德江天麻种植基地土壤养分含量分析及评价

摘要

对德江天麻种植基地土壤pH、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 pH value,nutrient content in Dejiang cultivation base of Gastrodia elata Blume. The results showed that soil was in acidic environment and it met the require-ments 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-avail-able potassium. And the soil fertility was in the fourth level. Sometimes it maybe have an effect of nor-mal growth. It recommended many ways in planting,such as reasonable application-specific fertiliz-er,the amount of added fertilizer,rational application of microbial fertilizers,scientific and rational planning of planting,cultivation and management focus.
