| 摘 要： | 通过对设施番茄、甜椒施用不同比例的沼渣沼液和化肥,研究沼渣沼液替代化肥的农学效果和对土壤养分积累的影响。结果表明:施用沼渣沼液部分替代化肥并没有导致果类蔬菜果实产量、品质发生明显下降,在本试验条件下完全施用沼渣沼液可以满足作物正常的生长发育,但分析周年设施菜田土壤的N、P、K养分盈余和养分损失等指标发现,施用沼渣沼液处理的土壤氮、磷养分盈余,表层土壤出现磷累积并出现氮素淋洗损失等问题,因此限制性施用沼渣沼液是今后在菜田可持续生产中需要注意的问题。

| Abstract: | As the byproduct of biogas projects,biogas wastes have the advantages of multiple nutrient and stable supply.Greenhouse vegetable field may be the main consumptive place for biogas waste.Greenhouse experiment with double cropping system was carried out to study the effects of partial chemical fertilizer substituted by biogas wastes on solanaceae vegetables growth and soil nutrient accumulation.The results showed that no significant differences were investigated in vegetable growth and fruit yield among diff... |
