摘要： 为研究土壤施硒对番茄果实品质的影响，采用2个不同品种番茄为供试材料，向土壤中施入硒酸钠、亚硒酸钠2种硒源，硒源浓度分别为0、7.5、15、22.5 g/hm2，测定成熟果实5项基本品质指标。结果表明：施硒后番茄果实中可溶性固形物、Vc、可溶性糖、糖酸比及可溶性蛋白含量基本高于对照，且随施硒浓度的增大，各指标大体呈先升高后降低的趋势；施硒酸钠效果好于亚硒酸钠；大番茄品质提高效果好于小番茄；2个品种的最优硒处理分别为15 g/hm2 Na2SeO4及7.5 g/hm2 Na2SeO4。

Abstract: The objective of this experiment was to study the effect of application of selenate and selenite to soil on the fruit quality of tomato. Two different varieties of tomato were employed as the testing materials. Selenate and selenite were applied to the soil with various concentrations (0, 7.5, 15, 22.5 g/hm2), and then five basic quality indicators of ripe tomato fruits were measured. The results showed as follows: the concentration of soluble solids, vitamin C, soluble sugar, sugar acid ratio and soluble protein in test group, which was treated by Se-fertilizer, was higher than that of the control group. With the increasing concentration of Se, an approximate trend of all five indicators, which has increased first and then decreased, has been observed. This suggested that the effect of selenate was better than the effect of selenite and the first species (the tomato of large size) was better than the second (the tomato of small size). The results indicated that the best treatment for the first species of tomato and the second species of tomato was selenate with 15 g/hm2 and selenite with 7.5 g/hm2, respectively.
