Short-scion cutting propagation method for star anise

Abstract

The invention discloses a short-scion cutting propagation method for star anise. The short-scion cutting propagation method comprises the processes of seed tree management and culture, collection and processing of scions for cutting, cutting and management after cutting. The method comprises managing and culturing 11-year to 14-year excellent clonal grafting dwarf star anise seed trees artificially cultured in a nursery, collecting and pruning scions of 4cm to 6cm, performing cutting of the scions in a cutting bed with a cutting medium, and obtaining star anise cutting seedlings by controlling illumination in the cutting bed, relative humidity and water content of the medium. The scions obtained by the propagation method are excellent and pure in quality, take root easily, are low in cost and simple to operate, propagate rapidly, are high in propagation coefficient, and maintain characteristics of excellent clonal star anise varieties. The cutting seedlings are resistant to drought, waterlogging, wind and pest and disease damage and high in low-temperature resistance and fruit early, a tree crown is dwarf, fruit harvest is facilitated, and the cutting seedlings has good economic benefit and social benefit.
