【摘要】 为比较青枣单种和青枣行间种植2种牧草的效益,在种植当年的青枣园行间,种植黑麦草和紫花苜蓿,设置青枣单种、青枣+黑麦草、青枣+紫花苜蓿、青枣+黑麦草/紫花苜蓿4个种植模式,观测研究4个种植模式单位面积的经济效益。结果表明:青枣+紫花苜蓿和青枣+紫花苜蓿/黑麦草种植模式下,牧草产量和经济效益显著高于青枣+黑麦草种植模式(p<0.05);青枣+紫花苜蓿、青枣+紫花苜蓿/黑麦草种植模式牧草产量分别比青枣+黑麦草种植模式高8 373.60、9 280.55 kg/hm~2,分别增加效益20 934.00、23 201.50元/hm~2,其中效益增幅为93.73%和103.88%。青枣+黑麦草、青枣+紫花苜蓿、青枣+紫花苜蓿/黑麦草的效益分别比青枣单种高22 335.25、43 269.25和45 536.75元/hm~2,且每公顷可节约80～94个人工,节约除杂费8 000～9 400元。本研究为区域果园间种牧草提供技术支撑和理论依据。更多还原

【Abstract】 Lolium perenne（LP） and Medicago sativa（MS） were planted between rows in the green jujube（Zizyphus mauritiana, ZM） orchard established in the first year. Four planting patterns were arranged,including ZM monoculture, ZM + LP, ZM + MS, ZM + LP/MS. The per unit area benefits of the four planting patterns were calculated and analyzed. The analysis showed that the patterns ZM + MS and ZM +MS/LP gave significantly higher forage yield and economic benefits（p<0.05） than the patterns ZM + ZP.The pattern ZM + MS,ZM + MS/LP produced higher forage yield than the patterns ZM + LP, increasing by8 373.60 and 9 280.55 kg·ha-1, respectively,the increased benefit is 20 934.00 and 23 201.50 yuan·hm^-2,and the benefit growth rate was 93.73% and 103.88%.Compared with the monoculture of ZM, the patterns ZM + LP, ZM + MS and ZM + MS/LP increased their benefits per hectare by RMB 22 335.25、43 269.25 and 45 536.75 yuan, respectively, and saved labor by 80-94 working days per ha and cost of weeding 8 000-9 400 yuan per hectare. This experiment might provide technical support and theoretical basis for interplanting forages in regional orchards.更多还原
