Introduction
Analysis of the core content of the standard
| Data category | Number of elements | Coding rules | Typical parameter examples |
|---|---|---|---|
| Microclimate observation data | 33 items | QX/T133—2011 | Air temperature, CO₂ concentration, photosynthetically active radiation |
| Vegetable growth records | 28 items | NY/T1741—2009 | Development period, planting density, disaster symptoms |
| Facility structural parameters | 28 items | JB/T10288—2013 | Covering transmittance, lighting roof angle |
Key technical requirements
1. Data storage specifications
Adopt the fixed-length storage principle, fill in "0" for insufficient positions, and fill in "/" for default values. For example:
- Air temperature: 5 characters (including decimal point), precision 0.1℃, storage example "023.5"
- Latitude: 8 characters, precision 0.0001°, storage example "039.1234"
2. Information Coding System
Facility type uses a 1-bit code: 1-solar greenhouse, 2-plastic greenhouse, 3-multi-span greenhouse
Pests and diseases use a 6-bit hierarchical code, such as "225800" for leaf mold (fungal disease)
Implementation Suggestions
Notes on Data Collection
- The horizontal azimuth must be recorded when installing the instrument (with the sun-facing direction of the facility span as 0°)
- Ground temperature observations should distinguish between different depths such as 5cm/10cm/15cm
- Disaster records must include the time of occurrence, symptom description and prevention and control measures
System Development Suggestions
| Module | Implementation Points | Related Appendices |
|---|---|---|
| Data Verification | Check Field Length and Coding Compliance | Appendix A Extended Feature Code |
| Metadata Management | Maintain 719 Series Custom Coding | Appendix B Tables B.1-B.7 |
Standard Evolution Analysis
Compared with QX/T261-2015, this specification adds:
- Special parameters for multi-span greenhouses (number of bays, roof slope)
- Facility-specific disaster types (low temperature and low light, code 0211)
- Codes for new management measures such as CO₂ fertilization (0510)
