1. Select the plots after harvesting the previous crop and combine the fertilization with ploughing and soil preparation.
2, select the good varieties of early spring should choose the melon varieties Yilishabai, Jinyumi and so on.
3. The suitable sowing date for sowing is from mid-December to late January, and the planting is from late January to late February.
4. Before planting seedlings, seedlings should be covered with strict membranes. The temperature of the seedbed should be higher. The temperature should be maintained at 28-32°C during the day and the temperature should not be lower than 17°C during the night. After emergence, the seedbed temperature can be appropriately reduced to prevent seedlings from growing indefinitely. The temperature during the day is maintained at 22 to 25°C and the minimum temperature at night is 15°C. After the true leaves are exposed, the bed temperature can be appropriately increased, maintained at 25-28°C during the day, and the minimum temperature at night is not lower than 17°C.
5, appropriate planting thick melon seedlings age about 30 days, physiological seedlings 3 leaves 1 heart. When planting, it is required that the temperature of 10 centimeters in a greenhouse or a greenhouse be stably passed through 14°C. Colonization should be selected sunny morning without wind, open hole planting, open a hole depth of about 15 cm, watering the hole, the water seepage into the hole when the seedlings into the hole, set after 2 hours to be hot and then cover soil level points.
6, water management after planting a strict cover film, increase the temperature of the greenhouse, and promote the slow seedlings. After 4 to 5 days, the leaves of the seedlings turn green. Select sunny days along the small ridge ditch irrigation, the two small ridge tops, seedling roots run through, but can not let the water diffuse ridge roof. Then cultivating loose soil several times to promote its hair roots. After planting as much as possible to improve the temperature of the greenhouse to ease the seedlings, after the slowing seedlings maintained during the day 25 ~ 28 °C, 6 ~ 18 °C at night, over 30 °C when the film can be properly released. After sitting on melons, the temperature during the day is 28-32°C, does not exceed 35°C, and nighttime is 15-18°C. Maintaining a temperature difference of 10-13°C between day and night is conducive to fruit enlargement and sugar accumulation.
7. When topping the seedlings with 4 to 5 leaves at the right time, take care of the leaves, and choose to keep the healthy Zhuangzi vines to grow. The vines were hung on a scaffold with a nylon rope. In addition to retaining the vines, the remaining cranberries were removed in time. The vine spreads 25 to 30 leaves when it is picked. Heart-pickup should be carried out as soon as possible to prevent excessive wounds. The main plucked hearts should be removed before the leaves are unfolded. As a result, the seed vine or the cranberry must be picked before the flower buds are opened to promote fruit set and fruit hypertrophy. If there are no female flowers on the vines, female withered flowers or female flowers with dysplasia, all should be removed early.
8, the right amount to stay Guaigua melons have a single layer and two ways to stay in the melon. The monolayer stays with melons in the main vine 11-15. The double-layered melon remains on the basis of the single-layered melon, leaving the second melon at the main vine 20-25. The melons left by each strain should be on the same or similar nodes as far as possible, so that the results and the time of harvesting and listing will be concentrated. After 5 to 10 days of fruit setting, such as the size of the egg, select the right shape of the fruit to leave, and remove the excess fruit.
The single layer single vine pruning leaves only one melon per plant, the double fruit of the small fruit leaves two melons per plant, and the large fruit variety only leaves one melon per plant. The melons of each strain should be the same or similar. Excessive fruit is too small, poor quality, messy network, affect the quality. When the young larvae grow to 0.25 kg in time before hanging the melon.
9, prevention and treatment of pests pruning should be carried out in sunny days, and appropriate spraying of agricultural streptomycin to prevent wound infection.
Root diseases: Fusarium wilt, blight can be used 50% carbendazim 1000 times.
Bacterial diseases in leaves: Streptomycin sulfate 5000 times can be used.
Fungal diseases: leaf blight, anthracnose, downy mildew can be controlled with 50% mancozeb 500 times solution and 70% thiophanate-methyl 700 times solution.
Virus disease: When it occurs, 72% of epidemic Bifidobacterium 1000 times can be used to increase the harvest number by 800 times and enhance plant resistance.
