试验测定结果初步显示,在云南省营造蓝桉(Eucalyptus globulus)速生丰产林时,除施有机垃圾肥做底肥外,应重视氮、磷、钾肥的合理配合施用,其中磷肥对蓝按幼林生长的促进作用最大,而且对病害的发生及为害程度有控制作用,其为害程度对照区比处理区高2.3倍。方差分析显示本试验设计的氮、磷、钾施肥配比,在控制病害方面是可行的。回归测定病害的严重程度随树高增加而减小。经对蓝桉施肥试验不同处理病害调查分析,建议采用试验方案中的第10、9、2处理中的任意一种处理组合,可明显减轻病害发生。
The preliminary test results show that, in order to create fast-growing and high-yield forests of Eucalyptus globulus in Yunnan Province, in addition to the application of organic garbage to make base fertilizer, nitrogen, phosphorus and potassium fertilizers should be paid reasonable attention. Promote the role of the greatest, but also the incidence of disease and the degree of control have a controlling role, the extent of damage control area 2.3 times higher than the treatment area. Analysis of variance showed that the ratio of nitrogen, phosphorus and potassium fertilizers designed in this experiment was feasible in controlling diseases. Regression to determine the severity of the disease decreases with increasing height. Through the investigation on different treatment diseases of Eucalyptus globulus, it is suggested that any one of the 10,9,2 treatments in the experimental plan should be used to reduce the occurrence of diseases.
