摘要
丹桂在幼苗期生长速度较慢,育苗期较长,为了缩短丹桂育苗期,提高成活率,选配了“绿精灵”1号和“绿精灵”2号营养剂,并对其在丹桂育苗中的应用效果进行了研究。结果表明:营养剂处理可以促进丹桂幼苗生长,提高幼苗生长势,从而加快幼苗出圃速度,缩短育苗周期。“绿精灵”1号和“绿精灵”2号处理的幼苗长势均比对照好,以“绿精灵”1号增加根长、茎粗和株高等的效果最为明显。
The growth rate of sweet olive(Osmanthus fragrans)seedlings is slow and the seedling period is long,which increases the cost of the seedling users.In order to shorten the seedling period,reduce the cost and increase seedling survival rate,the author prepared two kinds of plant nutrients,“Green Spirit No.1”and“Green Spirit No.2”,to study their application effects on seedling raising of sweet olive.The research results showed that spraying plant nutrient solution could promote the growth of sweet olive seedlings,improve the growth potential of seedlings,and shorten the seedling period.The seedling growth of the two treatments was better than that of the control,and the effect of“Green Spirit No.1”on increasing root length,stem diameter and plant height was obvious.
