摘　　要：果园生草作为一项生态环保型的果园管理技术,已在我国许多地区得到了推广应用。本研究通过对陇东典型旱塬苹果种植区庆阳市172户农户的问卷调查,分析了果园生草现状及农户生草意愿;并运用Logistic回归模型对当地农户实施果园生草意愿的影响因素进行了定量分析。结果表明,目前陇东旱塬果园生草的应用率为23.8%,36%的农户有果园生草的意愿。在影响果园生草意愿的因素中,果园类型(P<0.01)、农户对果园生草技术的了解程度(P<0.01)、能否及时获取技术信息(P<0.01)和户主文化程度(P<0.05)对农户的果园生草意愿呈显著影响。Planting forage grass in orchards has been widely applied in many areas of China as it is an environmentally friendly orchard management technique.Based on survey data from 172 orchardists in Qingyang of Gansu Province,this study analysed growing forage grass in orchards and the willingness of orchardists to grow grass.We used the logistic regression model to quantify the contribution of different factors related to the willingness of the orchardists.The results showed that 23.8% of the orchardists have planted forage grass and 36%plan on planting forage grass;the majority are unaware of the practice.The choice of orchard types（P〈0.01）,orchardists’ understanding of grass mulching（P〈0.01）,timely information（P〈0.01）and householders’ educational level（P〈0.05）showed significant impacts on the their willingness.
