摘要: 为提高中药材黄芩的产量以及规范化生产,文章研究大棚内培育黄芩在不同施肥量与密度条件下对根系形态指标及根部干、鲜重变化的影响。试验采用随机取样,在黄芩出苗后45,70,95,120,145 d分别采集黄芩的地下部分,测定主根长,根表面积,根体积,主根直径及根部干、鲜重。结果表明:黄芩药用部位在F2(磷酸二铵330.00 kg/hm2+尿素64.65 kg/hm2)处理下各根系形态指标优于其他处理,且生长速度较其他处理更快,同时密度的增加影响黄芩根系的生长。

关键词: 黄芩, 根系形态指标, 施肥量, 密度

Abstract: In order to improve the yield and standardized production of Scutellaria baicalensis,the effects of different fertilization levels and densities on root morphological indexes and the dry and fresh weights of Scutellaria baicalensis seedlings cultured in greenhouse were studied.The underground parts of Scutellaria baicalensis were collected at 45,70,95,120 and 145 days after emergence.The length,surface area,volume,diameter and dry and fresh weight of the main roots were measured.Suitable amounts of fertilizer can promote root growth and speed up the growth of Scutellaria baicalensis.Under the experimental conditions,the morphological indexes of the medicinal parts of Scutellaria baicalensis under the F2 (330.00 kg/hm2 phosphate+64.65 kg/hm2 urea) treatment were better than those of other treatments,and the growth rate was faster than with the other treatments.The increase of density affected the root growth of Scutellaria baicalensis.

Key words: Scutellaria baicalensis, Morphological indexes, Fertilization, Density
