摘要
在人工栽培条件下研究了不同采挖期和采挖深度对甘草Glycyrrhiza uralensis品质和产量效益的影响。结果表明,在不同年限、不同深度采挖,对人工甘草产量和品质的影响都达极显著水平,从品质、产量和单位面积年均纯收入综合测定,以4年期采挖最为适宜,采挖深度以40 cm为宜。
The effect of harvest time and depth on quality and production efficiency of Glycyrrhiza uralensis was studied under the artificial cultivation conditions,the results showed that the effect of harvest time and depth on licorice quality and production efficiency was highly significant. Analyzed from complex aspects which respectively were quality, production efficiency and net earnings, the result was that 4 year old is the best harvest time and 40 cm is the most convenient harvest denth.
