Problems solved by technology

[0003] At present, the research on Lilium Nanchuan focuses on the investigation of wild resources and in vitro rapid propagation technology, and the research on the seed propagation of Lily Nanchuan is rarely reported
And based on the following reasons, the existing propagation methods of Lilium Nanchuan are not enough to guide production: ① When the scales, leaves and stems of Lily Nanchuan are used as explants for rapid propagation, the pollution rate is high and the healing rate is low ; ② When the ovary and receptacle were used as explants, the meristem ability was strong, the induction differentiation rate was high, and the number of buds was large, but the reproductive organs of wild resources were destroyed; ③ The scales of adventitious bud leaves and regenerated bulblets were used as explants. Tissue culture is a feasible way, but due to the large number of endophytes in Lily Nanchuan, the whole process is laborious and laborious, which is not conducive to large-scale production; ④The source of Lily Nanchuan is scarce, and fresh scales are used as the source of cuttings for propagation. Low, not conducive to scale expansion, and a large demand for wild resources
[0004] Therefore develop a kind of propagation method that adopts seed as raw material to produce Nanchuan lily seedling, solve the problem of wild resource consumption in large quantities in the Nanchuan lily propagation method

Embodiment 1

[0052] Example 1 fermented and decomposed money herb dregs

[0053] Preparation steps:

[0054] ①Preparation: cool the dried herb dregs extracted by water for 2-3 days until the water content is about 75%, and obtain the dregs to be fermented;

[0055] ②Pile fermentation:

[0056] Add 0.1% of its quality urea, 0.3% of lime and 0.1% of fermentation bacteria to the dregs to be fermented in step ①, fully mix, and build a rectangular pile with a height of 1.1-1.3 meters for heat preservation and ventilation effect Better, cover the white film after building the heap, and ferment;

[0057]The fermentation agent is activated with a wheat bran brown sugar medium;

[0058] ③Completion: When the fermentation time is about 30 days, the traditional Chinese medicine dregs are completely decomposed and have no peculiar smell, which is the fermented and decomposed money herb dregs.

Embodiment 2

[0059] The propagation method 1 of embodiment 2 Nanchuan lily

[0060] (1) Seed collection period and treatment

[0061] a. In December, the seed coat of Lily Nanchuan turned yellow, and the seeds began to be collected when the top cracked;

[0062] b. After the seeds are harvested, use a nylon mesh bag to air-dry indoors for later use;

[0063] (2) Sowing time and cultivation substrate treatment

[0064] a. Sowing time: sowing on March 6;

[0065] b. Cultivation substrate treatment: crush and sieve the fermented and decomposed money herb dregs, mix them with vermiculite at a volume ratio of 3:1, adjust the water content to about 60%, use 1500 times of Dixad and Hymexazol 3000 times of liquid is used to disinfect the seedling substrate, which can be used on the same day;

[0066] c. Untreated seeds

[0067] d. Sowing: Spread the seedling cultivation substrate on the floating tray (165 holes) to 2 / 3, press slightly, put 2-3 seeds in each hole, cover the cultivation substra...

Embodiment 3

[0073] The propagation method 2 of embodiment 3 Nanchuan lily

[0074] (1) Seed collection period and treatment

[0075] a. In January, the seed coat of Lily Nanchuan turned yellow, and the seeds began to be collected when the top cracked;

[0076] b. After the seeds are harvested, use a nylon mesh bag to dry indoors for later use;

[0077] (2) Sowing time and cultivation substrate treatment

[0078] a. Sowing time: Sowing can be carried out when the ground temperature is above 15°C;

[0079] b. Cultivation substrate treatment: use the fermented money herb residue and vermiculite to mix according to the volume ratio of 3:1, control the water content of the substrate to 60%, use 1500 times of dimethazol and 3000 times of hymexazol to Seedling culture substrate is sterilized, and it is standby after 10 days;

[0080] c. Seed dressing treatment: use high calcium (imidacloprid) to dress the lily seeds, and the seed dressing concentration is 3 kg of lily seeds and 10 g of imida...

Abstract

The invention belongs to the field of plant protection and breeding, and particularly relates to a propagation method for lilium rosthornii Diels. The method comprises the steps of seed collection, seed treatment, medium composition and matched cultivation management. According to the propagation method, seeds are adopted as raw materials to produce seedlings of lilium rosthornii Diels, and the problem that a lot of wild resources are consumed in a propagation method of lilium rosthornii Diels is solved; the yield of seeds of lilium rosthornii Diels is large, in cooperation with suitable harvesting and seed treatment, fermented and decomposed medicine residues of christina loosestrife herbs and vermiculite serve as a seedling raising medium, the hydrophilic characteristic of lilium rosthornii Diels is utilized, a floating seedling raising method is adopted, the seedling emergence rate of lilies is greatly increased, and a large number of lily bulbs can be obtained within a short time.By successfully using the propagation method, the wild resources of lilium rosthornii Diels can be effectively protected.

Description

technical field [0001] The invention belongs to the field of plant protection and breeding, in particular to a method for breeding Nanchuan lily. Background technique [0002] Nanchuan lily (Lilium rosthornii Diels) is a unique wild lily species in my country. It has high medicinal value and ornamental value. It is also an important breeding material in horticulture and has high research and utilization value. Due to the high environmental requirements of lily Nanchuan and the destruction of lily Nanchuan due to human activities, its survival status is in jeopardy. [0003] At present, the research on Lilium Nanchuan focuses on the investigation of wild resources and the in vitro rapid propagation technology, and the research on the seed propagation of Lily Nanchuan is rarely reported. And based on the following reasons, the existing propagation methods of Lilium Nanchuan are not enough to guide production: ① When the scales, leaves and stems of Lily Nanchuan are used as ex...
