摘要
通过试验研究采用不同种类的根外施肥、不同根外施肥浓度及不同喷施根外追肥间隔时间对不同无性系的尾赤桉圃地组培苗生长量的影响。结果表明:尾赤桉M1无性系+高钾型高乐+500倍液+每间隔5d喷施一次叶面肥最好,平均苗高达15.13cm,平均地径达3.71mm。
Effects of fertilization on the growth of E. urophylla × E. canudldensis tissue culture seedling in nursery were studied by different fertilization modes, fertilization levels and interval time of fertilization. The results were showed： when the high potassium type fertilizer was applied to the seedlings at 500 time fertilization level the fertilization were every five days by spraying leaf fertilizer, the M1 clone seedlings of E. urophylla × E. camaldulensis had a good fertilization effect, theirs average seedling height was 15.13 cm, and average ground diameter was 3.71 mm.
