摘要(Abstract)：

【目的】筛选适合辽西地区苹果园的地面管理模式,明确相关地面管理模式对果园绿肥、土壤和昆虫群落的影响。【方法】针对该地区苹果园气候、生态特点及病虫害综合控制需要,组建清耕、自然生草和人工种草3种果园地面管理模式。绿肥、土壤和昆虫群落等相关指标数据的采集分别采用特定方法、定期调查的方式进行,通过数据对比明确不同模式对相关生态因子的影响。【结果】生草栽培地面管理模式能较好地保持和调蓄土壤水分,有效缓解果园旱情,并且在保持土壤肥力、修复果园生态、提升昆虫丰富程度等方面优于清耕模式。两种生草模式中自然生草在保水、保肥、保温方面各项数据与人工种植三叶草模式相近,但在地面覆盖速度、草株高度和产草量方面具有优势,其杂草种类也经过多年的自然汰选,适应区域气候。【结论】3种地面管理模式中自然生草更适合在辽西苹果园内推广。
