage is relatively cold-tolerant and prefers a cool climate, so it is suitable for growing in cool seasons. If cultivated in high-temperature seasons, it is prone to pests and diseases, or poor quality and low yield, so it is not suitable for summer cultivation.
Precautions for vegetable planting in February
1. Keep vegetable plots warm and prevent freezing
Too low a temperature in vegetable plots not only affects the normal growth of vegetables, but continuous freezing damage may also cause the roots, stems and leaves of vegetables to rot.
2. Ventilation and light transmission
After the temperature rises, the humidity inside the shed will increase significantly, which is not conducive to warming the shed, affects the growth and development of solanaceous fruits and melon vegetables, and significantly increases the occurrence of diseases. At this time, great attention should be paid to ventilation and light transmission in the shed to reduce humidity inside the shed, and at the same time harmful gases such as ammonia and sulfur dioxide can be discharged in time.
Because growing vegetables is not very difficult, many friends already have their own set of experience. Everyone can make arrangements according to the specific conditions of the local weather environment, and remember to mainly follow temperature changes.
