对德江天麻种植基地土壤p H、养分含量调查和分析,结果表明:土壤属弱酸性环境,较适宜天麻种植要求;土壤有机质、全氮、碱解氮含量较为丰富,属土壤肥力2级水平,为天麻高品质、高产量提供天然优势;缓效钾、速效钾含量稍缺乏,属土壤肥力4级水平,可能会影响到天麻的正常生长。建议合理施用天麻专用化肥,适量补充钾肥、合理施用微生物肥料、科学合理规划种植、注重栽培管理。
The results showed that soil is a weakly acidic environment, which is more suitable for planting Tianma. The content of soil organic matter, total nitrogen and available nitrogen is relatively abundant, which belongs to the second level of soil fertility. Tianma high-quality, high yield to provide natural advantages; slow-acting potassium, a little lack of available potassium, soil fertility level 4, may affect the normal growth of Gastrodia. Proposed rational use of gastrodia fertilizer, appropriate amount of potash fertilizer, the rational use of microbial fertilizer, scientific and rational planning and planting, pay attention to cultivation and management.
