1. Planting land selection: It is better to choose sandy soil with deep soil layer, loose and fertile soil, good drainage performance and convenient irrigation.
2. Soil preparation and fertilization: After selecting the planting land, it is necessary to trim the field before sowing, and apply high-quality organic fertilizer and cake fertilizer as the main and inorganic fertilizer as the auxiliary base fertilizer.Melon land needs three ditches, digging box ditches, waist ditches and surrounding ditches to improve the drainage and irrigation system of the field.
3. Planting: In the afternoon of the day before sowing, the melon field needs to be watered thoroughly.When sowing, the distance between seeds should be controlled, not too thin or too dense.
4. Pruning and vine pressing: Generally, three-vine pruning is adopted.Pruning should not be carried out in rainy days to prevent infection.When the vines grow to about 50cm, the vines can be pressed by soil at intervals of 3-4 sections, and each vine is pressed for 2-3 times.
5. Topdressing: When the young melon grows to the size of an egg, according to the growth of the plant, it is necessary to apply the puffed melon fertilizer in time.
6. Moisture: The water requirement is low in the seedling stage, so water as little as possible or not, so that the seedlings can form a developed root system.The amount of water should be controlled before flowering and fruit setting to prevent wild growth; After fruit setting, adequate water supply should be guaranteed to help the fruit expand and increase its weight.
The planting time is determined according to the early-maturing or late-maturing watermelon varieties.Early-maturing watermelons can be sown from mid-December of last year to March of next year, and the fruit ripening period is about March to June.Medium-ripening watermelons can be planted from April to June, and the fruit period is from July to September.Autumn watermelons need to be sown in the middle and late July, and can be harvested in late September.
