摘　　要：在盆栽条件下，研究了不同配方叶面肥对辣椒生长及产量和品质的影响。结果表明，不同配方叶面肥均可显著增加辣椒的产量，与清水对照相比，增产12．0％～24．6％，并显著提高植株N、P、K的含量。适当浓度的芸苔素内酯和营养物质配合，可显著促进辣椒植株的生长，提高辣椒叶片中叶绿素含量及叶片的净光合速率，增加植株的生物产量，并能够提高果实维生素C和可溶性糖含量，降低硝酸盐含量，使果实品质得到显著改善。营养物质和芸苔素内酯与微量元素配合，在促进辣椒植株生长、提高果实产量及改善品质方面，可达到最理想施肥效果。A pot experiment was carried out to study the effects of different foliar fertilizers on the growth and yield and quality of Capsicum annuum L. The results obtained were listed as follows： the application of different foliar fertilizers could increase chili yield, 12.0%-24. 6% higher than that of water control, and markedly increase N, P and K contents in the plants. The foliar applications of suitable concentration of brassinolide and nutrient substance significantly increased plant growth, enhanced chlorophyll content and net photosynthetic rate of chili leaves and increased the biomass of plants, improved contents of vitamin C, soluble sugar and decreased the content of nitrate in chili fruit, improve significantly the fruit quality. The rational mixture of nutrient substance and microelements with brassinolide had the most optimum results in effects of stimulating its growth, increasing the yield and improving fruit quality.
