| 摘 要： | 研究了小麦-油菜轮作生产体系中选择连续种植三年油菜、两年小麦以及小麦-油菜-小麦轮作等三种不同种植方式对土壤有效硫含量的影响,结果表明,三种不同种植方式下土壤有效硫含量全部低于临界水平(20 mg/kg);6年内土壤有效硫含量降低一半.施硫可增加小麦的穗长、穗粒数,增加油菜单株结荚数、角果长和角粒数,从而增加了小麦和油菜的产量,施硫45kg/hm2 使小麦、油菜产量的增幅分别为6.5;～17.3;和25.4;～51.3;.

| Abstract: | There are three different rotation planting methods in the experiment for field production under the condition of growing crops such as rotation planting rape for three years in succession;rotation planting wheat for two years in succession and rotation planting wheat-rape-wheat in succession.The effect of the three rotation planting methods on the amount of the available sulphur in the soil was studied.The results indicated that the total available sulphur content under the three different rotation planting methods was lower than critical level(20 mg/kg);The available sulphur content in the soil was decreased by 50% within 6 years.The length of spike,grains per panicle of wheat and pods per rape plant,length and grains of horngfruit could be increased by application sulphur fertilizer.Thereby,the yield of wheat and rape were increased by 6.5%～17.3% and 25.4%～51.3% respectively. |
