本课题的研究工作包括：对国外相关资料的调研分析；对已建沙漠地区公路进行调查、观测了十余条线路，近百段路段，以‘ 210国道包头至东胜一级公路’ 、 ‘内蒙阿拉善盟s307尚德至孟根段’为主要调查对象；风沙流路基高度的关系、风洞试验；对调查路段及依托工程调查、观测结果统计研究；不同高度下路基稳定性分析；路基经济性分析；按照沙丘类型及公路等级提出路基合理高度推荐值。 - Twenty one adventitious buds from 30 root segment cultures were obtained after subculturing on medium lacking growth regulator for 90 days . the effects of hormones 6 - ba and naa on the adventitious bud differentiation were investigated and optimized . the results were showed that 6 - ba had significant effect on bud differentiation and the optimized medium for adventitious bud differentiation was ms + l . 0mg / l naa + 0 . 5mg / l 6 - ba . there were 67 adventitious buds occurred from average 30 hairy root segment cultures
90d后统计不定芽数量，平均每30个根段培养物上可获得21个不定芽；添加0 . 5mg 16 - ba能显著地促进毛状根不定芽的分化，配合使用6 - ba和naa对毛状根不定芽的分化最为有效( ms + 1 . 0mg lnaa + 0 . 5mg l6 - ba ) ， 90d后统计，平均每30个根段培养物上可获得67个不定芽。
