What data looks like for this category
Financial marketing and operational documents for crop farming mainly come from agricultural input procurement installment plans for growers, agricultural insurance product descriptions, financial service guides supporting agricultural technology promotion, and supporting content such as field observation record ledgers and agricultural product market weekly reports. Update rhythms vary by document type: financial product descriptions are updated iteratively, with a cycle of approximately one quarter; field records and market weekly reports are updated weekly or in real time; annual planting plan documents are updated annually.
Document structures include plain text technical paragraphs, Excel planting ledgers with merged cells, multi-sheet crop classification tables, and structured content with fields such as growth stage, application dosage, and yield per mu. Common units include kilograms, mu, milliliters, yuan per kilogram, and similar units.
What constraints these characteristics impose on the "document parsing and chunking" link
As a carrier of financial industry marketing content for the crop farming industry, the multi-table and multi-sheet structure of such documents causes conventional parsing tools to fail to accurately identify classification information in merged cells, leading to field misalignment or loss.
Long-text planting technical guides are divided into chapters by growth stage. If chunks are arbitrarily truncated, the complete logical association of crop growth cycles will be disrupted, reducing the accuracy of subsequent content retrieval. Some documents use mixed non-standard units, such as some records using jin for yield labeling and others using kilograms. Parsing must retain original units for subsequent unified processing.
High-frequency updated field record documents have large single-parsing data volume, increasing timeout risks, so parsing parameters need targeted adjustments.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Crop farming documents often contain multi-sheet tables and long-text technical paragraphs, with higher parsing time than general categories |
UPLOAD_FILE_MAX_SIZE | 1000 MB | A single annual planting plan document may integrate multiple batches of field records and market data, so upload limits need to be relaxed |
Chunk Length | 800–1200 characters | Paragraph length of growth stage chapters in planting technical guides falls within this range, and splitting here preserves complete planting logic |
PARSE_EXCEL_MERGE_CELL | Enabled | Crop farming Excel ledgers often use merged cells to label crop categories and cycle divisions, so cell association information must be retained |
PARSE_EXCEL_SHEET_MODE | Use sheet name as chunk prefix | Multi-sheet documents store different crop classifications separately; adding a prefix avoids content confusion after chunking |
The parameter values provided on this page are general recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: After uploading an Excel planting ledger, the yield per mu field for some crops is empty. Cause: The
PARSE_EXCEL_MERGE_CELLconfiguration is not enabled, so crop classification information in merged cells is not correctly parsed, leading to lost field association for subsequent rows. - Phenomenon: After uploading a large annual planting report, parsing fails after 2 minutes, and restarting the server does not resolve the issue. Cause: The
PARSE_FILE_TIMEOUT_SECONDSconfiguration value is set too low, not matching the parsing time required for multi-sheet documents. - Phenomenon: After parsing a multi-crop Excel document, chunked content does not distinguish crop types, and mixed data from different categories is retrieved. Cause:
PARSE_EXCEL_SHEET_MODEis not configured to use sheet name as chunk prefix, so no classification identifier is added to chunks.
How to confirm configurations are correct
- Upload an Excel planting ledger with merged cells, check if parsed fields fully retain classification information.
- Upload a multi-sheet document of conventional document size, verify that no timeout error is triggered during parsing.
- Review chunked document fragments, confirm that the start of each fragment carries the crop classification name of the corresponding sheet.
- Test uploading a PDF format planting technical manual, confirm that parsed paragraphs are not arbitrarily truncated, and the complete growth stage logic is preserved.
