Effect of Biogas Manure on Yield and Quality of Strawberry in Greenhouse

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;treatmentⅠwith 1 500kg/ha chemical fertilizer as basal fertilizer,urea as topdressing;treatmentⅡ,Ⅲ,Ⅳwith 60 000kg/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,treatmentⅢ reached up to 36 570kg/ha,which was 103.2%,15%,13.1%,14.2% more than the CK,treatmentⅠ,ⅡandⅣ,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.
