摘要：

摘要：通过对黄芩采用室外盆栽控水，测定不同生长发育阶段黄芩的耗水量、地上、地下部分的质量变化以及产量和有效成分含量。试验设三个处理，分别为土壤相对含水量的30%，50%，80%。结果表明黄芩的耗水量在开花前营养生长阶段耗水量最大；土壤相对含水量30%和80%的处理都不利于黄芩的生长发育；土壤相对含水量50%的处理黄芩产量最高，并且有效成分含量达到13.6%，与其他处理差异显著。

Abstract:

Abstract: By measuring water consumption, weight changes of shoot and root, yield, component ingredients in different phase of growth and development of Scutellaria baicalensis Georgi through pot planting and weighting.The water supply experiment was done at 3 different soil water gradients of 30%,50%,80%,respectively.The results indicitaed that the water consumption was largest at vegetative stage before flowering stage of Scutellaria baicalensis Georgi. The water gradients of 30% and80% could produce unfavorable effects on the growth and development of Scutellaria baicalensis Georgi. The yield of root and the contents of effective component of Scutellaria baicalensis Georgi was higher relatively than others,which had significant difference at soil water gradients of 50%. the contents of effective component of Scutellaria baicalensis Georgi was 13.6%。
