为香根草无土繁殖营养液配置提供科学依据，采用水培方法研究霍格兰氏营养液、改良霍格兰氏营养液和微量元素营养液对香根草生长的影响。结果表明，与对照（蒸馏水）相比，3种营养液均可促进香根草的生长，其中改良霍格兰氏营养液配方培养的香根草株高、根长和茎叶干重最大，分别为36．78 cm、47．74 cm和9．78 g/株。因此，改良霍格兰氏营养液是香根草无土繁殖可选择的配方。
為香根草無土繁殖營養液配置提供科學依據，採用水培方法研究霍格蘭氏營養液、改良霍格蘭氏營養液和微量元素營養液對香根草生長的影響。結果錶明，與對照（蒸餾水）相比，3種營養液均可促進香根草的生長，其中改良霍格蘭氏營養液配方培養的香根草株高、根長和莖葉榦重最大，分彆為36．78 cm、47．74 cm和9．78 g/株。因此，改良霍格蘭氏營養液是香根草無土繁殖可選擇的配方。

To provide a scientific basis for soilless culture of vetiver grass and promote their extension and utilization,three different nutrient solutions were applied to study their effects on growth of vetiver grass.Results:Three nutrient solutions significantly improved the growth of vetiver grass compared with the control tap water.Among them,modified Hoagland solution(Ⅱ)had optimum promoting effect on plant height(36.78 cm),root length(47.74 cm),dry weight of stem and leaf(9.78 g per plant),which were higher than other solution treatments.Modified Hoagland solution(Ⅱ)was the best hydroponics solution for vetiver.
