Scope

Main Technical Content: 1. Seedling Facilities 1.1 Seedling Sites: - Depending on the season and climate conditions, select seedling facilities such as solar greenhouses, plastic greenhouses, and multi-span greenhouses. During summer and autumn, insect-proof and shading facilities should also be provided. In winter and autumn, insulation facilities such as quilts and straw curtains are required. All seedling sites and facilities should be disinfected. 1.2 Mobile Seedbed Greenhouses: - Install mobile seedbeds in greenhouses. The seedbeds should be placed north-south, with a height of 75.00cm-80.00cm, a width of 160.00cm-180.00cm, and an unlimited length. A 45.00cm-50.00cm-wide walkway should be left between the seedbeds. 1.3 Sprinkler Systems: - Install walk-behind or fixed automatic sprinkler systems in multi-span greenhouses. In solar and plastic greenhouses, use long hoses with fine-hole spray heads for manual watering. 1.4 Germination Chambers: - In winter, build germination chambers in greenhouses. The chambers should be equipped with seedling tray racks, with a height of 2.00m, a length of 2.20m, and a width of 0.60m. Three to four layers of partitions should be installed, with the bottom layer 20.00cm above the ground and a spacing of 40.00cm-60.00cm between layers. 1.5 Cell Tray Specifications: - Select 50-hole, 72-hole, or nutrient trays. Disinfect and sterilize the trays with a 1000-fold potassium permanganate solution before use. 2. Substrate 2.1 Substrate Selection: - Select substrate materials such as peat soil, vermiculite, and slag. Alternatively, purchase commercial substrates from manufacturers. 2.2 Substrate Quality: - Self-prepared substrates should meet the following requirements: porosity 60%, pH 6-7, soluble nitrogen ≥ 150.00mg/kg, effective phosphorus ≥ 50.00mg/kg, and available potassium ≥ 100.00mg/kg. 2.3 Commercial Substrate Quality: - Effective microorganisms (≥ 5.00x10^6 CFU/g) a
