摘　　要：为了探索出掌叶覆盆子每株主枝上的侧枝留养最佳个数,以摘心后高度在150 cm左右和根径粗1.8~2 cm的主枝为试材,于2020年开始在每个主枝上留养不同侧枝个数试验,用2年试验的平均数据,比较不同侧枝数对主枝冠径、单果重量、单株产果数和单株产量变化的指标进行分析,结果表明:主枝平均冠径每个主枝留养侧枝9个(134.37 cm)和7个(134.00 cm)、平均单果重每个主枝留养侧枝7个(4.09 g)和8个(4.03 g)、平均株产果数量每个主枝留养侧枝9个(199.47颗)和10个(189.43颗)、平均株产量每个主枝留养侧枝9个(670.76 g)和8个(667.51g),表现最好;6种处理之间的冠径差异不显著,但单果重、株产果数和株产量均达到极显著差异。为此,在掌叶覆盆子栽培修剪时,每个主枝留养侧枝应控制在9个左右。In order to explore the optimal number of side branches on each main branch of Rubus chingii,the main branches with a height of about 150 cm and a root diameter of 1.8-2 cm were used as test materials,and the experiment of different number of side branches on each main branch was started in 2020.The average data of 2 a experiment were used.The indexes of main branch crown diameter,fruit weight per plant,fruit yield per plant and yield per plant were analyzed by comparing different branch numbers.The results showed that:The average crown diameter of each main branch was 9(134.37 cm)and 7(134.00 cm),the average fruit weight was 7(4.09 g)and 8(4.03 g),the average fruit yield was 9(199.47 a)and 10(189.43 a),and the average plant yield was each The main branch was maintained with 9 branches(670.76 g)and 8 branches(667.51 g).There was no significant difference in crown diameter among the six treatments,but there were significant differences in fruit weight,fruit number and yield.Therefore,in the cultivation and pruning of palm leaf raspberry,each main branch should be kept and raised in about 9 branches.
