摘　　要：为解决密植枣园易造成果园过度郁闭、结果能力下降、果实品质较差等问题,以新疆北疆地区主栽品种垦鲜枣1号为试材,对矮密栽培模式下红枣进行摘心试验。结果表明:不同摘心处理对枣头长度(F=9.218)、二次枝长度(F=3.755)以及Pn、E、C、InTCO2影响差异极显著,不同处理间枣吊长度(F=0.647)差异不显著,枣头粗度、枣头节间长度等指标存在显著差异。通过对不同摘心处理生物量调查与光合特征参数的分析,得出矮化密植枣园优化的摘心处理技术,为矮化密植枣园的树体调控提供理论依据。In order to solve the problems of excessive closed, fruiting capacity sharply droped and poor quality in densely planting orchards, the pinching experiment was conducted by using main cuhivars kenxianzaol as materials in the cold north xinjiang. The results showed that length of extension shoot（F=9.218） and length of secondary shoot（F=3.755） and Pn,E,C,InTC02 shows very significant among various treatments.Difference of lipase length of bearing shoot （F=0.647）was insignificant. Ticknessof extension shoot, length of internodc etc were significant differences among various treatments. Based on analysing on the topping characteristics of growth, development and photosynthetic characteristic parameters of various treatments, we sums up optimization technical measures in the short-stalked and close-planting jujube yards, and provide theoretical basis for tree size control of the short-stalked and close-planting jujube yards.
