苹果低产低效园改造“六优化”措施

摘要:苹果低产低效园改造要因地制宜、因园制宜、因树制宜,做到“六个优化”,即优化栽植密度、优化品种结构、优化树形结构、优化土壤环境、优化投入品管理、优化配套措施等,实现改造升级、提质增效。

Abstract: The transformation of low-yield and low-efficiency apple orchards should be adapted to local conditions, orchard conditions, and tree conditions, so as to achieve “six optimizations”such as optimizing planting density, optimizing cultivar structure, optimizing tree structure, optimizing soil environment, optimizing input management, and optimizing supporting measures to achieve transformation and upgrading, quality and efficiency.

Keywords:apple; low yield and low efficiency orchard; six optimizations; measure

临邑县苹果园大多建于上世纪90年代后期,大部分采用的是乔化砧木,由于建园栽植密度大、群体密度高,栽培模式老、管理技术不配套,果园郁闭度高、病虫害发生严重,造成苹果产量低、品质差、商品果率低、栽植效益差,沦为低产低效园,影响了苹果产业的健康发展。(剩余2589字)
