1. Soil preparation for fertilization and soil preparation One week before planting, 3000 to 4,000 kilograms of high-quality rotten farmyard fertilizer per acre, 50 kilograms of diammonium phosphate, 30 kilograms of potassium sulfate, and 50% phoxim 1 kg to treat the soil, deepen after fertilization The ridges were ridged, widened and narrowed, ridge width 70 cm, ridge distance 80 cm, ridge height 20-25 cm, and covered with mulching.
2. The appropriate physiological seedling age for colonization of melon plants at the appropriate time is generally 3 leaves and 1 heart period. The calendar seedling age is about 30 to 40 days. When planting, it is required that the temperature of 10 cm in the greenhouse be stable at 14°C, the nighttime temperature should be above 13°C, and the Guanzhong region should generally be around mid-January. Select the sunny morning for planting, and the shallow surface should be planted. Centimeter, exposed cotyledons. After planting, use 5000 times neb and transplanting Ling irrigation roots, and cover a small arch shed to promote the slow seedlings.
Second, post-planting management
1. Closed insulation after temperature management is planted to promote easing of seedlings. Maintain 28 to 32°C during the day and no lower than 15°C at night. Relax until the fruit expands to a daytime temperature of 27 to 30°C and nighttime at 18 to 20°C. Fruit enlargement period Keep 28 to 32°C during the day and 10 to 15°C at night to increase sugar content.
2, fertilizer and water management planting 7 to 10 days after the gentle pouring of a gentle seedling water, after tillering cultivator, and cover the film in the ridge to increase the ground temperature, plant height 20-40 centimeters when watering Zhongman water, watering must be in the sunny morning To avoid flooding. In the five days after the opening of the female flower, the irrigation should be strictly controlled so as to prevent stem vines from causing the melons to grow. When the larvae reach the size of the eggs, they should be filled with swelled water, combined with watering to apply 20 kg of urea per mu, 30 kg of diammonium phosphate, and sulfuric acid. Potassium 10 kg, during the expansion of the melon and then sprayed once every 7 days about 0.2% potassium dihydrogen phosphate solution.
3, plant adjustments generally use single vine pruning, plant inverted vines with a plastic rope will be vines hanging, leaving the melon section generally around 14 knots, under which all the side branches should be removed, the main vine grow to 24-26 when playing Top, and take care to remove newly emerging side branches at any time.
4, pollination melon 13 to 16 internodes open female flowers open, selected sunny day at 8: 00 to 10: 00 when artificial pollination, melons grow to walnut large timely when the melon, usually elected to stay in the same size, location, pollination The same time, melon, melon will be removed after the rest of the melon, when the melon grows to the size of the egg, with a plastic rope into a live buckle, pick up the stalk near the fruit part of the melon hanging, hanging melon height should be everything, For management.
Third, timely harvest
Generally based on the number of fruiting days, the time-to-market period is firstly calculated, and combined with individual fruit development characteristics, if the skin displays the inherent color, pattern, reticulate appearance, the surface is shiny, the fruit handle is velvety, the fruit shank is yellow, and the fruit-setting section must be completely dried. Can be harvested.
IV. Pest control
During the seedling stage, it is prone to damping-off. It can be sprayed or rooted with 72% Preclox 1000x. Grow disease and virus disease are easy to occur during the growth period. They can be sprayed with 70% dexamethasone zinc 500 times solution and 200% virus a500 times solution respectively. Bacterial leaf spot and leaf blight are sprayed with 4000 times agricultural streptomycin or 600 times spray, powdery mildew is sprayed with 15% triadimefon 1000°C times or sulfur suspension 300 times, and downy mildew is used 50 times. % Fumei Double 500 times or 70% MnZn Zn 500 times solution. Fusarium wilt is rooted with 90% of dexamethasone or 50% carbendazim 600 times. The locusts were treated with 10% fluocetate 800 times. Leaf miners were sprayed with 20% speed kill 1500 times or 98% Bataan 2000 times.
