Effects of Nutrient Solutions on the Growth Status of Tea Plants under Aeroponics Cultivation

[目的]气雾栽培营养液对茶树生长状况的影响。[方法]采用塔式气雾栽培方式,研究了4种营养液配方处理对3个茶树品种(中黄1号、景白2号和黄金芽)成活率、全株鲜重、株高、主根长度、根数、茎干长度和着叶数的影响。[结果]气雾栽培营养液配方处理的茶树苗成活率均在95%以上,其中T3处理的成活率最高,其全株鲜重、株高、主根长度、根数、茎干长度和着叶数等性状与其他处理有显著差异。[结论]该研究为茶树扦插育苗技术的改良和新技术的应用提供理论依据。

[Objective]To research the effects of nutrient solutions on the growth status of tea plants under aeroponics cultivation.[Method]Tower-type aerosol cultivation method was adopted to research the effects of four nutrient solution treatments on the survival rate,whole-plant fresh weight,plant height,the length of the main root,root number,the length of the stem,and the leaf number of three tea plants(Zhonghuang No.1,Jingbai No.2 and Golden Sprout).[Result]The survival rates of tea seedlings with aeroponics method treatments were all more than 95%.Among them,T3 treatment showed the highest survival rate,and its whole-plant fresh weight,plant height,the length of the main root,root number,stem length,and leaf number of tea plants were greater than those of other treatments.[Conclusion]This research provided theoretical basis for the improvement of cutting and seedling technology of tea plants and the application of new technologies.
