盆栽试验结果表明，在低硫和低氮土壤上，单独施用氮和硫，对小麦的干物质产量没有影响，配合施用显著地增加于物质产量，也显著提高植株氮硫含量和吸收量。获得小麦最大干物质产量的氮硫适宜用量分别为200μg/g和20~40μg/g，再增加用量导致干物质产量下降。最大干物质产量的土壤适宜N／S为4.0－14.0，
The results of pot experiment showed that the application of nitrogen and sulfur alone had no effect on the dry matter yield of wheat in low sulfur and low nitrogen soils. The application of nitrogen and sulfur significantly increased the material yield and significantly increased the nitrogen and sulfur content and absorption of the plant. The optimum amount of nitrogen and sulfur to obtain the maximum dry matter yield of wheat was 200μg / g and 20 ~ 40μg / g, respectively, and the increase of the dosage resulted in the decrease of dry matter yield. The maximum dry matter yield of soil suitable N / S is 4.0-14.0,
