绥李3号倾斜栽培研究

Investigation on Tilt Cultivation Method of Suili No.3 Plum

为了研究绥李3号矮化高产栽培技术,促进该品种更好地推广,进行了绥李3号品种倾斜栽植方式的调查,比较了同龄同一管理条件下绥李3号李树倾斜栽培与直立栽培的树高、前期产量等方面差异。结果表明:绥李3号倾斜45°和60°栽植后比直立栽培的矮化效果显著;二～四年生果实平均产量同比显著提高。建议可继续试验推广,或试验倾斜与直立隔株栽培方式,以达到上下空间合理利用的立体效果和长远期兼顾的合理布局。

In order to study the technology of dwarfing cultivation of Suili No. 3 and promot the extension, the investigation on tree height and early yield of tilt cultivation mode and vertical cultivation of the same age Suili No. 3 under the same management condition was conducted. The results showed that Suili No. 3 tilt at 45 de- grees and 60 degree,after planting, the dwarf effect was remarkable than vertical cultivation, 2~4 years old tree fruit average yield increased significantly. It suggested that the technology could continue to extend and test,or conduct the test of tilt cultivation with vertical isolation cultivation,in order to achieve reasonable layout of cubic effect and long-term consideration by rational use of the upper and lower space.
