针对山地苹果园大多立地条件较差,土壤贫瘠、缺水少肥,再加上管理粗放,导致产量不稳、品质下降、效益低下的现状,我们在河北省承德市宽城县化皮溜子乡西岔沟村、三家村、化皮溜子村瘠薄山地的长富2苹果园、围场县四道沟乡二道沟村瘠旱山地的金红苹果园进行了4年试验(试验园面积17.9 hm2),总结出了瘠旱山地果园反坡集流贮肥技术。该项技术已示范推广146.7 hm2,每667 m2投入465元,10~20 In view of the poor condition of most apple orchards in mountainous areas, the poor soil conditions, the lack of water and less fertilizer, coupled with extensive management, leading to unstable yields, declining quality and low returns, we are located in the suburbs of Kaohsiung City, Hebei Province, Changchai 2 apple orchards in Xichacha Village, Sijia Village and barren mountain of Huapizizi Village and Jinhong Apple Orchard in barren mountainous area of ​​Erdaogou Village, Sidaogou Village, Weichang County, were tested for 4 years (test garden area 17.9 hm 2 ), Summed up the barren mountain orchard reverse slope flow storage technology. The technology has been demonstrated to promote 146.7 hm2, invested 465 yuan per 667 m2, 10 to 20
