摘要： 硫是生物体重要组成成分，与大豆膳食纤维代谢密切相关，确定最佳施硫量，对改善大豆品质，提高大豆营养价值具有重要意义。为研究不同施硫量对不同基因型大豆膳食纤维含量的影响，以黑龙江省3个主栽大豆品种,‘黑农37’（HN37，中间型品种）、‘黑农44’（HN44，高油品种）、‘黑农48’（HN48，高蛋白品种）为试验材料，采用盆栽，每个品种设4个处理组（即每Kg土壤分别施单质硫0、0.02、0.04、0.06，即S1、S2、S3、S4）。采用酶-重量法测定不同大豆品种籽粒总膳食纤维的含量。结果表明：同一品种不同处理大豆总膳食纤维含量， HN48和HN37在S3处理含量最高，HN44在S2处理含量最高；同一处理不同品种间大豆总膳食纤维含量，在4个施硫条件下均表现出HN48含量最高，其次是HN37和HN44；在不同品种不同处理中，大豆总膳食纤维含量峰值出现在HN37的S3水平下；施硫对3个大豆品种膳食纤维含量有影响，合理适量的施硫可有效提高大豆籽粒膳食纤维的含量。

Abstract: Sulfur is one of important constituents in organisms. It is closely related to metabolism of soybean dairy fiber, so the proper sulfur dose in fertilizer is important for improving soybean nutrient and quality. For evaluating the effect of different sulfur dose on dairy fiber in various soybean gene type,Three soybean varieties in Heilongjiang ( ‘Heinong-37’, middle cultivar; ‘Heinong-44’, high-oil cultivar and ‘Heinong-48’, high-protein cultivar) were investigated. The soybean seeds were planted in pots. 4 levels of sulfur (S) treatment weredesigned, which were S1, S2, S3 and S4 (0, 0.02, 0.04, 0.06 g of sulfur per kilogram of soil). The content of total Dietary fiber in different soybean varieties was determined by enzyme-weight measurement. The results showed that, the content of total Dietary fiber under the same variety of different treatment, HN48 and HN44 treatment was significantly higher than that of S3, HN37 in S2 processing under the highest content; same deal with the different varieties of soybean total Dietary fiber content, under the S1-S4 treatment HN48 was significantly highest, and then HN37 and HN44. Under different treatments in different soybean varieties, the content of total Dietary fiber in HN37 S3 was the highest. These findings suggested that Sulfur affected the total content of Dietary fiber in the three soybean varieties, and appropriate amounts of S fertilization might contribute to improving the content of Dietary fiber.
