Mist cuttage and rapid propagation method for Sinocrassula leaves

Abstract

The invention discloses a mist cuttage and rapid propagation method for Sinocrassula leaves. The method comprises cultivation of a female parent, leaf stripping, wound healing, preparation of a cuttage bed, leaf cuttage and management, and plug seedling management. In the cultivation of the female parent, a soilless cultivation way is adopted; the temperature is kept at 20-30 DEG C in the daytime and at 10-16 DEG C at night; the relative air humidity is 55-65 percent; and a compound fertilizer is applied once every two weeks. Cuttage leaves are placed into a greenhouse of which the shading coefficient is 80-85 percent for airing till base wounds of the leaves are healed. Cinerite is taken as a seedbed cuttage substrate. The temperature in a leaf cuttage shed is kept at 20-30 DEG C in the daytime and at 12-16 DEG C at night, and the relative air humidity is kept at 80-90 percent. The leaves are transplanted after rooting, and turf and cinerite are taken as substrates. The temperature and humidity in a plug seedling shed are the same as those in the female parent cultivation. Through adoption of the method, a cultivated female parent is robust; cuttage leaves take root quickly; from cuttage to rooting and seedling emergence, 35-42 days are spent; from cuttage to the formation of commercial seedlings, 45-57 days are spent; and the cuttage seedling rate is over 96 percent. The method is suitable for large-scale seedling production.

Description

technical field [0001] The invention relates to a method for rapidly propagating leaves of plants by cuttings, in particular to a method for rapidly propagating leaves by cuttings of the genus Echlossia sedum, and belongs to the technical field of plant propagation. Background technique [0002] Sinocrassula, mainly distributed in northern Pakistan to southwest China, central to northwest. Biennial or perennial herb, with rosette-like leaf clusters, thick hairy leaves glabrous or micropapillary; flowers 5 base, arranged in cymes or thin-flowered racemes; calyx basally united, lobes triangular; petals Longer and separated; stamens 5, filaments usually conjoined; in recent years, succulents of the genus Echeveria have been favored more and more because of their drought tolerance, barren tolerance, and easy maintenance. [0003] The propagation methods of Echeveria mainly include seed propagation, branch propagation, cutting propagation and tissue culture propagation. Among t...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the high rot rate of cutting leaves in the cutting propagation of the prior art, slow rooting, the success rate of cuttings largely depends on the experience of the cutting person, the reproductive efficiency is unstable, and there is no systematic and complete comprehensive cutting rapid propagation cultivation measures , it is difficult to adapt to the problem of large-scale production
