旱季水肥管理对葡萄柚幼树生长的影响

Effects of water and fertilizer management on growth of young plants in Citrus paradisi

为了给葡萄柚的栽培管理提供理论依据,以促进葡萄柚幼树的生长发育,采用正交试验设计,就不同施肥与灌水处理对云南引进的不同品种葡萄柚幼树生长的影响情况进行了田间试验。结果表明:施肥处理对幼树树高、地径、冠幅及抽梢的影响都很大,灌水次数对其影响次之,而不同品种所受影响程度的差异不大。文中的试验结果与生产实际经验说明,每株幼树施复合肥400 g,每月灌水4次,这对葡萄柚树体生长较为有利。

In order to provide a scientific theory basis for cultivation and management, and to promote growth and development of young plants in Citrus paradise, effects of different water and fertilizer treatments on young plants of different C. paradisi cultivars introduced in Yunnan were researched by a orthogonal ifeld experiment. The results show that the fertilization treatment has a larger effect on plant height, ground diameter, crown width and sprouting, and the irrigation treatment is the second, but there are lesser differences among cultivars. So the treatment of fertilizing 400 g compound fertilizer per plant and irrigating for four times per month is beneifcial to growth of young plants in C. paradisi based on actual production experiment.
