Embodiment 1

[0021] Embodiment 1 The blade mist cutting propagation of Echeveria "Chihuahua" variety

[0022] (1) Cultivate the female parent

[0023] On June 28, the "Chihuahua" Echeveria seedlings were transplanted into flower pots filled with the female parent's cultivation medium. The size of the flower pots: diameter×height=120mm×110mm, placed in a colorless transparent plastic greenhouse. For light cultivation, conventional measures are adopted to control the temperature in the greenhouse during the day to 20-24°C, the night temperature to 10-12°C, and the relative air humidity to 55%-65%. Cool down; when the temperature drops, close the top skylight and side film or add a cover film. When white appears on the surface of the female parent cultivation substrate of the flowerpot, watering is started, and the amount of watering is only when water overflows from the bottom of the flowerpot. The compound fertilizer of fertilizing 1 time 2000 times of liquid every two weeks, N content is...

Embodiment 2

[0033] Example 2 Cutting Propagation of Echlossia "Yin Frost" Variety Leaf Misty Fog

[0034] Embodiment 2 is the same as Embodiment 1 except that the following steps are different, and will not be repeated here.

[0035] (1) Cultivate the female parent

[0036] The female parent is the "Yin Shuang" variety of the genus Echeveria, and the seedlings of "Yin Shuang" were transplanted on July 11. The daytime temperature in the plastic greenhouse is 25-27°C, and the night temperature is 13-14°C.

[0037] (2) Leaf stripping and wound healing

[0038] The leaves were removed on September 26. Plastic baskets were placed in a greenhouse with a shading rate of 80%.

[0039](3) Preparation of cutting bed

[0040] A sunshade net with a shading rate of 80% is installed on the top surface of the mist plastic shed. The mixed fungicide is prepared by mixing equal volumes of 80% mancozeb wettable powder 1000 times liquid and 72% agricultural streptomycin soluble powder 1000 times liquid...

Embodiment 3

[0046] Embodiment 3 Leaf Misty Cutting Propagation of Echinacea "Black Prince" Variety

[0047] Embodiment 3 is the same as Embodiment 1 except that the following steps are different, and will not be repeated here.

[0048] (1) Cultivate the female parent

[0049] The female parent is the "Black Prince" variety, and the seedlings of "Black Prince" were transplanted on June 28. The daytime temperature in the plastic greenhouse is 28-30°C, and the night temperature is 15-16°C.

[0050] (2) Leaf stripping and wound healing

[0051] The leaves were removed on September 7.

[0052] (3) Preparation of cutting bed

[0053] The mixed fungicide is prepared by mixing equal volumes of 1500 times liquid of 80% mancozeb wettable powder and 1500 times liquid of 72% agricultural streptomycin soluble powder.

[0054] (4) Leaf cutting and management

[0055] On September 11th, place the leaves with the healed wound on the cutting seedbed prepared in step (3) evenly with the back (convex ...

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...
