三七持续种植关键技术

针对三七产业存在的技术瓶颈，本文聚焦三七新品种选育、连作障碍克服、标准体系建立等方面，采用生物技术、信息技术等手段，从产区选择、田间管理、收获储藏等过程实现数字化、网络化，解决三七种植中精准选址、品种选育、土壤改良、施肥管理、病害防控等关键问题，实现三七栽培的精准化及最优化，建立了三七 持续种植复合技术体系，该体系包括：三七抗病新品种的选育、土壤复合改良技术、三七栽培技术及质量追溯技术。获得首个三七抗病新品种，为其持续种植提供可行性前提。建立三七连作土壤复合改良技术并应用于大 田，连作土壤的修复及改良为三七持续种植提供保障。发布了首个无公害三七质量标准，为其高品质树立规 范。完成了品质溯源体系，保障了三七的质量可控。该复合技术体系为其它中药材精细栽培提供借鉴。

Pivotal Technology of Panax notoginseng Continuous Cropping

Research teams work together to solve the technical bottleneck in the Panax notoginseng industry. These research directions mainly focus on breeding of new variety, alleviating the continuous cropping obstacles, building standard system and so on. We used methods such as biotechnology, information technology and so on, to realize digitization, network and intellectualization in the process of selection of producing areas, field management, harvest storage, solved key issues of the precise selection of producing areas, variety breeding, soil improvement, fertilization management, and realized the precision and optimization of ginseng cultivation. We built the composite technology system of pollution-free notoginseng. This technology system mainly contained the breeding of new cultivar, the composite technology of soil improvement, the cultivation system of pollution-free notoginseng and quality traceability system. A new disease-resistant cultivar of notoginseng was bred, which offered feasibility for the notoginseng continuous cropping. We first presented composite improvement technology of notoginseng continuous cropping soil. This improvement technology has been used in the field. This technology system of soil restoration and improvement guaranteed notoginseng continuous cropping. A first standard system of pollution- free notoginseng was issued. It established standard of high- quality notoginseng materials. Finally, quality traceability system of notoginseng was finished, which safeguarded the controllable quality.This composite technology system offers references for the cultivation of other Chinese herbal medicines.
