After the beginning of winter, the first frost comes, sunny, more rainy, and strong cold air often causes strong winds and rapid cooling. The open-field vegetable cultivation has ended. You should seize the fine weather and rush to plant over-wintering vegetables.
Farming reminder According to the climate characteristics of this month, we should focus on the following farming activities.
1. Choose well-sheltered and sunny areas and high-dry areas, make seedbeds, and use them as seedling places for planting warm-loving vegetables in spring.
2. After the previous crops are harvested, the stubble and old leaves in the field should be removed in time, the weeds in the corners of the field should be eradicated, and the fertilizer should be concentrated or destroyed to eliminate the insect source.
3. The base fertilizer should be fully decomposed farmyard manure or organic fertilizer. When topdressing, it is necessary to apply less chemical nitrogen fertilizer and increase phosphorus and potassium fertilizer to enhance the cold resistance.
4. When eggplant and pepper seedlings have 1 to 2 true leaves, it is necessary to make full use of light and heat resources, seize favorable opportunities, and transplant them to facilitate survival.
5. The Chinese cabbage with strong core should be harvested in time; if the core is not yet solid, the leaves should be bundled and the water and fertilizer management should be strengthened to promote the core.
6. For lettuce grown in early maturity, mulch is laid before planting, and then planted with holes. In cold weather, it is also necessary to cover with plastic film to prevent freezing.
7. All kinds of vegetables grown in the shed should be covered with multiple layers, and the surroundings should be pressed tightly to prevent the strong wind from turning over, and do a good job of heat preservation and cold protection.
8. For the overwintering vegetables planted in branches, a certain amount of row spacing can be reserved for interplanting the next year's spring crops to increase the multiple crop index and improve the utilization rate of the land.
9. After planting onion and cabbage slow seedlings, water and fertilizer management should be appropriate and not too much. Otherwise, the seedling plants will be too large to survive the winter, and they will easily suffer low temperature and pass through the vernalization stage, leading to early bolting the following year.
10. As the temperature drops, most pests and diseases have also decreased, but prevention and control are still needed. For the aphids that damage the cabbage heart, 40% dimethoate is used to pick and cure. For the yellow striped beetle, 90% trichlorfon and 10% beta-cypermethrin should be used for control, and it can also control other sporadic pests. For the vegetables cultivated in the shed, insect-proof nets should be installed at the two entrances to prevent the invasion and reproduction of various pests.
