Sunlight greenhouse and small sheds
Tomatoes, cucumbers, eggplants, and other thermophilic crops grown in the solar greenhouse must use high-insulation, high-temperature insulation, dripping anti-fog membranes, or EVA agricultural film. Planting aubergine greenhouses should not use polyvinyl chloride film. Planting greenhouses such as tomatoes, cucumbers, peppers, eggplants, and other thermo-vegetable greenhouses to stay up and down two tuyere, that is, covering the three films of the greenhouse, is conducive to the growth of the crop. When the outside temperature is lower than 15°C, grasshoppers or insulation are timely. After the greenhouse buckle film should pay attention to ventilation, prevent high temperature emergence leggy seedlings. The celery planted in open field can be insulated by deducting a small shed to cover grasshoppers, which can be delayed for 1-2 months.
Sunlight greenhouse cucumber and summer squash colonization
Greenhouse with medium insulation performance (insulation effect around 20°C, ie outside minimum temperature in winter -15°C, shed temperature up to 5°C) planted in early October; greenhouse with good insulation properties (insulation effect at 25°C The above, that is, the minimum temperature outside the winter at -15 °C, the temperature within the shed can reach 10 °C or more) can be postponed until the late 10 to early November, planting, overwintering growth supply the New Year's Day, the Spring Festival and the coming spring market supply, to make a good shed in advance Room disinfection and soil preparation fertilization, the use of high-quality organic fertilizer more than 5000 kg per acre, planted in the sunny afternoon, so that the same depth, the density is reasonable.
Solar greenhouse vegetable management
Early colonization of tomato, eggplant, pepper and other thermophilic crops has entered the flowering and fruit setting period, to adjust the appropriate temperature, light and moisture growth environment; timely hanging vines, tied vines, pruning; timely watering, top dressing, tomato , Eggplant timely to adopt auxiliary pollination measures to promote fruit set, and early sparse excess fruit and deformed fruit; prevention and control of pests and diseases, especially to focus on the prevention of tomato yellow leaf curl virus disease, pepper disease, stem rot, eggplant Verticillium wilt occur.
Greenhouse Vegetable Management and Harvesting
Greenhouse tomatoes, cucumbers, eggplants and other thermophilic vegetables have been harvested in the middle and late stages of fruit harvesting, and they must do a good job of regulating temperature and heat preservation and cold protection. In cold weather, they can be insulated by grasshoppers or straws around the night. Timely watering and foliar spray to promote growth. Harvest fruit in time to prevent falling. Cold-tolerant vegetables such as celery and lettuce are in their infancy, and watering, top-dressing and pest control work must be strengthened.
Exposed vegetable management and harvesting
Chilling crops such as cucumbers, legumes, and eggplants grown in the open field have ceased to grow, and they must be plucked and unloaded as early as possible; for the cabbage, radish, carrots, cabbage, cauliflower, lettuce and other cold-resistant vegetables, it is necessary to strengthen management, timely watering, and dressing And control pests and diseases. In particular, the radish should be evenly watered, with emphasis on the prevention and control of pests such as Brassica napus, Spodoptera littoralis and other pests. It has a good control effect at night or early morning. Precocious vegetables such as cabbage and rapeseed, garland chrysanthemum, lettuce, spinach, cilantro, celery, radish, etc., have been able to be harvested in succession and harvested in the best commodity period.
Scallion harvesting
In order to harvest the scallions early in October, if they harvest too late, it will affect their commodity nature. There is a farmer saying “August onion is empty in Septemberâ€. Therefore, according to the market demand in time to harvest and sell, can not be sold for a time, you can use storage to increase the selling price.
