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, the following agricultural activities should be focused on. 1. Choose a place that is sheltered from the wind and the sun and the terrain is high and dry, and make a seedbed to be a seedling place for spring sowing and warm vegetables. 2. After the previous crops are harvested, promptly remove the stumps and old leaves in the field, eradicate the weeds in the corners of the field, concentrate fertilizer or destroy, and eliminate the source of insects. 3. The base fertilizer should be fully decomposed farmyard manure or organic fertilizer. When topdressing, use less chemical nitrogen fertilizer, increase phosphorus and potassium fertilizer, and enhance cold resistance. 4. When eggplant and pepper seedlings have 1 to 2 true leaves, take full advantage of light and heat resources, seize favorable opportunities, and transplant them to facilitate survival. 5. Chinese cabbage with a strong core should be harvested in time; if the core is not yet solid, the leaves should be bundled, and water and fertilizer management should be strengthened to promote the core. 6. For lettuce cultivated early, mulch it before planting, and then open holes for planting. In cold weather, it is also necessary to cover with shed 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 blowing over, and do a good job of heat preservation and cold protection. 8. For the over-wintering vegetables planted in branches, a certain amount of row spacing can be reserved for interplanting the next year's spring crops, increasing the multiple cropping index and improving the utilization rate of the land. 9. After the planted onion and cabbage are slowly seedlings, the water and fertilizer management should be appropriate and not too much. Otherwise, the seedling plants will be too large to overwinter, and they will be vulnerable to 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 it is still necessary to strengthen prevention and control. For 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.
