不同立地条件下伯乐树早期生长试验
|
摘要
[目的]研究不同立地环境对伯乐树早期生长的影响。[方法]监测不同立地条件下伯乐树树苗的生长情况。[结果]坡位、郁闭度和海拔明显影响伯乐树地径增长;水源对伯乐树株高的增长有显著影响;模拟水源和模拟坡位对伯乐树的发芽个数有显著影响;模拟水源和对照组条件对伯乐叶片数量有显著影响;枝数量在3、4月份出现较低值,然后呈现增长趋势,逐月递增到7月达到较高值,后出现下降趋势;发芽个数在2、3月份出现较低值,为1.21,然后从5月呈现增长趋势,至9月出现较高值为1. 71,后呈现递减趋势。[结论]基本掌握了伯乐树不同立地环境的种植技术。
[Objective] To study the effects of different site environments on early growth of Bretschneidera sinensis. [Method] The growth of Bretschneidera sinensis seedlings under different site conditions was measured. [Result] Slope position, canopy density and altitude significantly affected the diameter of Bretschneidera sinensis; water source significantly affected the height of Bretschneidera sinensis;simulated water source and simulated slope position significantly affected the germination number of Bretschneidera sinensis;simulated water source and control group conditions significantly affected the leaves number of Bretschneidera sinensis;branch number showed a low value in April, and then showed a growth pattern, which increased reached a high value in July; the germination number was 1.21 in March,then increased from May to September, with a higher value of 1.71, and then decreased. [Conclusion] The planting techniques in different site environments of Bretschneidera sinensis were basically mastered.
