Introduction
Analysis of the core content of the standard
GB/T41365-2022 established for the first time a complete quality evaluation system for Atractylodes macrocephala seedlings, dividing the seedlings into three levels:
| Grade index | Level 1 | Level 2 | Level 3 |
|---|---|---|---|
| Single root weight (g) | >30 | 15-30 | <15 |
| Number of fibrous roots (roots/tree) | >20 | 10-20 | <10 |
| Number of terminal buds/lateral buds (per tree) | >3 | 2-3 | 1 |
Key points of technical innovation
The standard innovatively adopts the three-dimensional grading method:
- Morphological indicators: specify the appearance characteristics of leg shape/frog shape and yellow color requirements
- Biomass indicators: objectively reflect the nutritional reserves of seedlings through the weight of a single root
- Activity indicators: measure the reproductive potential by the number of fibrous roots and buds
Implementation Guide
Inspection of key control points
- Sampling specification: 500,000 plants are the maximum batch, and 300 plants are the minimum sample size
- Weight detection: the accuracy of the electronic balance must reach 0.01g, and the error of ±5% is allowed
- Bud point determination: only obvious protrusions visible to the naked eye are counted in the quantity statistics
Storage and transportation practice suggestions
Long-term storage must meet the following requirements: temperature ≤ 25℃, relative humidity ≤ 65%, and moisture-proof mud floor. It is recommended to turn over and check every 72 hours
Standard evolution analysis
Compared with traditional experience judgment, this standard has achieved three major breakthroughs:
- First quantification of Atractylodes macrocephala seedlings grading parameters
- Introduction of statistical significance requirements (3 repeated tests)
- Establish a traceable labeling system (including 12 elements such as harvest period and storage period)
