What vegetables can I grow in January and February?
1.Open field vegetables
The main varieties of open-field vegetables that can be planted in February are greens, cabbages, broccoli, bowl beans, etc. The main tasks are fertilization, drainage after rain, and bowl beans racking. Cabbage, late spring lettuce, and spring cauliflower can be successively planted and covered with plastic mulching; spring radish is sown in the middle and late of this month, and varieties that have short growth periods, strong cold resistance, and are not easy to hollow are cultivated, such as white jade spring radish and spring white 2 .
Greenhouse vegetables
The most cultivated varieties of melon and vegetables in plastic greenhouses are silty pumpkins, cucumbers, and loofahs. The sowing period of dwarf lettuce beans in greenhouse cultivation is generally from mid to late February. Early spring leafy vegetables such as spinach, amaranth, artemisia annua, coriander, celery, etc. can generally be sown in the latter half of the year. Others such as spring Chinese cabbage, spring cabbage, spring radish, etc. can be planted in greenhouses and small arches.
Notes on Vegetable Planting in February
1. Insulation and cold protection
February is susceptible to the coming cold spring, which causes strong cooling. In addition, after the spring is warm, the greenhouse eggplant, fruit, melons and vegetables grow vigorously, and the plant's cold resistance ability is significantly reduced, which can easily cause crop freezing damage and cold damage. It is necessary to strengthen the greenhouse thermal insulation work to reverse the cold spring. Fasten the greenhouse film to seal the greenhouse before coming.
2.Ventilation and light transmission
After the temperature rises, the humidity in the shed will increase significantly, which is not conducive to the warming of the shed, affects the growth and development of eggplant, fruit, melon and vegetables, and significantly increases the incidence of diseases. At this time, great attention should be paid to the ventilation and light transmission of the shed 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.Protect flowers and fruits
Low temperature is unfavorable for the results of solanaceous fruits and vegetables, and it is easy to cause abnormal fruit increase and flower and fruit drop. Artificial pollination should be used, or drones should be placed in the shed, or plant growth regulators should be dipped in flowers or sprayed to increase fruit set rate and reduce the proportion of deformed fruits.
4. Prevention and treatment of diseases
Excessive humidity in the shed can easily cause gray mold, etc. Pay attention to ventilation, planted potatoes, soft-cultivated celery, and spinach sowed. After the spring, they should be managed in time. It is also necessary to prevent cataplexy, blight, root rot, downy mildew, anthracnose and tomato gray mold, early blight, eggplant brown spot, lettuce downy mildew, sclerotinia, celery spot Blight, etc .; pay attention to control aphids.
