Abstract

The invention discloses a stable rooting method for poplar cuttage, and belongs to the technical field of tree seed propagation. The stable rooting method for the polar cuttage comprises the following steps of wrapping the top end of an explant with leaves with a water absorbing material, girdling a base part, soaking in water for culture, dropwise adding auxin on the water absorbing material during culture to obtain an explant with adventitious roots, and then performing cuttage. According to the stable rooting method for cuttage, the use concentration of exogenous auxin is effectively reduced, the bacterium breeding phenomenon caused by a traditional culture method is avoided, the purposes of enabling poplar cuttage branches to stably root and improving the transplanting survival rate are achieved, and a new working method is provided for asexual propagation of the poplar and rapid rooting of the cuttage branches.

Description

technical field

[0001] The invention relates to the technical field of tree species propagation, in particular to a method for stable rooting of poplar cuttings. Background technique

[0002] Poplar has strong adaptability to the environment and is widely distributed. It can grow well no matter it is fertile land or barren mountainous area. Poplar has high economic use value and environmental protection value. Its trunk is straight, its material is fine and dense, and it grows fast. It is one of the important tree species in pulpwood raw material forest, and it is also one of the afforestation tree species in excellent water conservation forest and main shelter belt.

[0003] At present, poplar is mainly propagated by cutting seedlings, but the survival rate of conventional cuttings is low and there is a problem that it is easy to die after cutting. Ensure that enough adventitious roots grow before cutting, and it is easy to cause waste of cuttings and increase the cost. A...
