摘　　要：在云南省瑞丽市柠檬种植基地,选择施用不同剂量(66.7、100.0、133.0 g/株)的绿吧"ZebaTM"淀粉土壤改良保水剂对柠檬园土壤进行保水研究。结果表明:不同剂量的保水剂对柠檬园土壤温度、湿度、树体生长产生一定的影响;柠檬树体株高、冠幅、着果率及产量明显高于对照,施用保水剂的3个处理,柠檬单位面积产量比对照(CK)高40.0%、6.7%、80.0%(p<0.05),保水剂的使用有利于坐果;土壤温度、湿度与树体的生长关系呈极显著相关;冠幅指数、抽梢次数、总梢数、花蕾数、幼果数量与产量呈显著相关。A field experiment was carried out to study effects of ＂ZebaTM＂ water-retaining agent with different dosages（66.7,100.0 and 133.0 g/plant） on soil properties in lemon orchard in Ruili City of Yunnan province.The results showed that different dosages of water-retaining agent all affected soil temperature,soil moisture and growth of lemon in lemon orchard to a certain extent;the tree height,crown width,fruit setting rate and yield of lemon tree with application of water-retaining agents were significantly higher than that of control;in all three treatments with application of water-retaining agents,yield per unit area of lemon increased by 40.0%（66.7 g/plant）,6.7%（100.0 g/plant） and 80.0%（133 g/plant,p0.05）;the application of water-retaining agent was propitious to fruit setting;there was a extremely significant correlation between soil temperature,soil humidity and growth of lemon tree;there was a significant correlation between crown index,shooting numbers,total branch number,number of flower-bud,number of young fruit and yield.
