What matters should be paid attention to in vegetable management during frost season

The frosty solar term is approaching, which means that winter is not far away. At this time, the weather is getting colder, the first frost appears, and the swishing cold wind seems to be the main melody of the climate. During the frost season, vegetable planting managers must take relevant measures to deal with the arrival of frost.

Frost vegetable management

1. Cut Chinese cabbage in time to prevent freezing

During the frost, the autumn sowing Chinese cabbage is about to be harvested. At this time, the later watering management should be strengthened. Watering is generally done every 5-7 days, and the water volume is required to prevent flooding. Stop irrigation 7-10 days before harvesting. Cut vegetables in time before the temperature drops to 0°C to prevent freezing.

2. Autumn greenhouse vegetables strengthen heat preservation and cold protection

Temperature-loving crops such as tomatoes, cucumbers, eggplants, and peppers should be strengthened to keep warm, such as closing the wind vents at night, and a grass curtain around them, etc., must be in place at all times. For cold-resistant vegetables such as celery, lettuce, rape, spinach, and radish, watering and pest control should be strengthened.

Essentials of Frost Vegetable Management

3. Fine management of solanaceous vegetables

The crops such as tomatoes, eggplants, and peppers in solar greenhouses in autumn and winter and overwintering are blooming and bearing fruit during the frost season, and management should be strengthened to encourage more fruits with high commodity rates. After slowing the seedlings, control the watering and squat seedlings, and cultivate 1-2 times when the moisture content is suitable to promote the growth of the root system. At the same time, reduce the temperature in the greenhouse appropriately to keep the temperature in the greenhouse at 23℃-28℃ during the day and 15 at night. ℃ around. The indoor relative humidity is adjusted according to different crops, with tomatoes and eggplants at 45%-50%; sweet peppers and cucumbers at 60%-80%.

4. Overwintering root stubble vegetables pay attention to seedling management

Overwintering root stubble vegetables such as spinach and shallots are in the seedling growth period. Watering, top dressing, and cultivating soil should be timely watered to promote healthy plant growth and a well-developed root system, which is conducive to safe overwintering.

5. Timely harvest radishes and green onions

During the frost season, even cold-resistant green onions can no longer grow, and radishes and carrots basically stop growing, so harvest them in time to prevent freezing damage and affect their commercial properties.
