Panax notoginseng introduction and cultivation method suitable for Guizhou

Abstract

The invention discloses a panax notoginsengintroduction and cultivation method suitable for Guizhou. The method comprises the following steps of (1), land selection, deep ploughing and land preparation, specifically, panax notoginseng is not planted in the first two years of the selected land; (2), firstly applying a base fertilizer; (3), sowing or transplanting; (4), building a sunshade net, and adjusting the light transmittance to 12%-30%; and (5), performing field management. By means of the panax notoginseng introduction and cultivation method, the panax notoginseng can be successfully introduced and cultivated in Guizhou, stability and high yield are achieved, and it is guaranteed that the quality of medicinal materials conforms to pharmacopoeia regulations; the problems that the suitable planting area of a genuine production area is reduced year by year and the panax notoginseng cannot be massively produced due to long crop rotation years of the panax notoginseng are solved; and the introduction and cultivation method suitable for the panax notoginseng in a Guizhou area is explored, agricultural development in the Guizhou area is promoted, and the supply amount of the panax notoginseng in the market is further guaranteed.

Description

technical field [0001] The invention relates to traditional Chinese medicine cultivation techniques, in particular to a method for introducing and cultivating Panax notoginseng suitable for Guizhou. Background technique [0002] Panax notoginseng has a long history of cultivation (Wang Ting et al, 2016). It is an earlier domesticated medicinal plant with a history of more than 600 years of artificial cultivation (Hao Qingxiu et al., 2014). In the "Red Catalog of Biological Species in Yunnan Province" (Cui Xiuming et al., 2014) clearly indicate: wild notoginseng is extinct, so the current notoginseng medicinal materials all originate from artificial cultivation. Yunnan is the main producing area of ​​Panax notoginseng. In 2017, the planting area in Yunnan reached about 450,000 mu, accounting for more than 98% of the national planting area (Cui Xiuming et al., 2018). Wenshan is currently the main producing area of ​​Panax notoginseng, and the area of ​​production is about 8000...

AI Technical Summary

Problems solved by technology

[0004] Meng Xiangxiao et al. (2016) analyzed the ecological suitability of Panax notoginseng global production areas using the "Global Origin of Medicinal Plants Ecological Suitability Information System" (GMPGIS), and pointed out that Guizhou is the most suitable cultivation area for Panax notoginseng. Guizhou is the most suitable cultivation area for Panax notoginseng, and it is an ideal province for the introduction and expansion of Panax notoginseng. However, the growth of Panax notoginseng is relatively harsh to the environment. Although Guizhou has begun to introduce Panax notoginseng more than 20 years ago, it has not yet formed Large-scale production, and there is no report on the correlation between the growth conditions, quality and yield data of Panax notoginseng, and there is no technical guidance on the cultivation of Panax notoginseng specially developed for Guizhou's climate, soil, light and other conditions

Therefore, although many farmers in Guizhou try to plant Panax notoginseng on different scales, due to changes in geographical conditions such as altitude, temperature, humidity, and soil, the nutrients and light conditions suitable for the growth of Panax notoginseng in Yunnan are not applicable in Guizhou, and they are copied mechanically from Yunnan. It is necessary to study the most suitable cultivation conditions for the cultivation of Panax notoginseng in Guizhou, and come up with a cultivation method that takes into account the yield and the quality of medicinal materials, so as to effectively promote local agricultural technology. economy
