Tubular hole drilling and substrate filling cultivation method for burdock (Arctium lappa L.)

Abstract

The invention discloses a tubular hole drilling and substrate filling cultivation method for burdock (Arctium lappa L.). The method includes the following steps: A cultivation land is irrigated; when the soil humidity reaches about 60 percent 1 to 3 days after land irrigation, ridging is carried out by a ridging machine to achieve ridges with a line spacing of 60 to 70 centimeters, a width of 15 to 20 centimeters, and a thickness of 130 to 150 centimeters, and 80% of soil is returned to furrows; holes are drilled, i.e., vertical holes with the diameter of 8 centimeters and the depth of 150 centimeters are drilled in the cultivation land, and the distance between hole centers is 10 centimeters; the vertical holes are filled with fertilizer-doped substrate, that is, the substrate is uniformly doped with fertilizer necessary for the burdock growth; burdock seeds are sowed on the substrate in the vertical holes; the planted burdock seeds are covered with soil with the thickness of 2 centimeters, and the covering soil is slightly lower than the ground. The method achieves integrated fertilization and irrigation, the burdock can easily grow along cultivation tubes, the cultivated burdock has strong and very straight roots, and the commodity quality and the commodity rate are high.

Description

technical field [0001] The invention relates to a burdock cultivation method, in particular to a burdock tubular perforated substrate filling cultivation method, which belongs to the technical field of traditional Chinese medicine cultivation. Background technique [0002] Burdock is a herbaceous taproot plant of Compositae, a biennial herb, with thick fleshy taproots, up to 15 cm long and 2 cm in diameter, branched roots, erect stems, strong, with a base diameter of 2 cm, usually with Purple red or lavender red, with many raised ribs, diverging obliquely, numerous, all stems and branches are covered with sparse papillary short hairs and long spider silk hairs mixed with brownish yellow glandular spots, basal leaves are wide Oval, up to 30 cm long, up to 21 cm wide, shallowly wavy concave teeth or tips with sparse margins, heart-shaped base, petiole up to 32 cm long, heterochromatic on both sides, green above, with sparse short strigose and Small yellow glandular spots, off...

Problems solved by technology

[0007] At present, the cultivation method of burdock is usually the direct seeding method or the seedling raising and transplanting method, and the direct seeding method is the main method. Generally, the burdock cultivated on the soil, due to the uneven soil texture, the growth of the burdock is uneven, some are thick, others are thin, and some are thick. The straight ones have some bends, and the commerciality is relatively poor
