What This Category’s Data Looks Like
Data for the fertilizers and pesticides category comes from three main sources: agricultural and rural ministry pesticide registration announcements, public standards from the National Technical Committee for Fertilizer and Soil Conditioner Standardization, and filing information submitted by manufacturing enterprises. Each data document covers a single product, and includes these fields: registration certificate number, common name, active ingredient content, applicable crops, application method, pre-harvest interval, and manufacturing enterprise. Most active ingredient content units are grams per liter or mass percentage. Application dosages are measured per mu or per hectare. Data updates occur irregularly when newly registered products are approved or industry standards are revised. Reference only; verify against the target FastGPT release and deployment documentation.
Constraints Imposed by Category Characteristics on Multi-turn Dialogue and Prompt Engineering
This category has many specialized fields and complex unit systems. Multi-turn dialogue prompts must clearly define field extraction rules and unit conversion logic to avoid output confusion. Data updates are irregular. Knowledge bases must be configured with regular synchronization mechanisms. For multi-turn dialogue involving newly approved products, real-time retrieval must be triggered to get the latest information. Applicable scenarios for different products are closely linked. Multi-turn dialogue must retain context association. This ensures subsequent questions can reference previously mentioned products or crops. Single product documents have large information volumes. The length of single retrieved content must be limited to avoid exceeding the context window.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Context window size | 8000–12000 token | Specialized documents for fertilizers and pesticides are lengthy. This range accommodates multi-turn dialogue history and multiple retrieved product information |
messages | Retain the first 10 rounds of dialogue context | Excessive history consumes window capacity. Insufficient history loses product or crop association information from prior questions |
| Question optimization toggle | Enabled | User questions often omit specialized terminology. Optimization improves retrieval matching accuracy |
variables | Preset unit conversion variables | Diverse units exist within the category. Variables can uniformly convert values to commonly used units per mu or percentage |
| Single search limit | Top 6 results | This category has a large number of products. Limiting results avoids context overload |
Three Common Misconfigurations
- Phenomenon: Field formats referenced by the knowledge base do not meet downstream workflow parsing requirements. Missing registration certificate numbers and mixed active ingredient units are common issues. Cause: Standard formats for required fields such as registration certificate numbers and active ingredients are not clearly specified in the prompt. This leads to chaotic output structure of retrieval results.
- Phenomenon: Subsequent questions in multi-turn dialogue cannot associate previously mentioned fertilizer or pesticide products or crop information. The system treats each question as a new query. Cause: The
chatIdparameter is not correctly passed. Each dialogue request becomes independent, and historical conversation context is not retained. - Phenomenon: Streamed output has content truncation or response delays. Some specialized information is not fully returned. Cause: A reasonable response timeout threshold is not configured, or the number of single retrieval results is not limited. Excessive data volume exceeds transmission limits.
How to Verify Proper Configuration
- Initiate a single-turn query. Verify that returned results include preset required fields. Check that field formats match downstream workflow parsing requirements.
- Initiate consecutive multi-turn queries. Verify that subsequent questions can correctly associate previously mentioned fertilizer or pesticide products or crop information. Confirm conversation context is retained by checking the
chatIdparameter. - Test the streamed output function. Observe that responses return content continuously, without obvious truncation or delay. Adjust the timeout threshold to match actual transmission needs.
- Simulate a query for a newly approved product. Verify that the system triggers real-time retrieval and returns the latest registration information. Confirm that the knowledge base synchronization mechanism operates normally.
