Cultivation method of good-quality high-yield Platycodon grandiflorum

Abstract

The invention relates to a cultivation method of good-quality high-yield Platycodon grandiflorum. The cultivation method comprises the steps of selecting a suitable field, seeding scientifically, transplanting reasonably, managing the field reasonably, controlling pests, harvesting, processing, and reversing seed stocks scientifically. A suite of measures of soaking seed through Chinese herb medicine liquid, cultivating seedlings in summer, transplanting in winter, cutting the seedlings in early summer and the like are adopted, quality of the Platycodon grandiflorum is improved, a commodity stripe selection rate is improved, a yield is increased, and economic benefits are improved. During fertilization, organic fertilizer is adopted as main fertilizer, Chinese herb medicine fertilizer is added at the same time, and the cultivation method is green and environment-friendly. In pest control, pesticide with low concentration and little toxicity is adopted, Chinese herb medicine agents are matched simultaneously, pesticide residue is lowered effectively, content of heavy metal of obtained Platycodon grandiflorum finished products is lowered by more than 50% compared with a conventional method, good demonstration effect is achieved, and the cultivation method passes good agriculture practice (GAP) authentication of the national certification and accreditation administration.

Description

technical field [0001] The invention relates to the technical field of Chinese herbal medicine cultivation, in particular to a cultivation method for high-quality and high-yield bellflower. Background technique [0002] At present, the domestic production of Chinese herbal medicines is mainly based on small-scale extensive planting mode with farmers as the main production and management. Pesticide residues and heavy metal content exceed the standard, and the quality is unstable. It is difficult to meet the quality control standards of Chinese herbal medicines, which seriously affects the development of Chinese herbal medicines. . Since the beginning of 2001, the upsurge of medicinal planting in the country has been unprecedentedly high. Local governments have adjusted the local agricultural production structure, positioned the adjustment target on medicinal planting, and vigorously guided farmers to develop large-scale medicinal planting.

Problems solved by technology

[0002] At present, the domestic production of Chinese herbal medicines is mainly based on small-scale extensive planting mode with farmers as the main production and management. Pesticide residues and heavy metal content exceed the standard, and the quality is unstable. It is difficult to meet the quality control standards of Chinese herbal medicines, which seriously affects the development of Chinese herbal medicines.

Since the beginning of 2001, the upsurge of medicinal planting in the country has been unprecedentedly high. Local governments have adjusted the local agricultural production structure, positioned the adjustment target on medicinal planting, and vigorously guided farmers to develop large-scale medicinal planting. On the other hand, the battle of growing medicines, farmers lack the guidance of market information and standardized operation techniques, so that the planting of medicinal materials in many areas deviates from scientific guiding principles, and a blind and unscientific, chaotic and unstandardized situation has emerged. As a result, the quality of medicinal materials is difficult to meet the requirements of standardization, stabilization, green and pollution-free, and it cannot meet the needs of pharmaceutical companies for raw materials of Chinese medicinal materials and the needs of modernization of traditional Chinese medicine.

This leads to plant lodging and low yield
