Nursery: Use a plug or nutrient cup to select a seedbed with good ventilation, heat preservation, moisturizing, and fertilizer retention, such as peat soil. The optimum temperature for germination is 25 degrees, generally 3-4 days after emergence, maintained at 23-28 degrees during the day after emergence, and maintained at 16-18 degrees at night.
Planting: Fine preparation before planting, organic fertilizer 5000-7000 kg/mu, diammonium 30-40 kg/mu. Other fertilizers are applied as appropriate according to the soil conditions. Two-row colonization by sorghum is usually adopted, with a density of 2200-2600 plants/mu. About 15 cm in height, 70-80 cm in width, 35-40 cm in spacing, and 50 cm in width. A small ditch is opened in the center of each ridge for the purpose of submerged irrigation under the membrane. After the planting, the larvae are poured to facilitate the development of the root system.
Water and Fertilizer Management: Pour a relatively small sapling water 3-4 days after planting. After watering every time with fertilizer, mu urea 10 kg, every 5-7 days watered once. Foliar spray once a week 0.2-0.3% of potassium dihydrogen phosphate.
Temperature and humidity management: during the melon period 25-30 degrees during the day, humidity 75%; 20 degrees in the afternoon, humidity about 70%; night temperature before midnight at 15-18 degrees, about midnight at 10 degrees, the humidity at night is 80-90%. In Winter, special attention should be paid to proper ventilation to maintain a proper temperature difference between day and night. In case of cloudy days, some melon and female flowers should be removed to inhibit reproductive growth and to save nutrients. In addition, immediately after each watering, the greenhouse can be raised for a period of one hour by closing the shed, and then quickly released and dampened, and repeated two times. This can effectively prevent the condensation of foliage at night and suppress the occurrence of diseases.
Plant adjustment: In the long-period cultivation mode, it is better to use slings, with the main vines as the main, leaving 1-2 melons per section. In order to fully grow and develop the root system, the female flowers in the first 5 nodes should be firmly rejected. The cranes work three times every two weeks and are scheduled to take place in the afternoon because the morning plants are high in moisture and relatively young and easy to break. The old leaves are usually 2-3 times a week, arranged in the morning, because the morning after the completion of the pruning, enough time in the afternoon to dry the wound, can reduce the chance of pathogen infection. When removing the old leaves, pay attention to the preservation of the petiole, otherwise the wound is likely to become a breakthrough in disease infestation.
Harvesting: timely harvesting according to species characteristics and market needs. Harvesting is too early, the fruit's ability to hold water is weak, and the shelf life is short. When harvesting is too late, the fruit becomes old and its quality deteriorates. It also consumes too much nutrients and causes the plants to lose their balance of growth. The subsequent fruits are easily deformed or fall.
Pest control: Pests and diseases mainly include downy mildew, powdery mildew, bacterial angular spot and blight. Insect pests include leafminers and aphids. Prevention-based, available 800 times promecarb or cream gram prevention and control of downy mildew; 4000 times streptomycin sulfate or 3000 times Keke Kang prevention and treatment of bacterial angular spot; 6000 times the world high against powdery mildew; occurrence of blight In the seedling stage, the carbendazim solution can be irrigated 5000 times every 7 days or so; when the leaf miner flies, the liquid can be sprayed 2000 times, and when the locust occurs, the liquid medicine can be sprayed 2000 times.
