通过田间试验研究了S缓释硫营养对花生品种生长、酶活性和产量性状的影响。采用两种硫肥组合(以公斤/公顷计)：S(-S)和20S(+S)。在+S处理中，花生田一次性基施S。结果表明，与不喷施S(-S)相比，喷施S(+S)显著提高了两个品种各生育期的生物量积累。硝酸还原酶(NR)和三磷酸腺苷-硫化酶(ATP-Sulurylase)在播种后45d迅速升高，之后逐渐下降。根瘤重和固氮酶活性在75DAS时增加，此后下降。S施肥对根瘤硝酸还原酶、三磷酸腺苷-硫化酶、根瘤重和固氮酶活性有较好的影响。S缓释肥还能提高种子产量、生物产量和收获指数。
Field experiments were presently conducted to investigate the effect of slow release sulphur (S) nutrition on crop growth, enzyme activities and yield attributes in peanut cultivars. Two combinations of sulphur (in Kg/ha): 0S (-S) and 20S (+S) were used. In +S treatment, S was applied as a single basal dose in the field of peanut crop. The results showed that application of S (+S) significantly (P<0.05) increased the biomass accumulation in both the genotypes at all the growth stages compared with without S (-S). Rapid increases of nitrate reductase (NR) and ATP-sulphurylase were observed up to 45 days after sowing (DAS), and thereafter decline. Nodule weight and nitrogenase activity was increased up to 75 DAS and thereafter, these parameters declined. S fertilization favorably influenced NR, ATP-sulphurylase, nodule weight and nitrogenase activity. Seed yield, biological yield and harvest index were also enhanced by slow S-release fertilization.
