摘　　要：文章通过对日光温室辣椒喷施不同浓度的沼液、冲施不同量的沼渣沼液,研究沼渣沼液对提高辣椒生长及产量的影响。结果表明：叶面喷施沼液有增加辣椒株高、茎粗的趋势,沼渣原液喷施显著提高辣椒功能叶片叶绿素含量,产量提高8.2%。冲施沼渣沼液300～450 kg能显著增加辣椒株高、茎粗,功能叶片叶绿素含量,产量提高12%左右。因此,日光温室蔬菜应采用沼液原液喷施或每666.7 m2冲施沼渣沼液300～450 kg。Biogas slurry and biogas residue were applied with different amount to grow peppers in greenhouse,and their effect on the pepper growth and yield were investigated. The results showed that the foliage spray of biogas slurry without dilution on pepper plant could increase the plant height and diameter,improve the leaf chlorophyll content,and raise the yield by 8. 2%. And the biogas residue of 300 ～ 450 kg per 666. 7 m2 applied to pepper could also obtain the similar improving,and the yield raised by 12 %.
