摘要
通过设置对照（只栽桃树不种草）、生草栽培（栽桃树种植百喜草）和常规耕作（油菜-棉花轮作）3种不同处理,测定土壤硬度、土壤有机质、土壤含水量、地表径流量和干土流失量等项目,研究不同栽培措施对土壤生态环境的影响。结果表明：与试验前相比,果园生草处理使土壤硬度降低19.69%,土壤有机质增加23.44%,高出对照40个百分点;生草处理土壤流失量分别是对照、常规耕作处理的1/60、1/88;生草处理土壤的保水能力是对照和常规耕作处理的2-5倍;果园生草栽培对改良果园土壤、保护生态环境有着重要作用。
Three treatments were designed as flowing：control（peach planting without grass,treatment 1）,grass treatment（peach planting with Bahia grass,treatment 2）and conventional tillage treatment（rotation of rape and cotton,treatment 3）.Hardness,organic matter content,water content of soil,runoff and dry soil loss from the surface were tested.The results showed that soil hardness decreased by 19.69% after the grass planting treatment,while soil organic matter increased by 23.44%,which was 40 percentage points higher than that of the control.Erosion loss in grass treatment was 1/60 and 1/88 of the control and the conventional tillage treatment respectively.Soil water holding capacity of the grass treatment was 2-5times that of the control and conventional tillage treatments.Grass cultivation in orchard played an important role in improving soil quality and protecting ecological environment.
