辐射松(Pinus radiata)苗木质量的评定,以其造林后生长的能力作为评定优劣的标准。对此而言,就苗圃技术措施与苗木出圃时的大小或易于测得的其他任何参数相比较来说,应以苗圃的技术措施为主要的参考依据。这里需要稍加强调的是,这个结论最适应于栽植在良好的和庇阴的生长条件下的苗木。最有实用价值的测定苗木质量指标是茎与高之比和地径的大小。对任一树种和任一龄级的苗木来说,最佳茎高比与苗圃的立地
Pinus radiata seedling quality assessment, with its ability to grow after afforestation as a measure of merits. In this regard, nursery technical measures and seedlings nursery when the size or other parameters can be easily measured compared to the nursery should take the technical measures as the main reference. What needs to be emphasized here is that this conclusion is best adapted to nursery stock planted in good and overcast conditions. The most practical value of seedling quality indicators is the ratio of stem to height and diameter size. For any tree species and any age class of seedlings, the best stem height ratio and nursery site
