A method for industrialized cultivation of a new hybrid variety of Platycodon grandiflorum Zhonggeng No. 2

Abstract

The invention discloses a method for industrially planting a new hybrid Chinese bellflower variety Zhonggeng 2. The method comprises the steps of: reproducing parents, producing hybrid seeds, determining row ratio and sowing date of the parents, removing impurities and roguing, building an industrialized planting model base, and the like, wherein the building of the industrialized planting model base comprises the steps of: site selection, sowing, thinning, fertilizer application during a seedling stage, irrigation, flower removal, weeding, prevention and control of disease, pest and rat disasters, harvest processing and storage transportation, processing in a production place, packaging storage transportation and the like. According to the method, the industrial level can be promoted, the industrialization of platycodon medicinal material production is realized, and the quality of the medicinal material and the requirements of the masses on safe medicine application are guaranteed. Zhonggeng 2 is a high-yield and high-quality new hybrid platycodon variety and has strong competitiveness in platycodon varieties. Under the current conditions of research on raw platycodon resources and shortage of raw materials, the method can be implemented for alleviating the shortage condition of platycodon in the market and promoting the protection and the sustainable utilization of resources; and the method has good economical and social benefits.

Description

technical field [0001] The invention belongs to the technical field of plant planting methods, and in particular relates to a method for industrialized planting of a new hybrid Platycodon grandiflorum variety Zhonggeng No. 2.

Problems solved by technology

[0004] With the development of science and technology, the number of medicines and health care products using bellflower as raw material is increasing, and its application is becoming more and more extensive, and the market demand is increasing. my country needs about 8,000-10,000 tons of bellflower dried products every year. my country's existing bellflower is planted in With a land area of ​​80,000 mu and an annual output of more than 50,000 tons of fresh products, there is a big gap between supply and demand. In recent years, due to years of continuous cropping, poor industrialization, and low production technology, the planting of bellflowers has degenerated varieties, low yields, and poor yield quality. Problems such as decline, serious weed damage and underground pests, low level of mechanization, and high labor costs have seriously affected the income of local farmers planting platycodon grandiflorum, and platycodon grandiflorum has become a medicinal material that is in short supply in the market
