【摘要】 116个土壤样品分析结果表明 ,闽东南地区耕地土壤有效硫平均含量为 2 1.7mg· kg- 1。其中 ,小于 16mg· kg- 1 的临界指标的样品占总样品数的 5 7.8%。田间试验结果 ,水稻、甘薯和花生在每公顷施硫 2 0~ 6 0 kg范围内 ,都有不同程度的增产效果 ,增幅分别为 2 .9%~ 15 .5 %、 5 .6 %~ 2 2 .4 %和 2 .6 %~ 34.5 % ,且具有一定后效。同时 ,施用硫肥还改善了农产品品质 ,花生粗脂肪、粗蛋白 ,甘薯粗蛋白等的含量都有一定提高

【Abstract】 The average of available S in 116 soil samples from cultivated soils of southeast Fujian was 21 7 mg·kg -1 , and the soils whose available S contents were lower than critical value(16 mg·kg -1 ) accounted for 57 8% of cultivated soils in southeast Fujian.The result of field test showed that there were different yieldincreasing efficiency by applying S 20-60 kg·hm -2 to the plants of rice, sweet potato and peanut, etc The increasing ratio of rice,sweet potato,peanut were 2 9%-15 5%, 5 6%-22 4%, 2 6%-34 5%, respectively Post\|effect was abserved.Meanwhile, applying S fertilizer improved the quality of farm products, such as crude fat, crude protein in peanut and sweet potato, and so on.
