Cutting propagation method for euonymus carnosus

Abstract

The invention provides a cutting propagation method for euonymus carnosus and belongs to the technical field of plant propagation. The method includes the following steps that 1, a proper propagation field is selected for building a euonymus carnosus female parent cutting orchard; 2, a matrix is put in a 72-hole tray; 3, the proper cutting time is the first ten days or the middle ten days of September, and cutting is carried out once a year; 4, cutting branches are soaked with a root promoting agent; 5, 40 days after cutting, about 70% of scions root, and then seedling hardening can be started. The cutting propagation method for euonymus carnosus is easy to operate and high in propagation speed, the problem that the survival rate of cutting propagation of euonymus carnosus is low is solved, the yield reaches up to 90%, and the method can be used for large-scale production.

Problems solved by technology

Euonymus japonicus belongs to the type that is difficult to root from cuttings. The existing literature reports that its seedlings are mostly propagated by sowing, but the seeds of Euonymus japonicus are dormant when they mature, so they cannot be directly sown, and their germination rate is low, so they are not suitable for large-scale propagation.

Liu Feiyan et al. (1995) conducted preliminary research on the tissue culture of Euonymus sarcophagus, but there was no large-scale application and the cost was high

Chen Liqing et al. (2004) used cuttings to propagate Euonymus succulents for the first time, and found that the survival rate of cuttings was lower than 8.6%.

The low survival rate of cutting propagation of Euonymus sativa is the bottleneck restricting its large-scale production
