钻天柳育苗及栽培技术的研究

Study on Seedling Silviculture and Planting Measure of Chosenia arbutifolia (Pall.) A. Skv.

通过对钻天柳种子物候观测和花期、果期观测以及对不同时间采集的种子进行发芽试验 ,掌握了该树种种子成熟时间、成熟标准及采种时间。通过不同播种方法对比试验 ,选出了最佳的播种方法 ,解决了钻天柳种子繁殖育苗的关键性技术问题。又通过不同立地类型造林对比试验 ,选择出适宜钻天柳生长的最佳立地类型 。

Seed mature time, mature standard and collecting time were determined on basis of the observation on phonology of seeds, flower period and fruit period of Chosenia arbutifolia (Pall.) A. Skv. and sprouting experiment of seeds that collected in different time. The optimum sowing measure was selected and the key point of seedling culture was solved by contrast experiment on different sewing measures. The optimum site types which suited to the species grow were determined by means of contrast experiment. These results laid a scientific foundation for this valuable tree species culture.
