Scope

Main technical content: 6. Rice production technology 6.1 Sowing 6.1.1 Seed treatment - Soak the seeds in 1% lime water for 30 hours before sowing. After washing the seeds with clean water, germinate them until the seeds crack and the roots become white. - Sow the seeds in early to mid-March and spread them evenly on the prepared seedbeds. - Sowing quantity: - Conventional rice: 2.5 kg per 667 m2 - Hybrid rice: 1.5 kg per 667 m2 - For tray-grown seedlings, typically sow 60 g of hybrid seeds and 100 g of conventional seeds per tray. - Transplanting age: Generally around 30 days, with a maximum of 35 days. -6.1 Seedling field management 6.1.3.1 Water and fertilizer management - Keep the field surface moist. Before the seedlings reach two leaves, irrigate during the day and expose them to the sun at night. On clear days, irrigate with shallow water in the furrows to maintain soil moisture; on rainy days, irrigate with half-furrow water. - After the seedlings reach two leaves, drain the water and irrigate with shallow water. Starting from when the seedlings grow three leaves, if the seedlings show yellowing due to nutrient deficiency, apply 10 kg of bio-organic fertilizer leachate per 667 m2 every 5 days. - Cover the seedlings with plastic film immediately after sowing to prevent seedling rot. -6.1.3.2 Weeding the seedbeds - Remove weeds from the seedbeds before transplanting. -6.2 Transplanting - Transplanting requirements: - In mid-to-late April, transplant the seedlings promptly when they reach 3.5–4 leaves to prevent them from aging. - Ensure sufficient seedling density: - Conventional rice: 18,000–20,000 holes per 667 m2, with a basic seedling number of 55,000–60,000 - Hybrid rice: 16,000–18,000 holes per 667 m2, with a basic seedling number of 30,000 - For machine-transplanted seedlings, increase the basic seedling number appropriately. - Transplanting is best done on overcast days or in the eve
