| 摘 要： | 试验结果表明:硫素不足(土壤硫用量<0.18g/kg)可使烤烟叶片可溶性蛋白质含量降低;不施硫或高硫(土壤硫用量>0.18g/kg)都会使叶片氨基酸含量降低。施用硫37.5~112.5kg/hm2的,明显促进烤烟生长,其中以硫75.0kg/hm2用量的最佳,其烟叶产量和产值分别比对照增加11.73%、10.67%;硫用量达到225.0kg/hm2的烟叶产量、产值分别比硫用量75.0kg/hm2的下降18.77%、17.14%,上等烟比例下降9.9个百分点。

| Abstract: | The experiment results showed that sulfur deficiency, especially fertilized less sulfur than 0.18g/kg, decreased soluble-protein content in flue-cured tobacco leaves. Meanwhile the amino-acids content was decreased on the conditions that sulfur fertilizer was deficient, and the addition of sulfur fertilizer was beyond 0.18 g/kg. The sulfur fertilizer of 37.5~112.5 kg/hm2 improved effectively the flue-cured tobacco. And the treatment with 75.0 kg/hm2 was recommended for flue-cured tobacco, yield and income increased by 11.73%, 10.67% than that of CK. If sulfur fertilizers increased to 225.0 kg/hm2, yield and income decreased 18.77%, 17.14% respectively compared with the treatment of 75.0 kg/hm2, the ratio of high- rate leaves also decreased by 9.9%. |
