Scope
Scope: This standard specifies the terminology and definitions for the production of black-seeded pumpkin seeds, as well as seed production techniques. This standard applies to the conventional seed production of black-seeded pumpkins in the arid-hot valley of Jinsha River, Yunnan Province. Main Technical Content: 1. Seedling Stage 1.1 Prepare the substrate mixture according to the ratio of Pinson peat moss: pearlite = 12:1. 1.2 Place the substrate mixture into 72-hole trays and level it with a wooden board tilted at a 45-degree angle to the front. 1.3 Break dormancy by soaking the seeds in a 2.5-5% hydrogen peroxide solution for 12 hours. 1.4 Germinate the seeds by soaking them for 5-6 hours at a strictly controlled temperature of 30-32°C (24 hours until the seeds sprout and the radicle becomes visible). 1.5 After completing seedling planting, water the trays until the bottom does not drip. Poke holes in the center of each tray at a depth of 1.5cm. Plant one seed per hole and cover with a mixture of Pinson peat moss and pearlite (60kg Pinson peat moss + 9kg pearlite). 1.6 Seedling Management: The seedlings typically grow for 10-12 days. During this period, focus on water management and pest/disease prevention. Keep the substrate in the trays moist but not overly dry before transplanting. Spray pesticides once before seedling transplantation. 2. Transplanting 2.1 Site Selection: Require fertile soil with convenient irrigation and drainage, as well as fields free from melon crops for three years. 2.2 Land Preparation: Create 350cm-wide furrows with 300cm-wide beds and 50cm-wide trenches 30cm deep. Apply base fertilizer via nutrient trenches (40kg compound fertilizer, 40kg dolomite lime, and 1,500kg farmyard manure per mu). 2.3 Planting Specifications: Double-row planting with 50cm spacing between rows. Plant 760 seeds per mu. 2.4 Covering with Film: Cover the seedlings immediately after transplanting and puncture the film with holes 10cm
