摘　　要：在塑料大棚栽培条件下,采用三因素三水平的正交设计L9(34),研究定植密度、整枝方式、授粉次数对番茄一代杂种种子产量和质量的影响,筛选番茄大棚制种技术的最优组合。结果表明:3个因素对制种效果影响的大小为定植密度>授粉次数>整枝方式;3340株.(667m2)-1、双干整枝、授粉3次为最佳组合,番茄种子的产量和质量最高。Effects of plant density, pruning way and pollination times on the yields and quality of F1 hybrid seeds were studied by orthogonal experiment design of L9 （3^4） , so as to find the optimal portfolio of tomato （Lycopersicon esculentum Mill. ） hybrid seed production techniques under plastic shed cultivation. The results showed that influencing degree of the three factors on the yields and quality of tomato seeds were plant density 〉 pollination times 〉 pruning way, and the best combination could be obtained by density of 3 340 plant per 667 m^2, with double-stem pruning and three times pollination.
