摘要
不同品种硫肥在大豆上的试验结果表明 :硫对大豆的生长发育有促进作用 ,并能提高产量 ,增产效果较好的是硫铵和硫黄 ,增产 6 4 %～ 11 4 %。不同用量硫肥在大豆上的应用效果表明 :随着硫肥施用量的增加 ,大豆的产量增加 ,S2 增加 6 6 %～ 8 6 % ,S4 增加 9 2 %～ 10 6 %。另外 ,施含硫肥料能缓解土壤硫素的消耗 。
The study showed that applying fertilizer could promote the soybean growth and increase its yield.The effect of ammonia sulfate and element sulphur were wht best of all the 4 treatments. The yields increased 6 4% and 11.4% separately. The soybean yield improved with tne increase of applying sulphur amount. In addition, applying sulphur fertilizer could decrease available sulphur consumption in soil and play an important role in keeping the balance of sulphur in soil.
