摘要
桉树作为我国主要的人工用材林,为我国各方面行业提供了大量树木资源。而提升桉树成长水平,增加桉树经济效益,是当前桉树培育方面的主要问题。通过对不同施肥情况对桉树根系延伸的促进作用及不同施肥量对桉树生长影响进行了研究,结果表明:不同肥料种类对桉树根系生长有着不同的影响,磷肥主要影响桉树幼苗的垂直延伸,桉树专用肥主要影响桉树根系的水平延伸和扎根能力,氮肥主要影响桉树根系的根尖数量。而肥料施用量对桉树的生长情况有明显的促进作用。经过1年的生长数据对比,胸径增长了2.3 cm,树高增高5.4 m,平均胸径和树高均高于同一时期使用其他肥料种植的桉树。在实际培育过程中,可以分阶段、分环境给予桉树不同的肥料配比,以达到最优的生长效果,同时合理增加施肥量,促进桉树生长,提升桉树经济效益。
Eucalyptus,as the main artificial forest,provides a large number of tree resources for every aspect of our industry.It is the main problem of Eucalyptus cultivation to improve the growth level and increase the economic benefit of Eucalyptus.In this paper,the promotion effect of different fertilization conditions on the root elongation of Eucalyptus and the effect of different fertilization rates on the growth of eucalyptus were studied.The results showed that different fertilizer types had different effects on the root characters of Eucalyptus,and P fertilizer mainly affected the vertical extension of Eucalyptus seedlings.Eucalyptus special fertilizer mainly affected the horizontal extension and rooting ability of Eucalyptus roots.Nitrogen fertilizer mainly affected the number of root tips of Eucalyptus.However,the application rate of fertilizer significantly promoted the growth of Eucalyptus.In the actual cultivation process,different fertilizer ratio can be given to Eucalyptus in different stages and different environments to achieve the optimal growth effect.At the same time,the amount of fertilizer can be reasonably increased to promote the growth of Eucalyptus and improve the economic benefits of Eucalyptus.
