摘要
造成果树早期落叶的主要原因有生理性落叶、病理性落叶及害虫性落叶。提出了预防果树早期落叶的方法,包括:园地选择、避免连作、选用抗病树种及品种、建设防护林等科学建园方法,通过加强土肥水管理,合理整形修剪、疏花疏果等栽培措施提高抗病能力,采取清除病原及虫源,适时用药等方法有效地预防早期落叶。
The causes of early defoliation of fruit trees were analyzed,including physiological defoliation,pathological and pest defoliation.The scientific construction of orchards such as plot selection,avoiding continuous cropping,selection of disease-resistant tree species and varieties,and construction of shelter forest were put forward.Strengthen the management of soil,fertilizer and water,reasonable pruning,improve the cultivation of healthy trees such as flower and fruit thinning,and improve the disease resistance;the methods of eliminating pathogens,insect sources,and timely drug prevention and control were adopted to prevent early defoliation.
