摘　　要：应用螯合态多元复合微肥(块根鳞茎型)对不同海拔、不同气候特征的三七开展试验,结果显示:施用该肥后能够提高三七的存苗率,并能够明显提高三七一、二级种苗的比例,600倍液时一、二级种苗比例比对照相应种苗比例提高8.65%,在同一浓度条件下随着海拔的增加,施用效果有逐渐降低的趋势;施药的鲜三七产量都比对照高,最高的浪桥点的600倍液处理比对照增产了1.025 kg,同一试验点内小区的产量随着使用浓度增加而有所增加.An experiment was done to explore the effects of chelated fertilizer （ stalk type） on Panax notoginseng at different altitudes and in different climate. The results showed, that this fertilizer can significantly improve the percentage of seed survivorship, it can significantly increase the percentage of Class-Ⅰ and Class-Ⅱ seeds. When it is diluted by 600%, the percentage of Class Ⅰ and Class-Ⅱ seeds were increases by 8.65%, compared with the contrast group. At the same concentration, the effect tends to be weaker with increasing altitude. The yield of fresh Panax notoginseng was higher than the contrast in any of the condition. With the best result occurred to Langqiao, which was increased by 1. 025 kilogram. Within the same location, the output of fresh Panax notoginseng show positive correlation with the concentration of the fertilizer.
