摘　　要：为了研究不同沼肥组合对大棚草莓产量及果实品质的影响,设5个处理,对照不施任何肥,追肥以清水为主,处理Ⅰ底肥施入化肥1 500kg/hm2(尿素600kg/hm2+硫酸钾450kg/hm2+二铵450kg/hm2),追施尿素;处理Ⅱ、Ⅲ、Ⅳ基肥均施沼渣60 000kg/hm2,各处理生长期分别使用40%、60%、80%沼液追肥。结果表明:使用沼渣作基肥、喷施不同浓度沼液追肥的草莓移栽成活率均高达100%,且能促进植株生长,降低烂果率,提高商品性能;在产量方面,处理Ⅲ高达36 570kg/hm2,产量和收益分别比CK、处理Ⅰ、Ⅱ、Ⅳ提高18 570kg、4 770kg、4 230kg、4 545kg和103.2%、15%、13.1%和14.2%,经济效益十分明显。表明,以沼渣为基肥,喷施沼液作追肥,草莓果色鲜红,烂果率低,商品性好,其中沼渣施入60 000kg/hm2,沼液追肥喷施浓度为60%时草莓商品性最好。In order to study the effect of biogas manure on yield and fruit quality of strawberry in greenhouse,five treatment combinations were designed, which were CK without fertilizer; treatment I with 1 500 kg/ha chemical fertilizer as basal fertilizer, urea as topdressing; treatment II , III, IV with 60 000 kg/ha biogas residue as basal fertilizer, 40%, 60%, 80% biogas slurry as topdressing, respectively. The results showed that when biogas residue was used as basal fertilizer, biogas slurry was used as topdressing, the survival rate of strawberry plantlets reached up to 100 %, plant growth was promoted, rotten fruit rate was reduced and the product performance was improved. In the aspect of yield, treatment III reached up to 36 570 kg/ha, which was 103.2%, 15% ,13.1% ,14.2% more than the CK,treatment I, II and IV ,respectively,the economic benefit was significant. Overall, the color of strawberries was red brightly, rotten fruit rate was lower, and marketability was good with biogas residue as basal fertilizer,biogas slurry as topdressing, especially with 60% biogas slurry spraying topdressing.
