摘要
桉树(Eucalyptus)是我国南方广泛栽培的速生用材树种之一,虽有一套成功的造林经验,但对桉树的营养需求研究尚少。所以,对广为种植的桉树进行苗期矿质营养研究,对培育壮苗和幼林的合理施肥都有一定的意义。本试验选用水培法探讨适于桉苗生长的营养配方,在此基础上进行溶液浓度及pH值对桉苗生长影响的试验,以选出最佳的营养液配方,适宜的浓度和pH值,为进一步研究桉树矿质营养打下基础。
This paper deals with the selection of suitable form, concentration and pH value of nutrient solution for the water culture of E. cam-aldulensis and E. 12ABL seedlings. The results can be summarized asfollows:1.Among the four nutrient solution forms which are of representatives i. e. Hoagland, Plonisnicofe ,Cronip and Walker et al. nutrient solution forms, Hoagland one is the best for the growth of the two species seedlings.2.The standard concentration of Hoagland nutrient solution is more suitable for the growth of the seedling than the others.3.The range of pH value which is suitable for the seedling grow th is 4.0~6.0 but 5.0 is the best.
