Scope

Main Technical Content: 3. Planting Environment in the He Tu Irrigation Area 3.1 Requirements for Soil Conditions in Greenhouses - Select a pollution-free area with good production environment for greenhouse construction. Prioritize areas with higher terrain, lower groundwater levels, convenient irrigation and drainage, and deep loam or sandy loam soils that meet the environmental standards for green vegetable production sites. 3.2 Requirements for Greenhouse Insulation Performance - The greenhouse design must adhere to energy-efficient principles, featuring excellent lighting, heating, and insulation performance, convenient ventilation, easy operation, strong resistance to wind and snow pressure, stable structure, and indoor relative illumination of 50%–80%. A cold prevention ditch 30–40 cm wide and 50 cm deep should be set around the greenhouse. The ditch is filled with materials such as wheat straw or 10 cm-thick insulation boards, which can raise the 5 cm ground temperature by 4–5°C. 4. Preparation for Seeding 4.1 Preparation before Seeding - Prepare the seedbed after leveling the soil in the greenhouse. The seedbed is typically 1–1.2 m wide with a 20 cm-high ridge. A 1–2 cm-thick layer of sieved fine soil is spread on the bottom of the seedbed, followed by a layer of plastic film. Heating cables with a spacing of 8–10 cm are laid on the film and connected in parallel. A 2 cm-thick layer of sieved fine soil is then added on top of the heating cables, after which seed trays or nutrient pots can be placed. 4.2 Seed Preparation - Use 50-hole or 32-hole seed trays for seedling cultivation. - Substrate preparation: - Use a mixture of peat and vermiculite (2:1 ratio) with appropriate amounts of composted farmyard manure. - Alternatively, use commercial seedling substrates that meet the requirements of NY/T 2118. - Select nutrient-rich and safe substrates, such as Shandong "Luqing," Ningxia "Zhongqing," or Inner Mongolia "Mongda" fu
