적용 범위

This standard serves as the official basis for inspecting and grading ginseng seedlings (*Panax ginseng*). It is specifically applicable to ginseng production, scientific research, and commercial trade, focusing on the classification and quality assessment of 1 to 3-year-old seedlings. It is strictly utilized for evaluating seedling quality prior to transplantation.

기술 요구 사항

The standard establishes precise grading criteria based on single root weight, root length, and overall physical integrity. Seedlings are categorized into different grades (ranging from 2 to 4 tiers) depending on their age (1 to 3 years), with specific minimum weight and length thresholds defined for each category. All qualified seedlings must possess intact root systems, uniform winter buds, and sufficient plumpness without obvious signs of disease or mechanical damage. Furthermore, the standard outlines comprehensive agronomic practices for nursery management. This includes selecting premium seeds for breeding, mandating strict seed disinfection protocols using chemical agents like polyoxin or formalin, and specifying soil requirements such as high organic matter content. Cultivators must adhere to defined planting densities and seedbed dimensions to ensure optimal growth conditions. Post-harvest handling is also strictly regulated. The standard requires careful excavation to prevent root breakage and mechanical injuries. Seedlings must be accurately sorted according to their designated grades and packaged separately with clear labeling to prevent cross-grade mixing during transportation to the planting site.

시험 방법

Quality verification involves random sampling to evaluate standard rate, single root weight, and physical condition. Inspectors measure root length using a ruler and calculate the percentage of conforming seedlings, requiring a standard rate of over 95% for approval. Additionally, the testing assesses the uniformity of winter buds, the average weight per plant, and the level of root plumpness (*浆气*), where samples containing more than 5% of under-plumped roots are rejected. Visual inspections are conducted to ensure roots are free from disease spots and mechanical scars.

자주 묻는 질문

What products are regulated under GB 6942-1986?

The standard applies to ginseng seedlings specifically aged 1 to 3 years. It is used for quality inspection, grading, and trade within ginseng production, scientific research, and commercial operations.

How are ginseng seedlings classified under this standard?

Seedlings are classified into grades based on single root weight, root length, root shape, and the degree of disease or damage. 1-year-old seedlings have 2 grades, 2-year-old have 3 grades, and 3-year-old have 4 grades, with any non-conforming seedlings classified as substandard.

What are the key technical requirements for seedling cultivation?

The standard mandates the use of premium seeds, strict seed disinfection (e.g., using polyoxin or formalin), specific soil and seedbed preparation, precise planting spacing based on seedling age, and careful harvesting to prevent mechanical damage.
