Method for propagating kalimeris indica by adopting rhizome

Abstract

The invention relates to a plant culture technology, in particular to a method for propagating kalimeris indica by adopting rhizome. The method is characterized in that the kalimeris indica rhizome is dug before the winter, is cut into small sections with the length being 5-8cm and is flatly paved on the bottom of a ditch with the depth being 10cm after the soil preparation, the line distance is 20cm, the strain distance is 10cm, the soil is covered, and the compact pedaling is carried out; after the harvesting completion in April to May in spring, the strains are dug out with the roots, old roots are sheared away, lateral bud parts with the roots are transplanted into the prepared ridge surfaces according to the strain distance being 25cm, three to four strains are planted in each hole, the compact pedaling is carried out, sufficient water is watered, and the buds can survive after 5-7 days; the planting is carried out in August to September in autumn, underground perennial roots are dug, 10-15cm is left over the ground, old branches and old roots are sheared away, the strains are planted onto the ridge surfaces, the cross dressing is carried out in time after the survival so as to promote the tillering. The method provided by the invention has the beneficial effects that the defects of the wild kalimeris indica propagation are overcome, the detects of the technology for artificially planting the kalimeris indica in northwest regions in China are overcome, the rhizome propagation is adopted, the planting scale and the yield of the kalimeris indica are improved, the propagating method is simple, the survival rate is high, and the method belongs to the planting projects capable of helping farmers overcome poverty and achieve prosperity.

Description

technical field [0001] The invention relates to plant artificial cultivation techniques, in particular to a method for propagating Malan by using rhizomes. Background technique [0002] Malan, also known as Malantou, red stalk dish, chicken intestines, and roadside chrysanthemum, is a plant of the genus Malan in the family Asteraceae. Its botanical characteristics are perennial herbaceous plants, the plants are short and clustered. Stems 30-70cm high, erect, purple-red or turquoise, 0.4cm in diameter, branched. There are red stalks and green stalks in wild Malan, but the red stalk has a strong fragrance. The leaves are oblanceolate, alternate, dark green in color, 3 to 10 cm long and 1 to 5 cm wide, with serrated or lobed edges, and purple or dark green veins. The leaves are smooth or rarely short-haired, and the upper leaves are small and entire. Inflorescence head, about 2.5cm in diameter, solitary on branches and arranged in sparse corymbs, 2-3 layers of involucre, ye...
