| 中文摘要:探讨追施沼肥对番茄生长、产量和品质的影响，旨在为日光温室栽培追施沼肥在番茄上的应用提供理论依据。采用裂区设计，研究主栽蔬菜—番茄在日光温室种植条件下，追施不同量的沼肥和喷施不同体积分数的沼液对番茄生长、产量和品质的影响。结果表明，在喷施沼液体积分数相同的条件下，追施75 t·hm-2沼肥促进番茄植株的生长，提高番茄的硬度、单果质量、产量、维生素C质量分数、可溶性糖质量分数和糖酸比，且优于常规施肥（CG），有效改善番茄品质，提高经济效益。在沼肥追施量一致的条件下，喷施体积分数为50%的沼液为最优。在二因素交互作用下，喷施沼液的体积分数为50%、沼肥追施量为75 t·hm-2时，有利于番茄的生长、增产和品质的改善。 |

| Abstract:We investigated the effect of topdressing biogas fertilizer on growth,yield and quality of tomato,so as to provide theoretical basis for the biogas fertilization to tomato in greenhouse.With split plot design,the growth,yield and quality of tomato in greenhouse affected by different topdressing amounts and spraying concentrations of biogas fertilizer were analyzed.The results showed that under same concentration,topdressing 75 t·hm-2 biogas fertilizer promoted the growth of tomato plants,the tomato hardness,yield,vitamin C mass fraction,soluble sugar mass fraction and sugar acid ratio,and it was better than conventional fertilization.It also improved tomato quality and increased economic benefit.By consistent topdressing amount of biogas fertilizer,spraying biogas slurry with volume of 50% was the best.Under the condition of the interactive effect of topdressing and spraying fertilizer,the volume fraction of the spraying biogas slurry was 50% and topdressing biogas fertilizer was 75 t·hm-2,and this was benificial to increase growth,yield and quality of tomato. |
