Early winter vegetables
The "starting winter" solar term is the 19th solar term for the lunar calendar. After the beginning of winter, it begins to enter the winter. The temperature drops sharply and it becomes colder. The daily sunshine time is getting shorter. Vegetables grown in greenhouses have been shriveled. For cold-tolerant leafy vegetables, we must seize the opportunity to manage well before harvest. Autumn and winter vegetables grown in sunlight greenhouses are in a period of vigorous growth. We must strengthen management and prevent cold. Antifreeze work. Pulling vegetables in autumn greenhouses and harvesting of thermophilic crops such as tomatoes, cucumbers, peppers, and eggplants grown in autumn greenhouses should be timely plucked, and the unripe tomato fruits can be stored in the greenhouse for ripening; Spinach, lettuce and other crops should be well-preserved insulation and antifreeze work, at night in the greenhouse to cover a one-meter high straw insulation, and timely harvest in the best commodity period. The cold-proof and heat insulation of the solar greenhouse shall carefully analyze the thermal insulation performance of the greenhouse, and adopt measures of insulation and cold-proofing for the weak parts. After the rear window and exhaust fan with foam board, straw curtain and other materials sealed; door installation of cotton curtains, greenhouse entrance with agricultural film set 5 meters long windshield; to fill the cold trench into the straw, leaves and other insulation Materials; the front roof of the shed is covered with a 100 cm-high agricultural film to prevent cold; the overlying slope is covered with 2-3 layers of straw or old insulation; the back wall is soiled or covered with old straw to increase Insulation, two layers of agricultural film or non-woven fabrics are installed in the shed at night. Greenhouse vegetable management For greenhouse tomatoes, cucumbers, eggplants, sweet peppers and other autumn and winter pods and warm crops such as autumn and winter, we must adjust the temperature, light, air humidity and other environmental conditions, especially to increase the light, we must often scrub the shed film, increase penetration Light rate; timely ventilation and ventilation, strengthen pruning, auxiliary pollination, thinning and fruit thinning, scientific top dressing, watering, and timely management of pests and other management, to promote plant growth robust, multi-results, fruiting results. Cold-adapted crops such as celery, rapeseed, and radish should be well managed to regulate the environment, cultivating loose soil, and top-dressing and watering. Clean the pastoral and cultivate the land with open-weather thermophilic vegetables, such as tomatoes, cucumbers, peppers, eggplants, potatoes and other crops. Early harvesting of the plants and roots in the ground and centralized high-temperature composting or ozone disinfection are harmless. Processing. Plowing the land before freezing, on the plots of the city's windward mouth, it is possible to plant overwintering root leeks or rapeseeds to prevent the formation of dust on exposed land and to avoid polluting the urban air. The management of open-rooted leeks exposes overwintering root vegetables such as spinach and shallots in winter, and they should be watered and topdressed in time to promote robust plant growth and facilitate safe wintering. Watering should be the most suitable time for "night freezing and depleting" (ie, freezing ice at night and opening during the day). Youth Biotech CO,. Ltd. , https://www.youtherb.com
