摘　　要：为了提高葡萄产量以及控制土壤障碍因子的发生,采用土壤消毒剂1号在葡萄园进行不同用量的对比试验。结果表明:土壤消毒剂1号450～900kg/hm2结合施45%葡萄专用肥750kg/hm2,比不施土壤消毒剂1号对照(施45%复合肥750kg/hm2)提高葡萄产量20.7%～28.6%,提高经济效益19.8%～28.6%;有效防治白腐病、炭疽病、霜霉病危害。4个不同量处理比对照处理减少的白粉病、炭疽病、霜霉病危害率分别为73.7%、78.9%、78.9%和78.9%,明显提高防病效果。同时更进一步表明,以750kg/hm2施用量对葡萄产量和经济效益及防病效果达到最佳。The comparative experiment on the application rates of soil decontaminant（Ⅰ） was performed to determine its disease control effect and influence on the yield of grapes after it was applied in the vinery.The results showed that the yield of grapes at the application rate of 450-900 kg/hm2 plus 45% compound fertilizer at 750 kg/hm2 increased by 20.7%-28.6% in comparison with that under CK without the application of soil decontaminant（Ⅰ）,together with the increased economic returns 19.8%-28.6% and the significant control effect on powdery mildew,anthracnose and downy mildew.Under the four application rates of soil decontaminant（Ⅰ）,the damage rates of powdery mildew,anthracnose and downy mildew reduced respectively by 73.7%,78.9%,78.9%,and 78.9% compared with CK without the application of soil decontaminant（Ⅰ）.The results also showed that,an optimum combination of grape yield,economic returns and disease control effect could be obtained at 750 kg/hm2 application rate of soil decontaminant（Ⅰ）.
