本文对柚木(Toctona grandis)在海南岛西南部地区的播种、分床、苗木生长规律与苗木管理等育苗措施进行了试验观察研究,为1年生苗木生长过程配置理论方程,并对影响苗木生长的气象因子、苗木分级指标进行了分析。结果表明:以1月份播种能最有效地利用苗木生长季节:当芽苗第一对真叶达到正常大小时分床最合适;气温为影响苗木生长:的主导因子;地径为苗木的分级指标。
In this paper, the seedlings of Toctona grandis in the southwestern part of Hainan Island were sowed, divided, the growth rules of seedlings and nursery stock management were studied. The theoretical equations were provided for the growth of 1-year-old seedlings, Meteorological factors, seedling grading index were analyzed. The results showed that sowing in January could make the most effective use of seedling growth season when the first true leaf of shoots reached the normal size and the most suitable bed was bed temperature. Temperature was the dominant factor affecting seedling growth. .
