林木扦插生根率影响因子研究进展

扦插育苗技术可在较短时间内生产大量优质苗木,但不同树种的扦插生根率不同,对其种植推广产生不同程度的影响.文章对林木树种扦插生根研究中,插条质量、来源、采集季节、扦插基质以及生根剂等各种因子对扦插生根率的影响进行综述,分析了影响扦插生根率的具体原因,并指出了今后应加强的研究方向.

The Rooting Rate Factors of Tree Cutting

Cutting technique can produce a large number of high-quality seedlings in a short time. However, different species have different cutting rooting rates, which have different influences on the planting promotion. In this paper,the cuttings quality, origin, collecting season, cutting medium and rooting agent which had effect on the cutting rooting rate were summarized. In addition, the specific reasons that affect the rooting rate were studied. It pointed out the direction of research which should be strengthened for the future development of various plant cuttings to achieve higher rooting rate and provided an important reference to promote the development of clonal forestry.
