摘 要: | 该文以田七原产地云南文山地区的土壤为对照,对比分析了韶关南雄、始兴、从化流溪河地区田七产区的土壤肥力情况,旨在为其他田七产区的施肥管理提供理论指导和科学依据。结果表明:韶关南雄和始兴、从化流溪河地区田七土壤的有效磷普遍缺乏,需要加大磷肥的施用;从化流溪河地区田七土壤的碱解氮相对较低,要注意及时补充氮肥;韶关南雄、始兴地区田七土壤的速效钾含量较低,需要不同程度的补充钾肥。

Comparison of Soil Fertility among Different Producing Areas of Panax notoginseng |

Abstract: | This paper analyses soil fertility of three area including Nanxiong,Shixin and Liuxihe in Gudong province, and compares soil fertility of three area with Wenshan of Yunnan Province,the origin of Panax,to provide theory for Panax fertilization. The results show that the soil available phosphorus is deficiency in Nanxiong,Shixin and Liuxi?he,applies phosphate fertilizer is neccessary. Alkali-hydrolyzable nitroge content is relatively low in Liuxihe and ap?plication of nitrogen fertilizer is the key in this area. Application of potassium fertilizer in Nanxiong and Shixin for these areas is very low. |
