摘要
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。
By investigating and analyzing the p H value,nutrient content in Dejiang cultivation base of Gastrodia elata Blume. The results showed that soil was in acidic environment and it met the requirements of planting. The concentration was more abundant and soil fertility with the second level,such as soil organic matter,total nitrogen,and available nitrogen. It offered natural advantages for high-quality,high yield of Gastrodia elata Blume in Dejiang. It was lack of slowly available and fast- available potassium. And the soil fertility was in the fourth level. Sometimes it maybe have an effect of normal growth. It recommended many ways in planting,such as reasonable application- specific fertilizer,the amount of added fertilizer,rational application of microbial fertilizers,scientific and rational planning of planting,cultivation and management focus.
