Special combined fertilizer suitable for introduction and cultivation of panax notoginseng in Guizhou

Abstract

The invention discloses a special combined fertilizer suitable for introduction and cultivation areas of panax notoginseng in Guizhou. The special combined fertilizer comprises a composition I and a composition II, and the composition I is a compound fertilizer for triennial panax notoginseng, wherein the ratio of nitrogen to phosphorus to potassium is 20-25 kg / mu to 16-20 kg / mu to 22-28 kg / mu according to the annual application amount. By adopting the special combined fertilizer, the panax notoginseng can be successfully introduced and cultivated in the Guizhou area, the stable and high yield is realized, and the quality of medicinal materials is ensured to conform to the provisions of pharmacopeia; 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 an introduction and cultivation method suitable for the panax notoginseng in the 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 the technical field of traditional Chinese medicine cultivation, in particular to a special combined fertilizer suitable for the introduction and cultivation of Panax notoginseng in 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, an...

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
