What to pay attention to in vegetable management during frost season

Frost and solar terms are coming, which means that winter is not far away. At this time, the weather is getting colder and the first frost appears. The cold wind seems to be the main melody of the climate. In the frost-fall season, for vegetable planting managers, it is necessary to make relevant measures to deal with the coming of frost-fall.

Camomiles Vegetable Management

1, Chinese cabbage chopped vegetables in time to prevent freezing

During the frost, autumn sowing Chinese cabbage is about to be harvested. At this time, the watering management in the later period should be strengthened. Generally, watering is carried out every 5-7 days. It is required that the amount of water is uniform to prevent flood irrigation. Stop irrigation 7-10 days before harvesting. Chop the vegetables in time before the temperature drops to 0 ℃ to prevent freezing.

2. Autumn greenhouse vegetables strengthen insulation and cold protection

Tomatoes, cucumbers, eggplants, peppers and other thermophilic crops need to strengthen heat preservation and cold protection, such as closing the strict air vents at night, a grass curtain around and other measures must be in place at all times. And celery, lettuce, rape, spinach, radish and other cold-resistant vegetables need to be watered and insect-resistant.

Key points of frosting vegetable management

3. Fine management of eggplant and fruit vegetables

Tomatoes, eggplants, peppers, and other crops in the solar greenhouse in autumn and winter and overwintering are in the flowering and fruiting period during the frost season. Management should be strengthened to promote more fruit with a higher commodity rate. After slow seedlings, watering squatting should be controlled, and cultivating 1-2 times when the conditions are suitable to promote root growth, and at the same time appropriately reduce the temperature in the shed, so that the temperature in the greenhouse during the day is maintained at 23 ℃ -28 ℃, night at 15 ℃ or so. The indoor relative humidity is adjusted according to different crops. Tomatoes and eggplants are 45% -50%; sweet peppers and cucumbers are 60% -80%.

4. Overwintering stubble vegetables pay attention to seedling management

Overwintering stubble vegetables such as spinach and shallots are at the growth stage of the seedlings. Watering, fertilizing, and cultivating loose soil should be timely to promote healthy plant growth and developed root systems, which are conducive to safe wintering.

5. Harvest radishes and shallots in time

In the frost season, even cold-resistant green onions can no longer grow, and radishes and carrots have basically stopped growing, so they must be harvested in time to prevent freezing damage and affect their commerciality.
