[0019] Example 1, a method of artificially cultivating rhubarb
[0020] 1. Site selection and site preparation Rhubarb is a deep-rooted plant. The main root can penetrate 30 to 45 cm into the soil layer. The site selection is preferably loose and well-drained sandy soil hillside. After harvesting the previous crops such as corn and potatoes, combine Apply enough base fertilizer for deep plowing, and apply 4,000 to 5,000 kilograms of manure per mu. On poor soil, the amount of fertilizer can also be increased.
[0021] 2. The propagation method adopts the method of seed propagation, seedling cultivation and transplanting
[0022] The seedlings of rhubarb are transplanted in a well-made high bed with a width of 1.2 meters and a length of 21 meters, and drainage ditches are opened on all sides. Ditch and drill horizontally on the furrow with a row spacing of 12 cm and a depth of 5 cm. Spread the seeds evenly into the ditch, cover the nutrient matrix humus with 2 to 3 cm, and then...

Abstract
A method for manually culturing rheum palmatum is a seeding seedling transplantation method. The method is characterized by comprising the steps of arranging a high rectangular piece of land with the width of 1.2m and the length of 21m in land tidied well, and arranging drainage ditches well on four sides; performing ditching on the rectangular piece of land horizontally to perform sowing in line, enabling the line spacing to be 12cm, enabling the depth to be 5cm, evenly scattering seeds in the ditches, covering the seeds with nutritious matrix humus which is 2-3cm deep, covering the nutritious matrix humus with a layer of grass, and uncovering the covering grass after sprouts are unearthed. The rheum palmatum is a deep-rooting plant, a main root can go deep into a soil layer for 30-45cm, loosened and well-drained sandy loam hilly land is preferable for land selection, base fertilizer is fully applied by combination with deep ploughing after preceding crops such as corn and potatoes are harvested, 4000-5000 kg of farmyard manure is applied per 0.16 acre of land, and the fertilizing amount can be added for poor soil. By adopting the seedling transplantation method, the planting yield of the rheum palmatum can be greatly improved, farmers who plant the rheum palmatum can have good planting benefits, and a way is explored for large-scale plantation of the rheum palmatum by the farmers.
Description
technical field [0001] The invention relates to the technical field of Chinese herbal medicine cultivation, in particular to a method for artificially cultivating rhubarb. Background technique [0002] Rhubarb is the dry root and rhizome of Rheum palmatum L., R. tanguticum Maxim ex Balf., and medicinal rhubarb (R. officinale Baill.), also known as Shengjun, General, Sichuan Army. Nature and flavor are bitter, cold. It has the effects of purging excess heat, lowering stagnant stagnation, removing blood stasis and detoxifying. It is used for symptoms such as excess heat constipation, stagnant abdominal pain, damp-heat jaundice, acute appendicitis, and incomplete intestinal obstruction. It is mainly produced in Qinghai, Gansu, Sichuan, Shaanxi and other provinces. Its morphological characteristics are that it is a perennial herb of Polygonaceae, with hypertrophic root flesh, lignified, non-branched, radish-shaped, and some with several forked, bull-headed. Stems erect, unb...
