摘要
[目的]研究不同程度短剪对红灯甜樱桃生长及结果的影响.[方法]以长势相对一致、长度和粗度大致相同的红灯甜樱桃为试验材料,设置极重短剪(剪去枝条长度的65%)、重度短剪(剪去枝条的50%)、中度短剪(剪去枝条长度的35%)和轻度短剪(剪去枝条长度的20%)4种不同程度的修剪处理,分析不同处理对红灯甜樱桃的萌芽率、成枝率、新梢生长量、单果重和产量的影响.[结果]通过合理修剪能够提高红灯甜樱桃的萌芽率、成枝率和新梢生长量,修剪程度越重,成枝力和萌芽率都降低,新梢的生长量和单果重有一定程度的提高,产量有一定程度的降低.生产上可根据红灯甜樱桃树体生长情况和市场需求选择适合的短剪方式.[结论]该研究可为红灯甜樱桃科学、合理的修剪提供理论和实践依据.
Abstract
[Objective]To study effects of the short pruning on growth and yield of prunus avium.[Method]Using Cerasus avium (L.)Moench.Hongdeng braches of relatively the same figure of growth,the same length and the same thickness as experimental material,this experiment conducted the following four degrees of trim: experiments-extremly severe short pruning (triming 65% of the whole length),severe short pruning(triming 50% of the whole length),medium short pruning (triming 35% of the whole length) and mild short pruning (triming 20% of the whole length),effects of the short pruning on budding rate,branch rate,shoot growth,per fruit weigh and yield were analyzed.[Result]Through reasonable pruning could increase germination rate,graft rate and new shoots of Cerasus avium (L.)Moench.Hongdeng,the more heavy pruning,branch rate and germination rate decreased,new shoots of growth and per fruit weight rised yield,reduced.Reasonable pruning pattern could be choosed based growth and market demand of Cerasus avium (L.)Moench.Hongdeng.[Conclusion] The research could provide some theoritical and experimental support for the sentific and reasonable trims of Cerasus avium (L.)Moench.Hongdeng.
