摘要
对尾巨桉组培苗移植到容器袋时所用的基质、基肥品种及苗期追肥配方和浓度等进行全面的试验研究。结果表明:本地不同地点土质对桉树组培苗移植的成活率影响不明显;而使用不同的基肥对移植的成活率有很大的影响,以施用钙镁磷肥3kg·m-3的成活率最高,追肥是决定壮苗的关键,配方A3即浓度为300×10-6的磷酸二铵和硫酸钾的复合肥是尾巨桉移植苗追肥的最佳配方。
The different substrates and base fertilizers in containers in which the tissue culture seedlings of Eucalyptus urophylla×E.grandis were transplanted and the formulae and concentrations of top dressing in seedling stage were studied.The results showed that:The quality of soil taken from different sites did not cause obvious difference among survival rates of tissue culture seedlings of E.urophylla×E.grandis when they were transplanted.However,the base fertilizer caused great difference among them,and the survival rate was the highest when the fused calciummagnesium phosphate (3kg·m3) was used as base fertilization.The top dressing was the key technique for good seedlings,and A3 was the best formula for top dressing that contained 300×103 ammonium primary phosphate and potassium sulfate.
