Embodiment 1

[0033] Embodiment 1. Sexual reproduction seedling raising and planting

[0034] 1. Seed Selection and Processing

[0035] 1.1 Seed selection: the fruit is an achene, oblong with 3 wings, 3-lobed calyx remains at the base, and only 1 seed is contained inside the fruit; the peel is thin, with hilums of different lengths, the surface is smooth and hairless, and the whole fruit is Brown with shrunken wings; fruit length 8.2mm, width 3.11mm; seeds length 4.77mm, width 1.99mm; thousand seeds weigh 12.9g, water content 6.51%.

[0036] 1.2 Seed soaking: Soak the seeds in water at 15°C-20°C for 24 hours to make them fully swell, remove and drain the water.

[0037] 1.3 Acceleration of germination: the mass concentration of fully expanded seeds is 50×10 -6 g / L gibberellin (GA 3 ), 6-benzylaminopurine (6-BA), kinetin (KT) one of the three rooting hormones to accelerate germination for 24 hours. The rooting hormone is preferably gibberellin (GA 3 ).

Embodiment 2

[0053] Embodiment 2. Cloning and planting

[0054] Choose the complete rhubarb with strong advantages, complete buds, and no pests. Cut the root head 10 cm away from the upper end of the root head, and then cut it into small pieces according to the bud head. The weight of each small piece is ≥150g. It can be directly planted in the field. Planting, management and excavation were carried out according to Example 1.

Abstract

The invention discloses a wild culture-imitating method for rheum officinale baill. The method is characterized by planting seedlings subjected to sexual reproduction and seed blocks subjected to asexual reproduction in an adret sloping field with a high altitude of 1,500 to 1,800 m and a gradient of less than or equal to 30 degrees and performing extensive management by a wild-imitating method, wherein the seedlings subjected to sexual reproduction is cultured in an adret flat field with a low altitude of 800 to 1,000 m; during seedling culture, the thousand seed weight is more than or equal to 12.9 g, the moisture content is lower than 6.51 percent and the purity is over 98.9 percent; after immersion and germination acceleration, the seeds are sown on a seedbed; after the seedlings grow to be 10 centimeters high and the ground diameter is more than 2 centimeters, the seedlings are transplanted; the transplanting time is the first ten days of April every year; farmyard manure subjected to innocent treatment is applied one time per year; and after three years, the rheum officinale baill can be harvested. The invention provides a practicable method for realizing large-area standard plantation of the rheum officinale baill. By the method, the yield and the quality of the rheum officinale baill can be improved; and all the officinal active ingredients of the product are over 1.5 percent.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for imitating wild cultivation of medicinal rhubarb. Background technique [0002] Medicinal rhubarb (Rheum Offieinale Baill) is well-known as a traditional Chinese medicine laxative and stomachic medicine. Its medicinal active ingredients include emodin, chrysophanol, rhein, emodin methyl ether, aloe-emodin, etc. [0003] For a long time, medicinal rhubarb has been a wild plant. Although some people have planted it sporadically in recent years, they are all extensive. First, the output is low. Second, the quality of the finished products is uneven, and most of them are of poor quality. Contents of the invention [0004] The object of the present invention is to propose a method for imitating wild cultivation of medicinal rhubarb, which can not only keep the quality of wild medicinal rhubarb as much as possible, but also realize large-scale planti...
