In February and January, the climate is still relatively cold. Try to choose frost-resistant vegetables when planting, such as Chinese cabbage, spinach, green onions, leeks, carrots, green vegetables, cabbage, arrowheads, rape, tomatoes, peppers and so on. These vegetables are very common and have low requirements for the environment. The planting method is not only simple, but also easy to manage.
1, spinach
Spinach has a certain cold tolerance, which is suitable for planting in early spring and February, especially in the northern region. At this time, the temperature is still unstable, and spinach can withstand low temperature for a short time, so it can grow well at this time, generally maturing in 30-50 days after planting.
Step 2: carrots
Carrots can be planted in early spring or autumn. When planting, you should choose plots with high terrain, convenient drainage and deep soil layer, so as to germinate better in this soil environment. If you want it to grow more vigorously in the later stage, you should also apply foot fat before burying it.
3. Chinese cabbage
Early spring and February are also suitable for planting Chinese cabbage. Cabbage likes cold environment. If planted at high temperature, it is easy to be infected with pests and diseases. However, it is best not to grow cabbage in the south at this time. After sowing in early spring, cabbage will be harvested in summer.
4, green onions
It is also suitable for planting green onions around February, which has certain cold tolerance. When planting, choose a plot with deep soil layer and fertile soil. After planting, it is necessary to strengthen management, water in time, loosen the soil and do a good job of drainage in rainy season. The growth period of Welsh onion is 120- 150 days.
Key points of growing vegetables in January and February
1, heat preservation and cold protection: Vegetables planted in February and January are easily attacked by late spring cold, resulting in strong cooling and low cold resistance of plants, resulting in freezing injury and chilling injury of vegetables. It is necessary to strengthen the work of heat preservation and warming, and seal the greenhouse before the arrival of late spring cold.
2. Ventilation and light transmission: After the temperature rises, the humidity in the shed will increase obviously, which will affect the growth of vegetables and increase the occurrence of diseases. At this time, attention should be paid to ventilation and light transmission to reduce the humidity in the shed, and at the same time, harmful gases such as ammonia and sulfur dioxide can be discharged in time.
3. Disease control: The high humidity in vegetable shed is easy to cause gray mold. So pay attention to ventilation. After spring, it is necessary to prevent damping-off disease, damping-off, root rot, downy mildew, anthracnose, early blight, eggplant brown streak, Sclerotinia sclerotiorum, celery spot blight and so on. , but also prevent aphids.
