Construct a high-quality winter-style greenhouse and adopt various measures to increase the temperature. The structure of the greenhouse is firm, and the lighting and heat preservation performance are good. It is the guarantee for winter cucumbers. Under construction, 1.2 to 1.5 meters of digging is used, the width of the back wall is 2 meters at the top, and the thickness of the rear roof is no less than 30 cm.
I. Variety selection Winter-winter greenhouses Cucumber varieties are required to be resistant to low temperature and low light, root melons are good in section, and melon strips grow rapidly under low temperature conditions.
Second, grafted seedlings, nurturing strong seedlings
1. Seeding period: The stock of pumpkin is selected from No. 1 squash anvil, and the appropriate sowing date is in late August. The cucumber is sown 3 days earlier than the rootstock.

3, grafting method: using the connection method or connection method.
4, after grafting management: (1) moisturizing: after grafting a small arch shed, 2-3 days to cover tight, can not ventilate, maintain a certain humidity. (2) Temperature control: The suitable temperature for the healing of the cucumber interface is 25°C and does not exceed 30°C. (3) Ventilation: Ventilation starts after grafting for 3 to 5 days. The initial ventilation is small and gradually increases. Generally, ventilation is performed after 9 to 10 days.
Third, colonization
Select low light when the afternoon light when the colonization, with roots and other agents to prevent root diseases. Two rows per plant. The average row spacing is 65 cm, the spacing is 33 cm, and the density is 3100-3200. Timely pouring slow water.
IV. Management after planting
1, temperature management: colonization to hair tree. To promote root-based, during the day 25 ~ 30 °C, no less than 15 °C at night, after the gradual ventilation and cooling. After the winter and cold seasons occur, the temperature is controlled at the lower limit of temperature as the weather changes. After late February, the temperature gradually warmed up, and the cucumbers entered the period of melon growth. The temperature did not exceed 30°C during the day and 12°C to 14°C during the night.

Appropriate application of phosphate fertilizer and various trace fertilizers are available. In terms of water management, from the time of planting to the deep winter season, the control is mainly based. In late February, the temperature rises, the water requirement of cucumbers gradually increases, and the amount of watering can be appropriately increased, and the ventilation and dehumidification can be enhanced after watering.
V. Pest Control
1. Insect pest control: The locusts are treated with the schistosomiasis or the net insecticide of the aphid, and the whitefly can be trapped with a yellow plate, or they can use a sweep of light and other agents.
2. Disease prevention and treatment: downy mildew 5 to 7 days with 50% of Eubacteria WP 600 to 800 times and 80% of lyophobic 1200 to 1800 times to prevent bacterial bacterial leaf spot And downy mildew. Powdery mildew is treated with 60% of Starac Powder WP.
