| 摘 要： | 对在北京播种的红花玉兰1 a生实生苗的生长规律及苗木质量进行调查,比较红花玉兰和白玉兰在形态及生理指标上的生长差别,并对观测和试验结果进行分析。结果表明:红花玉兰苗高、地径的生长规律符合苗木的S型生长曲线,可用Logistic曲线拟合,因此将幼苗的生长划分为4个时期,分别为出苗期3月22日到5月21日、生长初期5月22日到6月29日、生长旺期6月30日到9月1日、生长后期9月2日以后4个时期。同等栽培条件下,红花玉兰形态方面的生长情况明显优于白玉兰;生理方面,红花玉兰在纤维素含量及根系活力方面明显高于白玉兰,且差异显著。

| Abstract: | Researching on the quality and the growth laws of Magnolia wufengensis' one-year old seedling,which were sowed in Beijing.And compared the growth different between Magnolia wufengensis and Magnolia in the morphological and physiological indicators.The results indicated that Magnolia wufengensis' growth patterns of height and caliper were fitted for S curves and can be simulated with Logistic equation.At the same time,the growing period was divided into 4 stages according to its growth rate,which were the em... |
