[0003] At present, the propagation methods of Amaryllis plants are generally seed propagation and natural division propagation, which cannot meet the market demand. The method is researched, and 12-15 seed bulbs can be propagated every year by Lycoris chrysanthemum grown for more than three years, which is 6-10 times of natural bulb propagation. The method of the invention has obtained the national patent right after being declared. The Patent No. ZJ200510003190.3 of the Method for Rapid Asexual Propagation, the inventor of the present invention found in further research that there are still some deficiencies in the Method for Rapid Asexual Reproduction of Hudixiao (referred to as the background method), including (1) the background technology is only for Lycoris The asexual reproduction of a species of Lycoris genus (i.e. Lycoris jinhua) does not mention that it is also effective for other plants of the genus Lycoris. (2) In the background technology, the culture solution soaks the cut cue ball and becomes waste liquid. If it is not effectively utilized, it will pollute the environment if it is discarded, and it will increase the processing cost. (3) The operations in the background technology are all manual operations, with slow speed and low benefit, and cannot be industrialized. (4) In the background technology, the adventitious buds are induced Carried out in matrix soil, the cost is higher

Embodiment 1
[0025] Embodiment 1, the preparation of nutrient solution:
[0026] (1) Prepare 360 liters of disinfectant: In 360 liters of disinfectant, 7200g of carbendazim with a concentration of 80%, 7200g of thiram, and 3600ml of 84 disinfectant are weighed and dissolved in water according to the proportion.
[0027] (2) Prepare 35 liters of medium solution: Take 4.9 liters of B5 medium, 25.6 liters of 6BA with a concentration of 0.1 mg / l, and 4.5 liters of 0.15 mg / L IAA, and mix well.
[0029] Finally, 360 liters of disinfectant solution, 35 liters of medium solution, and 605 liters of growth regulator were mixed to obtain 1000 liters of culture solution, and the above culture solution was diluted 1000 times with water for soaking the cue ball.
Embodiment 2
[0030] Embodiment 2: Select 10,000 Lycoris bulbs with a diameter of 5.0-5.5, and cut them down from the top of the base plate in the shape of a rice on the special cutting machine for bulbs of Lycoris bulbs, and the cutting depth is 1 / of the height of the cue ball. 2 to 2 / 3; the cut cue balls are soaked in the culture medium for 30 minutes, removed and dried in the shade; the shade-dried cue balls are tightly planted on the hydroponic pipeline, and diluted 5000 times with the above-mentioned culture medium waste liquid soaked in the cue balls, Adventitious buds were induced by curing for 3 months; the adventitious buds that had developed leaves were scattered and transplanted to the cultivation soil in the greenhouse, and the seedlings were harvested after 5 months of curing. 145,000 Lycoris plant seedlings were obtained, and the multiplication ratio was 1:14.
Embodiment 3
[0031] Embodiment 3: Select 10,000 Lycoris bulbs with a diameter of 5.0-5.5, and cut them down from the top of the base plate in the shape of a rice on the special cutting machine for bulbs of Lycoris bulbs, and the cutting depth is 1 / of the height of the cue ball 2 to 2 / 3; the cut cue balls are soaked in the culture medium for 30 minutes, removed and dried in the shade; the shade-dried cue balls are tightly planted on the hydroponic pipeline, and diluted 5000 times with the above-mentioned culture medium waste liquid soaked in the cue balls, Adventitious buds were induced by curing for 3 months; the adventitious buds that had developed leaves were scattered and transplanted to the cultivation soil in the greenhouse, and the seedlings were harvested after 5 months of curing. 145,000 Lycoris plant seedlings were obtained, with a multiplication ratio of 1:14.5.

Abstract
The invention discloses a method for rapid propagation of lycorisplant seedlings through hydroponics and aims at providing a lycorisplant asexual rapid propagation method with high reproductive rate for industrialization production of the lycorisplant seedlings. The technical scheme comprises mechanical cutting and induction of adventitious shoots through water pipelines. The method includes following steps: (1) cutting seedballs on a special lycoris seedball cuttingmachine according to a shape of a Chinese character mi; (2) soaking mother balls in culture solution for 30 minutes, fishing out and drying in shade; (3) inducing adventitious shoots through the water pipelines; and (4) transplanting in a greenhouse. The method for rapid propagation of lycoris plant seedlings through the hydroponics can greatly improve reproductive rate of lycoris aurea, reproduction ratio of one mother ball is 14 times of that of a natural son ball, and the method is suitable for industrialization large-scale production of the lycoris plant seedlings.
Description
technical field [0001] The invention belongs to the field of agricultural science and technology, and relates to a method for propagating plant seedlings, in particular to a method for quickly propagating Lycoris plant seedlings by hydroponics. Background technique: [0002] Amaryllidaceae (Amaryllidaceae) is a genus endemic to my country and some countries in East Asia. Its characteristics are relatively stable and it is a perennial herb. Amaryllidaceae plants have attracted the attention of pharmaceutical researchers from all over the world because they contain a variety of alkaloid components with biological and pharmacological activities. Lycoris plants have been used as medicine for a long time. According to the "Compendium of Materia Medica" records, Lycoris plants have the functions of detoxification, phlegm, diuresis and emetic. The chemical constituents of Amaryllis mainly include alkaloids and flavonoids. [0003] At present, the breeding methods of Amaryllis pl...
