|---|---|---|---|
| Structural system | 9 chapters | Integrated into 7 chapters | Merge chapters on suitable sowing areas and sowing area selection |
| Seed treatment | Not separately stipulated | New section 6.4 | Specifies 12 treatment methods such as disinfection/coating/pelletization |
| Investment budget | 4 types of expenses | 7 types of expenses | Add modern operating elements such as meteorological services/communication equipment |
Key points for the implementation of key technologies
3D model for sowing area selection
Natural conditions: Suitable sowing area ≥ 60%, sunny slope ≤ 40%, terrain height difference meets the 300m limit of Yun-5B aircraft
Social conditions: Land ownership confirmation must be completed, and a 5-7 year closure and protection mechanism must be implemented
Aircraft model selection matrix
| Parameters | Yun-5B | Yun-12 | AS350 |
|---|---|---|---|
| Operation altitude (m) | 80-120 | 80-150 | 80-100 |
| Loading capacity (kg) | 700-800 | 1100-1700 | 300-400 |
| Economic distance (km) | 120 | 200 | 50 |
Special requirements for aerial seeding in sandy areas
Sand barriers should be set up in advance in mobile sandy areas. The priority of material selection is: shrub branches > crop straw > geotechnical materials. The grid specifications are 1m×1m to 2m×2m
Dual indicator system for effectiveness evaluation
Arid and cold areas: Effective seedlings ≥ 1000 plants/hm² and frequency ≥ 20%
Other areas: Effective seedlings ≥ 1666 plants/hm² and frequency ≥ 25%
A 10m² circular plot is used for testing. The sampling density in sandy areas needs to be increased by 20%
