为探明甜樱桃不同品种特性并有针对性的制定修剪方案,采用系统聚类分析法,研究山西省种植的14个甜樱桃品种的枝类组成。研究结果表明,供研究的14个甜樱桃品种,可以区分为以‘红玛瑙’和‘雷尼尔’为代表的2种类型;不同类型之间的坐果率、成枝率、中果枝比例、短果枝比例和单株产量差异均达到显著水平。为提高‘雷尼尔’品种类型的产量,树体整形修剪管理的重点,在于提高坐果率、短果枝比例,并适当控制中、长果枝比例。
In order to find out the characteristics of sweet cherry varieties and to develop the pruning schemes, systematic cluster analysis was used to study the branch composition of 14 sweet cherry varieties planted in Shanxi Province. The results showed that the 14 varieties of sweet cherry for research can be divided into two types represented by ’Onyx’ and ’Rainier’; the fruit set rate, branch rate, middle branch ratio, The ratio of short fruit branches and the yield per plant reached the significant level. In order to increase the yield of ’Rainier’ varieties, the key point of tree trim pruning management is to improve the fruit setting rate and the ratio of short fruit branches and to properly control the ratio of medium and long fruit branches.
