Rhizoma Paridis is still mainly from the wild, and there is no large-scale artificial planting product. With the rapid development of Chinese medicine industry, the amount of drugs used by the production enterprises with Paris polyphylla as raw materials has increased greatly, and the long-term predatory mining has made the wild Paris polyphylla less and less. It takes 8-1 years for Paris polyphylla to be planted, harvested and utilized. In order to obtain more raw materials, pharmaceutical enterprises have greatly increased the purchase price of Paris polyphylla, and the purchase price has reached more than 1 yuan /kg. With the increase of purchase price, the enthusiasm of drug farmers for mining and excavation has far exceeded the natural growth rate, resulting in the scarcity of Paris polyphylla resources. According to the data, 8% of the wild Paris polyphylla distributed in China has been developed and utilized, leaving only 2% of the resources. China consumes more than 1 tons of heavy buildings every year, and all of them are wild heavy buildings. The existing resources may be exhausted after about 5 years of excavation. The scarcity of Paris polyphylla resources may become a bottleneck restricting the sustainable development of related pharmaceutical industries in Yunnan. Therefore, relying solely on wild resources is far from meeting the market demand, and artificial planting has become an inevitable choice to solve the shortage of resources in Paris. Moreover, with the continuous expansion of the Chinese herbal medicine market and the good efficacy of Paris polyphylla, the demand for Paris polyphylla will inevitably increase substantially, and the price will rise.
in may, 211, hosted by the provincial department of science and technology, the key new product plan "research and application demonstration of superior provenance breeding and three-stage cultivation method of Paris polyphylla var. yunxin in Lijiang" (28BC3), which was undertaken by the Institute of Medicinal Plants of Yunnan Academy of Agricultural Sciences and studied by Lijiang Yunxin Green Biological Development Co., Ltd. and the Institute of Alpine Economic Plants of Yunnan Academy of Agricultural Sciences, was accepted and the results were identified. The Party Committee and Deputy Secretary Zhenyuan of the Provincial Science and Technology Department presided over the acceptance, and Director Qin Mu of the Award Office presided over the appraisal of the results. Levin, a deputy researcher of the Social Development Department, and Qu Yunhui, deputy director of the Scientific Research Department of the Provincial Academy of Agricultural Sciences, attended the meeting. Paris polyphylla var. yunnanensis is the main raw material of Gongxuening, Reduqing, antiviral granules and Jidesheng snake tablets. In view of the fact that the growth cycle of Paris polyphylla var. yunnanensis in production is as long as 9 ~ 1 years, the project has innovated the three-stage cultivation method and formulated the corresponding standardized cultivation rules of the three-stage cultivation method. Breeding and registering two new disease-resistant varieties "Dianchonglou No.1" and "Dianchonglou No.2" with high content of effective components and high yield; The technical system of large-scale seedling raising of Paris polyphylla var. yunnanensis seeds was established. The occurrence regularity of leaf spot of Paris polyphylla var. yunnanensis was clarified, and the effective control methods were put forward. Two local standards of Yunnan province, namely "technical regulations for variety evaluation of Paris polyphylla var. yunnanensis" and "technical regulations for three-stage cultivation of Paris polyphylla yunnanensis", were formulated. Obtained two invention patents: "a method of artificial three-stage cultivation of Paris polyphylla" and "a method that can effectively prevent and control leaf spot of Paris polyphylla in Yunnan"; He published 11 papers and compiled 2 series of high-quality and high-yield cultivation techniques, which provided important reference for the scientific research and production of Paris polyphylla var. yunnanensis. At present, a demonstration base of "three-stage cultivation method" of Paris polyphylla var. yunnanensis has been established in Yulong county, Lijiang, with an economic benefit of 136.31 million yuan in 21, which has achieved remarkable economic, social and ecological benefits. The study on the breeding of superior provenances of Paris polyphylla var. yunnanensis and the three-stage cultivation method further optimized the variety structure of Paris polyphylla var. yunnanensis, formed a series of varieties, and the variety structure became more reasonable. It has formed an industrial development model of company+base+farmers, which combines scientific research with enterprises, and laid a good foundation for the development of Paris polyphylla, an important Chinese herbal medicine in Yunnan Province. After carefully listening to the report of the project team, consulting the materials, asking questions and discussing, the expert group and the achievement appraisal committee agreed that the research achievements are important and innovative, and the overall level of achievements has reached the domestic leading level.
