| 摘 要： | 利用田间自然发病条件，以俄罗斯大果沙棘为材料，采用随机区组设计，研究了5种肥料对沙棘干缩病发病率的影响。结果表明：沙棘干缩病在田间的症状有不同表现型，即干枯型、根腐型、枯叶型。试验的2a间，未做任何处理的树木，平均发病率在30％左右。通过沙棘干缩病发病率进行统计分析，发现不同肥料品种对沙棘干缩病的发病率的影响有显著差异，其中钙肥、叶面肥可显著降低沙棘干缩病的发病率。

| Abstract: | Under field conditions,taking Russian seabuckthorn as materials,effect of 5 kinds of fertilizers on incidence of dry shrink of seabuckthron were studied.Result shows that symptoms of dry shrink of seabuckthron have different phenotype: withered and death type,root rot type,litter type.The average incidence of trees without treatment is 30%during the two years' experiments.Statistical analysis on incidence of dry shrink of seabuckthron were conducted.It was found that different fertilizers have significant d... |
