通过3年的试验，研究了在典型低硫土壤上施用农家肥（FYM）和硫对大豆根瘤产量、根瘤干重、叶绿素含量、干物质生产和籽粒产量的影响。FYM在大豆上以0-16 t ha（-1）4个水平施用。大豆和小麦每年也以石膏形式施硫，施量为0-60 kg/ha。FYM和S均能显著提高大豆根瘤的总产量、活性根瘤产量、根瘤干重、干物质生产量和籽粒产量。然而，当施用量超过8吨FYM和40公斤S/ha（-1）时，总结核与活性结核的比例急剧下降。
In a 3-year experiment on a Typic Haplustert low in soil test sulphur (S), the response to applied farmyard manure (FYM) and S was studied in terms of the nodule production, nodule dry weight, chlorophyll content, dry matter production and seed yield of soybean. FYM was applied to soybean at four levels (0-16 t ha(-1)). S as gypsum was also applied at four levels (0-60 kg ha(-1)) to both soybean and wheat every year. Both total and active nodule production, nodule dry weight, dry matter production and seed yield of soybean were increased significantly by the application of both FYM and S. However, the proportion of total nodules to active nodules fell sharply for applications higher than 8 t FYM and 40 kg S ha(-1).
