1, choose a good variety of fresh cucumber should choose sweet crisp green 6, Chunguang 2, No. Daiduo and other varieties, with 50-70 grams per acre species.
2. Appropriate growing environment Fresh cucumbers are not too cold tolerant to cold, the most suitable growth temperature is 25°C-30°C during the day and 15-18°C during the night. Wet and wetness requires high air humidity and soil moisture. Combined environment: suitable for soil deep, loose and fertile soil cultivation, the need for fertilizer, should be combined with nitrogen, phosphorus, potassium, trace elements in conjunction with the application; need a strong light, suitable for protective cultivation.
3, cultivation season Spring sorghum cultivation generally 1-2 month nursery, 2-3 months planting, 3-7 month harvest.
4, the cultivation of seedlings 55 °C warm soup soaking, with peat as a substrate, nutrition seedlings nursery. After germination, freeze at a low temperature for 24-48 hours at -2°C-2°C, then adjust the temperature to 25-30°C to maintain strong light. Seedling age 25-35 days, when 3 leaves and 1 heart reached the standard of strong seedlings, dark green leaves, well-developed root system and no pests and diseases.
5. Fertilization for soil preparation Apply 3,000 kg of decomposed organic fertilizer or 400 kg of active organic fertilizer per acre, plough depth 25 cm, turn 2-3 times to fully mix fertilizer and soil. Do the Yangshuo 20-30 cm above the ground and cover the pellicle.
6, timely planting temperature stability can be planted at 15 °C above, row spacing of 90-100 cm, 1.8-1.9 m planting two rows, can also be planted alone, spacing 35-40 cm, 1700-2000 per mu. Select sunny planting.
7, field management 1 watering. Seedlings are sown 5-7 days after the seedlings are soaked, and the soil is poured afterwards, often keeping the soil moist. 2 top dressing. After harvesting melons, apply active organic fertilizer once every 10-15 holes and 100 kg per mu. Foliar application of 3-4 times potassium dihydrogen phosphate. 3 plant adjustments. From the beginning of the 6th to stay in the melon, l-5 section melon should be dredged as soon as possible, do not insert the frame, use the rope to hang the vine to fix the plant, the middle of each section can stay l-2 melons, branches left a melon after the top. When the plant grows to the height of the shed, the lower old leaf is destroyed and the wire rod sits down. 4 adjust the temperature. Strengthen ventilation, daytime 25 °C -3O °C, night 15 °C -18 °C, ground temperature 21 °C, winter to increase greenhouse transmittance. 5 timely prevention and treatment of diseases. Use broad-spectrum fungicide when spraying, such as 43% Halic (Bayer, Germany) to control powdery mildew and anthrax; use 50% Anke (BASF, Germany) to control downy mildew and disease; 53.8% can kill 2000 plus Yunda 120 or agricultural streptomycin plus 72% Best, which can prevent bacterial keratoses.
8, timely harvest melon 13-18 centimeters in diameter up to 2-3 centimeters, flowers can be harvested when they begin to thank. Cut off the stalks with a knife and gently handle them. The weight of a single squash is about 80 grams. Each pod can have 20 to 30 knots and produce 3,000 to 4,000 kilograms per mu.
