High-yield cultivation method for platycodon grandiflorus

Abstract

The invention discloses a high-yield cultivation method for platycodon grandiflorus. The method comprises the following steps: (1) selecting land and preparing soil; (2) performing sowing: in the middle and late October, uniformly mixing seeds by using plant ash, and performing sowing in a broadcast sowing manner; (3) performing field management, wherein field management includes daily managementsuch as weeding, fertilizer and water management, disease and pest prevention and control and flower bud removal; and (4) performing harvesting: in the autumn of a second year of growth, after stems and leaves on the ground are withered, digging underground rhizomes. The method provided by the invention starts from treatment before seed sowing, field management after sowing and real-time harvesting to improve the yield and quality of the platycodon grandiflorus, reduce the use amount of chemical fertilizers and reduce planting costs, and thereby increasing economic benefits of growers.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine planting, in particular to a high-yield cultivation method of bellflower. Background technique [0002] Campanulaceae, also known as soil ginseng, bell flower, is a plant of Campanulaceae, Campanulaceae, a perennial herb. Platycodon grandiflorum is a kind of medicine and food. It uses underground rhizomes for medicinal purposes.

AI Technical Summary

Problems solved by technology

Because bellflower has high edible, medicinal and economic value, the artificial planting of bellflower is more and more favored by growers. However, the current planting of bellflower is not standardized, and the growth process of bellflower is improperly managed. Insufficient ingredients, coupled with problems such as diseases and insect pests, lead to low yields of platycodon grandiflorum and unsatisfactory economic returns
