罗马甘菊幼苗生长的研究

目的]加快罗马甘菊幼苗生长，提高幼苗质量。方法]研究不同激素（IBA、NAA、IBA＋NAA）、激素体积比例（1：1、1：2、2：1）、激素浓度（30、45、60mg／L）对罗马甘菊幼苗生长影响，并且记录不同时段植株增长情况。结果]IBA与NAA以l：2（体积比）混合，浓度为45mg／L的处理对罗马甘菊幼苗生长影响显著；幼苗缓苗期5d，快速生长期在移栽后15-25d。结论]IBA与NAA以1：2（体积比）混合，浓度为45mg／L时可以促进罗马甘菊幼苗生长生根；在移栽后15～25d可加强幼苗肥水供应。

Study on the Growing of Roman Chamomile Seeding

Objective] The study aimed to provide the reference for the growth and quality of the Roman chamomile seedling.Method] The effect of the different hormone(IBA,NAA,IBA+NAA),the different proportion(1∶1,1∶2,2∶1),the different concentrations(30,45,60 mg/L) on the growth of Roman chamomile seedlings was researched;and recorded the adding conditions in different period.Result] The treatment as IBA+NAA mixing with volume ratio as 1∶2,and the concentrations is 45 mg/L to the seedlings of Roman chamomile can reach significant levels;the slowly growing period of the seeding is 5 d,rapidly growing period after transplanting is from 15 d to 25 d.The disposal can play its role after 5 d,and the seedling's rapid growth period is in the 15 d to 25 d.Conclusion] The treatment as IBA+NAA,mixing with volume ratio as 1∶2,and the concentrations is 45 mg/L can advance the growth and rooting of the Roman chamomile;fertilizer water irrigation should be enhanced in 15 d to 25 d.
