Basic Information
Scope
The core planting technology system includes: 1. Precise control of the production environment Based on factors such as altitude gradient, soil, and climate, it reflects the altitude gradient, temperature, rainfall, and soil requirements of the core production areas. 2. Variety and seed treatment Variety selection: Mainly promoting "Xianyi 1" (Fujian Approved Hybrid 2013001), with a planting density of 1.5-4 kg per mu. Seed treatment: Thermal disinfection: Soak the seeds in 60°C warm water for 30 minutes to kill the black smut fungal spores; Lime coating: Mix the seeds with lime powder to prevent underground pests and improve seedling emergence rate; Critical moisture content control: Store the seeds with a moisture content of ≤13% (to prevent mold growth). 3. Standardized planting techniques Establish planting time, water and fertilizer management plans, and green prevention and control methods to achieve standardized planting techniques. 4. Harvesting and drying Harvesting timing: When 70-80% of the fruit spikes are mature; Drying process: Turn and dry the harvested seeds for 7-8 days until the moisture content reaches ≤12% (air-dry to promote starch conversion, increase viscosity, and improve storage quality).
