Municipal solid waste compost (MSWC) and/or fertigation used in greenhouse pepper (Capsicum annuum L.) cultivation with five different substrates with soil (S) and/or MSWC mixtures (0-5-10-20-40%) used with or without fertigation. Plants growth increased in 10-20% MSWC and fertigation enhanced mainly the plant height. Fruit number increased in S : MSWC 80 : 20 without fertilizer. Plant biomass increased as MSWC content increased. There were no differences regarding leaf fluoresces and plant yield. The addition of MSWC increased nutritive value (N, K, P, organic matter) of the substrate resulting in increased EC. Fruit fresh weight decreased (up to 31%) as plants grown in higher MSWC content. Fruit size fluctuated when different MSWC content used into the soil and the effects were mainly in fruit diameter rather than in fruit length. Interestingly, the scale of marketable fruits reduced as MSWC content increased into the substrate but addition of fertilizer reversed this trend and maintained the fruit marketability. MSWC affected quality parameters and reduced fruit acidity, total phenols but increased fruit lightness. No differences observed in fruit dry matter content, fruit firmness, green colour, total soluble sugars and EC of peppers and bacteria (total coliform and E. coli) units. Low content of MSWC improved plant growth and maintained fruit fresh weight for greenhouse pepper without affecting plant yield, while fertigation acted beneficially.
在温室辣椒（Capsicum annuum L.）种植中，使用城市固体废弃物堆肥（MSWC）和/或进行施肥灌溉，采用五种不同的基质，即土壤（S）和/或MSWC混合物（0 - 5 - 10 - 20 - 40%），有施肥灌溉或无施肥灌溉。在含有10 - 20% MSWC的情况下，植株生长加快，施肥灌溉主要提高了株高。在不施肥的情况下，S:MSWC为80:20时果实数量增加。植物生物量随MSWC含量的增加而增加。叶片荧光和植物产量方面没有差异。添加MSWC提高了基质的营养价值（氮、钾、磷、有机质），导致电导率升高。当植株生长在MSWC含量较高的环境中时，果实鲜重下降（高达31%）。当向土壤中添加不同含量的MSWC时，果实大小波动，其影响主要体现在果实直径而非果实长度上。有趣的是，随着基质中MSWC含量的增加，可销售果实的比例降低，但施肥可扭转这一趋势并维持果实的适销性。MSWC影响品质参数，降低了果实酸度、总酚含量，但增加了果实亮度。辣椒的果实干物质含量、果实硬度、绿色、总可溶性糖和电导率以及细菌（总大肠菌群和大肠杆菌）单位方面未观察到差异。低含量的MSWC可促进温室辣椒的植株生长并维持果实鲜重，且不影响植株产量，而施肥灌溉则起到有益作用。
