Cultivation Techniques of Cucumber in Greenhouse

The sowing period of greenhouse cucumbers can be from late December to mid-January, and greenhouses should be used for raising seedlings with small sheds (or electric hotbeds for greenhouses). Seedling age 40-45 days, sowing rate of about 0.1 kg per mu. The seeds were soaked in clean water and put in hot water at 55°C. The amount of water was 3 to 4 times that of the seeds. Stir constantly. When the water temperature dropped to about 30°C, soak at room temperature for 1-2 hours. stand-by. The plots that have not been planted with melon crops in recent years are selected as seedbeds, and the beds are leveled and soiled with water, and planted after 24 hours. From sowing to cotyledon unearthing, it is necessary to maintain a high temperature. When the temperature of the greenhouse reaches 15°C, the apron is applied to the greenhouse. When the temperature reaches 10°C, the small arch shed starts to cover the straw. The specific temperature requirement is to maintain 25°C-30°C during the day and 20°C at night. After the seedlings are unearthed, the temperature is appropriately lowered. The temperature is about 25°C during the day and about 16°C at night. 4 to 5 days after sowing, the seedlings will be transplanted into the nutrient bowl, transferred to the live tree before transplanting, suitable high temperature and humidity, keep the seedbed within 25-30 °C, 3-4 days after the gradual cooling, control during the day at 20-25 °C, 14 at night -16°C to prevent leggy. Seedling soil is often kept moist, watering should be selected to be sunny, can be combined with 0.2% potassium dihydrogen phosphate +0.2% urea topdressing, adequate ventilation after application, promote strong seedlings.
