Problems solved by technology

Artificial planting has existed for a long time, but due to the induction of economic interests, it was dug in 1 year when it should grow for 3 years, and dug in 2 years when it should grow for 5 years. There is basically no rhubarb in the market that meets the standards of "Chinese Pharmacopoeia"
The state has lowered the statutory index of active ingredients in rhubarb in the 2010 edition of the "Chinese Pharmacopoeia" from the original 2.3 to 1.5, but the content of active ingredients in "1-year fast-growing" rhubarb still does not meet the national standard

Embodiment 1

[0045] Implementation steps 1. Seed collection: Around September 5, 20kg of wild Tangut rhubarb seeds were collected by professionals with more than 10 years of experience in rhubarb planting research on a mountain at an altitude of 3600-3700m in Tanggu Town, Tongde County, Qinghai Province.

[0046] Implementation step 2. Seedling cultivation: Lease 4 mu of land in Azitan Township, Zhuoni County, Gansu Province, with an altitude of about 2300m, and the land is flat. In the first ten days of April, use 3 tons of decomposed manure per mu as the base fertilizer and sprinkle it on the ground, plow it deeply, and make it level. Soak the seeds in warm water at about 23°C the morning before and place them in a warm place. The next day, use a custom-made rake to pull out troughs 3 cm deep and 3 cm wide at a row spacing of 15 cm, and spread the soaked seeds evenly in the troughs , basically one seed per 2cm, and the amount of seeds per mu is about 6.5 kg. Cover the trough with wet so...

Embodiment 2

[0055] Implementation step 1, with embodiment 1

[0056] Implementation step 2, land selection and planting: choose 20 mu in Azitan Township, Zhuoni County in the form of cooperatives, with an altitude of about 2800m, black soil, and the thickness of the soil layer is less than 2 meters. At the end of March, 4 tons / mu of decomposed sheep manure was used as the base fertilizer for deep plowing and leveling. When the moisture content is good, it was fully covered with black agricultural film.

[0057] Implementation steps 3 and 4 start on-demand, about 1600 plants per acre. The day before sowing, soak the seeds in warm water at about 22°C for 25 hours, sow Tangut rhubarb seeds on-demand in the plastic film field, with a row spacing of 65cm and a plant spacing of 50cm, sowing at fixed points. Use a special hollow tool to penetrate the mulch at the sowing point, and dig regular small holes with a depth of 3cm. Put 2 seeds in each hole. After putting the seeds in, use the surround...

Embodiment 3

[0063] Implementation step 1, with embodiment 1

[0064] Implementation step 2, land selection for planting: Plant 100 mu in Guzhan Township, Lintan County by transferring land, with an altitude of 2700-2850m, black soil, and the thickness of the soil layer is less than 2 meters. At the end of March, use 4 tons / mu of decomposed sheep manure or chicken manure as the base fertilizer for deep plowing, leveling, and covering with black plastic film when the moisture is good.

[0065] Implementation step 3, with embodiment 2

[0066] Implementation step 4, with embodiment 1

[0067] Implementation step 5, with embodiment 2

[0068] Implementation step 6, quality traceability: the planting company will number the planting plots and make production records. The produced rhubarb sub-lots will be LTXGZX2016003 according to the production batch number, so that the quality can be traced.

[0069] Through the above 3 examples, at different altitudes, different planting methods, plantin...

Abstract

The invention discloses a five-year-old Rheum tanguticum organic cultivation method, and belongs to the technical field of medicinal plant artificial cultivation. The organic cultivation method includes selecting a plateau alpine wet climatic environmental condition; selecting high altitude wild seeds; performing seedling raising, or directly sowing the seeds; using a plastic film to retain heat, moisture and remove weed in the first two years; mechanically removing weed later; applying an organic fertilizer without farm chemical; enclosing soil and discharging water; removing leaves and sprouts; testing samples after five years; digging the Rheum tanguticum if the test is qualified; and performing numbering and recording to achieve quality tracing. The obtained Rheum tanguticum is high in yield, is good in quality, is low in labor cost, can provide qualified Rheum tanguticum for pharmaceutical enterprises, and can improve the economic income and the planting positivity of farmers.
