Early spring greenhouse cultivation, sowing in mid-to-late January, seedling age 35 to 40 days. The seedlings are warmed up, planted in the shed in the middle of March, and covered by the "three membranes" (large shed, small arch shed, mulch), which was launched in early May. In the spring, the small arch shed is covered and cultivated. In the second half of February, the greenhouse is planted. The geothermal line is heated and nursed. The seedling age is about 35 days. It is planted in early April, covered with plastic film, covered with small arch shed, and listed in mid-June. It is cultivated in summer and autumn, and is planted in the middle and late June to mid-July. The seedling age is about 20 days, and it is listed from late August to mid-September.
Site preparation
Choose soil fertile, rich in organic matter, convenient irrigation and drainage, 4 to 6 years have not planted the field of melons, deep ploughing for more than 30 days, the whole fertilization. The width of the raft is 2.5 to 3.5 meters, the width of the groove is 30 centimeters, and the depth of the groove is 30 centimeters. The middle of the face is high, low on both sides, and is turtle-shaped, planted in two rows or in a single row. 3000 kg of farmer's fertilizer and 40 kg of potassium sulfate compound fertilizer per mu are used as base fertilizer.
Soaking seeds
After soaking in cold water for 8 to 10 hours, wash it, remove the mucus, wrap it with a wet towel, and place it at a constant temperature of 28 to 30 °C to germination. More than 70% of the seeds are white and can be sown.
Seedbed temperature management
Do not peel off the film easily before emergence. The bed temperature on sunny days is higher than 40 °C, and the two sides of the shed film are opened to cool down. When the temperature drops to 30 °C, it is covered. The temperature is maintained at 30 to 35 ° C during the day and 15 to 20 ° C at night. After the emergence of the seedlings, keep 25 to 30 ° C during the day and 18 to 20 ° C at night. After the melon seedlings are exposed to the leaves, the temperature should be raised while maintaining the humidity but not too wet, otherwise it is easy to develop. Watering is carried out in the morning on a sunny day. When the seedlings have 2 to 3 true leaves, the low temperature refining seedlings are 5 to 7 days for transplanting.
Colonization
When the melon seedlings have 3 to 4 true leaves, they are transplanted into the field, with a plant spacing of 45 cm and about 500 plants per mu. Immediately after planting, the root water is poured, and the hole is fixed with the soil seal and the film is sealed, and then the small arch shed is covered.
Field management
10 to 15 days after planting, when the vine grows to 30 to 50 cm, it is pressed with clods on a sunny afternoon, and then every 7 to 8 leaves are pressed once. When pressing the vines, under the melons in the position of the female flowers, use the grass to pad the melons, and then press the vines in front, so that the female flowers are higher than the ground, which is convenient for sitting. Look at the seedlings and dressing water, avoid excessive soil moisture and excessive nitrogen fertilizer. The melon section can be selected from the second to third nodes of the main vine, and the second section of the side vine, each plant chooses 2 to 3 melons. Re-applying the expanded melon fertilizer is the main measure to increase the yield. When 70% of the melon has the size of the egg, the fertilizer is applied. The fertilizer is applied at a distance of 30 to 50 cm from the root of the plant, and 10 to 20 kg of urea per acre is applied. ~ 20 kg, 30 kg of decomposed vegetable cake fertilizer, after pouring fertilizer, according to the weather conditions, pouring enough water to expand the melon. After the water in the field is dried, the leaf surface sprays the farm music and the rich boron, which can achieve the effect of promoting the expansion of the melon.
Pest control
The main diseases are anthracnose, blight, blight, etc., pests are aphids, yellow guards, etc., should be timely prevented.
