Tradescantia cutting propagation method

Abstract

The invention discloses a tradescantia cutting propagation method. The method comprises the steps of selecting a stock plant, preparing a propagation material, manufacturing a cutting shoot, maintenance and the like. By adopting the method, a 'single bud or single node' stem is used as a cutting shoot, so that the cutting shoot yield is improved by three times, and the propagation coefficient is improved by three times than that of an existing method. The method has the advantages of high propagation rate, simple operation, cost saving, easily available materials, high survival rate, no influence for existing landscape and the like, is especially suitable for large-scale planting and industrial production, and has an important meaning for achieving the potential advantages of tradescantia in landscape construction and the like.

Description

technical field [0001] The invention relates to a rapid propagation method of spiderwort, in particular to a cutting propagation method of spiderweed, and belongs to the technical field of plant propagation. Background technique [0002] Spiderwort (Tradescantia ohiensis Raf.) is a perennial herb of the genus Spiderwort in the Commelinaceae family. The stem is 30-50cm long, with more than 3 nodes on the stem, and the nodes are slightly enlarged; the single leaves are alternate, broadly linear, and the petioles are clasping; the petals are blue-purple, broadly ovate; flowering from May to November in Xi'an area, but June-July is the peak season. Capsule ellipsoid. [0003] Native to the tropical regions of America, there are more than a dozen horticultural varieties introduced and cultivated in my country. [0004] Spiderwort has a long flowering period, upright straight, obvious knots, unique and beautiful plant shape, full of wild interest. It is often used to arrange f...

AI Technical Summary

Problems solved by technology

[0006] (1) The maturity of the seeds is extremely low, and it is difficult to obtain seeds with germination ability in the natural state; the flowering duration is long, generally between May and November, and the seeds fall with maturity, so it is difficult to collect them collectively; even if there are individual seeds Able to germinate, the offspring vary greatly, and it is difficult to retain the original excellent traits

[0007] (2) Propagation by ramets will be limited by the number of mother plants

[0008] (3) When conventional methods are used for cutting propagation, the utilization rate of cuttings is low

[0009] Due to the limitations of the above factors, the reproductive rate of spiderwort is low, and it is difficult to carry out large-scale production, which seriously hinders its application and industrialization in flower borders.
