Problems solved by technology

[0007] Epimedium is a panicle, which gradually blooms and bears fruit from bottom to top. The seed maturity time varies greatly, and the seeds are small (thousand-grain weight 2.9-6.2 grams). It is not easy to collect seeds and the cost of breeding is high. In addition, Epimedium seeds also have the characteristics of deep physiological dormancy , the natural dormancy time is long, the dormancy rate is low, and it is not easy to grow seedlings. Therefore, although the problem of seed germination has been solved at this stage, the level of seedling cultivation is still very low. A large number of seedlings, the actual rate of seedlings obtained is very low, and the waste of seeds is serious, resulting in high seedling cost

Embodiment 1

[0038] Embodiment 1 Seedling-raising matrix mixing soil ratio selection experiment

[0039] By setting different seedling substrates (substrate ingredients are seedling substrates produced by Guizhou Bailing Group Biotechnology Fertilizer Co., Ltd., and the components are decomposed medicinal residues, peat, perlite) mixed with soil (substrate ingredients: the volume ratio of soil is 1:0 respectively) , 2:1, 1:1, 1:2, 1:3,) after mixing in the ratio, add appropriate amount of water and stir to form a mixed soil that is hand kneaded into a ball and then sprinkled as seedling soil, and the seedling on-demand test is carried out.

[0040] Comprehensively compare the emergence rate of each test setting, the moisture retention and hydrophobicity of the nursery soil (see the table below).

[0041] Table of observation results of seedling raising with different soil mixing ratios

[0042]

[0043] The results showed that Epimedium seedlings were mixed with matrix: soil 2:1-1:2 to...

Embodiment 2

[0044] The comparative experiment of embodiment 2 and traditional seedling raising mode

[0045] Use the present invention to compare with the traditional way of raising seedlings. Seed collection and storage methods are consistent with the method (Chinese patent application 201110082297.7) used by the applicant before, that is, collecting the Epimedium seeds from May to June, and mixing the collected seeds with clean fine river sand through a 50-mesh aperture sieve by weight Mix evenly at a ratio of 1:10, and store in a cool place. It can be sown after 5 months of sand storage.

[0046] Seedling pot seedling cultivation of the present invention is carried out as follows:

[0047] Step 1, seed preparation: in early December, wash the seeds from the fine sand with clean water before sowing the seeds stored in the sand;

[0048] Step 2. Configure seedling substrate: The volume ratio of substrate ingredients to sand and soil is 1:2; 1:1 and 2:1 respectively. Add appropriate am...

Embodiment 3

[0060] Embodiment 3 uses kind amount comparative test

[0061] Choose a flat ground with shading conditions as the seedbed, and divide it into 1m 2 According to the method of embodiment 2, the seedlings were sown in the 6 regions, and the breeders analyzed and counted the seedlings in the 6 regions respectively, and the results are shown in the table below.

[0062] Contrast test results with species

[0063]

[0064] The amount of seeds used for raising seedlings in the present invention is far less than that of traditional sowing seedlings, and the amount of seeds used for traditional sowing seedlings is 5.0-8.0g / m 2 , the seedling dosage of the present invention is 0.7~2.1g / m 2 .

Abstract

The invention provides a high-quality seedling culture method of Epimedium sagittatum. According to the method, seedling bowls / hole cups are adopted for seedling raising, seedling culture substrate selection and field management during seedling culture are combined, the emergence rate of Epimedium sagittatum seeds can reach 95%, and the transplanting survival rate of seedlings reaches 99% or above. In the field of Epimedium sagittatum medicinal material planting, the seedling culture method is initiated in China, the seedling culture level of Epimedium sagittatum is greatly improved, the seedconsumption is far smaller than that of a traditional broadcast sowing seedling culture mode, the seed consumption of traditional broadcast sowing seedling culture is 5.0-8.0 g / m<2>, the seed consumption of seedling culture is 0.7-2.1 g / m<2> in the invention, and the seedling formation rate is also greatly increased; seedlings can be transplanted with soil, the transplanting survival rate is higher, the recovery growth vigor is high, success is achieved under the field condition at present, the problem that development of the artificial Epimedium sagittatum planting technology is restricted issolved, and remarkable progress is achieved.

Description

technical field [0001] The invention relates to the technical field of planting Chinese medicinal materials, in particular to a seedling raising method of epimedium. Background technique [0002] Epimedium sagittatum (Sieb. et Zucc.) Maxim. is a perennial herb of the genus Epimedium L. in the family Berberidaceae. It is one of the important traditional medicinal plants in my country. It has been recorded in Shennong’s Materia Medica, traditionally used for tonifying kidney and strengthening yang, strengthening muscles and bones, and dispelling rheumatism. It is also used clinically to treat diseases such as osteoporosis, menopausal syndrome, hypertension, coronary heart disease, and inhibit tumors. [0003] Along with increasingly extensive medicinal demand, the demand to Epimedium is also increasing, so it is necessary to develop the artificial cultivation technology of Epimedium. [0004] In artificial cultivation technology, breeding technology is a very critical part. T...
