造成果树伤根的原因及保护根系的方法

Cause of Root Injury of Fruit Tree and Method of Protecting Root

调研分析了可能造成果树伤根的原因,有气候变化、深翻、施肥、灌水不当、涝灾、修剪过重、不良土壤立地条件影响、根部病害、除草剂、激素应用不当等,提出了避免重茬建园、准备好基肥库、起垄栽培或夏季挖排涝沟、及早深翻扩穴、树盘覆膜或覆草,行间生草、适度深翻、施肥呵护根系、科学四季修剪、预防根部病害、禁用内吸性除草剂等呵护根系的方法及注意问题,以供参考。

The causes of root injury of fruit trees were investigated and analyzed,including climate change,deep plowing,fertilization,improper irrigation,waterlogging,excessive pruning,adverse soil conditions,root diseases,improper application of herbicides and hormones.The methods and problems of protecting roots were put forward,such as avoiding continuous cropping,preparing base fertilizer bank,ridging cultivation or summer drainage ditch,early deep plowing and hole expansion,tree tray mulching or grass mulching,inter-row grass planting,moderate deep plowing,fertilization and root protection,scientific pruning,prevention of root diseases,and prohibition of systemic herbicides,for reference.
