为明确烟台地区“美早”甜樱桃优质高效生产的最佳树体结构参数，对福山区台上村、南厚滋沟村和莱山区界牌村3个地点丰产稳产甜樱桃试验园10～13年生的树体结构进行了比较研究。结果表明：3个试验园666．7m2产量分别为1420、1824、1188 kg，单果重分别为11．9、9．1、10．6 g，售价分别为44．0、28．0、35．4元／kg，666．7m2经济收入分别为6．24万、5．11万、4．20万元；台上村甜樱桃园产量适中、单果重大、果实品质好、经济收入高，其树体结构适宜，结构参数为：小冠疏层形，干高35 cm、干周62 cm、树高3．60 m、层间距50～60 cm、主枝间距2～10 cm；13个主枝，主枝长1．85～2．25 m，基角、腰角、梢角分别为83～84°、67～80°、35～50°；树势中庸，外围新梢长度为23．1 cm；666．7m2结果枝104550个，长果枝、中果枝、短果枝、花束状果枝分别占9．7％、3．5％、5．6％、81．1％，优质花束状果枝64403个，占61．6％。%To definite the best tree structure parameters for fine -quality and high -efficiency production in Yantai Area,the tree structures of 1 0 ~1 3 years old Tieton sweet cherry from 3 high -and stable -yield orchards were compared and researched,which located in Taishang Village,Nanhouzigou Village of Fushan District and Jiepai Village of Laishan District.The results showed that the yield per 666.7m2 of 3 orchards were 1 420,1 824 kg and 1 1 88 kg respectively;the single fruit weight were 1 1 .9,9.1 g and 1 0.6 g respec-tively;the selling price were 44.0,28.0 yuan /kg and 35.4 yuan /kg respectively;the income per 666.7m2 were 62 400,51 1 00 yuan and 42 000 yuan respectively.The yield,single fruit weight,fruit quality and in-come of sweet cherry orchard in Taishang Village were all the best.Its tree structure was suitable with small and sparse canopy shape.The parameters were as follows:trunk height as 35 cm,trunk girth as 62 cm,tree height as 3.60 m,interlayer spacing as 50 ~60 cm,main branch spacing as 2 ~1 0 cm.There were 1 3 main branches with length of 1 .85 ~2.25 m,basal angle,waist angle and tip angle of 83 ~84°,67 ~80°and 35 ~50°respectively.The tree vigor was middle with length of outside shoot of 23.1 cm.There were 1 04 550 bear-ing branches per 666.7m2 ,and the rates of long fruit branches,middle fruit branches,short fruit branches and cluster fruit branches were 9.7%,3.5%,5.6% and 81 .1 % respectively.There were 64 403 high -quality cluster fruit branches,which accounted for 61 .6%.
