摘　　要：以樱桃番茄为材料,研究了6个硒处理浓度(0,2,4,6,8,10 mg/L)对不同品种樱桃番茄的富集性及单果质量的影响。研究结果表明,低浓度的硒(0～4 mg/L)对樱桃番茄的生长发育起促进作用,其中当硒浓度为4 mg/L时,樱桃番茄的单果质量最大,以红色樱桃番茄对硒的富集性最强,但高浓度的硒(>4 mg/L)对其有一定的抑制作用。另设4种施硒方式,研究了相同硒浓度下(4 mg/L),不同施硒方式(CK,土施,根外追肥,混施)对不同品种樱桃番茄的单果质量和可溶性固形物含量的影响。研究结果表明,不同施硒方式对不同品种的樱桃番茄的发育影响不同,其中以混施方式效果最好,且对红色樱桃番茄发育影响最大,其产量和可溶性固形物含量高于对照和其他品种。The effects of 6 selenium concentrations（0,2,4,6,8,10 mg/L） on the enrichment and single fruit weight of different cherry tomato cultivars were studied.The results showed that low concentrations of selenium（0-4 mg/L） played catalytic roles on the growth of cherry tomatoes,and the single fruit was the heaviest with the selenium concentration at 4 mg/L,and the red cherry tomato had the best enrichment,while higher concentrations of selenium（4 mg/L） played negative roles.Meanwhile,4 different fertilization modes of selenium（CK,soil application,foliage spray,mixed fertilization） were set to learn their effects on the single fruit weight and soluble solid content of different cherry tomato cultivars.The results showed that their effects on different cultivars were not alike,with the mixed fertilization mode having the best effect,and the development of the red cherry tomato was affected greatest,the yield and soluble solid content of which was the highest.
