Problems solved by technology

[0003] The propagation of Polygonum multiflorum includes cutting propagation and tuber propagation. The tuber root of Polygonum multiflorum takes a long time to form, and it usually takes 2-3 years to form, and root propagation will lead to the degradation of Polygonum multiflorum species, and the increasing damage of diseases and insect pests will seriously affect the yield and quality of Polygoni multiflorum. The quantity is large and the breeding time is long, so it is difficult to meet the needs of major enterprises for Polygonum multiflorum seedlings. This method is not conducive to the propagation and promotion of Polygonum multiflorum. However, cutting propagation is easy to operate, has a high survival rate and short seedling time, and can meet the needs of a large number of seedlings.

Abstract

The invention discloses a cuttage reproduction method of polygonum multiflorum. According to the cuttage reproduction method, lignified twigs of polygonum multiflorum which healthy grows for half a year to two years are taken as cutting slips, the cutting slips are specially processed, fertilizers are reasonably screened, and a proper cottage method is utilized, so that the survival rate of the cut polygonum multiflorum exceeds 95%, and high-quality seedlings can be provided for the field production of the polygonum multiflorum; and furthermore, the whole process is simple, the operation is simple, the breeding cycle is short, and the polygonum multiflorum can be transplanted after 30-45 days. The cuttage reproduction method is completely applicable to field cultivation.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a cutting breeding method of Polygonum multiflorum. Background technique [0002] Polygonum multiflorum, also known as Polygonum multiflora, Purple Wuteng, Night crossing rattan, etc., is a perennial winding vine of the Polygonum family Polygonum genus, with thick roots, oblong, dark brown. It grows thickets in valleys, forests on hillsides, rock crevices on the edge of ditches. Produced in Guizhou, southern Shaanxi, southern Gansu, East China, Central China, South China, Sichuan, and Yunnan. Its roots are used as medicine, which can calm the nerves, nourish blood, activate collaterals, detoxify (cut malaria), and eliminate carbuncles; making Shouwu can nourish essence and blood, black beard and hair, strengthen muscles and bones, and nourish liver and kidney. It is a common precious Chinese herbal medicine. The consumption of Polygonum multiflorum is increasing year by y...
