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。
Eucalyptus is one of the widely cultivated species of fast-growing timber in southern China. Although there is a successful afforestation experience, the research on the nutritional requirements of eucalyptus is still scarce. Therefore, the widely planted eucalyptus seedling mineral nutrition research, to cultivate strong seedlings and young fertilizers have a certain significance. In this experiment, the hydroponics was used to explore the nutritional formula suitable for the growth of eucalyptus seedlings. On this basis, the effects of solution concentration and pH value on the growth of eucalyptus seedlings were tested to select the best nutrition solution, suitable concentration and pH value , Laying the foundation for further study of eucalyptus mineral nutrition.
