摘　　要：以"尤力克"柠檬为材料,研究了全疏果、1/2疏果、1/3疏果和不疏果(对照)对1年生幼树柠檬生长及其产量的影响。结果表明:疏果对柠檬树体冠径、冠形指数、干径与柠檬枝稍数量的影响不大,柠檬分枝级数量有所增加。疏果促进产量的提高,疏果1/2和疏果1/3单株挂果量比对照增加65.0%,17.5%,单株产量比对照增加52.9%,11.8%,666.7 m2产量比对照增加52.8%,8.2%;全疏果的单株挂果量、单株产量与亩产量分别比对照降低38.8%,41.2%,44.6%。The lemon [ Citrus limon （L.） Burm. F. , Eureka] cultivar ＇Eureka＇ was used to study the effects of four levels including whole, 1/3, 1/2 fruit-thinning and non-thinning （CK） on the tree growth and yieldsl The result showed that the effects of crown diameter, crown-shaped index, trunk diameter and branches number were not significant differences （ P 〉 0. 05 ）. But step branch number was increased compared with CK. The fruit number per plant of 1/2 and 1/3 fruit-thinning treatments were increased by 65.0% and 17.5% , the yield per plant were increased by 52. 9% and 11.8% , the yield per 666.7m2 were increased by 52. 8% and 8.2% , compared with control. In addition, compared with CK, the fruit number per plant of fruit-thinning all treatment was decreased by 38.3%, the yield per plant was decreased by 41.2%, the yield per 666.7m2 was decreased by 44.6%.
