对国外的种子植生块造林技术进行了制作时间、包膜处理、小范围整地3项改进,发现现场制作种子块臭椿出苗率和保存率分别比对照提高了13.9%和20.0%,五角枫出苗率和保存率分别比对照提高了22.1%和27.8%。种子块包膜可使臭椿出苗率提高11.08%,保存率提高11.97%;五角枫出苗率提高10.88%,保存率提高11.57%。整地可使臭椿保存率提高5.10%,高生长量提高26.51%;五角枫保存率提高12.52%,高生长量提高23.21%。
The results showed that the emergence rate and preservation rate of Ailanthus altissima were increased by 13.9% and 20.0% respectively compared with the control, and the emergence rate of A. sylvestris And the preservation rate increased by 22.1% and 27.8% respectively over the control. Seed block coating could increase the emergence rate of Ailanthus altissima by 11.08% and the preservation rate by 11.97%. The seedling emergence rate of Aconitum palustris increased by 10.88% and the preservation rate increased by 11.57%. Soil preparation could increase the preservation rate of Ailanthus altissima by 5.10% and increase the growth by 26.51%. The preservation rate of Pentagon maple increased by 12.52% and the growth by 23.21%.
