| 摘 要： | 通过对四川省 6类 32 9个土壤样品的有效硫的分析 ,结果表明缺硫及潜在性缺硫土样占总样本的 2 3 1 % .但结合田间试验 ,在四川盆地特定环境条件下 ,即使土壤耕层有效硫处于缺乏范围 ,增施硫肥对玉米、小麦、油菜产量无明显增加 ,并就产生的原因作了初步分析 .通过对土壤硫素平衡的测算 ,预测在近期内 ,四川盆地主要农耕地不会发生大面积缺硫问题

| Abstract: | We analyzed available sulfur contents of 329 soil samples taken from Sichuan province. Only 23 1% of the samples were of sulfur deficiency deficit or of potential sulfur deficiency. Field experiments showed that sulfur application had different effects in the different environments of Sichuan Basin. We therefore concluded that the cultivated soils of Sichuan Basin will be still of S deficit in near future according to the calculation of soil sulfur balance. |
