摘　　要：通过武威低产枣园进行补植加密、高接换优及合理修剪等方面的试验研究,结果表明：低产枣园增施有机肥,应选择每667m^2施优质腐熟羊粪2m^3为佳;花前、果实膨大期喷尿素液、磷酸二氢钾为最佳;改大冠稀植为矮化密植,每667m^2栽红枣达110-220株,可增加单位面积株数,提高产量;实施夏季修剪、喷水、喷微肥、喷调节剂等技术和低产旺树开甲技术等措施,可使红枣坐果率提高29.3%。Experiments of reinforcement planting, graft in top and reasonable pruning were conducted. Result shows that 2 m^3 high-quality decomposed sheep manure should be applied in low-yielding Ziziphus jujuba orchard per 667 m^2 ;spraying urea solution, potassium dihydrogen phosphate is the optimal in fruit enlargement period;changing big crown with sparse dense to dwarfed dense planting, Ziziphus jujuba were planted 110-220 trees every 667 m^2 ;the number of units per hectare can be increased; production were increased. The fruit setting percentage can be in- creased by 29. 3% by implementation technologies （summer pruning, spraying water, spraying micro-fertilizer, spraying regulator and measures （girdling of low-yielding ＆ vigorous trees）.
