摘　　要：采用不同N、K配比营养液与GA3协同处理韶羞幼苗,分析其株高、茎粗、冠幅、叶下高、叶数、叶长、叶宽、芽数、单位长度枝梢上的叶数、根数和根长以及根冠比的变化。结果表明:低K高N的营养液配方对植物的株高、叶宽、叶数、叶下高均有促进作用;低N高K营养液配方能够促进叶片伸长,促进根系生长;GA3处理对韶羞株高、茎粗的生长有促进作用,对根系生长有抑制作用。结合韶羞幼苗株型结构综合评价结果来看,C1处理对韶羞幼苗株型结构的影响效果最好。Different N,K Ratio Nutrient Solution and GA3 were used to treat Aeonium'Blushing Beauty'seedlings,the changes of plant height,stem diameter,crown width,leaf height,leaf number,leaf length,leaf width,bud number,leaf number per unit length,root number,root length and ratio of root to shoot were analyzed.The results showed that low K and high N nutrient solution could promote plant height,leaf width,leaf number and lower leaf height,and low N and high N nutrient solution could promote leaf elongation and root growth.GA3 treatment can promote the height and stem diameter of Aeonium'Blushing Beauty'and inhibit the growth of root system.The effects of C1 treatment on the plant type of Aeonium'Blushing Beauty'seedlings were the best.
