摘　　要：为了明确不同避雨时限对油用牡丹生长特性和产量的影响,本研究以‘凤丹’为研究对象,设置了4个处理:全生长期(1~12月,BY1)避雨、花期(3~4月,BY2)避雨、果期(5~7月,BY3)避雨及不避雨(对照,CK),比较了不同避雨时限对生长指标、花期性状、果期性状和产量的影响。结果表明:避雨栽培模式对‘凤丹’生长及生理指标如茎干直径、株高、新枝长度、叶片光合速率有一定的负面影响,以花期进行避雨影响最大;对‘凤丹’花径大小也有不利影响,但可以明显提高单株开花数量,其中以花期避雨效果最明显;花期和果期避雨能明显提高植株的坐果率,分别提高4.9%和7.3%;3种避雨栽培时限均能有效提高‘凤丹’的果实产量,明显降低植株的病虫害发生率。研究结果表明,避雨栽培能够有效减轻梅雨季节对油用牡丹的不利影响,减少病虫害的发生,有效提高油用牡丹的产量。In order to clarify the effects of different rainproof times on the growth characteritics and yield of oil peony,'Fengdan'was taken as the research object in this study.Four treatments were set up:whole life long-term(January to December)rainproof,flowering(March to April)rainproof,fruiting(May to July)rainproof and no rainproof(control).The effects of different rainproof times on growth indexes,flowering characters,fruiting characters and yield were compared.The results showed that:the rainproof cultivation model had a certain negative effect on the growth and physiological indexes of'Fengdan',such as stem diameter,plant height,new branch length and leaf photosynthetic rate.The greatest effect existed in the rainproof cultivation at flowering stage.It also had an adverse effect on the flower diameter of'Fengdan',but it could significantly increase the flower numbers of single plant,especially at the flowering stage.Rainproof cultivation at flowering and fruiting stage can remarkably improve the fruit setting rate,by 4.9%and 7.3%respectively.The three time limits of rainproof cultivation can effectively improve the fruit yield of'Fengdan'and significantly reduce the incidence of plant diseases and pests.The results showed that rain shelter cultivation could effectively reduce the adverse effects of plum rain season on oil peony,reduce the incidence of plant diseases,and subsequently improve the yield of oil peony'Fengdan'.
