摘　　要：2013--2014年采用盆栽试验研究了不同种类及浓度的铜基营养保护剂对棉花生长、产量及防病效果等的影响。结果表明：4种铜基营养保护剂在喷施质量浓度为1g·L-1和2g·L-1时，与喷施清水相比，皮棉产量分别增加4．22％～13．38％和21．89％～38．36％；增加了棉株地上部干物质质量，最高达23．96％；降低了棉花病情指数26．75％～40．91％和22．78％～37．78％，但处理问差异不显著。因此，在棉花上喷施铜基营养保护剂既可促进棉花生长，增加棉花产量。又可提高棉花的防病效果。To explore the effects of copper-based protective agents on the growth, yield, and disease control efficiency of cotton,pot experiments were conducted in 2013 and 2014. The results showed that the lint yield was increased by 4.22%-13.38% and21.89%-38.36% by spraying four kinds of copper-based protective agents on leaves with the concentration of 1 g·L-1and 2 g·L-1, respectively, compared with water. The aboveground dry matter weight of cotton plants was improved by 7.44%-19.38%and 10.25%-23.96%, compared with spraying water on the leaves. Additionally, the disease index was reduced by 26.75%-40.91%and 22.78%-37.78% by spraying copper-based protective agents on the leaves, compared with water. There was no difference among the different kinds of treatments. Based on these analyses, we conclude that the application of different concentrations and kinds of copper-based protective agents can promote cotton growth and production. Also, the copper-based protective agents had favorable disease control efficiency for cotton Verticillium wilt. Thus, these copper-based protective agents have good application value.
