| 摘 要： | 为了探讨2年生红椿苗最佳的育苗密度,开展了红椿育苗密度试验研究,结果表明:随着育苗密度增加,苗木的苗高和地径均减小,苗木的质量下降。因此,确定合理的育苗密度是培育优质红椿苗并取得最佳育苗效益的关键。研究表明:二年生的红椿苗木如只生产Ⅰ级苗,则合适的育苗密度为30株/m2;如Ⅰ、Ⅱ级苗均用于生产造林,则合适的育苗密度为40株/m2。 |

| Abstract: | ln order to discuss the optimum seedling density of Toona ciliate, different seedling densities were studied. The results showed that seeding height and basal diameter decreased and quality of the seedlings declined with the increase of seedling density. The reasonable density of seedlings is key to cultivate high-quality seedlings and achieve the best seedling efficiency. The optimum density was 30 plants/m2 for the first class seedlings of biennial seedlings, and the optimum density of l and ll seedlings for production afforestation was 40 plants/m2. |
