Scope

Main Technical Content: 3. Planting Environment: The Hetao Irrigation Area has flat terrain. According to the environmental monitoring conducted by the environmental monitoring department commissioned by the provincial green food management authority, the environmental quality of the production area should meet the requirements of NY/T 391. 3.1 Requirements for Soil Conditions in Greenhouses: - The melon fields should not have been replanted for 3–5 years. - The soil layer should be deep, with medium fertility, and a pH value of 7.5–8.5. - The soil texture should be loamy or sandy loam, meeting the standards of GB 15618 for soil environmental quality. - The greenhouse should have good insulation performance, ventilation, and lighting. The minimum temperature required for watermelon growth is 10°C, and the optimum temperature range is 25–30°C. The effective accumulated temperature during the entire growth period should be 2,500–3,000°C. 4. Seedling Preparation 4.1 Preparation Before Seeding: - Early spring sowing: Sowing typically occurs from mid-December to mid-January, with seedlings taking 35–40 days to mature. - Autumn-winter sowing: Sowing typically occurs from late July to mid-August. - Bed preparation: Level the land in the greenhouse and establish a bed that is 1–1.2 meters wide and 20 cm high. Cover the bottom with 1–2 cm of sieved fine soil, smooth it, and lay a geotextile membrane on top. Install geothermal heating cables with an 8–10 cm spacing and connect them in series. Cover the cables with 2 cm of sieved fine soil before placing seedling trays or nutrient pots. - Seedling trays: Use 50-hole trays filled with substrate soil. Press the holes to a depth of 0.8–1 cm. - Substrate preparation: Use high-quality peat substrate with good water retention, high permeability, and reasonable nutrient content. Add 50% wettable powder of multisporin (1‰–2‰) or 70% methylthiosulfonate (100 g/kg) to 1,000 kg of substrate, mix well, and ensur
