I. Land consolidation
Choose plots with sufficient light, convenient drainage and slightly higher terrain for planting. Before planting, the soil should be prepared, turned over once, and base fertilizer should be applied to the plot, and 2000 kg of decomposed farmyard manure, 20 kg of ammonium nitrate and 25 kg of calcium superphosphate should be applied per mu.
Second, the sowing method
In order to make Hami melon seeds germinate better and emerge faster, it is suggested to soak seeds in advance to accelerate germination. Sowing should be carried out when the soil temperature is stable above 65438 04℃ and suitable for management. Usually it is directly drilled. If it is an early and middle mature variety, single vine pruning should be carried out according to the plant spacing of 45 cm; If it is a mid-late maturing variety, double vine pruning should be carried out according to the plant spacing of 60 cm, and the sowing depth should be about 3-4 cm.
Third, seedling management.
If the planting method is proper and the climate is suitable, Hami melon seeds will germinate and emerge soon. Three days after emergence, you can check the seedlings and replant them. Generally, when the seedlings grow to 1-2 true leaves, they should be thinned, leaving only two seedlings in each hole. Seedlings should be fixed when 4-5 real leaves are used, and seedlings should be reserved for each hole 1 plant. When the seedlings grow 5-6 true leaves, it should be reversed.
Fourth, fertilization management.
Before the opening of Hami melon female flowers, 20 kg of calcium superphosphate, 5 kg of urea and 0/50 kg of oil residue/kloc were applied per mu. After the first fruit harvest, 200 grams of potassium dihydrogen phosphate and 300 grams of urea should be applied to prepare a low-concentration fertilizer solution and sprayed.
Verb (abbreviation of verb) environmental management
Hami melon likes warm environment. Before emergence, the temperature should be controlled at 30-32℃ during the day and at 18-20℃ at night to promote full emergence. The temperature should also be kept at 28-32℃ after spreading leaves. In addition, water should be strictly controlled at seedling stage, as long as the soil is slightly wet.
Quality characteristics of Hami melon
Hami melon is an annual creeping or climbing herb with angular stems and branches, yellow-brown or white coarse hairs and warty protrusions. Tendrils are slender, simple and puberulent. Petiole is 8- 12 cm long, with grooves and short bristles; Leaf blade is thick papery, nearly round or kidney-shaped, 8-15cm in length and width, rough at the top, rough and white at the back, thick and dense along veins, undivided or 3-7-lobed at the edge, blunt at the top of lobes, serrated, truncated or semicircular at the base, palmately veined.
Flowers are unisexual and hermaphroditic. Male flowers: several flowers are clustered in the axils of leaves; Pedicel slender, 0.5-2 cm long, pilose; Calyx tube narrowly campanulate, densely white villous, 6-8 mm long, lobes nearly erect or spreading, shorter than tube.
Corolla yellow, 2 cm long, lobes elliptic, acute; Stamens 3 mm, filaments extremely short, anthers curved, connective tips elongated; The degenerated pistil is about 65438 0 mm long. Female flowers: solitary, with rough pedicels and pilose; Ovary oblong, densely villous, with coarse hair, style length 1-2 mm, stigma near, about 2 mm long.
