Key points of vegetable management and harvest with Frosts Descent's advent of solar terms

Vegetable planting

Frosts Descent is the last solar term in autumn, and it is also the transitional solar term from autumn to winter. With the arrival of the autumn frost, the cold-resistant crops have pulled seedlings or are about to stop growing, and the plants begin to turn yellow. Vegetable production in the open field is coming to an end, and production in protected areas is busy.

Management and harvest of Chinese cabbage

The Chinese cabbage sown in autumn is about to be harvested in the late period of Baoxin. Due to the low temperature from September to October this year, the encase is relatively slow, so it is necessary to strengthen the late watering management to keep the soil moist. Generally watered every 5-7 days, the amount of water is required to be uniform, prevent flooding, and stop irrigation 7-10 days before harvest. Cut vegetables in time before the temperature drops to 0 ℃ to prevent freezing. The general plain area is from November 3 to 7, Yanqing, Huairou and other northern mountain areas should be 5-6 days in advance according to climate change.

Management of greenhouse vegetables in Autumn

Tomatoes, cucumbers, eggplants, peppers and other temperature-loving crops should strengthen heat preservation and cold protection, close strict tuyere at night, a grass curtain around, and timely watering and timely harvest. The tomato fruits that can not change color should be harvested in time when the temperature drops to more than 5 ℃ and ripened in greenhouse or idle houses with higher temperature. Cold-tolerant vegetables such as celery, lettuce, rape and radish should strengthen the management of watering and insect control.

Planting and management of vegetables in solar greenhouse in autumn and winter

Cucumber, zucchini and other melon crops in overwintering stubble are in the right planting period, fertilizing and soil preparation should be done 10 days in advance, and planting in sunny days should be selected to ensure proper shallow planting, suitable density and adequate planting water in time. Tomato, eggplant, pepper and other crops in autumn and winter are in blossom and fruiting period. it is necessary to strengthen the management of ploughing and loosening the soil, binding vines around vines, pruning branches, auxiliary pollination, thinning flowers and fruits, watering and topdressing, so as to promote more fruits with high commodity rate.

Management of overwintering stubble vegetables

Spinach, spring onions and other overwintering root stubble vegetables are in the seedling stage, so they should be watered and fertilized in time to promote plant growth and be conducive to safe overwintering.

Harvest of radish and green onion

Frosts Descent season, most parts of the north have finished the autumn harvest, even if the cold-tolerant crop green onions, can no longer grow, because "Frosts Descent can not afford green onions, the longer the more empty"; radishes and carrots also basically stop growing, so it is necessary to harvest in time to prevent freezing damage and affect its merchandise; green onions can not be sold for a while, stored in places with low temperature and avoiding light. After twisting off the tassel, the radish covered the rhizome with the tassel, dug the cellar in the appropriate place, and stored in the cellar when the outside temperature dropped below 0 ℃.

Clean the countryside and plough the land

After the harvest of temperature-loving vegetables in the open field, such as tomato, cucumber, pepper, eggplant, potato and other crops, the plants and stubble in the field should be harvested as soon as possible and concentrated on harmless treatment such as high-temperature composting or ozone disinfection. Ploughing the land before freezing can plant overwintering stubble vegetables or rape in the land of the upwind of the city, so as to prevent the land from being exposed to form dust and avoid pollution to the urban air.
