【摘要】 为了解决有些地方栽植绥李3号不结果或结果很少的问题,根据对各地绥李3号李园结果差异情况调查,发现了有些李园栽植绥李3号品种在配置授粉树技术环节出现了问题;剖析了栽植绥李3号品种在不配置授粉树情况下造成果实绝产、少配置授粉树在李子花期遭遇低温年份造成果实低产、配置授粉树品种不当情况下仍然多年不结果的实质。同时指出了合理配置绥李3号品种授粉树的重要性、配置比例、配置方式和适宜授粉品种。更多还原

【Abstract】 In order to solve the problem of no fruit or fruit rarely of Suili No.3 in some places,based on differences between the results of a plum orchard survey of the local Suili No.3 plum orchard,it found out some problems on configuration of pollination tree in some Suili No.3 plum orchards.The reasons were analyzed,such as never producing fruit without pollination tree configuration,inadequate pollination tree configuration resulting in low yield caused by cold temperatures during flowering stage,improper pollinated tree species led to no fruit for many years.Meanwhile,the importance of rational pollination tree configuration,reasonable allocation ratio,configuration and appropriate pollinated varieties were pointed out.更多还原
