Cutting rapid propagation method for angelica keiskei

Abstract

The invention discloses a cutting rapid propagation method for angelica keiskei and belongs to the field of agricultural technologies. The cutting rapid propagation method for the angelica keiskei is used for simplifying the propagation technology of the angelica keiskei, shortening the propagation period, reducing rapid propagation cost and achieving rapid propagation of the angelica keiskei. The method is mainly used for the medicinal and edible angelica keiskei and includes the detailed steps that stems with the length of 3 cm-5 cm and the thickness of 0.2 cm-0.8 cm are selected and provided with 2-5 compound leaves and 2-5 buds, then the stems are rapidly dipped into rooting powder with 200-400 diluents for 15 seconds-30 seconds, cut into wet sand and watered with sufficient water, under the conditions that the temperature is (25+ / -2) DEG C, the air relative humidity is over 75%, the illumination is 10,000 lx-20,000 lx, and the illumination time is 12 h / d-14 h / d, the stems are cut for 7-15 days, the survival rate is 100%, seedlings which are survival through cutting are transplanted into a land sun-shade shed, the spacing in the rows and the spacing between rows are 20 cm*20 cm, the temperature is 25 DEG C-30 DEG C at daytime, the temperature is 15 DEG C-18 DEG C at night, the air relative humidity is 70%-90%, the shed is appropriately opened for ventilation, and the survival rate reaches 100% at the seventh-tenth day after transplanting. Compared with a tissue culturing rapid propagation technology, the method simplifies the propagation steps, shortens the propagation time and reduces propagation cost, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to a cutting method of perennial herb, more specifically relates to a cutting method of Ashitaba, and belongs to the field of agricultural technology. Background technique [0002] Ashitaba is a perennial herb with both medicinal and edible uses. Its main functional ingredients are chalcones and coumarin compounds, and it is also rich in organic germanium and vitamin B 12 , has the medicinal effects of enhancing immunity, purifying blood, preventing vascular aging, antithrombotic, antibacterial, antiulcer, anticancer, antidiabetic, lowering cholesterol and lowering blood fat; can be eaten as vegetables (stems and leaves can be fried, fried, boiled , frying, stewing, juicing, salad, etc., and the roots are used for making wine), the aroma contained in it can remove the fishy smell of fish and meat, and can also be used for making tea (Qingdao Changlv Technology Development Co., Ltd. developed "Ashitaba Health Tea" " and other seri...

AI Technical Summary

Problems solved by technology

At present, the common propagation method of ashitaba is sowing and reproduction, but because ashitaba needs to be cultivated for 2-3 years before flowering and seeding, the seed setting rate is low, the plant dies immediately after flowering and fruiting, and the seed germination rate is low (45%-50%) , complex procedure, low reproduction coefficient (one seed multiplies into one plant), etc., in order to further expand the scale of industrialized production of Ashitaba, it has been reported that rapid propagation is carried out by tissue culture. Li Jia et al. The regenerated plants of Ashitaba were induced, and the cycle was about 4-5 months; Guo Zhiyou et al. induced the regenerated plants through the leaves through the callus, and the cycle was about 6 months; Liu Mengxin, etc. used tissue culture technology to directly induce budding and rooting through the leaves Plants are formed, and the period is about 2 months; Cao Yueping uses tissue culture technology to produce callus through leaves and petioles to further form somatic embryos, which grow new plants after germination, and finally cultivate the new plants after rooting Rooting on the basis; Lu Xiuli et al. used Ashitaba seeds as explants to obtain sterile seedlings, multiplied, rooted, and bottle-hardened seedlings to obtain plants after transplanting, and established a tissue culture system for Ashitaba, with a cycle of about 2-3 month
