摘　　要：通过盆栽试验,研究了叶面喷施自行研制的波尔多液营养保护剂(BNPP)、美国商品铜制剂Kocide2000(KCD)、传统波尔多液(BDM)对辣椒生长效应的影响。结果表明:喷施BNPP能显著提高辣椒的产量,低、高浓度处理与CK1和CK2相比分别提高74.7%和26.7%、59.4%和15.6%,以稀释1000倍液的低浓度处理效果最佳;喷施KCD也能促进辣椒叶面积、叶绿素含量及产量的提高,但效果不如BNPP;喷施传统波尔多液则抑制辣椒叶面积和叶绿素含量的增长。Pot experiments were conducted to study the effects of spraying three kinds of copper agents： Bordeaux Mixture （BDM）, Kocide2000 （KCD）, Bordeaux Nutritional Protective Powder （BNPP） , on surface of chilli leaves with different concentrations. The results showed that spraying BNPP at certain intervals significantly increased the yield of chilli, and two different concentrations of BNPP increased the yield by 74.7 % and 26.7 % , 59.4 % and 15.6 % , respectively, as compared to the control. Compared with the spraying concentration of 2 g·L^-1, the concentration of 1 g·L^-1 received better results in the treatments. In comparison, the treatments with spraying KCD at different concentrations promoted the growth of chilli as well, though unparalleled with the BNPP. However, the spraying of BDM inhibited the growth of chilli in leaf area and the content of chlorophyl.
